SSE Thermal Outlines Its Vision For The UK’s Net Zero Transition

The title of this post is the same as that of this news item from SSE Thermal.

This is the opening statement.

SSE Thermal, part of SSE plc, is calling on government to turbocharge the delivery of low-carbon technologies to help deliver a net zero power system by 2035.

Two paragraphs then outline what the company is doing.

The low-carbon developer is bringing forward multiple low-carbon projects across the UK. This includes Keadby 3 Carbon Capture Power Station in the Humber – which is being developed in collaboration with Equinor and recently became the first power CCS project in the country to receive planning permission – and Aldbrough Hydrogen Pathfinder, which would unite hydrogen production, storage and power generation in one location by the middle of this decade.

These projects would form part of SSE’s £24bn investment programme in the UK, and in addition to supporting the decarbonisation of industrial heartlands and powering a low-carbon future, they would also help to secure a just transition for workers and communities.

The news item then talks about the future.

Now, SSE Thermal has published ‘A vision for the UK’s net zero transition’ which outlines the need for these low-carbon technologies and the potential of carbon capture and hydrogen in providing flexible back-up to renewables.

It also outlines the steps Government should take to facilitate this:

  • Progress the deployment of carbon capture and storage (CCS) and hydrogen infrastructure in a minimum of four industrial areas by 2030.
  • Support first-of-a-kind carbon capture and storage and hydrogen projects to investment decisions before the end of next year.
  • Increase its ambition for power CCS to 7-9GW by 2030, with regular auctions for Dispatchable Power Agreements.
  • Set out a policy ambition for hydrogen in the power sector and a strategy for delivering at least 8GW of hydrogen-capable power stations by 2030.
  • Accelerate the delivery of business models for hydrogen transport and storage infrastructure, to kickstart the hydrogen economy.

These are my thoughts.

Carbon Capture And Use

There is no mention of Carbon Capture And Use, which in my view, should go hand in hand with Carbon Capture And Storage.

  • Sensible uses for carbon dioxide include.
  • Feeding it to plants like tomatoes, flowers, salad vegetables, soft fruit and herbs in greenhouses.
  • Mineral Carbonation International can convert a dirty carbon dioxide stream into building products like blocks and plasterboard.
  • Deep Branch, which is a spin-out from Nottingham University, can use the carbon dioxide to make animal feed.
  • Companies like CarbonCure add controlled amounts of carbon dioxide to ready-mixed concrete to make better concrete and bury carbon dioxide for ever.

Surely, the more carbon dioxide that can be used, the less that needs to be moved to expensive storage.

Note.

  1. There is a lot of carbon dioxide produced in Lincolnshire, where there are a lot of greenhouses.
  2. At least three of these ideas have been developed by quality research in Universities, in the UK, Australia and Canada.
  3. I believe that in the future more uses for carbon dioxide will be developed.

The Government should do the following.

  • Support research on carbon capture.
  • Support Research on finding more uses for carbon dioxide.

Should there be a disposal premium or tax credit paid to companies, for every tonne of carbon dioxide used in their processes? It might accelerate some innovative ideas!

Can We Increase Power CCS to 7-9GW by 2030?

That figure of 7-9 GW, means that around a GW of CCS must be added to power stations every year.

Consider.

If we develop more ways of using the carbon dioxide, this will at least cut the cost of storage.

Can We Deliver At Least 8GW Of Hydrogen-Capable Power Stations By 2030?

Do SSE Thermal mean that these power stations will always run on hydrogen, or that they are gas-fired power stations, that can run on either natural gas of hydrogen?

In ‘A vision for the UK’s net zero transition’, this is said about the hydrogen power stations.

Using low-carbon hydrogen with zero carbon emissions at point of combustion, or blending hydrogen into existing stations.

So if these power stations were fitted with carbon capture and could run on any blend of fuel composed of hydrogen and/or natural gas, they would satisfy our needs for baseload gas-fired power generation.

Hydrogen Production And Storage

SSE’s vision document says this about Hydrogen Production.

