CO2 to SAF: A One-Step Solution
The title of this post is the same as that of this article on the Chemical Engineer.
This is the sub-heading,
Oxford spinout OXCCU has launched a demonstration plant at London Oxford Airport to trial its one-step process of turning CO2 into sustainable aviation fuel (SAF). Aniqah Majid visited the plant to investigate the benefits of its “novel” catalyst
One word in this sub-heading caught my eye.
When I was a young engineer in the Computer Techniques section in the Engineering Department at ICI Plastics Division, I did a small mathematical modelling project for this chemical engineer, using the section’s PACE 231-R analogue computer.
He was impressed and gave the 23-year-old self some advice. “You should apply that beast to catalysts.”
I have never had the chance to do any mathematically modelling of catalysts either at ICI Plastics or since, but I have invested small amounts of my own money in companies working with advanced catalysts.
So when OXCCU was picked up by one of my Google Alerts, I investigated.
I like what I found.
The three raw ingredients are.
- Green Hydrogen
- Carbon dioxide perhaps captured from a large gas-fired powerstation like those in the cluster at Keadby.
- OXCCU’s ‘novel’ catalyst, which appears to be an iron-based catalyst containing manganese, potassium, and organic fuel compounds.
I also suspect, that the process needs a fair bit of energy. These processes always seem to, in my experience.
This paragraph outlines how sustainable aviation fuel or (SAF) is created directly.
This catalyst reduces CO2 and H2 into CO and H2 via a reverse water gas shift (RWGS) process, and then subsequently turns it into jet fuel and water via Fischer-Tropsch (FT).
The Wikipedia entry for Fischer-Tropsch process has this first paragraph.
The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons.
Note.
- I wouldn’t be surprised that to obtain the carbon monoxide and hydrogen or syngas for the Fischer-Tropsch process, excess hydrogen is used, so the OXCCU process may need a lot of affordable hydrogen, some of which will be converted to water in the RWGS process.
- The high temperatures and pressures for the Fischer-Tropsch process will need a lot of energy, as I predicted earlier.
But I don’t see why it won’t work with the right catalyst.
The Wikipedia entry for the Fischer-Tropsch process also says this.
Fischer–Tropsch process is discussed as a step of producing carbon-neutral liquid hydrocarbon fuels from CO2 and hydrogen.
Three references are given, but none seem to relate to OXCCU.
OXCCU have a web site, with this title.
Jet Fuel From Waste Carbon
And this mission statement underneath.
OXCCU’s mission is to develop the world’s lowest cost, lowest emission pathways to make SAF from waste carbon, enabling people to continue to fly and use hydrocarbon products but with a reduced climate impact.
It looks like they intend to boldly go.
Conclusion
My 23-year-old self may have been given some good advice.
The Thoughts Of Chris O’Shea
This article on This Is Money is entitled Centrica boss has bold plans to back British energy projects – but will strategy pay off?.
The article is basically an interview with a reporter and gives O’Shea’s opinions on various topics.
Chris O’Shea is CEO of Centrica and his Wikipedia entry gives more details.
These are his thoughts.
On Investing In Sizewell C
This is a paragraph from the article.
‘Sizewell C will probably run for 100 years,’ O’Shea says. ‘The person who will take the last electron it produces has probably not been born. We are very happy to be the UK’s largest strategic investor.’
Note.
- The paragraph shows a bold attitude.
- I also lived near Sizewell, when Sizewell B was built and the general feeling locally was that the new nuclear station was good for the area.
- It has now been running for thirty years and should be good for another ten.
Both nuclear power stations at Sizewell have had a good safety record. Could this be in part, because of the heavy engineering tradition of the Leiston area?
On Investing In UK Energy Infrastructure
This is a paragraph from the article
‘I just thought: sustainable carbon-free electricity in a country that needs electricity – and we import 20 per cent of ours – why would we look to sell nuclear?’ Backing nuclear power is part of O’Shea’s wider strategy to invest in UK energy infrastructure.
The UK certainly needs investors in UK energy infrastructure.
On Government Support For Sizewell C
This is a paragraph from the article.
Centrica’s 500,000 shareholders include an army of private investors, many of whom came on board during the ‘Tell Sid’ privatisations of the 1980s and all of whom will be hoping he is right. What about the risks that deterred his predecessors? O’Shea argues he will achieve reliable returns thanks to a Government-backed financial model that enables the company to recover capital ploughed into Sizewell C and make a set return.
I have worked with some very innovative accountants and bankers in the past fifty years, including an ex-Chief Accountant of Vickers and usually if there’s a will, there’s a solution to the trickiest of financial problems.
On LNG
These are two paragraphs from the article.
Major moves include a £200 million stake in the LNG terminal at Isle of Grain in Kent.
The belief is that LNG, which produces significantly fewer greenhouse gas emissions than other fossil fuels and is easier and cheaper to transport and store, will be a major source of energy for the UK in the coming years.
Note.
- Centrica are major suppliers of gas-powered Combined Heat and Power units were the carbon dioxide is captured and either used or sold profitably.
- In at least one case, a CHP unit is used to heat a large greenhouse and the carbon dioxide is fed to the plants.
- In another, a the gas-fired Redditch power station, the food-grade carbon dioxide is sold to the food and construction industries.
- Grain LNG Terminal can also export gas and is only a short sea crossing from gas-hungry Germany.
- According to this Centrica press release, Centrica will run low-carbon bunkering services from the Grain LNG Terminal.
I analyse the investment in Grain LNG Terminal in Investment in Grain LNG.
On Rough Gas Storage
These are three paragraphs from the article.
O’Shea remains hopeful for plans to develop the Rough gas storage facility in the North Sea, which he re-opened in 2022.
The idea is that Centrica will invest £2 billion to ‘create the biggest gas storage facility in the world’, along with up to 5,000 jobs.
It could be used to store hydrogen, touted as a major energy source of the future, provided the Government comes up with a supportive regulatory framework as it has for Sizewell.
The German AquaVentus project aims to bring at least 100 GW of green hydrogen to mainland Germany from the North Sea.
This map of the North Sea, which I downloaded from the Hydrogen Scotland web site, shows the co-operation between Hydrogen Scotland and AquaVentus
Note.
- The yellow AquaDuctus pipeline connected to the German coast near Wilhelmshaven.
- There appear to be two AquaDuctus sections ; AQD 1 and AQD 2.
- There are appear to be three proposed pipelines, which are shown in a dotted red, that connect the UK to AquaDuctus.
- The Northern proposed pipeline appears to connect to the St. Fergus gas terminal on the North-East tip of Scotland.
- The two Southern proposed pipelines appear to connect to the Easington gas terminal in East Yorkshire.
- Easington gas terminal is within easy reach of the massive gas stores, which are being converted to store hydrogen at Aldbrough and Rough.
- The blue areas are offshore wind farms.
- The blue area straddling the Southernmost proposed pipe line is the Dogger Bank wind farm, is the world’s largest offshore wind farm and could eventually total over 6 GW.
