Did I See The UK’s Hydrogen-Powered Future In Hull Today?

I went from London to Hull today on Hull Trains for £50.80 return (with my Senior Railcard) to see SSE’s presentation for their Aldbrough Pathfinder Hydrogen project, which will feature a 35 MW green hydrogen electrolyser and 320 GWh of hydrogen storage in the thick layers of salt under East Yorkshire.

  • Green electricity would come mainly from the part-SSE owned 8 GW Dogger Bank wind farm complex.
  • According to their web site, Meld Energy are planning a 100 MW electrolyser, which would produce 13,400 tonnes of hydrogen per year.

Every large helps!

  • It should be noted that the thick layers of salt stretch all the way to Germany, and as drilling and storage technology improves, the amount of hydrogen storage available will increase.
  • I was also impressed by the ambition, competence and enthusiasm, of the SSE engineers that I met.
  • As has been pointed out, HiiROC, who have backing from Centrica, Hyundai, Kia and others, are also in Hull!

I believe, that I saw our hydrogen-powered future in Hull today!

We need more hydrogen mega-projects like these! Perhaps in Aberdeen, Clydeside, Freeport East, Isle of Grain, Merseyside, Milford Haven and Teesside?

SSE Unveils Redevelopment Plans For Sloy Hydro-Electric Power Station

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

These are the two bullet points of the news item.

  • Scotland First Minister Humza Yousaf welcomes plans to convert conventional hydro plant to new, flexible pumped hydro storage facility
  • If approved for delivery Sloy could provide firm, flexible renewable energy for up to 160 hours non-stop, enough to power 90,000 homes for one week

This is the introductory paragraph.

SSE Renewables, as part of SSE plc, has unveiled plans to convert its 152.5MW Sloy Power Station, Britain’s largest conventional hydro power plant, into a new pumped hydro storage facility to bolster energy security and help provide the large-scale and flexible renewable energy back-up needed in a future UK net zero power system.

And this describes the output and storage capacity.

Subject to final design, the converted Sloy scheme would be capable of delivering up to 25GWh of long-duration electricity storage capacity. At the flick of a switch, the converted Sloy scheme could provide firm, flexible renewable energy for up to 160 hours non-stop, enough to power around 90,000 homes for up to one week.

The Loch Sloy Scheme

In A Lower-Cost Pumped Hydro Storage System, I described the Loch Sloy scheme, as it currently exists.

Whilst writing some of the posts recently about pumped storage I came across the Loch Sloy Hydro-Electric Scheme.

This is the introductory sentence in Wikipedia.

The Sloy/Awe Hydro-Electric Scheme is a hydro-electric facility situated between Loch Sloy and Inveruglas on the west bank of Loch Lomond in Scotland.

This page on the Greenage web site gives comprehensive details of the power station and is well worth a read.

This Google Map shows the Lochs Sloy and Lomond.

Note.

  1. Loch Sloy is in the North-West corner of the map.
  2. The page on Greenage says that Loch Sloy can store 14 GWh of electricity
  3. Loch Lomond is the body of water towards the Eastern side of the map.
  4. Inverglas is on the West bank of Loch Lomond to the North of the Loch Lomond Holiday Park, which is indicated by the green arrow with a tent.

This second Google Map shows the power station and Inverglas.

Note.

  1. It is a classic layout for a hydro-electric power station.
  2. In the North West corner of the map is the valve house, which is connected to Loch Sloy by a three kilometre tunnel.
  3. The valve house controls the water flows to the power station by Loch Lomond.
  4. There are four two-metre pipes running down the hill, one for each of the four turbines.
  5. According to the page on Greenage, the power station has three 40 MW turbines and one 32 MW turbine, which gives a total output of 152 MW.
  6. The water discharges into Loch Lomond after doing its work in the power station.

Loch Sloy is the largest conventional hydroelectric power plant in the UK.

The 2010 Plan To Add Pumped Storage To The Loch Sloy Hydro-Electric Scheme

This page on Hydro Review, which is dated the 10th of November 2010, is entitled SSE Gets Government Consent For Sloy Pumped-Storage Hydropower Project.