Using excess renewables to create carbon-free hydrogen, alongside other forms of low-carbon hydrogen, which can then be stored and used to provide energy when needed.

SSE’s vision document also says this about Hydrogen Storage.

Converting existing underground salt caverns or creating new purpose-built caverns to store hydrogen and underpin the hydrogen economy.

This page on the SSE Thermal web site is entitled Aldbrough Has Storage, where this is said about storing hydrogen at Aldbrough.

In July 2021, SSE Thermal and Equinor announced plans to develop one of the world’s largest hydrogen storage facilities at the Aldbrough site. The facility could be storing low-carbon hydrogen as early as 2028.

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.

From my own experience, I know there is a similar salt structure in Cheshire, which has also been used to store gas.

Earlier, I said, that one of the things, that SSE would like the Government to do is.

Progress the deployment of carbon capture and storage (CCS) and hydrogen infrastructure in a minimum of four industrial areas by 2030.

If Cheshire and Humberside are two sites, where are the other two?

Deciding What Fuel To Use

If you take the Humberside site, it can provide electricity to the grid in three ways.

  • Direct from the offshore and onshore wind farms.
  • Using natural gas in the gas-fired power stations.
  • Using hydrogen in the gas-fired power stations.

SSE might even add a battery to give them a fourth source of power.

In the 1970s, I used dynamic programming with Allied Mills to get the flour mix right in their bread, with respect to quality, cost and what flour was available.

Finance For SSE Thermal Plans

The news item says this.

These projects would form part of SSE’s £24bn investment programme in the UK.

£24bn is not the sort of money you can realise solely from profits or in sock drawers or down sofas, but provided the numbers add up, these sorts of sums can be raised from City institutions.

Conclusion

I like SSE Thermal’s plans.

Plans To Turn Czech Coal Mine Into Storage, Hydrogen And Solar Hub

The title of this post, is the same as that of this article on Power Engineering International.

This is the sub-heading.

Mine is also going to be the site of an experimental greenhouse project called Eden Silesia

This paragraph outlines Eden Silesia.

The site will also be home to an experimental greenhouse project called EDEN Silesia, managed by the Silesian University of Technology and based on the concept of the Eden Project in Cornwall, England.

It does seem that the Czechs are creating a comprehensive facility around a Gravitricity energy store.

This Gravitricity system is only a 4MW/2 MWh system, but there is also this quote from the company.

Future multi-weight systems could have a capacity of 25MWh or more.

If the concept works, this could be imitated in several countries around the world?

‘Czech Sphinx’ Power Plant Intended To Keep Lights On

The title of this post, is the same as that of this article on The Times.

This is the first paragraph.

The businessman known as the “Czech Sphinx” is set to expand his position in Britain’s energy market after securing subsidy contracts to build a new gas-fired power plant and battery storage project.

As I needed to find the answers to particular questions, I looked for and found the original press release on the EP Holdings web site, which is entitled EPH Will Build A New Gas-Fired Power Plant And Battery Storage Facility In The UK At A Cost Of More Than £1 billion.

These statements describe the project.

  • It will be a 1700MW high efficiency H-class CCGT power project and a 299MW 2-hour battery storage project
  • The power station will be built on the site of the former Eggborough coal station in East Yorkshire.

I find this to be the most significant paragraph.

The high efficiency H-class CCGT project will be the single largest flexible generation asset to be commissioned in the UK since 2012, whilst the battery project will also be one of the largest to be built in the UK to date. Given the site’s close proximity to existing National Grid infrastructure and a number of proposed CCUS and hydrogen pipeline routes, under EPUKI’s plans these projects will make a significant contribution to the UK’s energy transition and security for years to come.

This map from OpenRailwayMap, shows the relationship between the Eggborough site and the nearby Drax power station.

Note.

  1. The Eggborough power station site  is in the South-West corner of the map and is identified by the rail loop. which was used to deliver the coal.
  2. The Drax power station site is in the North-East corner of the map and is similarly identified by a rail loop.
  3. There is a high voltage transmission line connecting the two power stations.
  4. As the crow flies is about eight miles between Eggborough and Drax.

