How Siemens Gamesa Could Give Coal Plants a Second Life
This article on Greentech Media is a must-read as it makes you think. This is the sub-title.
The ETES thermal battery can offer coal plants a new life as heat and power storage hubs. The first customer for a full-size version could be on-board as early as next year.
It talks about the philosophy of reusing coal-fired power station sites and some of their equipment like turbines.
It is an idea much more applicable to countries like the US and Germany rather than the UK, as they still have lots of operational coal-fired power stations and and we only have a few.
I first came across this idea, when Highview Power were talking about their 50/MW/400 MWh installation in Vermont, which was to be built on the site of a demolished coal-fired power station. The utility company and Highview were in that case just reusing the grid connection.
But then I’ve heard of other energy storage systems using old power station sites.
And not to forget that Highview Power’s installation at Carrington is close to a gas-fired power station.
Highview Power Unveils $1bn Of Liquid-Air Energy Storage Projects In Spain
The title of this post, is the same as that of this article on Recharge Magazine.
The article is based on this press release from Highview Power, which is entitled Highview Power Developing 2 GWh of Liquid Air Long Duration Energy Storage Projects in Spain.
This is the introductory paragraph from the press release.
Highview Power, a global leader in long duration energy storage solutions, announced today it is developing up to 2 GWh of long duration, liquid air energy storage projects across Spain for an estimated investment of around $1 billion. These projects will enable several Spanish regions to move towards their net zero emissions target.
The press release also says this about location and size.
Highview Power is planning to develop up to seven CRYOBattery™ projects ranging from 50 MW/300 MWh in Asturias, Cantabria, Castilla y Leon, and the Canary Islands.
Three of these areas are in Northern Spain and the other is a group of islands.
As Spain has at least two large pumped storage systems, perhaps geography rules this proven technology out in these areas.
System Modularity
According to the Wikipedia entry for Highview Power, the two current CRYOBatteries under development are sized as follows.
- Carrington, Manchester, UK – 50 MW/250 MWh – Under construction
- Vermont, USA – 50 MW/400 MWh – Under development
Do the figures indicate that several systems will share the same 50 MW core power system, with a number of liquid air tanks to give the appropriate capacity?
I have extensively modelled chemical plants in my past to see, how different sizes work and I am fairly certain, that Highview Power have developed a design, that is extremely flexible.
It looks like if initial calculations show that a system capable of supplying 50 MW for five hours is needed, but operation proves that a capacity of six hours would be better, that all Highview Power need to do is add another 50 MWh tank.
This is surely an operator’s dream, as if say a developer builds a thousand dwellings and/or a windfarm nearby and more energy storage is needed, an appropriate number of extra tanks can be added.
Sourcing The 50 MW Core Power System
I talked about how the first system at Carrington will use a system from MAN Energy Solutions in MAN Energy Partners With Highview Power On Liquid-Air Energy-Storage Project.
This surely is an approach that minimises risk.
Sourcing The Storage Tanks
I have been searching the Internet for manufacturers of cryogenic gas tanks and I’ve found them in countries like Australia, Brazil, Germany, India, South Africa, Spain, the UK and the US.
But then most hospitals have one for their liquid oxygen.

They are not difficult to find.
Spain And Renewable Energy
Spain is a large producer of renewable energy and also a leader in wind and solar power technology.
See Renewable Energy in Spain on Wikipedia for more details.
Siemens Gamesa, which was created by a merger of a German and a Spanish company and is headquartered at Zamudio in Spain, have also developed the Siemens Gamesa ETES, which is a volcanic rock-based energy storage system about the same size of Highview Power’s CRYOBattery.
Conclusion
It looks to me, that Highview Power have closed a good sale.
Rolls-Royce Seeks Private Funds To Power Nuclear Project
The title of this post, is the same as that of this article on The Times.
The article is based on this press release on the Rolls-Royce web site, which is entitled More Power And Updated Design Revealed As Nuclear Power Team Targets First Place In The Assessment Queue In Autumn 2021.
This is the first two paragraphs.
The consortium, led by Rolls-Royce, which is creating a compact nuclear power station known as a small modular reactor (SMR), has revealed its latest design and an increase in power as it completes its first phase on time and under budget.