These are the first paragraph.

SSE Generation Ltd., the wholly owned generation business of Scottish and Southern Energy, has received consent from the Scottish Government to develop a 60-MW pumped-storage hydro project at its existing Sloy hydropower station at Loch Lomond, SSE reported.

Note.

  1. Two 30 MW pumps will be added to the power station to pump water up the hill from Loch Lomond to Loch Sloy.
  2. According to the page on Greenage, if the two pumps worked together for six hours, they would transfer 432,000 m3 of water. Note that a cubic metre of water weighs a tonne.
  3. Water would be transferred, when there was a surplus of energy being generated over the demand.

It would appear to be a simple scheme, as it is just adding two pumps to pump the water up the hill.

  • As pumps rather than pump/turbines as at Foyers are used, there is no corresponding increase in generating capacity.
  • Water also appears to be pumped up to the valve house in the existing pipes.
  • Loch Sloy and Loch Lomond would not need major works to enable the scheme..

The page on Greenage gives the cost at just £40 million.

Originally, the project was supposed to have started in 2012, but as there are environmental problems with the fish, the work has not started.

These problems are detailed on the page on Greenage.

It looks like this scheme would have had an output of 152.5 MW and a storage capacity of 14 GWh.

Expanding Loch Sloy

Yesterday’s press release says this about the proposed capacity of the proposed Loch Sloy pumped storage scheme.

Subject to final design, the converted Sloy scheme would be capable of delivering up to 25GWh of long-duration electricity storage capacity.

This Google Map shows Loch Sloy.

This second Google Map shows the dam at the Southern end.

Note.

  1. Earlier, I said that Loch Sloy can store 14 GWh of electricity.
  2. To be able to store 25 GWh would need a 78 % increase in capacity.

This could be possible to be obtained by enlarging the dam and perhaps reprofiling the banks of the loch.

Expanding Loch Slow Power Station

This Google Map shows the Loch Sloy dam and the power station.

Note.

The dam is in the North-West corner of the map.

The power station is in the South-East corner of the map.

This repeat of the second Google Map shows the power station in more detail.

There appears to be plenty of space for more turbines, pumps and other electrical gubbins.

Building The Scheme

There may be enlarged buildings and extra pipes up the mountain, but hopefully the major problem of digging more tunnels through the rock may be avoided.

For these reasons, it could be a relatively easy construction project costing tens of millions.

The 14 GWh scheme from 2010 was costed at £40 million, so this 25 GWh scheme would probably cost no more than double or £80 million.

Conclusion

This is a sensible and affordable scheme, that provides a lot of energy storage

Gresham House Energy Storage Sets GBP80 Million Fundraise

Gresham House Energy Storage Fund must be doing something right, as similar headlines are used in half-a-dozen places on the Internet and they regularly seem to be raising more money.

But then, as a Graduate Control Engineer and a previous owner of half a finance company, I’ve always thought raising money to build batteries was a good idea.

My only niggle with Gresham House, is that I would have thought by now, they would have put some money into building one of the excellent new technology batteries that are coming through.

The storage fund or some of its employees, may of course have contributed to some of the crowdfunding for these new technologies, all of which I feel have a good chance of being a success.

Note.

  1. Energy Dome is Italian and all the others are at least fifty percent British.
  2. Most of the British batteries have had backing from the UK government.
  3. All these batteries are environmentally-friendly.
  4. None of these batteries use large quantities of rare and expensive materials.
  5. Energy Dome even uses carbon dioxide as the energy storage medium.

In addition, in Scotland, there is traditional pumped storage hydro-electricity.

Project Iliad

This article on renews.biz has a slightly different headline of Gresham House To Raise £80m For US Battery Buildout.

This is the first two paragraphs.

Gresham House Energy Storage Fund is seeking to raise £80m through a share placing.

The new equity raised will primarily be used to finance 160MW of solar with co-located four-hour battery projects in California, US, known as Project Iliad.

The article then gives a lot of financial details of Project Iliad and Gresham House.

Will Gresham House be backing co-located solar/battery projects in the UK?