This Google Map shows the Eggborough power station site.

Note.

  1. The remains of the eight cooling towers are visible at the North of the site.
  2. The large circular black area in the middle is the coal yard with its rail loop.
  3. It is a large site.

I have looked in detail at the cleared area in the North-West of the site and the pylons of the connection to Drax are still visible.

So it looks like there is still an electrical connection of some sort to the site.

According to Wikipedia, the original coal-fired power station had a nameplate capacity of 1960 MW, so I suspect that a modernised electricity connection to handle the maximum near 2,000 MW of the new station would be possible.

This map shows the Zero Carbon Humber pipeline layout.

Note.

  1. The orange line is a proposed carbon dioxide pipeline
  2. The black line alongside it, is a proposed hydrogen pipeline.
  3. Drax, Keadby and Saltend are power stations.
  4. Keadby and Saltend are gas-fired power stations.
  5. Easington gas terminal is connected to around twenty gas fields in the North Sea.
  6. The terminal imports natural gas from Norway using the Langeled pipeline.
  7. The Rough field has been converted to gas storage and can hold four days supply of natural gas for the UK.
  8. To the North of Hull is the Aldbrough Gas Storage site, which SSE plan to convert to hydrogen storage.

The Eggborough power station site is about eight miles to the South-West of Drax.

I don’t suspect that connecting the Eggborough site to the carbon dioxide, gas and hydrogen pipelines will not be the most challenging of tasks.

So when the press release says.

Given the site’s close proximity to existing National Grid infrastructure and a number of proposed CCUS and hydrogen pipeline routes, under EPUKI’s plans these projects will make a significant contribution to the UK’s energy transition and security for years to come.

The company is not exaggerating.

It appears that carbon dioxide, gas and hydrogen pipelines can be developed and National Grid connections can be reinstated.

Eggborough Will Not Be Alone

From the EP Holdings press release, it appears that the Eggborough power station will be fitted with carbon-capture and will be hydrogen-ready.

This will make it the second power-station in the area to be fitted out in this way, after SSE’s planned Keadby 3, which is described in this page on the SSE web site in this document, which is entitled Keadby 3 Carbon Capture Power Station.

They could also be joined by Keadby Hydrogen power station.

This would mean that zero-carbon power stations in the area could include.

  • Eggborough Gas/Hydrogen – 1700 MW
  • Eggborough Battery – 299 MW
  • Keadby 3 Gas/Hydrogen – 910 MW
  • Keadby Hydrogen – 1800 MW – According to this Equinor press release.

Note.

  1. The Eggborough Battery pushes the total zero-carbon capacity over 4500 MW or 4.5 GW.
  2. The various Dogger Bank wind farms are to have a total capacity of 8 GW within ten years.
  3. The various Hornsea wind farms are to have a total capacity of 5.5 GW in a few years.

I would expect that the zero-carbon power stations would make a good fist of making up the shortfall, when the wind isn’t blowing.

Drax, Keadby 1 And Keadby 2 Power Stations

Consider.

  • Drax has a nameplate capacity of 3.9 GW, of which 2.6 GW is from biomass and the rest is from coal.
  • Keadby 1 has a nameplate capacity of 734 MW.
  • Keadby 2 has a nameplate capacity of 734 MW.

How much of this capacity will be fitted with carbon capture, to provide extra zero-carbon backup to the wind farms?

Green Hydrogen From Surplus Wind Power

At times, there will be an excess of renewable energy.

I suspect, an order for a large electrolyser will be placed soon, so that surplus renewable energy can be used to create green hydrogen.

This will be stored in the two storage facilities, that are being developed in the area; Aldbrough and Rough.

Controlling The Fleet

I am by training a Control Engineer and this fleet can be controlled to provide the electricity output required, so that the carbon-dioxide produced is minimised and the cost is at a level to the agreement of producers and users.

Conclusion

It looks like in excess of 20 GW of reliable zero-carbon energy could be available on Humberside.

I’m sure British Steel would like to by a lot of GWhs to make some green steel at Scunthorpe.