- RWE are developing 7.2 GW of wind farms between Dogger Bank and Norfolk in UK waters, which could generate hydrogen for AquaDuctus.
This cooperation seems to be getting the hydrogen Germany needs to its industry.
It should be noted, that Germany has no sizeable hydrogen stores, but the AquaVentus system gives them access to SSE’s Aldbrough and Centrica’s Rough hydrogen stores.
So will the two hydrogen stores be storing hydrogen for both the UK and Germany?
Storing hydrogen and selling it to the country with the highest need could be a nice little earner.
On X-energy
These are three paragraphs from the article.
He is also backing a £10 billion plan to build the UK’s first advanced modular reactors in a partnership with X-energy of the US.
The project is taking place in Hartlepool, in County Durham, where the existing nuclear power station is due to reach the end of its life in 2028.
As is the nature of these projects, it involves risks around technology, regulation and finance, though the potential rewards are significant. Among them is the prospect of 2,500 jobs in the town, where unemployment is high.
Note.
- This is another bold deal.
- I wrote in detail about this deal in Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors.
- Jobs are mentioned in the This is Money article for the second time.
I also think, if it works to replace the Hartlepool nuclear power station, then it can be used to replace other decommissioned nuclear power stations.
On Getting Your First Job
These are three paragraphs from the article.
His career got off to a slow start when he struggled to secure a training contract with an accountancy firm after leaving Glasgow University.
‘I had about 30, 40 rejection letters. I remember the stress of not having a job when everyone else did – you just feel different,’ he says.
He feels it is ‘a duty’ for bosses to try to give young people a start.
I very much agree with that. I would very much be a hypocrite, if I didn’t, as I was given good starts by two companies.
On Apprenticeships
This is a paragraph from the article.
‘We are committed to creating one new apprenticeship for every day of this decade,’ he points out, sounding genuinely proud.
I very much agree with that. My father only had a small printing business, but he was proud of the apprentices he’d trained.
On Innovation
Centrica have backed three innovative ideas.
- heata, which is a distributed data centre in your hot water tank, which uses the waste heat to give you hot water.
- HiiROC, which is an innovative way to generate affordable hydrogen efficiently.
- Highview Power, which stores energy as liquid air.
I’m surprised that backing innovations like these was not mentioned.
Conclusion
This article is very much a must read.
Mineral Carbonation International Changed Its Name To MCi Carbon In Early 2023
This post is to retrospectively sort out that Mineral Carbonation International changed its name to MCi Carbon in Early 2023.
Google AI gives this summary.
Mineral Carbonation International (MCi) changed its name to MCi Carbon in early 2023. The company’s rebranding emphasized its focus on commercializing and scaling its technology for carbon capture and utilization. The name change reflected a broader shift in the company’s strategy and market positioning.
They now have a web site at www.mcicarbon.com.
The old web site was at www.mineralcarbonation.com and the address now redirects to the new web site.
As I missed the name change, my last post on the company was Sumitomo Mitsui Trust Bank Makes Substantial Investment In Australia’s MCi Carbon.
I should probably have covered these stories earlier this year.
The world’s first CCU plant in the refractory industry
Japan’s MUCC Invests $5M In MCi Carbon To Advance Cement Decarbonization
MCi Carbon seems to be moving on.
North Sea Oil Group Equinor Scales Back Investment In Renewables
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Equinor, which is attempting to develop one of the largest untapped oilfields in UK waters, also raised its fossil fuel production targets
This is the first paragraph.
The Norwegian state-backed oil company that is attempting to develop one of the largest untapped oil fields in UK waters, has dramatically scaled back its investment in renewables and raised its fossil fuel production targets, becoming the latest of the world’s energy giants to row back on the push towards green power.
A quiet revolution is happening that will change our use of natural gas very much for the better.
- In Rhodesia, which is a suburb of Worksop, a 24 MW Rolls-Royce mtu diesel peaker power plant, that runs on natural gas, but is also hydrogen-ready, has been installed to boost the electricity supply. The diesel engine is fitted with carbon capture and produces food-grade CO2, which is sold for food and engineering uses.
- Most of the excellent British tomatoes and soft fruit, we have been eating this winter, is grown in greenhouses, heated by natural gas-powered combined heat and power units, where the CO2 produced is captured and fed to the plants.
- HiiROC is a start-up from Hull, who are backed by Centrica, who use a plasma process to split any hydrocarbon gas including waste gas from a chemical plant, biomethane from a sewage works or natural gas into pure hydrogen and carbon black, which is needed to manufacture tyres and other products, and also to improve soil.
- In the last few months, a HiiROC device has been installed at Brigg power station, to generate zero-carbon electricity from natural gas.
- Imagine a housing or factory estate, a farm or perhaps a large country house, that wants to decarbonise. The gas feed to the property would be fitted with a HiiROC device and all gas appliances and boilers would be converted to hydrogen.
- I also believe that houses and other premises could have their own hydrogen pumps to fill up cars, ride-on mowers and other vehicles.
- Avnos is a company from the US, that captures CO2 from the air. What makes Avnos unique is that for every ton of CO2 it captures, it captures five tons of pure water.
More ideas like these are being developed.
What is wrong in using natural gas, to generate heat and electricity, if it doesn’t emit any CO2 into the atmosphere?
I suspect, that Equinor believe there will be a market for natural gas for years, as more and more clever ways to use it and turn it into hydrogen are developed.
Energy In – Hydrogen And Carbon Dioxide Out
This article was inspired by this article in the Sunday Times, which is entitled ‘It’s A Slog’: Life Inside Britain’s Last Coal Power Station.
The article is about Ratcliffe-on-Soar power station, which is next to East Midlands Parkway station.
This is the first paragraph of the station’s Wikipedia entry.
Ratcliffe-on-Soar Power Station is a coal-fired power station owned and operated by Uniper at Ratcliffe-on-Soar in Nottinghamshire, England. Commissioned in 1968 by the Central Electricity Generating Board, the station has a capacity of 2,000 MW. It is the last remaining operational coal-fired power station in the UK, and is scheduled to close in September 2024.
I took these pictures of the power station in 2019.
Ratcliffe-on-Soar is the last of a number of large coal-fired power stations, that were built in the area, mainly along the River Trent.
- Rugeley – 600 MW – 1961
- Drakelow – 1630 MW – 1964
- Willington – 800 MW – 1962
- Castle Donington – 600 MW – 1958
- Ratcliffe-on-Soar – 2000 MW – 1968
- High Marnham – 1000 MW – 1959
- Cottam – 2000 MW – 1968
- West Burton – 2000 MW – 1968
Note.
- The date is the commissioning date.
- That is 10,630 MW of electricity.
- There are also a few large gas-fired power stations along the river, that are still operating.
- Both coal and gas-fired stations use the water from the River Trent for cooling.
At the mouth of the river, there is the Keadby cluster of gas-fired power stations.
- Keadby 1 – 734 MW – 1996
- Keadby 2 – 849 MW – 2023
- Keadby 3 – 910 MW – 2027
- Keadby Hydrogen – 900 MW – 2030
Note.