It has also announced it is aiming to be the first design to be assessed by regulators in the second half of 2021 in the newly-opened assessment window, which will keep it on track to complete its first unit in the early 2030s and build up to 10 by 2035.
It would appear that they are following AstraZeneca’s example and building the relationships with the regulators early, so the process of regulation doesn’t delay entry into service.
An Updated Design
These two paragraphs describe the design changes.
As the power station’s design has adjusted and improved during this latest phase – with more than 200 major engineering decisions made during this latest phase – the team has optimised the configuration, efficiency and performance criteria of the entire power station , which has increased its expected power capacity, without additional cost, from 440 megawatts (MW) to 470MW.
The refreshed design features a faceted aesthetic roof; an earth embankment surrounding the power station to integrate with the surrounding landscape; and a more compact building footprint, thanks to successes optimising the use of floor space.
These changes appear to be positive ones.
Transformation To A Focussed Business
Rolls-Royce are transforming the current consortium to an as yet unnamed stand-alone business, as detailed in this paragraph from the press release.
With a focus on continuing its progress at pace, the UK SMR team is transitioning from being a collaborative consortium to a stand-alone business, which will deliver a UK fleet of power stations to become a low carbon energy bastion alongside renewables, while securing exports to make the power station a key part of the world’s decarbonisation toolkit.
Are Rolls-Royce aiming to repeat the success they’ve had with Merlins in World War II and large turbofan engines for airliners with small modular nuclear reactors that decarbonise the world? The strategy is certainly not going against the heritage of the company.
Use Of A Small Modular Nuclear Reactor
This paragraph from the press release outlines a few uses.
The power station’s compact size makes it suitable for a variety of applications, helping decarbonise entire energy systems. Each power station can supply enough reliable low carbon power for around one million* homes, or be used to power net zero hydrogen and synthetic aviation fuel manufacturing facilities, desalination plants or energy intensive industrial sites.
Their size would appear to increase the number of applications.
Hydrogen Production
I particularly like the idea of using an SMR to produce hydrogen for chemical feedstock or to make steel.
I indicated this in Will INEOS And Rolls-Royce Get Together Over Hydrogen Production?
I estimate that a 470 MW SMR would produce around 4,900 tonnes of hydrogen per day.
The numbers certainly seem convenient.
Cost Of Energy And Capital Costs
Tom Samson, Chief Executive Officer of the UK SMR consortium is quoted as saying.
Nuclear power is central to tackling climate change, securing economic recovery and strengthening energy security. To do this it must be affordable, reliable and investable and the way we manufacture and assemble our power station brings down its cost to be comparable with offshore wind at around £50 per megawatt-hour.
Hinckley Point C has a strike price of over £80 per megawatt-hour.
The release also gives a price of around £2.2 billion per unit dropping to £1.8 billion by the time five have been completed.
Benefits To The UK
The press release lists these benefits to the UK.
- create 40,000 regional UK jobs by 2050
- generate £52 billion of economic benefit
- have 80% of the plant’s components sourced from the UK
- target an additional £250 billion of exports – memoranda of understanding are already in place with Estonia, Turkey and the Czech Republic
The value of exports would indicate export sales of over a hundred reactors.
Lifetime
The press release indicates the following about the lifetime of the reactors.
- The reactor will operate for at least 60 years.
- The design, which will be finalised at the end of the regulatory assessment process, proposes that all used fuel will be stored on each site for the lifetime of the plant.
I would assume that Rolls-Royce are developing a philosophy for taking the SMRs apart at the end of their life.
Construction
This paragraph from the press release talks about the construction process.
The power station’s design cuts costs by using standard nuclear energy technology used in 400 reactors around the world, so no prototyping is required. The components for the power station are manufactured in modules in factories, before being transported to existing nuclear sites for rapid assembly inside a weatherproof canopy. This replicates factory conditions for precision activities and further cuts costs by avoiding weather disruptions. The whole sequence secures efficiency savings by using streamlined and standardised processes for manufacturing and assembly, with 90% of activities carried out in factory conditions, helping maintain extremely high quality. In addition, all spoil excavated will be reused on site to build the earth embankment, removing the need for it to taken off site, reducing road journeys that are both financially and environmentally costly.