Gravitricity And Czech Firm DIAMO Announce Plans To Cooperate On Full Scale Gravity Energy Store

The title of this post, is the same as that of this article on The Engineer.

This is the sub-heading.

A former coal mine in the Czech Republic could become the first full scale gravity energy store in Europe, according to UK energy storage specialist Gravitricity

This paragraph describes the project.

The agreement will see the two companies seek funding to transform the former decommissioned Darkov deep mine – which is located in the Moravian-Silesian region of the Czech Republic – into a 4MW / 2MWh energy store, capable of powering more than 16,000 homes. According to Gravitricity the system will store energy by lowering and raising a single massive weight suspended in the Darkov mine shaft. The company has also signed a memorandum with VSB Technical University of Ostrava, whose specialist mining expertise will support the implementation of the technology.

Hopefully, the finance won’t be too difficult to find, with perhaps some help from the EU.

The article also describes the potential of Gravitricity, where it says.

  • There could be up 14,000 suitable mines around the world.
  • The Coal Authority believes there could be a hundred suitable shafts in the UK.

It appears Gravitricity may be on its way.

Diversifying A US$200 billion Market: The Alternatives To Li-ion Batteries For Grid-Scale Energy Storage

The title of this post, is the same as that of this article on Energy Storage News.

This is the introductory paragraph.

The global need for grid-scale energy storage will rise rapidly in the coming years as the transition away from fossil fuels accelerates. Energy storage can help meet the need for reliability and resilience on the grid, but lithium-ion is not the only option, writes Oliver Warren of climate and ESG-focused investment bank and advisory group DAI Magister.

Oliver starts by saying we need to ramp up capacity.

According to the International Energy Agency (IEA), to decarbonise electricity globally the world’s energy storage capacity must increase by a factor of 40x+ by 2030, reaching a total of 700 GW, or around 25% of global electricity usage (23,000TWh per annum). For comparison, this would be like swelling the size of the UK’s land to that of the USA.

Similar to how “nobody ever gets fired for buying IBM”, lithium-ion holds a similar place in grid scale electrical storage today.

And just as IBM did in the last decades of the last century, the builders of lithium-ion will fight back.

He then lists the problems of grid-scale lithium-ion batteries.

  • Shortage of cobalt.
  • Toxic and polluting extraction of some much needed metals and rare earths from unstable countries.
  • Lack of capacity to load follow.
  • Limited lifespan.

He does suggest vehicle-to-grid can provide 7TWh of storage by 2030, but it has similar problems to lithium-ion grid scale batteries.

Finally, he covers these what he considers several viable methods of energy storage in detail.

He introduces them with this paragraph.

No single killer application or technology exists to get the job done. Diversification is key with success dependent on the wide-scale adoption of multiple grid-scale energy storage solutions.

Note.

  1. All systems are environmentally-friendly and use readily-available materials like air, water, sea-water, steel and concrete for their systems.
  2. The most exotic materials used are probably in the control computers.
  3. Some systems use readily-available proven turbo-machinery.
  4. Most systems appear to be scalable.
  5. All systems would appear to have a working life measured in decades.
  6. I would expect that most well-educated teenagers could understand how these systems worked.

Only Augwind Energy and Lumenion are new to me.

He finally sums up the economics and the market potential.

Our ability to expand energy storage capacity is one of the most pressing issues that will determine whether this defining ‘transitional’ decade is a success. But we’ll need to invest wisely into the right technologies that get the greatest bang for the buck (in terms of GWh capacity and return on capital) given the limited lifespan of Li-Ion and the decarbonisation of the grid.

At a current capital cost of US$2,000 per kW quoted by the US National Renewable Energy Laboratory (NREL) for 6-hour Li-ion battery storage, the 700GW of capacity needed by 2030 equates to around a US$1.5 trillion market over the coming decade, making it worth nearly US$200 billion a year.

The Energy Storage News article is a comprehensive must read for anyone, who is considering purchasing or investing in energy storage.

I have some further thoughts.