  • In Cleve Hill Solar Park, I write about a co-located solar/battery project in Kent.
  • This press release from National Grid is entitled UK’s First Transmission-Connected Solar Farm Goes Live, which also describes a co-located solar/battery project, being built near Bristol.

These two projects are certainly serious and could be pathfinders for a whole host of co-located solar/battery projects.

WillGresham House back some of this new generation?

SSE Renewables Announces Construction Of Second Utility-Scale Battery Storage System

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

These three paragraphs outline the project and its current status.

SSE Renewables has taken a Final Investment Decision to proceed with, and entered into contracts to deliver, its second battery energy storage system (BESS). The 150MW project is located at the site of SSE’s former Ferrybridge coal-fired power station in West Yorkshire, England.

The investment is part of SSE’s £12.5bn Net Zero Acceleration Programme and means construction will now commence later this month at the iconic site.

For decades the Ferrybridge coal-fired power station was a prominent feature of the West Yorkshire landscape, before being decommissioned by SSE in 2016. Now SSE Renewables’ plans to build a new 150MW battery storage project at Ferrybridge will provide flexible generation for Britain’s national grid and a new era for the site.

This Google Map shows the site.

Note.

  1. The A1(M) runs up the West side of the map, with the East Coast Main Line going up the East.
  2. The circular structures in the middle of the map appear to be the bases and remains of the eight cooling towers.
  3. There are a lot of labels saying Ferrybridge power station.
  4. One existing and one demolished sub-stations can be located.
  5. The last Ferrybridge power station; C had a capacity of just over 2 GW.

The Wikipedia entry for Ferrybridge C, is worth a read, as it details the struggles of various owners and their engineers to generate electricity efficiently and with regard to the regulations.

The site’s use since 2016 seems to have been varied with two multi-fuel power stations, that were designed to burn mixed fuel including biomass, general waste and waste wood, a carbon capture experiment for Chris Huhne and now the 150 MW battery, which other sources give as having a storage capacity of 300 MWh.

It looks to me that SSE still own the large site and I wonder what their plans envisage for the site.

  • A large electrolyser to produce hydrogen could be invaluable for decarbonising the heavy industry in the area.
  • According to Wikipedia, there was a plan to build the gas-fired Ferrybridge D and a gas pipeline to connect it to the gas transmission system, but neither were built.
  • So could the gas pipeline be built to distribute the hydrogen?
  • Or could a large hydrogen store and a small hydrogen-powered power-station be built at Ferrybridge to back up the renewables
  • Alternatively, more batteries could be added to the site.

The size of the site, gives lots of possibilities.

ESB, Irish Port Team Up To Make Shannon Estuary Go-To Place For Floating Wind

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

This is the sub-heading.

Irish energy company ESB and Shannon Foynes Port, the company with statutory jurisdiction over all marine activities on the Shannon Estuary, have entered into a collaboration to develop the region into a centre for the deployment of floating offshore wind projects in both Irish and international waters.

This is the introductory paragraph.

Back in 2021, ESB and its then-partner Equinor announced the development of the 1.4 GW Moneypoint floating wind farm in Ireland, with a broader plan under its Green Atlantic @ Moneypoint project to transform the Moneypoint power station in County Clare into a green energy hub and to support wider plans of Shannon Foynes Port to help make the Shannon Estuary a focal point for the offshore wind industry in Europe.

This Google Map shows the location of Moneypoint power station with respect to the Shannon Estuary.

Note.

  1. Moneypoint power station, which is indicated by the red arrow is on the River Shannon.
  2. The city pf Limerick is to the East of Moneypoint.
  3. There’s certainly a lot of water in the West for floating wind turbines.

This second Google Map shows a close-up of the power station.

This is a shortened version of the first paragraph of the Wikipedia entry for the power station.

Moneypoint power station is Ireland’s largest electricity generation station (output 915 MW) and only coal-fired power station. Commissioned between 1985 and 1987, it is located on the River Shannon near Kilrush, County Clare. It was constructed at a cost of more than £700m in one of the largest capital projects in the history of the state. The station operates largely on coal, making it both unique in the context of Irish electricity production and the country’s single largest emitter of greenhouse gases. It is capable of meeting around 25% of customer demand across the country. It has two Heavy Fuel Oil (HFO) storage tanks with a capacity of 50,000 tonnes which can be used as a back-up fuel if required.

