UK CfD Round 4 Offshore Wind Projects Power Forward
The title of this post, is the same as that of this article on offshoreWIND.biz.
These are the first two paragraphs.
All 99 contracts offered through the fourth Allocation Round (AR4) of the UK government’s Contracts for Difference (CfD) scheme have now been signed and returned to Low Carbon Contracts Company (LCCC).
A total of 93 individual projects across Britain will now proceed to work with LCCC to meet the contractual milestones specified in the CfD, supporting projects’ development and the delivery of almost 11 GW of clean energy. The first AR4 projects are due to come online in 2023-24.
It does look like it’s a case of all systems go!
In Will We Run Out Of Power This Winter?, I estimated that these Round 4 projects would come onstream as follows.
- 2024 – Round 4 Solar – 125.7 MW
- 2025 – Round 4 Solar – 1958 MW
- 2025 – Round 4 Onshore Wind – 888 MW
- 2025 – Round 4 Energy from Waste – 30 MW
- 2026 – Round 4 Tidal Stream – 5.62 MW
- 2027 – Round 4 Tidal Stream – 35.2 MW
- 2027 – Round 4 Floating Offshore Wind – 32 MW
- 2027 – Round 4 Offshore Wind – 6994 MW
These are totals for the next four years from these contracts.
- 2024 – 125.7 MW
- 2025 – 2876 MW
- 2026 – 5.62 MW
- 2027 – 7061.2 MW
This is a total of over 10 GW.
Lime Kiln Fuelled By Hydrogen Shown To Be Viable
The title of this post, is the same as that of this article on the Construction Index.
Lime is one of those materials that plays a large part in our lives without our even knowing it. The Wikipedia entry lists a multitude of uses.
The article starts with these paragraphs.
The trial, led by Tarmac at its Tunstead site near Buxton, was the culmination of a project to demonstrate the potential to use hydrogen as a viable fuel alternative to natural gas for commercial-scale production of lime.
A number of trials were conducted with differing energy replacements, which culminated in a 100% replacement of the natural gas.
While it has been shown to be feasible, we have not yet been told how soon it might be practical or affordable.
The article finishes with this optimistic statement.
Tarmac, a CRH company, has cut CO2 by 24% per tonne of product since 1990; it is aiming for 45% by 2030.
This article illustrates how some important industries create a lot of carbon emissions and how decarbonisation would be fairly easy with a plentiful supply of hydrogen.
This is also the sort of industry, that would benefit from blending up to twenty percent of hydrogen into the UK’s natural gas supply, as is currently being investigated by the HyDeploy project.
SSE Issues €650M Green Bond As It Ramps Up Net Zero Acceleration Programme
The title of this post, is the same as that of this press release from SSE.
This is the first two paragraphs.
SSE plc has successfully issued a €650m 7-year green bond maturing 1 August 2029 at a coupon of 2.875 per cent.
Today’s issuance is SSE’s fifth green bond in six years and reaffirms its status as the largest issuer of green bonds from the UK corporate sector. It remains the only UK corporate to offer up multiple green bonds and this latest issuance brings SSE’s total outstanding green bonds to over £2.5bn.
It’s good to see that a company can raise money by issuing bonds to finance its green ambitions.
A few years ago, green investments were derided by many, but it now seems that SSE have made hem mainstream.
Rolls-Royce To Play Key Role In US Department Of Defense Nuclear Microreactor Program
The title of this post, is the same as that of this press release from Rolls-Royce.
This paragraph outlines the program.
Rolls-Royce has been an industry leader in developing reliable sources of energy to help the Department of Defense and other customers be resilient using various energy sources. We pioneer cutting-edge technologies that deliver clean, safe and competitive solutions. We are excited to be part of the winning BWXT team along with Northrop Grumman, Aerojet Rocketdyne and Torch Technologies, and expand our capabilities in nuclear power generation.
There is also a link to this web press release on the BWXT web site, which is entitled BWXT to Build First Advanced Microreactor in United States.
This is the first paragraph.
BWX Technologies, Inc. (NYSE: BWXT) will build the first advanced nuclear microreactor in the United States under a contract awarded by the U.S. Department of Defense (DoD) Strategic Capabilities Office (SCO). The Project Pele full-scale transportable microreactor prototype will be completed and delivered in 2024 for testing at the Idaho National Laboratory.
These three paragraphs outline the design.
