‘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.
- 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.
- The Drax power station site is in the North-East corner of the map and is similarly identified by a rail loop.
- There is a high voltage transmission line connecting the two power stations.
- As the crow flies is about eight miles between Eggborough and Drax.
This Google Map shows the Eggborough power station site.
Note.
- The remains of the eight cooling towers are visible at the North of the site.
- The large circular black area in the middle is the coal yard with its rail loop.
- 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.
- The orange line is a proposed carbon dioxide pipeline
- The black line alongside it, is a proposed hydrogen pipeline.
- Drax, Keadby and Saltend are power stations.
- Keadby and Saltend are gas-fired power stations.
- Easington gas terminal is connected to around twenty gas fields in the North Sea.
- The terminal imports natural gas from Norway using the Langeled pipeline.
- The Rough field has been converted to gas storage and can hold four days supply of natural gas for the UK.
- 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.
- The Eggborough Battery pushes the total zero-carbon capacity over 4500 MW or 4.5 GW.
- The various Dogger Bank wind farms are to have a total capacity of 8 GW within ten years.
- 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.
Equinor And SSE Eye Green Hydrogen Production For 1.32 GW Dogger Bank D
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
SSE Renewables and Equinor, the developers of the Dogger Bank Wind Farm in the UK, are exploring two options for Dogger Bank D, the fourth wind farm the partners are looking to build as part of the development. These include using Dogger Bank D for electricity that would feed into the UK grid and/or for green hydrogen production.
This says to me, that depending on need, electricity from the Dogger Bank Wind Farms and D in particular, can be distributed in the grid or converted into green hydrogen.
- The article says that the electrolyser could become the UK’s largest green hydrogen project
- There will be plenty of hydrogen storage in the salt caverns at Aldbrough, which can currently store the equivalent of 320 GWh of electricity, It is currently being expanded to be one of the largest hydrogen stores in the world according to this page on the SSE web site.
- There are currently two gas-fired power stations at Keadby and they will in a few years be joined by a third, that will be fitted with carbon-capture and a hydrogen-fueled power station.
The various wind farms, power stations and gas storage on Humberside are growing into a very large zero-carbon power cluster, with an output approaching six GW.
Any shortfall in wind output, could be made-up by using the Keadby 3 gas-fired power station with carbon capture or the Keadby hydrogen power station.
Conclusion
Humberside is getting a cluster of power stations and wind farms, that can produce almost twice the electricity of Hinckley Point C nuclear power station.
SSE Thermal Charts Path To Green Hydrogen Future With First-Of-A-Kind Project
The title of this post, is the same as that of this press release from SSE Thermal.
This is the sub-heading.
SSE Thermal is developing a first-of-a-kind project in the Humber which would unite hydrogen production, storage and power generation in one location by the middle of this decade.
These paragraphs explain the project.
The Aldbrough Hydrogen Pathfinder project will support the evidence base for wider deployment of flexible hydrogen power in the UK’s net zero journey and is a major enabler of SSE Thermal’s wider Humber ambitions.
Located at SSE Thermal and Equinor’s existing Aldbrough Gas Storage site on the East Yorkshire coast, the project is designed to demonstrate the interactions between hydrogen electrolysis, hydrogen cavern storage and 100% hydrogen dispatchable power.
The concept would see green power sourced from grid through Renewable PPAs, in compliance with the Low Carbon Hydrogen Standard. Hydrogen would then be produced via a 35MW electrolyser before being stored in a converted salt cavern and then used in a 100% hydrogen-fired turbine, exporting flexible green power back to grid at times of system need. In future, hydrogen storage will also benefit offtakers in other sectors, for example in industry, heat or transport.
Note.
- The Aldbrough Gas Storage site currently can store the equivalent of 320 GWh of electricity, It is currently being expanded to be one of the largest hydrogen stores in the world according to this page on the SSE web site.
- SSE Thermal are proposing to build a hydrogen-powered power station at Keadby to the South of the Humber. The press release says this power station could have a peak demand of 1,800MW of hydrogen.
- Aldbrough at its current size could keep the Keadby hydrogen-powered power station going for a week. But Aldbrough will be a lot bigger than the current 320 GWh.
- The Hornsea and Dogger Bank wind farms off the coast of East Yorkshire will have a capacity of at least 13.5 GW.