- The date is the commissioning date.
- That is 3,393 MW of electricity.
- Keadby 2 is the most efficient CCGT in the world.
- Keadby 3 will be fitted with carbon capture.
- Keadby 2 has been designed to be retrofitted with carbon capture.
- Keadby Hydrogen will be fuelled by zero-carbon hydrogen.
As the years progress, I can see the Keadby cluster of power stations becoming a large zero-carbon power station to back-up wind farms in the North Sea.
- Hydrogen power stations will emit no carbon dioxide.
- Carbon dioxide from all gas-fired stations will be captured.
- Some carbon dioxide will be sold on, to companies who can use it, in industries like construction, agriculture and chemical manufacture.
- The remaining carbon dioxide will be stored in depleted gas fields.
As technology improves, more carbon dioxide will be used rather than stored.
Other Power Sources In The Humberside Area
In the next few sub-sections, I will list the other major power sources in the Humberside area.
Drax Power Station
Drax power station is a shadow of its former self, when it was one of the power stations fed by the newly discovered Selby coalfield.
These days it is a 2,595 MW biomass-fired power station.
Eastern Green Link 2
Eastern Green Link 2 will be a 2 GW interconnector between Peterhead in Scotland and Drax.
It is shown in this map.
Note.
- Most of the route is underwater.
- It is funded by National Grid.
- Contracts have been signed, as I talk about in Contracts Signed For Eastern Green Link 2 Cable And Converter Stations.
- It is scheduled to be completed by 2029.
This interconnector will bring up to 2 GW of Scottish wind-generated electricity to Drax and Humberside.
Drax has the substations and other electrical gubbins to distribute the electricity efficiently to where it is needed.
2 GW could also reduce the amount of biomass used at Drax.
In the long term, if the concept of the four Eastern Green Links is successful, I could see another Eastern Green Link to Drax to replace imported biomass at Drax.
I also, don’t see why a smaller Drax can’t be run on locally-sourced biomass.
Solar Farms And Batteries Along The River Trent
As the coal-fired power stations along the River Trent are demolished, solar farm developers have moved in to develop large solar farms.
Salt End Power Station And Chemical Works
These two paragraphs from the Wikipedia entry for Salt End describes the hamlet and its power station and chemical works.
Salt End or Saltend is a hamlet in the East Riding of Yorkshire, England, in an area known as Holderness. It is situated on the north bank of the Humber Estuary just outside the Hull eastern boundary on the A1033 road. It forms part of the civil parish of Preston.
Salt End is dominated by a chemical park owned by PX group, and a gas-fired power station owned by Triton Power. Chemicals produced at Salt End include acetic acid, acetic anhydride, ammonia, bio-butanol, bio-ethanol, ethyl acetate (ETAC) and ethylene-vinyl alcohol copolymer (EVOH) with animal feed also being produced on site.
I wonder, if running the complex on hydrogen would give cost and marketing advantages.
Aldbrough Hydrogen Storage Facility
This page on the SSE Thermal web site is entitled Plans For World-Leading Hydrogen Storage Facility At Aldbrough.
This is the most significant paragraph of the page, that is definitely a must-read.
With an initial expected capacity of at least 320GWh, Aldbrough Hydrogen Storage would be significantly larger than any hydrogen storage facility in operation in the world today. The Aldbrough site is ideally located to store the low-carbon hydrogen set to be produced and used in the Humber region.
This is a hydrogen storage facility for a much wider area than Humberside.
Rough Gas Storage Facility
This is the first paragraph of the Wikipedia entry for the Rough Gas Storage Facility.
Rough is a natural gas storage facility under the North Sea off the east coast of England. It is capable of storing 100 billion cubic feet of gas, nearly double the storage capacities in operation in Great Britain in 2021.
In Wood To Optimise Hydrogen Storage For Centrica’s Rough Field, I describe Centrica’s plans to convert the Rough gas storage into a massive hydrogen storage.
The Location Of Aldbrough Gas Storage, Rough Gas Storage, Salt End And Easington Gas Terminal
This Google Map shows between Salt End and the coast.
Note.
- The river crossing the South-West corner of the map is the Humber.
- Salt End with its power station and chemical works is on the North Bank of the Humber, where the river leaves the map.
- Aldbrough Gas Storage is marked by the red arrow at the top of the map.
- Easington Gas Terminal is in the South-East corner of the map.
- According to Wikipedia, gas flows into and out of the Rough Gas Storage are managed from Easington.
Looking at the map, I feel that the following should be possible.
- The two gas storage sites could be run together.
- Salt End power station and the related chemical works could run on hydrogen.
- Salt End will always have a reliable source of hydrogen.
- This hydrogen could be green if required.
All the chemical works at Salt End, could be run on a zero-carbon basis. Would this mean premium product prices? Just like organic does?
Enter The Germans
The Germans have a huge decarbonisation problem, with all their coal-fired power stations and other industry.
Three massive projects will convert much of the country and industry to hydrogen.
- H2ercules, which is a project of OGE and RWE, will create a hydrogen network to bring hydrogen, to where it is needed.
- In Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal, I describe how Uniper are going to build a hydrogen import terminal at Wilhelmshaven.
- AquaVentus is an RWE project that will use 10.3 GW of offshore wind power in German territorial waters to create a million tonnes per year of green hydrogen.
These would appear to be three of Europe’s largest hydrogen projects, that few have ever heard of.
AquaVentus And The UK
This video shows the structure of AquaVentus.
I clipped this map from the video.
Note.
- The thick white line running North-West/South-East is the spine of AquaVentus, that delivers hydrogen to Germany.
- There is a link to Denmark.
- There appears to be an undeveloped link to Norway.
- There appears to be an undeveloped link to Peterhead in Scotland.
- There appears to be a link to just North of the Humber in England.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?
In the last century, the oil industry, built a substantial oil and gas network in the North Sea.
It appears now the Germans are leading the building of a substantial hydrogen network in the North Sea.
These are my thoughts about development of the AquaVentus network.
Hydrogen Production And AquaVentus
This RWE graphic shows the layout of the wind farms feeding AquaVentus.
Note.
- There is a total of 10.3 GW.
- Is one of the 2 GW web sites on the UK-side of AquaVentus, the 3 GW Dogger Bank South wind farm, which is being developed by RWE?
- Is the 0.3 GW wind farm, RWE’s Norfolk wind farm cluster, which is also being developed by RWE?
Connecting wind farms using hydrogen pipelines to Europe, must surely mitigate the pylon opposition problem from Nimbys in the East of England.
As the AquaVentus spine pipeline could eventually connect to Peterhead, there will be other opportunities to add more hydrogen to AquaVentus.
Hydrogen Storage And AquaVentus
For AquaVentus to work efficiently and supply a large continuous flow of hydrogen to all users, there would need to be storage built into the system.
As AquaVentus is around 200 kilometres in length and natural gas pipelines can be up to 150 centimetres in diameter, don’t underestimate how much hydrogen can be stored in the pipeline system itself.