I have talked to project managers, who have assembled factory-built railway stations and their experiences would back the Rolls-Royce method of construction.
My project management knowledge would also indicate, that the construction of an SMR could be much more predictable than most construction projects, if the factory-built modules are built to the specification.
Funding
According to the article in The Times, the consortium now seems to be in line for £215 million of Government funding, which will unlock £300 million of private funding.
Conclusion
It looks like this project will soon be starting to roll.
USTDA Grants $1 Million To Support Battery Storage Project In Africa
The title of this post, is the same as that of this article on Running Africa.
This is the first two paragraphs.
The United States Trade and Development Agency (USTDA), an independent body of the US government, has reportedly issued a grant of just under USD 1 million to support feasibility studies for large-scale battery storage schemes in Senegal and Mozambique.
Notably, these large-scale battery storage projects have been grouped with wind energy in Mozambique in Southeast Africa as well as Senegal in West Africa.
A Dutch company seems to be doing the development.
We need more aid projects like these, as with electricity and clean water life can be so much better!
Energy Storage System For Dominica
This title of this post is taken a section of this round-up article on pv magazine.
This is said.
A $50 million hurricane-resistant battery energy storage system is coming to the Caribbean island of Dominica through an investment by the UAE-Caribbean Renewable Energy Fund. The project includes a 5 MW/2.5 MWh battery energy storage system.
The system is intended to stabilize the electricity grid and deliver reserve power and frequency control to the extreme weather-prone nation.
Dominica is building a 7 MW geothermal plant to help drive the country’s energy mix to 51% renewables. One government program enables foreign investors to obtain Dominica’s citizenship in exchange for a $100,000 investment to the Economic Diversification Fund, or $200,000 into pre-approved luxury real estate that supports Dominica’s ecotourism.
Dominica uses the investments for energy security, infrastructure, and housing as it aims to be one of the world’s first climate-resilient nations, as pledged by the government after Hurricane Maria hit the island in 2017.
The UAE-CREF initiative is financed by the Abu Dhabi Fund for Development, the UAE’s national entity for international development aid. The fund is a partnership between the Ministry of Foreign Affairs and Cooperation and Masdar, which is leading project design and implementation. In March 2019, the first three renewable energy projects were inaugurated.
Dominica is an island in the Eastern Caribbean, with a population of about 72,000.
This description is from Wikipedia.
It is the youngest island in the Lesser Antilles, and in fact it is still being formed by geothermal-volcanic activity, as evidenced by the world’s second-largest hot spring, called Boiling Lake.
I think that this could be a very good development and a model for other small islands with a friendly volcano underneath.
Do BP And The Germans Have A Cunning Plan For European Energy Domination?
The headline of this post may be slightly tongue in cheek, but I believe that a plan is being hatched.
Preamble
I’ll start with a preamble, where I’ll outline some of the factors behind what may be happening.
Decarbonisation
It is generally accepted by most people that there is a need to decarbonise everything we do.
And large oil companies like Shell, BP and others are starting to move in the same direction.
Hydrogen
Using hydrogen instead of fossil fuels is becoming one of the major routes to decarbonisation.
Hydrogen can be used for the following.
- Provide power for cars, buses, trucks, trains, locomotives and ships.
- Hydrogen can be used in steelmaking instead of coking coal.
- As a chemical feedstock to make ammonia, fertiliser and a large range of petrochemicals.
- I believe that hydrogen could be a viable fuel to power aircraft over thousands of miles.
Hydrogen will become the most common zero-carbon fuel.
Hydrogen And Natural Gas
In many applications hydrogen can replace natural gas, so for large users of natural gas, hydrogen offers a route to decarbonisation.
But hydrogen can also be mixed up to a level of around twenty percent in natural gas for partial decarbonisation of applications like space heating. Most industrial uses, boilers and appliances can be made to work very successfully with this mixture.
I grew up in the 1950s with coal gas, which according to Wikipedia had this composition.
- hydrogen 50%
- methane 35%
- carbon monoxide 10%
- ethylene 5%
- When we changed over in the 1970s, all my appliances were converted.