The high-temperature gas-cooled reactor (HTGR) will operate at a power level between 1 and 5 MWe and will be transportable in commercially available shipping containers. It will be powered by TRISO fuel, a specific design of high-assay low-enriched uranium (HALEU) fuel that can withstand extreme heat and has very low environmental risks.
The transportable reactor core and associated control system is designed to maintain safety under all conditions, including transitional conditions throughout transport. The fuel has been tested and verified to temperatures far exceeding the operating conditions of the reactor.
The transportable design consists of multiple modules that contain the microreactor’s components in 20-foot long, ISO-compliant CONEX shipping containers. The reactor is designed to be safely and rapidly moved by road, rail, sea or air. The entire reactor system is designed to be assembled on-site and operational within 72 hours. Shut down, cool down, disconnection and removal for transport is designed to occur in less than seven days.
Note.
- This Wikipedia entry describes the HTGR.
- One of the advantages of the HTGR is that it can be built in relatively small unit sizes.
- These reactors can also produce heat as well as electricity.
- Some designs of HTGR use both nuclear and gas-turbine technology.
The last paragraph of the specification, sounds to be particularly challenging.
There is also an Anglo-Dutch design from the Universities of Manchester and Delft, which is called a U-battery.
- Their flyer is particularly informative.
- Two of their supporters are BWXT and Rolls-Royce.
Do the two projects share technology?
Is The Morocco-UK Power Project Just A Taste Of The Future?
After writing WSP Lends Hand On Morocco-UK Power Link, about WSP’s involvement in the ambitious project to create a 3.6 GW interconnector to bring power from Morocco to the UK, I’m now certain, that this major project will come to fruition.
Out of curiosity, I created this Google Map of North-West Africa.
Note.
- Morocco is at the North edge of the map.
- The map is filled with the Sahara Desert.
- The Caqnary Islands are off the coast of Africa.
- Three of the least developed countries in the world; Western Sahara, Mauritania and Mali, circle the desert to the South-West and South.
I do wonder if the Morocco-UK Power Project is a success, if other developers and countries will decide to developer their renewable energy resources.
- France, Portugal and Spain may want to get involved.
- High-Temperature Electrolysis boosted by solar energy, could be used to generate hydrogen for shipment to Europe.
- The interconnectors to Europe will be upgraded.
Given the size of the desert, I’m sure that several GW of electricity could be delivered to Europe.
WSP Lends Hand On Morocco-UK Power Link
The title of this post, is the same as that of this article on renews.biz.
These introductory paragraphs detail WSP’s role.
Xlinks has appointed engineering consultancy WSP to provide technical advisory services for the tendering process for converter stations for its Morocco-UK power link.
WSP will support the procurement process for four HVDC converter stations in the UK and also Morocco, as well as UK grid connection works, connection to the generation assets in Morocco, and an interface between the converter stations and the HVDC cable systems in the UK and Morocco.
When I wrote my first post on this project in September 2021, which was entitled Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project, I was a bit sceptical that this project would be completed.
With the appointment of WSP, I am now very much happier that this project will be carried through to a successful conclusion.
BP To Charge Up Vehicle Battery Research
The title of this post is the same as that of this article in The Times.
This is the title on a stock picture at the top of the page.
BP, whose profits benefited from soaring oil and gas prices, plans to invest heavily in research to develop solutions to help to decarbonise the transport sector.
I’m unsure about the picture, but it could be a number of buses or trucks connected to a large battery.
This press release on the BP web site, is the original source for The Times article and it is entitled BP To Invest Up To £50 million In New Global Battery Research And Development Centre In Britain.
The press release starts with these bullet points.
- bp continuing to invest in the UK, with new investment of up to £50 million for new electric vehicle battery testing centre and analytical laboratory in Pangbourne.
- Aims to advance development of engineering, battery technology and fluid technology and engineering into new applications such as electric vehicles, charging and data centres.
- New facilities at its Castrol headquarters and technology centre expected to open in 2024, supporting the technology, engineering and science jobs housed there today.
I find these sentences interesting.
new applications such as electric vehicles, charging and data centres
This sentence is a bit of a mess as electric vehicles are not new, charging is well established and what have data centres got to do with batteries.
I have a friend, who runs a large fleet of electric buses and charging is a problem, as getting the required number of MWhs to the garage can be a problem in a crowded city.