In some ways, the only good things about this power station are the grid connection that can handle most of a GW and the large site, which could be used for a variety of energy-related purposes, like green hydrogen generation and storage.

In Shannon Estuary Could Support Build-Out of 30 GW Of Floating Wind, House 2 GW of Electrolysis Capacity, I wrote about the potential of this area.

Those figures of 30 GW of floating wind ans 2 GW of electrolysers will certainly mean a lot of investment going into Moneypoint!

I would also feel, that Moneypoint will need a lot of energy storage to support and balance the grid.

Boralex Commissions BESS At Wind Farm In France In EU-Supported Demonstration Project

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

These two paragraphs outline the project.

Canada-based renewable energy firm Boralex has turned on a 3.3MWh battery storage unit attached to a wind farm in France.

The battery storage project has been installed at the site of the Plouguin wind farm, an 8MW generating facility in the Finistere department of Brittany, northwest France.

Note.

  1. The project was co-financed by the European Union through its European Regional Development Fund (ERDF).
  2. The project was launched to demonstrate the technical feasibility of a hybrid wind-plus-storage project.
  3. Boralex added in its announcement that the project will contribute to the stability of the French electricity grid.

There will be a lot of projects like this in the future.

This paragraph makes an interesting point about using batteries with solar and wind power.

Wind farms are less frequently hybridised with energy storage than solar PV because of the larger minimum project size and less predictable variability, with sharper peaks meaning heavier battery cycling and potentially faster degradation.

My control engineering knowledge and experience says that larger power sources and those that are highly variable will need batteries with more capacity for the same stability and quality of power output.

This sounds to me like a very good reason for developing larger and more affordable batteries, like those of Cheesecake Energy, Energy Dome, Gravitricity and Highview Power.

It also probably means that to stabilise several gigawatts of wind power, you need a very large amount of storage, that can only be provided by pumped storage hydroelectricity.

Conclusion

A very large amount energy storage is going to be needed.

Projects like these are essential to make sure we use them to their full possibilities.

Italy’s Energy Dome Raises $44 million To Focus On CO2 Storage In US

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

This is the opening paragraph.

Energy Dome, an Italian startup focusing on CO2 energy storage solutions, said on Friday it had raised 40 million euros ($44 million) from investors to fund expansion in the U.S.

It looks like another European company chasing Biden’s dollars.

Quinbrook Breaks Ground On ‘Largest’ Solar And Storage Project In The UK

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

These three paragraphs outline the project.

Quinbrook Infrastructure Partners has started construction on Cleve Hill Solar Park, the largest solar and energy storage project in the UK, it claimed.

The specialist global investment manager revealed the Kent-based project, which consists of 373MW of solar and “more than” 150MW of battery energy storage, is expected to be fully completed by the end of 2024.

Once complete, Cleve Hill Solar Park will consist of 880,000 solar panels and battery storage. It was granted development consent by the energy secretary in May 2020.

It is my view, as a Control Engineer, that all solar farms and wind farms should be paired with an appropriately-sized energy storage device.

If this project works out well, we should repeat it on other solar farms of a similar size.

Gravity-Based Green Energy Storage Tech Pioneer Eyes US Mineshafts

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

This is the sub-heading.

Gravitricity and IEA Infrastructure Construction to seek funding under government scheme for projects at ex-mining sites.

These are the first two paragraphs.

A pioneer in gravity-based energy storage technology aims to make its US debut after linking with a major American construction group.

Gravitricity, which uses giant weights hung in deep shafts to store energy, will partner with IEA Infrastructure Construction to jointly seek US funding for projects at former mines.

I wonder how many other companies will go chasing the money, that President Biden has put on offer in the US?

UK Government Grants £30 Million For Long Duration Energy Storage Projects

The title of this post, is the same as that of this article on Solar Power Portal.

These two paragraphs outline the grants and their recipients.