This is the UK government description of natural gas.
It contains primarily methane, along with small amounts of ethane, butane, pentane, and propane. Natural gas does not contain carbon monoxide. The by-products of burning natural gas are primarily carbon dioxide and water vapour. Natural gas is colourless, tasteless and odourless.
As with the conversion from coal-gas to natural gas, conversion from Natural gas to a hydrogen/natural gas mixture and eventually to hydrogen, will be a relatively painless process.
Note that carbon monoxide is a nasty poison and is not contained in either natural gas or hydrogen.
Green Hydrogen And Electrolysis Of Water
Green hydrogen is hydrogen produced exclusively from renewable energy sources.
Typically green hydrogen is produced by electrolysis of water using electricity produced by hydro, solar, tidal or wind.
The largest factory building electrolysers is owned by ITM Power.
- It is located in Rotherham.
- The factory has the capacity to build 1 GW of electrolysers in a year.
- Typical electrolysers have a capacity of several MW.
Ryze Hydrogen are building an electrolyser at Herne Bay, that will consume 23 MW of solar and wind power and produce ten tonnes of hydrogen per day.
Blue Hydrogen
‘Blue hydrogen is produced through a production process where carbon dioxide is also produced then subsequently captured via carbon capture and storage. In many cases the carbon dioxide is stored in depleted gas fields, of which we have plenty in the North Sea. Over the last few years, research has been ongoing into using the carbon dioxide. Applications in horticulture and agriculture, carbon structures and sustainable aviation fuel are being developed.
Shell have also developed the Shell Blue Hydrogen Process, where the carbon is extracted from methane as carbon dioxide and then stored or used.
CO2 In Greenhouse Horticulture
This paper from The Netherlands is called CO2 In Greenhouse Horticulture.
Read it and you might believe me, when I say, we’ll eat a lot of carbon in the form of tomatoes, salads and soft fruit. We’ll also buy flowers grown in a carbon-dioxide rich atmosphere.
Hydrogen As An Energy Transfer Medium
Every kilogram of natural gas when it burns releases energy, as it does in your boiler or gas hob. So it transfers energy in the form of gas from the gas well or storage tank to your house.
Electricity can also be transferred from the power station to your house using wires instead of pipes.
Hydrogen is being put forward as a means of transferring energy over hundreds of miles.
- Electricity is converted to hydrogen, probably using an electrolyser, which would be powered by zero-carbon electricity.
- The hydrogen is transferred using a steel pipe.
- At the destination, the hydrogen is either distributed to end-users, stored or used in a gas-fired power station, that has been modified to run on hydrogen, to generate electricity.
It sounds inefficient, but it has advantages.
- Long underwater cables have energy losses.
- Electrical connections use a lot of expensive copper.
- Re-use of existing gas pipes is possible.
- Oil and gas companies like BP and their contractors have been laying gas pipes on land and under water for decades.
If hydrogen has a problem as an energy transfer medium, it is that it us difficult to liquify, as this statement from Air Liquide illustrates.
Hydrogen turns into a liquid when it is cooled to a temperature below -252,87 °C. At -252.87°C and 1.013 bar, liquid hydrogen has a density of close to 71 kg/m3. At this pressure, 5 kg of hydrogen can be stored in a 75-liter tank.
To transport, larger quantities of hydrogen by ship, it is probably better to convert the hydrogen into ammonia, which is much easier to handle.
The Germans and others are experimenting with using liquid ammonia to power large ships.
Hydrogen As An Energy Storage Medium
The UK has a comprehensive National Transmission System for natural gas with large amounts of different types of storage.
This section of the Wikipedia entry is entitled Natural Gas Storage and lists ten large storage facilities in salt caverns and depleted onshore gas fields. In addition, several depleted offshore gas fields have been proposed for the storage of natural gas. Rough was used successfully for some years.
I can certainly see a network of hydrogen storage sites being developed both onshore and offshore around the UK.
Iceland
With its large amount of hydro-electric and geothermal energy, Iceland can generate much more electricity, than it needs and has been looking to export it.
The UK is probably the only country close enough to be connected to Iceland to buy some of the country’s surplus electricity.