From My Experience Would I Add Any Other Systems?

I would add the following.

  • Form Energy, because its iron-air battery is well-backed financially.
  • Gravitricity, because it can use disused mine shafts to store energy and the world has lots of those.
  • STORE Consortium, because its 3D-printed concrete hemispheres, that store energy using pressurised sea-water can be placed within a wind farm.

I also suspect that someone will come up with an energy storage system based on tidal range.

Finance

When we started Metier Management Systems, finance to breakout from the first initial sales was a problem. We solved the problem with good financial planning and an innovative bank manager who believed us all the way.

David, was a rogue, but he was a rogue on the side of the angels. Long after Metier, he even came to my fiftieth birthday party.

David would have found a way to fund any of these systems, as they tick all the boxes of demonstrated, environmentally-friendly, safe and understandable. They are also likely to be bought by companies, governments and organisations with a high net value, a very respectable reputation and/or large amounts of money.

I also think, that just as we did with the original Artemis project management system, some of these systems can be leased to the operators.

Second-Use Of Systems

Several of these systems could be moved on to a new location, if say they were supporting an industry that failed.

That would surely help the financing of systems.

Coal Sales Could Lose Tens Of Millions For Consumers

The title of this post, is the same as that of this article on The Times.

These two paragraphs outline the story.

A huge stockpile of coal bought for emergency use in power stations this winter is due to be resold at a loss of tens of millions of pounds to consumers.

National Grid funded the procurement of hundreds of thousands of tonnes of coal as part of a deal to keep open five coal-fired units this winter. The estimated £368 million cost of the “winter contingency contracts”, which includes an undisclosed sum for the coal purchases, is being recouped via energy bills.

Note.

  1. None of the coal has been burned, as the weather was warmer than expected,
  2. It is now sitting in various places around the country.
  3. It will probably sell at a loss and there will be transport costs.

I will look at the mathematics of disposal.

Burning Fossil Fuels

On the Internet, I have found these figures.

  • If you burn a kilogram of natural gas you create 15.5 KWh of electricity and 2.75 kilograms of carbon dioxide.
  • If you burn a kilogram of coal you create 2.46 KWh of electricity and 2.38 kilograms of carbon dioxide.

This means that natural gas and coal create 0.18 and 0.97 kilograms of carbon dioxide respectively for every KWh generated.

I believe these figures say, that if we have to use a fossil fuel, gas will be much better than coal for climate change reasons.

The Size Of The Problem

We are talking about 130,000 tonnes of coal for EDF and 400,000 for Drax. Uniper’s figure is not stated. Let’s say they make the coal pile up to 600,000 tonnes.

Burning this pile will generate 1,476,000 KWh or 1.476 GWh of electricity and create 1428,000 tonnes of carbon dioxide.

Effect On Total UK Carbon Dioxide Emissions

According to government figures on the Internet in 2021 we emitted 107.5 million tonnes of carbon dioxide.

Burning all that coal in a year, would add less than 1.5 % to our carbon dioxide emissions. Perhaps we should burn it strategically over a number of years, when there are energy supply problems, as it is after all a crude form of energy storage.

What Would I Do With The Savings?

The money saved on the transport and making loss-making sales could be spent on other ways to save carbon emissions, like converting surplus wind energy into hydrogen and blending it with the gas.

I discussed the mathematics of hydrogen blending in UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025.

If we put 2 % hydrogen in our natural gas, this would save nearly 2.5 million tonnes of carbon dioxide emissions in a year. This figure is much bigger than the 1428,000 tonnes of carbon dioxide, that would be created by burning all the coal.

At a level of 2 %, most appliances, boilers and industrial processes would work without change. But a good service would help.

The Case For Pumped Hydro Storage

The Coire Glas Project

Note that Coire Glas is a pumped storage hydroelectric scheme being developed by SSE Renewables.

  • It is rated at 1.5 GW.
  • It can store 30 GWh of electricity.
  • It is being built in the Highlands of Scotland above Loch Lochy.
  • The estimated construction time will be five to six years.
  • It should be operational for more than 50 years.
  • There is more about the project on this page on the Coire Glas web site.