This page on the Uniper web site is entitled Green Wilhelmshaven: To New Horizons.
This is a sentence on the page.
Access to local hydrogen underground storage at the Etzel salt cavern site.
An Internet search gives the information, that Etzel gas storage could be developed to hold 1 TWh of hydrogen.
That would be enough hydrogen to supply 10 GW for a hundred hours.
Note that the UK branch of AquaVentus reaches the UK, just to the South of the massive hydrogen storage facilities at Aldbrough and Rough.
It would appear that both Germany and the UK are connected to AquaVentus through substantial storage.
I am certain, that all country connections to AquaVentus will have substantial storage at the country’s hydrogen terminal.
AquaDuctus
This would appear to be the first part of the AquaVentus network and has its own web site.
The web site is entitled Nucleus Of A Offshore Hydrogen Backbone.
These are the first two paragraphs.
The project partners are focusing on a scalable, demand-driven infrastructure: By 2030, AquaDuctus will connect the first large hydrogen wind farm site, SEN-1, with a generation capacity of approximately one gigawatt. SEN-1 is located in the German EEZ in the northwest of Helgoland. The pipeline will transport at a length of approx. 200 km green hydrogen produced from offshore wind to the German mainland and from there to European consumers via the onshore hydrogen infrastructure.
In the next project stage, AquaDuctus will be extended to the remote areas of the German exclusive economic zone towards the tip of the so-called duck’s bill. By that, additional future hydrogen wind farm sites will be connected. Along its way AquaDuctus will provide interconnection points with the opportunity for linking of adjacent national offshore hydrogen infrastructures originating from Denmark, Norway, the Netherlands, Belgium and United Kingdom which opens the door for Europe-wide offshore hydrogen transport by pipeline.
There is also an interactive map, that gives more details.
This paragraph explains, why the Germans have chosen to bring the energy ashore using hydrogen, rather than traditional cables.
Recent studies show that offshore hydrogen production and transport via pipelines is faster, cheaper, and more environmentally friendly than onshore electrolysis with a corresponding connection of offshore wind turbines via power cables. The German federal government has also recognized this advantage and has clearly expressed its intention to promote offshore hydrogen production in the North Sea.
I suspect, that some UK offshore wind farms will use the same techniques.
Hydrogen Production For The UK
Electrolysers will probably be built along the East Coast between Peterhead and Humberside and these will feed hydrogen into the network.
- Some electrolysers will be offshore and others onshore.
- Turning off windfarms will become a thing of the past, as all surplus electricity will be used to make hydrogen for the UK or export to Europe.
- Until needed the hydrogen will be stored in Albrough and Rough.
Backup for wind farms, will be provided using hydrogen-fired power stations like Keadby Hydrogen power station.
Financial Implications
I reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract
This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.
These are three paragraphs from the speech.
We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.
Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.
Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.
I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.
He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.
If we are exporting electricity and hydrogen to Europe, this is likely to have three effects.
- An improvement in Europe’s energy security.
- H2ercules will improve and decarbonise German industry, using UK hydrogen.
- The finances of UK plc will improve.
It looks like there would be winners all round.
Rishi Sunak had the cards and he played them very badly.
It is now up to Keir Starmer, Great British Energy and Jürgen Maier to play those cards to link the energy systems of the UK and Germany to ensure security and prosperity for Europe.
Rolls-Royce To Be A Partner In Zero-Carbon Gas-Fired Power Station In Rhodesia
This press release from Rolls-Royce is entitled Rolls-Royce, Landmark And ASCO Collaborate On CO2 Recovery Power Generation Solutions.
These three bullet points serve as sub-headings.
- Cooperation plans to develop solutions for clean power generation with carbon capture from gas reciprocating engines
- Captured CO2 will be available for use in industries such as food, Efuels, sustainable aviation fuels (SAF), cement and plastic production
- First of-its-kind flexible power generation and carbon capture plant currently under construction in Nottinghamshire, UK
This image shows a Rolls-Royce mtu Series 4000 gas genset.
Note.
- Power is up to 2.5 MW.
- The engine is labelled H2-ready on its web page.
These two paragraphs add some detail to the project.
Rolls-Royce, ASCO Carbon Dioxide Ltd (ASCO), and Landmark Power Holdings Limited (LMPH), have signed a Memorandum of Understanding (MoU) aimed at developing scalable solutions for clean power generation with carbon capture from mtu gas reciprocating engines. This strategic partnership will help enable power generation customers to achieve their net zero ambitions and marks a significant step towards addressing climate change.
“Power generation is a highly attractive, growing market segment and an area of strategic focus for Rolls-Royce, where partnerships can help further grow market position and broaden its power generation offering, as set out at last November’s Capital Markets Day”, said Tobias Ostermaier, President Stationary Power Solutions at Rolls-Royce Power Systems. Rolls-Royce is committed to becoming a net zero company by 2050 and supporting customers to do the same.
These are my thoughts.
Uses Of Carbon Dioxide
The press release from Rolls-Royce lists a few uses of carbon dioxide.
The plan is to make the captured CO2 available (utilisation) for use in various industries such as food production, Efuels, sustainable aviation fuel (SAF), cement and plastic production (utilisation). The captured CO2 will also be ready for transportation should permanent sequestration be preferred (storage).
Carbon dioxide can also be added to the air in greenhouses, that are producing flowers, herbs, salad vegetables, soft fruit and tomatoes.
ASCO Carbon Dioxide
ASCO Carbon Dioxide is a subsidiary of French company; Schneider Electric.
The home page on their web site, describes ASCO Carbon Dioxide like this.
The Swiss ASCO CARBON DIOXIDE LTD is a globally operating company that offers complete solutions for CO2 and dry ice. The range of services includes carbon capture plants, CO2 recovery systems, ASCOJET dry ice blasting machines, dry ice production machines, CO2 cylinder filling systems, CO2 vaporisers, CO2 storage tanks, CO2 dosing systems for water neutralization and various other CO2 and dry ice equipment.
Thanks to this broad product range and more than 130 years of practical experience in the comprehensive CO2 and dry ice sector, the customer benefits from individual, complete CO2 solutions from a single source. ASCO has been part of the international industrial gases company Messer Group since 2007 and is its centre of competence for CO2.
In other words, the world and especially the climate change activists may hate carbon dioxide with a vengeance, but ASCO Carbon Dioxide see it as a way to make money and something that needs love.
It also seems, that if you want to do something with or to carbon dioxide, then ASCO Carbon Dioxide could be one of the first companies that you call.
Landmark Power Holdings Limited
The About page on their web site, describes the mission of Landmark Power Holdings Limited like this.
LMPH was established in 2019 with the purpose to help to build a circular economy, by applying new methodologies to proven technologies in energy production.
We support the transition to net zero by supplying dispatchable, low carbon energy that enables more renewable energy production while contributing to a circular economy, by eliminating inefficiencies in production, ensuring that every input is used to its maximum potential and treating all production waste as a profitable resource.