There has been a proposal called Icelink, that would build an electrical interconnector with a capacity of around a GW between Iceland at the UK.
But the project seems to have stalled since I first heard about it on my trip to Iceland in 2014.
Could the engineering problems just be too difficult?
The Waters Around The Northern Parts Of Great Britain
Look at a map of the UK and particularly Great Britain and there is a massive area of water, which is not short of wind.
Between Norway, Denmark, Germany, The Netherlands, the East Coast of England, the Northern Coasts of Scotland and Iceland, there are only a few islands.
- Faroes
- Orkney
- Shetlands
To be complete we probably must include hundreds of oil and gas rigs and platforms and the Dogger Bank.
- Oil and gas companies probably know most there is to know about these waters.
- Gas pipelines connect the production platforms to terminals at Sullom Voe and along the East Coast from St. Fergus near Aberdeen to Bacton in Norfolk.
- Many of the oil and gas fields are coming to the end of their working lives.
I believe that all this infrastructure could be repurposed to support the offshore wind industry.
The Dutch Are Invading The Dogger Bank
The Dogger Bank sits in the middle of the North Sea.
- It is roughly equidistant from Norway, Denmark, the Netherlands and the UK.
- The Western part is in UK territorial waters.
- The Eastern part is mainly in Dutch territorial waters.
On the UK part, the Dogger Bank Wind Farm is being developed.
- The turbines will be between 78 and 180 miles from the shore.
- It could have a capacity of up to 5 GW.
- It would be connected to East Yorkshire or Teesside.
On their side of the Dogger Bank, the Dutch are proposing the North Sea Wind Power Hub.
- It is a collaboration between the Dutch, Germans, and Danes.
- There have been reports, that up to 110 GW of turbines could be installed.
- It will be connected to the Dogger Bank Wind Farm, as well as The Netherlands.
It is also planned that the connections to the Dogger Bank will create another interconnector between the UK and the Continent.
The Shetland Islands
The Shetland Islands are the only natural islands with a large oil and gas infrastructure in the waters to the North of Great Britain.
They have a large gas and oil terminal at Sullom Voe.
- Oil is transported to the terminal by pipelines and tanker.
- Oil is exported by tanker.
- Gas is imported from oil and gas fields to the West of the islands through the West of Shetland Pipeline.
- The gas-fired Sullom Voe power station provide about 80 MW of power to the islands.
This document on the APSE web site is entitled Future Hydrogen Production In Shetland.
It describes how the Shetland Islands can decarbonise and reposition themselves in the energy industry to be a major producer of hydrogen.
It gives these two facts about carbon emissions in the Shetlands Islands and Scotland.
- Annual per capita CO2 emissions in the Shetland Islands are 17 tonnes.
- In Scotland they are just 5.3 tonnes.
By comparison, the UK average is 5.55 and Qatar is 37.29.
Currently, the annual local market for road, marine and domestic fuel calculated
at around £50 million.
These are the objectives of the Shetland’s plan for future hydrogen production.
- Supply 32TWh of low carbon hydrogen annually, 12% of the expected UK total requirement, by 2050
- Provide more than 3GW of wind generated electrical power to Shetland, the UK grid, generating green hydrogen and electrification of the offshore oil and gas sector
- Enable all West of Shetland hydrocarbon assets to be net zero by 2030 and abate 8Mt/year CO2 by 2050
- Generate £5bn in annual revenue by 2050 and contribute significantly to the UK Exchequer.
They also envisage removing the topsides of platforms, during decommissioning of mature East of Shetland
oil fields and repurposing them for hydrogen production using offshore wind.
That is certainly a powerful set of ambitions.
This diagram from the report shows the flow of electricity and hydrogen around the islands, terminals and platforms.
Note these points about what the Shetlanders call the Orion Project.
- Offshore installations are electrified.
- There are wind turbines on the islands
- Hydrogen is provided for local energy uses like transport and shipping.
- Oxygen is provided for the fish farms and a future space centre.
- There is tidal power between the islands.
- There are armadas of floating wind turbines to the East of the islands.
- Repurposed oil platforms are used to generate hydrogen.
- Hydrogen can be exported by pipeline to St. Fergus near Aberdeen, which is a distance of about 200 miles.