Exploratory works have started.

The Case For Pumped Hydro Storage

The title of this post, as the same as that of this page on the Coire Glas web site.

This is the sub-heading.

A study by independent researchers from Imperial College London found that investing in 4.5GW of pumped hydro storage, with 90GWh of storage could save up to £690m per year in energy system costs by 2050, as the UK transitions to a net-zero carbon emission system.

And this is the first paragraph.

The report focused on the benefits of new long-duration pumped hydro storage in Scotland, as the current most established long-duration energy storage technology. The benefit of long duration storage compared to short duration batteries is being able to continuously charge up the storage with excess renewables and also discharge power to the grid for several hours or days when wind and solar output is low.

So Coire Glas will provide 1.5GW/30GW, so where will we get the other 3 GW/60GW?

Loch Earba Pumped Hydro

In Gilkes Reveals 900MW Scottish Pumped Storage Plan, I introduced Loch Earba Pumped Hydro.

  • It is rated at 900 MW
  • It can store 33 GWh of electricity.
  • It is being built in the Highlands of Scotland to the East of Fort William.
  • The estimated construction time will be three to four years.
  • It should be operational for more than 50 years.
  • There is more about the project on the Earba Storage web site.

It would appear we could be edging towards the Imperial College target in lumps of about 1GW/30 GWh.

Other Schemes In Scotland

These are other proposed or planned schemes in Scotland.

Balliemeanoch Pumped Hydro

Balliemeanoch Pumped Hydro now has a web site.

The proposed Balliemeanoch pumped hydro scheme will have these characteristics.

  • Output of the power station will be 1.5 GW
  • Available storage could be 45 GWh.

This medium-sized station has a lot of storage.

Corrievarkie Pumped Hydro

Corrievarkie Pumped Hydro now has a web site.

The proposed Corrievarkie pumped hydro scheme will have these characteristics.

  • Output of the power station will be 600 MW
  • Available storage could be 14.5 GWh.

This medium-sized station has a moderate amount of storage.

Loch Kemp Pumped Hydro

I wrote about Loch Kemp Pumped Hydro in Loch Kemp Pumped Hydro, where I said this.

The proposed Loch Kemp pumped hydro scheme will have these characteristics.

  • Loch Kemp will be the upper reservoir.
  • Loch Ness will be the lower reservoir.
  • The power station will be on the banks of Loch Ness.
  • The power station will be designed to fit into the environment.
  • Eight dams will be built to enlarge Loch Kemp.
  • Trees will be planted.
  • Output of the power station will be 300 MW
  • Available storage could be 9 GWh.

The medium-sized station will have almost as much storage capacity as Electric Mountain, but that power station has an output of 1.8 GW.

Red John Pumped Hydro

I wrote about Red John Pumped Hydro in Red John Pumped Storage Hydro Project, where I said this.

I have also found a web site for the project, which is part of the ILI Group web site.

  • The scheme has an output of 450 MW.
  • The storage capacity is 2,800 MWh or 2.8 GWh.
  • The scheme has planning consent.
  • The project is budgeted to cost £550 million.
  • The construction program indicates that the scheme will be completed by the end of 2025.

Not a large scheme, but every little helps.

Proposed Pumped Hydro In Scotland

I have listed these schemes.

Note.

  1. The scheme’s name is linked to their web site.
  2. The two figures are output and storage capacity.

There is a total output of 5.25 GW and a total storage capacity of 134.3 GWh.

Conclusion

If all these schemes are built, Imperial’s targets of an output of 4.5 GW and a storage capacity of 90 GWh will be comfortably exceeded.

Gilkes Reveals 900MW Scottish Pumped Storage Plan

The title of this post, is the same as that of this article on renews.biz.

This is the sub-heading.

Earba project would be ‘largest in the UK’ in terms of energy stored

And this is the introductory paragraph.

Gilkes Energy has unveiled scoping plans for its 900MW Earba Pumped Storage Hydro Project in Scotland.