This Solutions page on their web site, describes their FlexPower Plus system.
These are the two introductory paragraphs.
FLEXPOWER PLUS® is LMPH’s modular approach to optimising the generation of clean flexible power. It is a combination of High Efficiency Flexible Power Generation modules and Carbon Capture Utilisation (CCU) modules.
Each of the modules can be added to the production processes depending on the site and production needs.
This last paragraph describes the result.
When you combine the the High Efficiency Flexible Power Generation modules with the Carbon Capture Utilisation (CCU) modules, the power generation is classified as low carbon and considered to be as clean as wind power but with the capacity to provide baseload power.
They certainly sound like my kind of company, as I was simulating processes like this for ICI in the 1970s.
ICI taught me that only four things should leave a chemical or other process plant.
- Product, that is sold at an advantageous price.
- Pure water
- Clean air
- Everybody who worked there.
It appears a FlexPower Plus system produces three valuable products; electricity, heat and pure food-grade carbon-dioxide.
The Rhodesia Project
The Rhodesia project has its own page on the Landmark Power Holdings web site, where these four paragraphs describe the project.
The Rhodesia project is a joint venture with Victory Hill, a specialist investment firm targeting direct investments in global energy infrastructure that support the UN Sustainable Development Goals.
The Rhodesia project is located in north Nottinghamshire near Worksop and has an electrical capacity of 10MW.
Additional capacity is to be sold through a private wire power supply for local businesses with the intent to facilitate vehicle charging stations.
Construction started in March 2022 and the start of power production is projected for Q3 2024 with the full CO2 capture from Q4 2024.
There is also this paragraph, that lists the partners in the Rhodesia project.
For the development of the Rhodesia project LMPH and Victory Hill have partnered with global industrial groups such as Mitsubishi Turboden S.p.A., MTU Rolls-Royce Solutions UK, ASCO CARBON DIOXIDE LTD, Climeon.
With three of the world’s largest companies amongst the partners, this partnership must have a high chance of success.
Victory Hill Capital Hill Partners
Victory Hill Capital Partners are partners in the Rhodesia project.
Their joint philosophy with Landmark Power Holdings is summed up on this video.
Working Together
The press release from Rolls-Royce says this about the partnership.
Rolls-Royce is contributing its extensive experience and global network in the field of decentralized power generation to the cooperation through its Power Systems division with the mtu product portfolio. The contribution of LMPH, a developer of high-efficiency Combined Heat and Power (CHP) projects, is its patented FLEXPOWER PLUS® concept, combined with technical expertise and patented technologies. ASCO has over 50 years of experience in developing and building carbon capture (or CO2-Recovery) plants and will be providing valuable insights and solutions from the carbon capture industry.
There is also this diagram of the system.
Note.
- The 4000 gas genset is in the bottom-left corner.
- The HT PRC and LT ORC are two Mitsubishi turbo-generators generating electricity from waste heat.
- The ASCO carbon capture system is in the top-left corner.
- Carbon dioxide can either be stored or used.
This system should be zero-carbon, once the design is fully tested.
A View From The Top
This paragraph from the Rolls-Royce press release gives the view of the President Stationary Power Solutions at Rolls-Royce Power Systems.
Tobias Ostermaier, President Stationary Power Solutions at Rolls-Royce Power Systems, said: “We are convinced that CO2 capture and storage systems in combination with our mtu gas gensets are an important building block on the way to Net Zero. As a complement to renewable energy sources, internal combustion engines can already provide clean, cost-effective and extremely reliable power generation.”
I suspect he’s rather pleased.
UK Energy Grid Needs £60bn Upgrade To Hit Green Target, Plan Says
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The UK’s electricity network needs almost a further £60bn of upgrades to hit government decarbonisation targets by 2035, according to a new plan.
These five paragraphs explain the plan.
About 4,000 miles of undersea cables and 1,000 miles of onshore power lines are needed, said the National Grid’s Electricity Systems Operator (ESO).
The investment would add between £20 to £30 a year to customer bills, it said.
The government said the ESO’s plans were preliminary and yet to pass a “robust planning process”.
The plans were written up by the ESO, the organisation which runs the electricity network and would run the updated system it is calling for too. It is currently owned by National Grid but will transfer into government ownership later this year.
Its latest £58bn estimate is for work needed between 2030 and 2035 and comes on top of a previous £54bn estimate for work taking place between now and 2030.
These are my thoughts.
The Amount Of Undersea Cable
Edinburgh and London are roughly 400 miles apart as the train runs, so it looks like there could be the equivalent of ten underwater cables between the North of Scotland and England.
In Contracts Signed For Eastern Green Link 2 Cable And Converter Stations, I talked about the proposed 2 GW link between Peterhead in Scotland and Drax in England, which will be a double cable. So there’s the first two of these long cables.
It looks to me, that National Grid are proposing to use underwater cables wherever they can, so they avoid large expensive planning rows stirred up by Nimbies.
Monitoring The Undersea Cables
Last week Ofgem gave National Grid a £400,000 grant to develop new innovative technologies, which I wrote about in £400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition.
One of the project is called HIRE – Hybrid-Network Improvement & Reliability Enhancement and will be used to check all these cables are performing as they should.
My electrical engineering experience tells me, that there must be some cunning way, that will detect that something is happening to the cable. The involvement of a technology company called Monitra in the project is a bit of a giveaway.
How Much Will It Cost Me?
Currently, UK consumers pay about £30 per year to have electricity delivered, so this will rise to between £50 and £60 per year.
That is just over a pound a week. I would pay about the same for a resident’s parking permit outside my house for an electric car and probably three times more for a petrol or diesel car.
Do We Have Enough Cable?
Two undersea cable factories are under development in Scotland and I suspect the 4,000 miles of undersea cables will be delivered on schedule and covered in saltires.
What About T-Pylons?
The latest onshore electricity transmission line between Hinckley Point C and Bristol, doesn’t use traditional pylons.
It uses T-pylons like these to connect the 3.26 GW nuclear power station.
Note that they are shorter, designed to be less intrusive, have a smaller footprint and are made from only ten parts.
I suspect they will cost less to install and maintain.
There is more on T-pylons in National Grid Energise World’s First T-Pylons.
I wouldn’t be surprised that some of the oldest traditional pylons will be replaced by T-pylons.
I am surprised that T-pylons are not mentioned in the BBC article.
I like T-pylons. How do you feel about them?
Eastern Green Link 2
This press release from National Grid, describes Eastern Green Link 2 like this.
Eastern Green Link 2 (EGL2) is a 525kV, 2GW high voltage direct current (HVDC) subsea transmission cable from Peterhead in Scotland to Drax in England delivered as a joint venture by National Grid and SSEN Transmission.
This map from National Grid, shows the route of the Eastern Green Link 2.
The Northern landfall is at Sandford Bay and the Southern landfall is at Wilsthorpe Beach.
This Google Map shows Sandford Bay and Peterhead power station.
Note.
- Sandford Bay occupies the North-East corner of the map.