- Hydrogen can be exported by pipeline to Rotterdam, which is a distance of about 600 miles.
- Hydrogen can be exported by tanker to Rotterdam and other parts of Europe.
It looks a very comprehensive plan!
The German Problem
Germany has an energy problem.
- It is a large energy user.
- It has the largest production of steel in Europe.
- It prematurely shut some nuclear power stations.
- About a quarter of electricity in Germany comes from coal. In the UK it’s just 1.2 %.
- It is very reliant on Russian natural gas.
- The country also has a strong Green Party.
- Germany needs a lot more energy to replace coal and the remaining nuclear.
- It also needs a lot of hydrogen to decarbonise the steel and other industries.
Over the last few months, I’ve written these articles.
- Sale To Linde Of World’s Largest PEM Electrolyser
- Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal
- WindH2 Hydrogen Project Commissioned In Germany
- Morocco Could Produce Up To 4% Of World’s Green Hydrogen By 2030
- Get H2 Partners Propose Green Hydrogen Pipeline In Europe
- Alstom Hydrogen Trains Complete Trials
Germany seems to have these main objectives.
- Increase their supply of energy.
- Ensure a plentiful supply of hydrogen.
They appear to be going about them with a degree of enthusiasm.
BP’s Ambition To Be Net Zero By 2050
This press release from BP is entitled BP Sets Ambition For Net Zero By 2050, Fundamentally Changing Organisation To Deliver.
This is the introductory paragraph.
BP today set a new ambition to become a net zero company by 2050 or sooner, and to help the world get to net zero. The ambition is supported by ten aims
The ten aims are divided into two groups.
Five Aims To Get BP To Net Zero
These are.
- Net zero across BP’s operations on an absolute basis by 2050 or sooner.
- Net zero on carbon in BP’s oil and gas production on an absolute basis by 2050 or sooner.
- 50% cut in the carbon intensity of products BP sells by 2050 or sooner.
- Install methane measurement at all BP’s major oil and gas processing sites by 2023 and reduce methane intensity of operations by 50%.
- Increase the proportion of investment into non-oil and gas businesses over time.
I would assume that by gas, they mean natural gas.
Five Aims To Help The World Get To Net Zero
These are.
- More active advocacy for policies that support net zero, including carbon pricing.
- Further incentivise BP’s workforce to deliver aims and mobilise them to advocate for net zero.
- Set new expectations for relationships with trade associations.
- Aim to be recognised as a leader for transparency of reporting, including supporting the recommendations of the TCFD.
- Launch a new team to help countries, cities and large companies decarbonise.
This all does sound like a very sensible policy.
BP’s Partnership With EnBW
BP seemed to have formed a partnership with EnBW to develop offshore wind farms in the UK
Their first investment is described in this press release from BP, which is entitled BP Advances Offshore Wind Growth Strategy; Enters World-Class UK Sector With 3GW Of Advantaged Leases In Irish Sea.
This is the first five paragraphs.
bp and partner EnBW selected as preferred bidder for two highly-advantaged 60-year leases in UK’s first offshore wind leasing round in a decade.
Advantaged leases due to distance from shore, lower grid cost, synergies from scale, and faster cycle time.
Projects expected to meet bp’s 8-10% returns aim, delivering attractive and stable returns and integrating with trading, mobility, and other opportunities.
Annual payments expected for four years before final investment decisions and assets planned to be operational in seven years.
In the past six months bp has entered offshore wind in the UK – the world’s largest market – and the US – the world’s fastest-growing market.
Note.
- EnBW are Energie Baden-Wuerttemberg AG, who, according to Wikipedia, are the third largest utilities company in Germany.
- It also appears, that EnBW have developed wind farms.
BP have issued this infographic with the press release.
Note.
- The lease areas don’t appear to be far from the Morecambe Bay gas field.
- The Morecambe Bay gas field is coming to the end of its life.
- The Morecambe Bay gas field is connected to the Rampside gas terminal at Barrow-in-Furness.
- At peak production 15 % of the UK’s natural gas came from Morecambe Bay.
I just wonder, if there is a cunning plan.