These are a few more details.

  • It will have a capacity of 33 GWh.
  • Loch a’ Bhealaich Leamhain is proposed to be the upper reservoir.
  • Lochan na h-Earba is proposed to be the lower reservoir.
  • There will be a three kilometre tunnel between the reservoirs.
  • The 900 MW power station will be on the shore of Loch Earba.
  • Construction is expected to take between 3 and 4 years.

This Google Map shows the location of the site.

And this Google Map shows the site.

Note.

  1. Lochan na h-Earba, which will be the lower reservoir is clearly marked, in the North-West corner of the map.
  2. Loch a’ Bhealaich Leamhain, which will be the upper reservoir is in the South-East corner of the map.
  3. Much of Loch a’ Bhealaich Leamhain appears to be frozen, with only a small triangular area of water visible.
  4. There doesn’t seem to be too many roads.
  5. There is a detailed map on the Earba Storage web site.

This looks like it could be extreme construction, at it’s most extreme.

Conclusion

With a power output of 900 MW and a storage capacity of 33 GWh, this pumped storage hydroelectric power station will have the largest storage capacity of any energy storage in the UK.

Rheenergise & University Partners Secure £1M Grant From UK Government

The title of this post, is the same as that of this press release from Reenergise.

This is the sub-heading.

The Department for Energy Security & Net Zero funded research project will identify and test minerals and discarded wastes for use in RheEnergise’s grid scale hydro energy storage system.

And these are the first three paragraphs.

In partnership with the University of Greenwich and the University of Exeter, RheEnergise, the UK company that is developing a new and advanced form of pumped hydro-energy storage, has secured a grant of £1 million funded through the Net Zero Innovation Portfolio (NZIP) as part of the UK Government’s Energy Entrepreneurs Fund. The government grant will fund work to identify and test waste materials that could be used in the high-density fluid (HDF) that is integral to RheEnergise’s grid-scale High-Density Hydro® energy storage system. The HDF is an environmentally benign alternative to water.

RheEnergise’s long duration storage system is low-cost and energy efficient. The fluid used in the system is 2½ times denser than water (similar in viscosity to cream) and is therefore able to provide 2½ times the power and 2½ times the energy when compared to conventional low-density hydro-power systems that rely on water and operate in the Scottish Highlands, Wales and across Europe. It means that RheEnergise can deploy its long duration energy storage system beneath the surface of hills rather than mountains, so opening up massive commercial opportunities in the UK, Europe and further afield.

The research project, funded by the Department for Energy Security & Net Zero’s Energy Entrepreneurs Fund, wants to identify suitable minerals and waste streams which can be recycled into the high-density fluid which can be locally sourced and are lower-cost, rather than having to rely on minerals imported from overseas.

I feel the concept of High-Density Hydro is excellent and will work.

If this research leads to lower costs, that can only help the development and deployment of High-Density Hydro.

Wind Power For 1.2m Homes Is Wasted Because Of Lack Of Storage

The title of this post, is the same as that of this article on the Daily Telegraph.

These two paragraphs outline what happened.

Enough wind power to supply 1.2m homes a day was wasted over winter because there is no capacity to store extra energy generated on gusty days, according to new research.

National Grid’s electricity system operator asked wind turbines which were expected to generate about 1.35 terawatt-hours of electricity between October and January to switch off instead because they were not needed to meet demand at the time, according to the consultancy Stonehaven.

The problem has been flagged up by Rupert Pearce of Highview Power, who in my view could have a solution with their CRYOBatteries.

Pearce is quoted as saying this.

Renewable energy storage is essential to powering a cleaner, cheaper, always-on Britain.

By capturing and storing excess renewable energy, which is now the UK’s cheapest, most secure and most abundant form of energy, we can power Britain’s homes and businesses with renewable green energy, taking millions of tonnes of carbon out of the atmosphere and ending a culture of reliance on expensive foreign imports.

He’s too bloody right! And my experience of mathematical modelling large vessels at ICI in the 1970s, says that Highview Power have one of the sensible solutions to large scale energy storage.