- The red arrow indicates the main 400kV sub-station at Peterhead.
- The 2177 MW gas-fired Peterhead power station is to the East of the sub-station marked as SSE.
This second Google Map shows the onshore route of the cable from Wilsthorpe to Drax.
Note.
- Flamborough Head is in the North-East corner of the map.
- Wilsthorpe Beach is at Bridlington a couple of miles South of Flamborough Head.
- The red arrow indicates Drax Power station.
- An onshore underground cable will be installed from landfall in Wilsthorpe to a new onshore converter station built in Drax.
The EGL2 HVDC cable connection from Scotland to England consists of 436km of submarine cable and 69km of onshore cable.
Both converter stations will be on existing power station sites and the major onshore works will be the underground cable between Wilsthorpe and Drax.
Where Does Drax Go From Here?
Currently, Drax power station is a 2595 MW biomass-fired power station.
There are now other large power sources that could replace some or all of the output of Drax power station.
- 2GW of Scottish wind power coming to Drax on Eastern Green Link 2.
- 6 GW of offshore wind is being developed at the Hornsea wind farms.
- 8 GW of offshore wind is being developed at the Dogger Bank wind farms.
- 2.5 GW from the three gas-fired power stations at Keadby, two of which are likely to be fitted with carbon capture.
- 1.8 GW from the proposed hydrogen-fired Keadby Hydrogen power station.
Given the bad feelings many have about Drax burning biomass, with 20.3 GW of electricity, you might think that shutting down Drax would be a simple solution.
But, according to Drax’s Wikipedia entry, it has a unique property.
Despite this intent for baseload operation, it was designed with a reasonable ability for load-following, being able to ramp up or down by 5% of full power per minute within the range of 50–100% of full power.
So Drax could be very useful in balancing the grid, by ramping up and down to fill the gap between production and need.
In addition, there is good biomass. This is from the Wikipedia entry.
A 100,000 tonne pa capacity straw pelletization facility was constructed at Capitol Park, Goole in 2008.
Drax are also promoting BECCS or Bioenergy carbon-capture and storage.
There is a Wikipedia entry for Bioenergy With Carbon Capture And Storage, of which this is the first couple of sentences.
Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon, thereby removing it from the atmosphere. BECCS can theoretically be a “negative emissions technology” (NET).
I do feel that carbon capture and storage is a bit like sweeping the dust under the carpet, when you sweep the floor around it.
But carbon capture and use could be another matter.
This Google Map shows the Drax site.
Note how it is surrounded by agricultural land.
Could the power station be the source of pure carbon dioxide to be fed in greenhouses to flowers, herbs, salad vegetables, tomatoes and other plants?
I suspect there’s productive life left in Drax power station yet!
LionLink
LionLink, that is being developed by National Grid is a new type of interconnector, called a multi-purpose interconnector, that will connect Suffolk and The Netherlands via any convenient wind farms on the way. This means that the electricity generated can go where it is needed most.
I wrote about LionLink in World’s Largest-Of-Its-Kind Power Line To Deliver Clean Power To 1.8m UK Homes And Boost Energy Security.
Other Multi-Purpose Interconnectors
I can see other multi-purpose interconnectors like LionLink being built around the UK.
- There could be one across the Dogger Bank to link out 8 GW of Dogger Bank wind farms with those of the Dutch, Danes and Germans on their section of the bank.
- NorthConnect could be built between Scotland and Norway via some of the wind farms being developed to the North-East of Scotland.
- Could wind farms to the North of Ireland use a multi-purpose interconnector between Scotland and Northern Ireland.
- I can also see one or possibly two, being built across the Celtic Sea to link Devon, South Wales and Southern Ireland via the wind farms being developed in the area.
- Will we also see a Channel multi-purpose interconnector to transfer electricity along the South Coast of England?
Some of these multi-purpose interconnectors could be key to creating a revenue stream, by exporting electricity, to countries in Europe, that have a pressing need for it.
Conclusion
National Grid’s excellent plan will lead to the end of the practice of shutting down wind turbines. The spare electricity will be exported to Europe, which will surely create a good cash-flow for the UK. This in turn will encourage developers to create more wind farms in the seas around the UK’s coasts.
Google Starts Building £790m Site In Hertfordshire
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Google has invested $1bn (£790m) to build its first UK data centre
These are the first four paragraphs.
The tech giant said construction had started at a 33-acre site in Waltham Cross, Hertfordshire, and hoped it would be completed by 2025.
Google stressed it was too early to say how many jobs would be created but it would need engineers, project managers, data centre technicians, electricians, catering and security personnel.
The prime minister said it showed the UK had “huge potential for growth”.
The project marked the latest investment by a major US tech firm in Britain, after Microsoft announced it would invest £2.5bn to expand data centres for artificial intelligence (AI) across the UK.
Note.
- By “completed by 2025” do they mean completed before 2025 or completed by the end of 2025. Judging by the time they took to build their London HQ, its the latter.
- Rishi is right about the UK having a huge potential for growth! Especially, if the nihilists of the United States vote in the Big Orange!
- Judging by the total spend of £2.5 billion on data centres and the £790 million for this one, this looks to be the first of three.
But where is this data centre going to be built?
This article on EssexLive is entitled Google To Move Into Waltham Cross With £788m Data Centre To Support ‘AI Innovation’, where this is said.
The new data centre will go on land at Maxwell’s Farm, next to the A10 Great Cambridge Road and around one mile from the M25 junction 25. Debbie Weinstein, Google vice president and managing director in the UK and Ireland, set out the decision in a blog post on Thursday, January 18 – the fourth day of the World Economic Forum’s Davos 2024 in Switzerland.
This is a Goggle Map of that area, when I searched for Maxwell’s Farm.
Note.
- The red arrow indicates the result of my search, which Google interpreted as A.J. Maxwell.
- The dual-carriageway road running down the East side of the map is the A10 between London and Cambridge.
- The A10 road joins the M25 at Junction 25.
- The arrow to the South-West of the roundabout indicates the new studios; Sunset Waltham Cross, which is being built.
- At the other side of the studio site, there is a label saying New River and this important piece of London’s water infrastructure can be traced to the top of the map.
- The other dual-carriageway road is the B198 or Lieutenant Ellis Way.
- A quick calculation shows that 33 acres is roughly a 365 metre square.
I would suspect that the data centre will lie somewhere between the A10, the B198 and the New River.
This Google Map shows the South-East corner of the site.
Note.
- There appears to be a lane running East-West, that crosses over both the A10 and the New River.
- Theobalds Lane appears to have some housing and possibly a farm.
- The smaller field by the roundabout appears to have some animals using it as grazing.
- The field between the East-West lane and Theobalds Lane appears to have a good crop of cereal.
The East-West lane would appear to be a possible Southern border of the site.
This Google Map shows where the East-West lane goes.
Note.
- The lane leads to Queen Mary’s High School.
- The school also has access from Lieutenant Ellis Way.
- The New River appears to form, the Eastern boundary of the school site.