Could the platforms be repurposed to act as electrical hubs for the wind turbines?
- 3GW of electricity would produce 55 tonnes of hydrogen per day.
- The hydrogen would be exported to the Rampside gas terminal using the existing pipelines.
- There may be savings to be made, as HVDC links are expensive.
- BP either has the engineering to convert the platforms or they know someone who does.
- Would the industrial complex at Barrow-in-Furnace and the nearby Sellafield complex have a use for all that hydrogen?
- Or would the hydrogen be used to fuel Lancashire’s buses and trucks on the M6.
It certainly looks to me, that it could be a possibility, to bring the energy ashore as hydrogen.
BP Seeking Second Wind Off Scotland
The title of this section, is the same as that of this article in The Times.
These are the first two paragraphs.
BP is preparing to bid for the rights to build wind farms off Scotland as it signals no let-up in expansion after a £900 million splurge on leases in the Irish Sea.
The London-based oil giant caused waves in February by offering record prices to enter the UK offshore wind market through a Crown Estate auction of seabed leases off England and Wales.
As I said earlier.
- The Shetland Islands are developing themselves as a giant hydrogen factory.
- There are pipelines connecting platforms to the Sullom Voe Terminal.
- There are plans to convert some of the redundant platforms into hydrogen production platforms.
- The islands will be developing ways to export the hydrogen to the South and Europe.
BP also operates the Schiehallion oil and gas field to the West of the Shetlands, which is connected to the Sullom Voe Terminal by the West of Shetland pipeline.
Could BP and EnBW be coming to the party?
They certainly won’t be arriving empty-handed.
Does BP Have Access To Storage Technology?
I ask this question because both the Morecambe Bay and Shetland leases could be built with co-located depleted gas fields and offshore electrolysers.
So could hydrogen gas be stored in the gas fields?
I think it could be a possibility and would mean that hydrogen would always be available.
Could Iceland Be Connected To Schiehallion Via A Gas Pipeline?
I estimate that Iceland and Schiehallion would be about six hundred miles.
This wouldn’t be the longest undersea gas pipeline in the world as these two are longer.
- Langeled – 725 miles
- Nord Stream – 759 miles
The Langeled pipeline cost £1.7 billion.
Conclusion
I think there’s more to the link-up between BP and EnBW.
I am fairly certain, that BP are thinking about converting some redundant gas platforms into hubs for wind turbines, which use the electricity to create hydrogen, which is then exported to the shore using existing gas pipelines and onshore terminals.
Could it be said, that BP will be recycling oil and gas platforms?
I feel that the answer is yes! Or at least maybe!
The answer my friend is blowing in the wind!
Albannach Island: Multi-Million Pound Green Energy Plans Would Create 300 Construction Jobs
The title of this post, is the same as that of this article on the Aberdeen Press and Journal.
This is the introductory paragraphs.
A multi-million pound green energy power venture – called Albannach Island – would give a much-needed jobs boost to Caithness.
Highview Power is behind the plans to build a liquid air energy storage plant in a disused part of a quarry in Spittal, adjoining the most northerly stretch of the A9.
The plant appears to be a 50MW/250 MWh CRYOBattery, that is probably similar in size to the one currently being built by Highview Power at Carrington, near Manchester.
This Google map of the North-East corner of Scotland, shows the location.
Note.
- John O’Groats is in the North-East corner of the map.
- The red arrow shows the location of the A & D Sutherland quarry, where the Highview Power’s CRYOBattery will be located.
This second Google map shows the location in more detail.
Note.
- The A & D Sutherland quarry is in the South-East corner of the map.
- The CRYOBattery will use five acres at the North of the quarry site.
- In the North-West corner of the map is the Spittal sub-station.
The Spital sub-station is described like this on the Scottish and Southern Electricity Networks web site.
Spittal is a new electricity convertor station and is part of the £1.1bn Caithness-Moray project which represents the largest investment in the north of Scotland’s electricity network since the hydro development era of the 1950s and is the largest capital investment project undertaken by the SSE Group to date. It is also the largest Living Wage contract ever awarded in the UK, demonstrating SSEN’s strong commitment to ensure all employees working on its sites get a fair day’s pay for a fair day’s work.