- A 35 MW electrolyser will produce 15.2 tonnes of hydrogen per day.
SSE and Equinor hope to be storing hydrogen by 2025.
Conclusion
It is an enormous project and it will surely grow with more electrolysers and hydrogen-powered power stations.
Landmark CCS Project In Humber Becomes UK’s First To Gain Planning Consent
The title of this post, is the same as that of this news item on the SSE web site.
This is the first paragraph.
SSE Thermal and Equinor’s Keadby 3 Carbon Capture Power Station in the Humber has become the first power CCS project in the UK to receive planning permission.
Note.
- This will be one of four power stations at Keadby with Keadby 1, Keadby 2 and Keadby Hydrogen Power Station.
- Keadby 3 will have a capacity of 910 MW.
- It will capture up to 1,500,000 tonnes of carbon per year.
- It could be operational as early as 2027.
The news item, also says this about SSE’s other power stations and hydrogen storage.
SSE Thermal and Equinor are also collaborating on Peterhead Carbon Capture Power Station in the north-east of Scotland. In addition, they are developing Keadby Hydrogen Power Station, which could be the world’s first large-scale 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could provide vital storage to balance intermittent supply and demand.
This all fits nicely with the proposed strategy I wrote about in Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero.
I think we can expect more new gas-fired power stations with carbon capture to be built by SSE.
Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero
The title of this post, is the same as that of this news item on the SSE web site.
This is the first paragraph.
Building more power carbon capture and storage plants (Power CCS) could significantly accelerate the UK’s plans to decarbonise the GB electricity system on route to net zero, according to new analysis commissioned by SSE.
I am not surprised, as in my time, I have built several production, storage and distribution mathematical models for products and sometimes bringing things forward has beneficial effects.
These three paragraphs summarise the findings.
The UK Government’s proposed emissions reductions from electricity for 2035 could be accelerated to 2030 by combining its 50GW offshore wind ambition with a significant step up in deployment of Power CCS. This would require 7-9GW (equivalent to 10-12 plants) of Power CCS compared to the current commitment of at least one Power CCS plant mid-decade, according to experts at LCP Delta.
Replacing unabated gas with abated Power CCS generation will deliver significant reductions in greenhouse gas emissions. The analysis suggests that adding 7-9GW Power CCS to the UK’s 2030 offshore wind ambition will save an additional 18 million tonnes of CO2 by 2040, by preventing carbon emissions during periods when the sun isn’t shining, and the wind isn’t blowing.
Gas consumption for electricity generation would not significantly increase, given the 7-9GW Power CCS would displace older and less efficient unabated gas power stations already operating and reduce importing unabated gas generation from abroad via the interconnectors. Importantly, Power CCS can provide a safety net to capture emissions from any gas required to keep the lights on in the event of delays to the roll out of renewables or nuclear.
The report is by LCP Delta, who are consultants based in Edinburgh.
The report says this about the transition to hydrogen.
Power CCS also presents significant opportunities to kickstart, then transition to, a hydrogen economy, benefitting from the synergies between CCS and hydrogen, including proximity to large-scale renewable generation and gas storage facilities which can support the production of both electrolytic and CCS-enabled hydrogen.
And this about the reduction in carbon emissions.
The existing renewables ambition and the accelerated Power CCS ambition are expected to save a total of 72 million tonnes of CO2 by 2040 compared to commitments in the UK’s Net Zero Strategy from October 2021.
I don’t think there’s much wrong with this analysis.
But of course the greens will trash it, as it was paid for by SSE.
I have a few thoughts.
Carbon Capture And Use
I believe we will see a great increase in carbon capture and use.
- Carbon dioxide is already an ingredient to make Quorn.
- Carbon dioxide is needed for fizzy drinks.
- Carbon dioxide can be fed to tomatoes, salad plants, herbs and flowers in giant greenhouses.
- Carbon dioxide can be used to make animal and pet food.
- Carbon dioxide can be used to make building products like plasterboard and blocks.
- Carbon dioxide can be added to concrete.
- Carbon dioxide can be used as a refrigerant and in air-conditioning. There are one or two old Victorian systems still working.
Other uses will be developed.
Carbon Capture Will Get More Efficient
Carbon capture from power stations and boilers, that use natural gas is a relatively new process and its capture will surely get better and more efficient in the next few years.
Gas From INTOG
I explain INTOG in What Is INTOG?.