- There are sports pitches between the New River and the school.
The New River looks to be the Western boundary of the Google site.
This Google Map shows around the red arrow from the Google search that led me to this area.
Note.
- A.J. Maxwell is identified by the red arrow in the Theobalds Enterprise Centre.
- The New River can be seen at the West of the map.
- A hedge runs roughly East-West to the North of the Enterprise Centre.
- North of the hedge are a number of football pitches, which appear to belong to the Affinity Academy at Goffs Churchgate.
The hedge could be the Northern boundary of the Google site.
This Google Map shows the area between the South of the Enterprise Centre and the East-West lane I picked out earlier.
A crude measurement indicates it could be around 33 acres or slightly more.
This picture is used in nearly all the news reports about the Data Centre.
Note.
- Could that be the gentle curve of the New River on the left?
- With the high fence, the New River forms an almost-mediaeval defence against trespassers.
- There looks to be a dual-carriageway road running down the other side of the site, which would be the A10.
- Between the A10 and the site, there appears to be loots of dark areas, which I take to be car parks.
- Are the car-parking spaces in the front of the picture marked for those, who are disabled? There certainly appear to be chargers on some spaces.
I have a few thoughts.
The Relative Locations Of Google’s Data Centre And Sunset Studios?
This Google Map shows the two sites to the West of the A10.
Note.
- St. Mary’s High School is in the North-West corner of the map.
- Cheshunt Football Club is in the North-East corner of the map.
- The dual-carriageway A10 runs North-South on the map.
- I believe that Google’s Waltham Cross Data Centre will be located in the field to the West of the A10, at the top of the map.
- The A10 connects to the M25 at Junction 25, which is in the centre at the bottom of the map.
- In The Location Of Sunset Studios In Broxbourne, Sunset Studios are placed to the North West of the Junction 25 roundabout.
- Just as the A10 forms the Eastern boundary of both sites, the New River forms the Western boundary.
The two sites are close together between the A10 and the New River, separated by the dual-carriageway Lieutenant Ellis Way.
Will Google’s Data Centre Be Storing Data For Sunset Studios?
I’ve never worked in the production of films, but these days with digital electronic cameras, CGI, motion capture and other techniques, producing a film must need huge amounts of data storage.
- So have Sunset Studios outsourced their data storage needs to Google?
- Perhaps too, Sunset Studios found the local authority welcoming and this attitude was recommended to Google.
- Both sites will need local services like electricity, gas, sewage and water.
I suspect that there would be cost savings in construction and operation, if the two sites shared the utilities.
Providing Electricity And Heat For Both Sites
Consider.
- I estimate from information given in the Wikipedia entry for Google Data Centres, that a data centre needs between 10 and 12 MW.
- There is no obvious power source like offshore wind or a nuclear power station nearby.
- There is the 715 MW Rye House gas-fired power station, which is a few miles away.
- In Google Buys Scottish Offshore Wind Power, I talked about how Google had signed a Corporate Power Purchase Agreement to buy 100 MW from the Moray West offshore wind farm.
Google and Sunset Studios would also want an electrical and heat supply that is at least 100 % reliable.
Liverpool University had the same problem on their hundred acre campus in the centre of Liverpool.
- The University decided to build their own 4 MW Combined Heat and Power Unit (CHP), which is described in this data sheet.
- It is fired by natural gas.
- On their web site, Liverpool University state that their CHP can be adapted to different fuel blends. I take this includes zero-carbon fuels like hydrogen and carbon-neutral fuels like biomethane.
But given their location in Waltham Cross close to the Lea Valley, CHP units may have a use for their carbon dioxide.
This Google Map shows between Junction 15 of the M25 and Tomworld.
Note.
- Junction 25 of the M25, where it joins the A10 is in the South-West corner of the map.
- The sites of Google’s Data Centre and Sunset Studios can be picked out with reference to the previous map.
- Tomworld is in the North-East corner of the map.
- So why should Tomworld need a lot of carbon-dioxide?
This Google Map shows Tomworld.
Note.
- This web page indicates what Tomworld do.
- They have 44 acres of glass growing tomatoes, about five miles to the North-East of Google’s Data Centre.
- The map has lots of other greenhouses.
I know of a guy, who has a large greenhouse, that grows tomatoes for the supermarkets.
- He heats the greenhouse with a gas-fired Combined Heat and Power Unit (CHP).
- The electricity produced runs his business.
- Any surplus electricity is fed into the grid.
- The carbon dioxide is fed to the plants in the greenhouse, which helps them grow quality tomatoes.
I just wonder, if carbon dioxide from CHP units at Google’s Data Centre and Sunset Studios could be used by the multitude of greenhouses in the Lea Valley.
Could A Carbon Dioxide Pipeline Be Built Along The M25?
This Google Map shows the Northern section of the M25, South of Waltham Cross.
Note.
- The M25 running East-West across the bottom of the map.
- Junction 25 of the M25 in the South-West corner of the map.
- The A10 running North-South at the West of the map.
- Google’s data centre and Sunset Studio are to the West of the A10.
- The River Lee, which has numerous water courses is at the East of the map.
I wonder, if a carbon dioxide pipeline could be built along the M25 to connect the producers to those who could use it?
- It would not be a dangerous pipeline as carbon dioxide is a fire extinguisher.
- It wouldn’t be a huge pipe.
I think it would be possible.
Google’s Commitment To Being Zero-Carbon
This blog post on the Google web site is entitled Our $1 Billion Investment In A New UK Data Centre, has a section, which has a sub-title of 24/7 Carbon-Free Energy By 2030, where this is a paragraph.
Additionally, we’re also exploring new and innovative ways to use the heat generated by data centres, and this new facility will also have provisions for off-site heat recovery. Off-site heat recovery presents an opportunity for energy conservation that benefits the local community, as it allows us to capture the heat generated by the data centre so that it can be used by nearby homes and businesses. The data centre is also set to deploy an air-based cooling system.
If they are using off-site heat recovery, it would be logical to use waste carbon dioxide from CHPs to provide carbon dioxide for the local horticultural businesses.
Will Google Be Building A Vertical Farm Nearby?
In Schneider Electric: Vertical Farming – The Next Yield In Data Centre Sustainability, I noted that some data centres are paired with vertical farms to increase their sustainability.
Could Google be doing that in Waltham Cross?
- They will have a lot of waste heat.
- They will have a fair bit of carbon dioxide, which could be used to help plants grow.
- The local workforce probably contains a lot of experience of market gardening.
I like the idea of pairing a data centre and a vertical farm.
Public Transport Access
Consider.
- Increasingly, the cost of electric vehicles, medical problems and the UK economic situation are causing people to adopt a car-free lifestyle.
- After my stroke, my eyesight deteriorated such, that I am no longer allowed to drive.
- Others may live in one-car families and it may not be their’s to use every day.
- Or your car may just break down on the way to work.
For these and probably lots of other reasons, any large site employing a lot of employees, must have a valid way of getting there by public transport.