The UK Department for Energy Security and Net Zero (DESNZ) is providing £30 million in grants for three long-duration energy storage (LDES) projects using novel energy storage technologies.

The three projects awarded funding are from Synchrostor, Invinity Energy Systems and Cheesecake Energy. Synchrostor and Cheesecake Energy are to receive £9.4 million each to fund thermal energy storage systems and Invinity Energy Systems receiving £11 million to develop a vanadium flow battery.

The UK Government seems to give out a lot of these grants for research and development purposes and from feedback I have received from recipients and also by applying my own experience, I am of the opinion, that they are spending tax-payers money more in a wise, rather than a foolish direction.

Cheesecake Energy

I wrote about Cheesecake Energy’s grant in Cheesecake Energy Collects £9.4m Government Funding.

The Government’s press release says this about Cheesecake’s grant.

Cheesecake Energy Ltd, Nottingham, which will receive £9.4 million to test their FlexiTanker technology which stores electricity using a combination of thermal and compressed air energy storage and uses a reversible air compression / expansion train to charge and discharge. They will then install pilot units at 2 sites within a microgrid development in Colchester.

If this project proves successful, it surely is one that can be duplicated in many places.

I have had my eye on Cheesecake Energy for some time and this could be their breakthrough.

Invinity Energy Systems

I first wrote about Invinity Energy Systems in UK’s Pivot Power Sees First Battery On Line By 2021.

The Government’s press release says this about Invinity’s grant.

Invinity Energy (UK) Limited, Scotland, which will receive £11 million to develop and manufacture their 7MW, 30MWh 4-hour Vanadium Flow Battery (VFB), the largest in the UK. Invinity will manufacture the 30 MWh VFB at the Company’s factory in West Lothian, Scotland. The location of the plant will be confirmed in due course.

In this article on renews.biz, which is entitled Invinity Wins Funds For 30MWh UK Battery, these two paragraphs introduce the project.

Invinity Energy Systems plc has today been awarded £11m in funding by the Department for Energy Security and Net Zero to build what it says is the largest grid-scale battery ever manufactured in the UK.

The £11m in funding will come from the Longer Duration Energy Storage Demonstration (LODES) Competition, with funding matched by Invinity’s, as yet unnamed, project partner.

These are other points from the article.

  • It will be a fast-response 30MWh battery.
  • The battery will be assembled at Bathgate in Scotland.
  • It will operate as a stand-alone energy storage asset.
  • It will be connected to the National Grid.
  • Invinity’s vanadium flow batteries are an alternative to lithium-ion.

The aim is to go live by 2025.

This paragraph indicates the differences between a vanadium flow battery and a traditional lithium ion one.

Invinity said this battery is safer as they cannot catch fire, more durable as they do not degrade with use and are almost completely recyclable at the end of their 25+ year life, reducing environmental impacts and disposal costs for project owners.

I believe that there will come a point, when fully-developed vanadium flow batteries, will become very attractive for financial reasons to the successful energy storage funds like Gresham House and Gore Street.

If the UK government’s funding hastens the day, when energy storage funds feel that these new-fangled vanadium flow batteries are a safe investment, then it is money well spent.

It is not as though the money is going to an early start-up, as this page on the Invinity Energy Systems web site indicates  at least a dozen installations.

This project for an as yet unnamed customer, which has a capacity of 30 MWh, is probably much bigger and the Government help is probably very much welcomed.

SynchroStor

SynchroStor was new to me, today.

The Government’s press release says this about SynchroStor’s grant.

Synchrostor, Edinburgh, Scotland, which will receive £9.4 million to build a Pumped Thermal Energy Storage (PTES) grid-connected demonstration plant operating at 1MW, with the ability to charge and discharge for a period of 10 hours, longer than current battery technology.

This page named Technology on their web site, explains their technology, both with words and diagrams.

It is probably the most complex technologies of the three batteries, but I don’t think that will be a problem.

Conclusion

The Government has given grants to three different storage technologies.

If all goes well three good sizable pilot plants will be created and those companies like Centrica, Gore Street, Gresham House, National Grid, Ørsted, SSE and others, will be able to judge, which system is best for their needs.