It looks like the CRYOBattery will be the cherry on top of the very billion pound cake of the Caithness-Moray Link.
Conclusion
We’ll be seeing more battery installations like this to stabilise power.
Nothing is said in the article, about who is paying for the battery. The only clue is it talks about Highview as a London-based conglomerate.
I wonder, if the company has formed a partnership with one of the energy trusts or a battery site developer.
Australia’s First Net-Zero Hybrid Power Station Gets The Green Light
The title of this post, is the same as that of this article on the Australian Broadcasting Company.
This is the first paragraph.
Australia’s first power plant — capable of running on both hydrogen and natural gas — will be built in NSW, following an agreement between the private sector and both state and federal governments.
The article also makes these key points.
- The gas power plant could begin using green hydrogen as early as 2025.
- EnergyAustralia plans to buy 200,000kg of green hydrogen a year — equivalent to five per cent of the plant’s fuel use.
- The Illawarra project is expected to deliver a $300-million boost to the economy and support about 250 jobs during construction.
But it doesn’t say, where the green hydrogen is coming from.
Is it going to be produced by solar power in Australia’s hot interior or is it going to be imported by ship at the hydrogen hub at Port Kembla?
Gravity, The Ultimate In Energy Storage
This is a must read article on explica.co.
It talks about three methods of storing energy using gravity.
Gravitricity
Gravitricity is under development in Edinburgh
Energy Vault
An image explaining the principle of Energy Vault is also shown.
The Energy Vault web site has some impressive video.
They could be a company to watch. Especially, when they have a battery working, where it can be viewed in action, as it will look like a gigantic many-armed robotic child, playing with thirty-five tonne concrete bricks.
Vázquez Figueroa
This writer from the Canaries has come up with an interesting idea, which combines an energy storage system with water desalination. This is his website. Unfortunately for me, it’s in Spanish only.
This is explica.co’s description of the idea.
Figueroa’s idea is conceptually very simple. Pumping water from the sea to an elevated reservoir, using renewable energy for the process when it is not in demand. Then, in a total win-win, the writer proposes to release that water into a vacuum (as in a traditional hydroelectric power station) which would move a turbine generating electricity. But also, and here’s the genius, that salty water could fall on a semi-permeable membrane, so that it desalinated. Clean electricity and fresh water for the same price. Who gives more?
It certainly sounds feasible.
It sounds to me, though it could be paired with another idea, I read about a couple of years ago.
- A reservoir would be built on a high place close to the sea.
- Pumps driven by the waves would pump seawater into the reservoir.
- When electricity is needed, water is released from the reservoir through turbines.
- There would be no reason, why the water discharged from the turbines couldn’t be desalinated.
Never underestimate the power of innovation. Especially, when it is fuelled by convivial company and appropriate beers!
Alternative Energy Storage Technologies To Challenge Electrochemistry
The title of this post, is the same as that of this article on Battery and Energy Storage Magazine.
It gives a good summary of two energy storage system; Highview Power and Gravitricity, that I rate highly promising.
It also gives details of a Danish system called Stiesdal Storage Technologies, which is developing a hot rocks energy storage system.
The article says this about the system.
The pumped-heat ESS uses pea-sized crushed basalt, rock in insulated steel tanks with the stored energy released by turbine.
SST CEO Peder Riis Nickelsen said: “The cost of crushed stone is at a totally different level per unit of energy than practically any other material for energy storage. Our charging and discharging system can utilise well-known technologies that have been applied for a century within other industries and are well-suited for mass production.”
The cost of materials is estimated to be €10 ($12) per kWh.
The first demonstration project, a 1-2MW, 24h capacity unit, will be installed at a power plant in Denmark next year, and will operate commercially.
This page on the Striesdal web site, explains the technology.
It sounds like the system uses very similar principles to Siemens Gamesa ETES, with a different heat storage medium.
Conclusion
At my last count, there now appears to be upwards of half-a-dozen viable alternatives to chemical batteries and traditional pumped storage. Some of the technologies are also backed, by large companies, organisations and countries, who can afford to take a long-term view.
I hope those, who claim that renewables will never power the world, have at least got the recipe for the cooking of humble pie ready.