The nearest rail station to Google’s Data Centre and Sunset Studios is Theobalds Grove station.
This Google Map shows the roads between the sites and the station.
Note.
- The Sunset Waltham Cross label in the South West corner.
- Google’s Data Centre will be just off the map to the West of the A10.
- Theobalds Grove station is marked by the TfL roundel in the North-East corner of the map.
- There would appear to be no bus stops on Winston Churchill Way or the A10.
I walked South from the station to Winston Churchill Way, where I took these pictures.
Note.
- At that point, I gave up because of the cold and pollution.
- It was also a Saturday morning about midday.
The route I took is certainly not an alternative route to get to Google’s Data Centre or Sunset Studios.
A Possible Station At Park Plaza North
This article on the BBC is entitled Broxbourne: Two New Stations Planned.
This is the sub-heading.
Two new train stations could be built in Hertfordshire if plans to tighten planning policies are adopted.
This is the first paragraph.
Broxbourne Borough Council said stops at Park Plaza North – between Turkey Street and Theobalds Grove London Overground stations – and Turnford on the London to Bishop’s Stortford route would be subject to a consultation.
Later the BBC say that Park Plaza North station will be South of the A121 Winston Churchill Way near Waltham Cross
This Google Map shows the area South-East of the roundabout, where Winston Churchill Way meets the A10.
Note.
- The green patch of land to the South-East of the roundabout where Winston Churchill Way meets the A10 appears to be ripe for development.
- Looking at the green patch with a higher resolution, the land is little more than high class scrub beloved of newts.
- The London Overground line to Cheshunt runs down the East side of the site.
- To the North, the London Overground crosses Winston Churchill Way to get to Theobalds Grove station.
- To the South, the London Overground crosses the M25 to get to Turkey Street station.
- There is a lane running East-West along the South edge of the site, which crosses the railway in a level crossing.
This picture clipped from Google StreetView shows the level crossing.
This is certainly one, that drivers dread.
This GoogleMap shows the level crossing and a stretch of the London Overground.
Note.
- The level crossing is in the South-East corner of the map.
- There isn’t much space to put a London-bound platform on the East side of the tracks, South of the Park Road circle.
- There is plenty of space to put a Cheshunt-bound platform on the West side of the tracks.
- North of the Park Road circle, there would appear to be space for two platforms.
It will need a lot of ingenuity to provide a safe and efficient solution to the problems of the level crossing and fitting a station in this limited space.
The first thing I’d do, would be to dig an underpass for pedestrians and cyclists to connect the two halves of Park Lane.
SSE Thermal Acquires 50% Stake In H2NorthEast Hydrogen Project
The title of this post is the same as that of this press release from SSE Thermal.
These are the first three introductory paragraphs.
SSE Thermal has become joint owner of a blue hydrogen project in Teesside which is set to play a major role in supporting a reliable decarbonised power system by 2035 and accelerating industrial decarbonisation.
The partnership with Kellas Midstream will see the companies jointly develop H2NorthEast, a hydrogen production facility with carbon capture and storage that could help to kickstart a hydrogen economy in the Tees Valley. The agreement is for an initial consideration of <£10m to Kellas Midstream with further contingent consideration due should the project reach a financial investment decision.
In its first phase, H2NorthEast could deliver up to 355MW of blue hydrogen production capacity from 2028 with plans to scale up to more than 1GW. Offtakers would include heavy industry and power generation, either through blending into existing assets or in new hydrogen-fired plants.
Note.
- Production of 355 MW of hydrogen could start in 2028.
- Several existing processes have been converted from gas-firing to hydrogen-firing or a blend of natural gas and hydrogen firing. See Lime Kiln Fuelled By Hydrogen Shown To Be Viable.
- Teesside has quite a few industries, like steel and chemicals that theoretically could be converted to hydrogen or a hydrogen blend.
I have some thoughts.
Carbon Capture And Storage
This paragraph in the press release talks about the carbon capture and storage.
With an anticipated minimum carbon capture rate of 97%, H2NorthEast meets both UK and EU low-carbon standards. Specifically, the hydrogen produced via H2NorthEast would be fully compliant with both the UK’s Low Carbon Hydrogen Standard and is expected to be aligned with the EU Taxonomy for sustainable activities.
If the plant can achieve a carbon capture rate of 97 %, that is very good and it appears to meet the required standards.
- I also feel, that if it is of a high purity, then that could be a bonus, as it could be used in food manufacturing and other processes, where high purity is needed.
- I feel SSE should endeavour to use as much of the carbon dioxide, as it can to produce valuable by-products, which could include cement substitutes, building blocks, plasterboard and animal feed.
- Carbon dioxide can also be fed to soft fruit, salad vegetables, tomatoes, flowers and other plants in giant greenhouses or vertical farms.
- Polyester yarn can also be made from carbon dioxide.
It is my belief that this list of products will grow in the next ten years and carbon dioxide of a high purity will become an important chemical feedstock.
Replacement of Blue Hydrogen With Green
If SSE Renewables were to build an electrolyser near to H2NorthEast, they could use that to replace the blue hydrogen.
- From an offtaker’s point of view green and blue hydrogen would be identical.
- It’s just that the green hydrogen doesn’t produce any carbon dioxide.
- I can see the complex being run to produce enough carbon dioxide to supply the users that need it and producing blue and/or green hydrogen accordingly.
Hopefully, the more uses that can be found for the carbon dioxide, the less of it will need to use long-term storage.
Expanding The Plant
As blue and green hydrogen plants create an identical product, the decision of whether to add an extra blue hydrogen or green hydrogen plant can be taken solely on financial grounds.
Conclusion
This looks like it could be a very sensible decision by SSE.
Flotation Energy, Vårgrønn Seal Exclusivity Agreements For 1.9 GW Scottish Floaters
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Vårgrønn, a joint venture between Plenitude (Eni) and HitecVision, and Flotation Energy have signed exclusivity agreements for two floating offshore wind developments under Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.
These two paragraphs give more details.
Once completed, the floating offshore wind farms, with up to a total of 1.9 GW capacity, will provide renewable electricity to oil and gas platforms, aiming to reduce carbon emissions from the assets they supply.
In addition, Green Volt and Cenos projects will also provide electricity to the UK grid.
Note.
I can’t see a loser with these wind farms.
- The wind farms provide zero-carbon electricity to oil and gas platforms.
- These platforms cut their emissions, by not using fossil fuels to generate the electricity they need for their operation.
- Some platforms use gas to generate the electricity, so this gas can be delivered to the shore for the UK gas network.
- Any spare electricity will be available for using in the UK electricity grid.
- Crown Estate Scotland will be paid for the lease for the wind farm.
There will be no carbon emissions from the platforms, but there will be extra onshore emissions from any gas that is currently used to power the platforms, if it is burnt onshore in power stations and industrial processes, or used for heating.
But increasingly gas in the UK will be used in applications, where the carbon emissions can be captured for use or storage.
It will be very interesting to see how as offshore operations are decarbonised our total carbon emissions change.
The Anonymous Widower