But could it be, that BP are thinking of a battery-based solution, that trickle-charges when electricity is affordable and then charges buses or other vehicles as required, throughout the day?
I believe that a battery based on process engineering like Highview Power’s CRYOBattery could be ideal in this situation.
- Effectively, the bus garage or transport parking would have its own high capacity battery-powered charging network.
- The storage capacity of the battery would be geared to the daily charge load of the vehicles.
- It would reduce the cost of electricity to the operator.
Such a battery might also be ideal to power a battery charging station.
I don’t know much about data centres, except that they need a lot of electricity.
Would driving data centres from a battery, that was trickle-charged overnight mean that the cost of electricity was reduced?
bp today unveiled plans to invest up to £50 million (around $60 million) in a new, state-of-the-art electric vehicle (EV) battery testing centre and analytical laboratory in the UK
There are a lot of battery ideas in the pipeline, so will one of the tasks be to find the best batteries for BP’s needs?
The site already undertakes research and development of fuels, lubricants and EV fluids and aims to become a leading hub for fluid technologies and engineering in the UK
You don’t think of lubricants being associated with electric vehicles, but obviously BP thinks it’s a serious enough topic to do some research.
The new facilities will help advance the development of leading fluid technologies and engineering for hybrid and fully battery electric vehicles, aiming to bring the industry closer to achieving the key tipping points for mainstream electric vehicle (EV) adoption.
This is self-explanatory.
Castrol ON advanced e-fluids manage temperatures within the battery which enables ultra-fast charging and improves efficiency, which help EVs to go further on a single charge and extend the life of the drivetrain system
Lubrication helps the world go round.
In addition, the advanced e-fluid technologies and engineering can be applied to other industries such as thermal management fluids for data centres where demand is rising exponentially
This is an interesting application and it will become increasingly important.
The growth of EV fluids is a huge opportunity, and we aim to be the market leader in this sector
I didn’t realise that EV fluids were so important.
The press release says this about the current status.
Two thirds of the world’s major car manufacturers use Castrol ON EV fluids as a part of their factory fill and we also supply Castrol ON EV fluids to the Jaguar TCS Racing Formula E team.
This press release on the Castrol web site is entitled CASTROL ON: Range Of Advanced E-Fluids For Mobility On Land, Sea And In Space.
This is the Castrol ON E-Fluids home page.
Where Will BP Need Batteries?
I can see the following applications are in BP’s sight from this press release.
- Charging fleets of buses and trucks at their garage.
- Powering battery-charging stations at filling stations.
- Providing uninterruptable electricity feeds.
- Powering data centres.
I will give a simple example.
Suppose a bus company wants to electrify the buses in a town.
- They will have thirty double-deck buses each with a 500 kWh battery.
- Wrightbus electric buses charge at 150 kW.
- Charging all buses at the same time would need 4.5 MW
- Each bus will need to be charged overnight and once during the day.
- This means the bus company will need 30 MWh of power per day.
- The largest wind turbines today are around 12 MW and have a capacity factor of 30 %.
- A single turbine could be expected to generate 86 MWh per day.
It looks to me, that a battery in the garage which could provide an output of 5 MW and had a capacity of 100 MWh would link everything together and support the following.
- A fleet of thirty buses.
- All buses charged overnight and at one other time.
- A 12 MW wind turbine.
- Power for the offices and other facilities.
- The battery would provide backup, when there is no wind.
- There would also be a mains connection to the battery for use, when the wind turbine failed.
The size of the battery and the turbine would depend on the number of vehicles and how often, they were to be charged.
BP could replace diesel sales to the bus or transport company, with leasing of a zero-carbon charging system.
Simple systems based on one or two wind turbines, solar panels and a battery would have several applications.
- Charging fleets of buses and trucks at their garage.
- Powering battery-charging stations at filling stations.
- Providing uninterruptable electricity feeds.
- Powering data centres
- Powering farms
- Powering new housing estates
- Powering factories
I can see this becoming a big market, that big energy companies will target.
Are BP planning to develop systems like this, as many of those, who might buy a system, are already their customers?
Choosing the best batteries and designing the system architecture would appear to be within the remit of the new Research Centre at Pangbourne.
Supporting Wind Farms
BP could certainly use a 2.5 GW/30 GWh battery at each of the three large wind farms; Mona, Morgan and Morven, that they are developing in the Irish Sea and off Aberdeen. These wind farms total 5.9 GW and a battery at each one, perhaps co-located with the offshore sub-station could mean that 5.9 GW was much more continuous.
The wind farms would be like virtual nuclear power stations, without any nuclear fuel or waste.
It would also mean that if the wind farm wasn’t needed and was told to switch off, the electricity generated could be stored in BP’s battery.
How many of BP’s other developments around the world could be improved with a co-located battery?
Process Technology
I am very keen on Highview Power’s CRYOBattery, but I do think that some parts of the design could benifit from the sort of technology that BP has used offshore and in the oil industry.
So will BP’s new battery research include offering advice to promising start-ups?
Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?
This Google Map shows a 3D image of liquified natural gas (LNG) tanks at South Hook LNG Terminal near Milford Haven.
Note that images of these tanks under construction on the Internet, show that there is an underground portion of the tanks.
This page on the CIMC-ENRIC web site is entitled Successful Delivery Of 5,000M3 LNG Single Containment Tank Project. The page shows the design of the LNG tank.
As the density of liquid air is 870 kg/m3, a 5,000 cubic metre tank would contain 4,350 tonnes of liquid air at −194.35 °C and atmospheric pressure.
How much energy would be needed to create 4,350 tonnes of liquid air?
In this document, this is said about compressing natural gas with an electric drive.
It is the most-energy efficient technology with 230 kWh per ton of LNG.
As air and natural gas have molecules of similar weight, would 230 kWh per tonne be applicable to liquid air.
If it is, then around a GWh of electricity will be needed to create the liquid air.
This Wikipedia entry is entitled Cryogenic Energy Storage and describes Highview Power’s CRYOBattery.
This section describes the operation of the CRYOBattery.
When it is cheaper (usually at night), electricity is used to cool air from the atmosphere to -195 °C using the Claude Cycle to the point where it liquefies. The liquid air, which takes up one-thousandth of the volume of the gas, can be kept for a long time in a large vacuum flask at atmospheric pressure. At times of high demand for electricity, the liquid air is pumped at high pressure into a heat exchanger, which acts as a boiler. Air from the atmosphere at ambient temperature, or hot water from an industrial heat source, is used to heat the liquid and turn it back into a gas. The massive increase in volume and pressure from this is used to drive a turbine to generate electricity.
Note.
- The Claude cycle is described in this Wikipedia entry.
- The liquid air takes up one-thousandth of the volume of the gas.
- Wikipedia suggests that Highview claim the process has a round trip efficiency of 70 %.
Having done calculations in the past with chemical reactions in a series of large vessels, the dynamics can be strange and I wouldn’t be surprised that as Highview learn more about the process and add more and better ways of recycling heat and coolth, efficiencies will improve.
Certainly, in the process I mathematically-modelled in the 1970s, when I worked for ICI, I remember that one large reaction vessel performed better than four or five smaller ones with the same total volume.
Hence my thought that perhaps one large containment tank could be the most efficient design.
I also think, that the design of LNG tanks must have improved significantly over the last few years, as the transport of LNG has increased in importance.
Form Energy And The UK
This article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, is proving to be a mine of information about the development of the UK Power Network.
Reliable information about US startup; Form Energy has been hard to find.
But the Telegraph article has these three paragraphs on Form Energy.
Form Energy in Boston – backed by Jeff Bezos and Bill Gates – is working on an iron-air “rust” battery based on the reversible oxidation of iron pellets. It does not require rare and polluting minerals such as vanadium, and will have a 100-hour range.
“The modules will produce electricity for one-tenth the cost of any technology available today for grid storage,” the company told Recharge.
Form Energy has been working with National Grid to map out the economics of UK renewables with storage, and how to cope with future curtailment. And it too praises the UK as a global trailblazer, though its pilot project next year will be in Minnesota.
Note.
- Iron certainly, isn’t an exotic material.
- A hundred hour range is claimed.
- If National Grid have been working with Form Energy, is it reasonable to assume, that they have been working with Highview Power?
- Good to see that Form Energy praises the UK as a global trailblazer. I have noted several times, that the Department for Business, Energy and Industrial Strategy seems to be well-advised.
Will National Grid put in one of Form Energy’s batteries? It would be a prudent thing to do, to make sure you get the best.
Highview Power’s Second Commercial System In Yorkshire
This is all that Highview Power say about their proposed system in Yorkshire, on their web site.
Highview Power’s second commercial renewable energy power station in the UK is a 200MW/2.5GWh facility in Yorkshire. This is the first of 18 sites for UK wide deployment strategically located to benefit from the existing transmission infrastructure.
I have a few thoughts.
How Does The Size Of This System Fit With Other Systems?
According to the Highview Power web site the Manchester system is a 50MW/300MWh facility, but Wikipedia has this system as a 50MW/250MWh.
In this article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, it is stated that they are planning a battery with this specification, location and timeline.
- 2.5 GW output
- 30 GWh of storage
- Located on Humberside
- Delivery in late 2024.
This CRYOBattery is an absolute monster.
Will The Humberside CRYOBattery Be Built At Creyke Beck Substation?
In Highview Power’s Plan To Add Energy Storage To The UK Power Network, I came to the conclusion, that the Humberside CRYOBattery will most likely be built near Creyke Beck substation, which is close to Cottingham.
- Dogger Bank A, Dogger Bank B and Hornsea 4 offshore wind farms will all be connected to the Creyke Beck substation.
- These wind farms have a total capacity of 3.4 GW.
- The Humberside CRYOBattery, now looks to have a maximum output of 2.5 GW.
- It looks like the Humberside CRYOBattery would be a well-matched backup to the three planned wind farms and perhaps even a few more turbines.
Building the Humberside CRYOBattery at Creyke Beck substation would appear to be a sensible decision.
Is Cottingham In Humberside, Yorkshire Or Both?
The Wikipedia entry for the village is named Cottingham, East Riding of Yorkshire, says this.
A golf course and leisure club on Wood Hill Way, and a major (400/275 kV AC) electricity substation “Creyke Beck”, lie just outside the formal boundaries of the parish, within Skidby civil parish.
Skidby is definitely in Yorkshire.
Where Are The Other Seventeen Sites?
The Yorkshire facility is indicated to be one of 18 sites on the Highview Power web site. Where are the other seventeen?
All we know is that they will be strategically located to benefit from the existing transmission infrastructure.
This is said in the Wikipedia entry, which is entitled High-Voltage Substations In The United Kingdom.
In 2020 there were 179 400 kV substations and 137 275 kV substations.
He who pays the money, makes the choice!
Has The Company Changed Direction?
I wrote Highview Power Names Rupert Pearce Chief Executive Officer on April 12th, 2022.
- Since then, the Vermont and Chile projects have disappeared from the web site and projects in Yorkshire and Australia have been added.
- The web site has also been improved.
- As new CEOs often do, is Rupert Pearce refocussing the company?
Are they also looking in detail at current projects?
Has The Yorkshire Project Grown Substantially?
Consider.
- National Grid are a company that has improved its image and engineering in recent years.
- It has shown it can obtain finance for infrastructure from the City of London and respected financial institutions.
- National Grid probably have extensive computer models of their electricity network.
- National Grid knows it must add energy storage to their electricity network.
- National Grid pays almost a billion pounds a year to wind farm operators to shut them down.
Eventually saving up to a billion pounds would be a good reason to have a small bet on promising technology.
Did Rupert Pearce ask his engineers to design the largest CRYOBattery they can?
Did National Grid have a count up sand find that twenty CRYOBatteries would cover all the strategic points on their transmission infrastructure?
According to the figures on the Highview Power web site (200 MW/2.5 GWh), eighteen systems like the one proposed for Yorkshire would have.
- A total output of 3.6 GW
- A total storage capacity of 45 GWh
The figures given in the article in the Telegraph (2.5 GW/30 GWh) for the very large system, would mean that twenty systems would have.
- A total output of 50 GW
- A total storage capacity of 600 GWh
These figures are between thirteen and fourteen times larger than those originally proposed.
Building The System
The Highview Power web site, says this about the deployment of eighteen systems.
UK wide deployment strategically located to benefit from the existing transmission infrastructure.
This Google Map shows the Creyke Beck substation.
Could 30 GWh of liquid-air storage be accommodated on the site?
I can see a large insulated sphere, partly buried in the ground being used.
Designing, building and testing the first system will probably be the most difficult part of the project.
- But once the first system is successfully working reliably, the roll-out of other systems can be started.
- The biggest problem will probably be planning permissions, so the systems must be designed to be sympathetic to the local environment.
I can certainly see, twenty of these systems in the UK, but how many others will we see worldwide?