One of INTOG’s aims, is to supply electricity to the oil and gas rigs and platforms in the sea around the UK.
Currently, these rigs and platforms, use some of the gas they produce, in gas turbines to create the electricity they need.
- I have seen reports that ten percent of the gas that comes out of the ground is used in this way.
- Using the gas as fuel creates more carbon dioxide.
Decarbonisation of our oil and gas rigs and platforms, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.
Gas may not be carbon-neutral, but some gas is more carbon-neutral than others.
SSE’s Plans For New Thermal Power Stations
I have taken this from SSE’s news item.
SSE has deliberately chosen to remain invested in the transition of flexible thermal electricity generation due to the key role it plays in a renewables-led, net zero, electricity system and is committed to decarbonising the generation.
Together with Equinor, SSE Thermal is developing two power stations equipped with carbon capture technology. Keadby 3 Carbon Capture Power Station is based in the Humber, the UK’s most carbon-intensive industrial region, while Peterhead Carbon Capture Power Station is located in the North East of Scotland. Combined, the two stations could capture around three million tonnes of CO2 a year.
Studies have shown that Keadby and Peterhead Carbon Capture Power Stations could make a lifetime contribution of £1.2bn each to the UK economy, creating significant economic opportunity in their respective regions. Both will be vital in supporting the huge amount of renewables which will be coming on the system.
SSE Thermal and Equinor are also collaborating on Keadby Hydrogen Power Station, which could be one of the world’s first 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could be one of the world’s largest hydrogen storage facilities.
Note.
- SSE appear to think that gas-fired power stations with carbon capture are an ideal backup to renewables.
- If gas is available and it can be used to generate electricity without emitting any carbon dioxide, then why not?
- Hydrogen is coming.
Things will get better.
Is A Virtuous Circle Developing?
Consider.
- Spare wind electricity is turned into hydrogen using an electrolyser or perhaps some world-changing electro-chemical process.
- The hydrogen is stored in Aldbrough Hydrogen Storage.
- When the wind isn’t blowing, hydrogen is used to backup the wind in Keadby Hydrogen power station.
- The other Keadby power stations can also kick in using natural gas. The carbon dioxide that they produce, would be captured for storage or use.
- Other users, who need to decarbonise, can be supplied with hydrogen from Aldbrough.
Note.
- Gas turbines are throttleable, so if National Grid wants 600 MW to balance the grid, they can supply it.
- As time progresses, some of the gas-fired power stations at Keadby could be converted to hydrogen.
- Rough gas storage is not far away and could either store natural gas or hydrogen.
- Hydrogen might be imported by tanker from places like Africa and Australia, depending on price.
Humberside will be levelling up and leading the decarbonisation of the UK.
If you have an energy-hungry business, you should seriously look at moving to Humberside.
The Lincolnshire Wind Powerhouse
In August 2022, reports started to appear about the Outer Dowsing Wind Farm, like this article on offshoreWIND.biz, which is entitled Corio, Total Submit Scoping Report For 1.5 GW Outer Dowsing Offshore Wind Project.
There is now a web site.
- Outer Dowsing Offshore Wind is a 1.5GW project located approximately 54km off the Lincolnshire coast.
- It is a joint project between TotalEnergies and Corio Generation.
This map from the Outer Dowsing Wind Farm web site, shows the location of the wind farm.
These are the sizes of the various windfarms, that are shown on the map.
- Dudgeon – 402 MW
- Hornsea 1 – 1218 MW
- Hornsea 2 – 1386 MW
- Hornsea 3 – 2852 MW
- Hornsea 4 – 1000 MW – Not shown on map.
- Humber Gateway – 219 MW
- Lincs – 270 MW
- Lynn and Inner Dowsing – 194 MW
- Norfolk Vanguard West – No information, but Norfolk Vanguard is 1800 MW
- Outer Dowsing – 1500 MW
- Race Bank – 580 MW
- Sheringham Shoal – 317 MW
- Sheringham Shoal and Dudgeon Extensions – 719 MW
- Triton Knoll – 857 MW
- Westernmost Rough – 210 MW
Note that these total up to 11724 MW, but with Norfolk Vanguard the total is 135224 MW.
Gas-Fired Power Stations
There are also several active gas-fired power stations.
- Immingham – 1240 MW
- Keadby – 734 MW
- Keadby 2 – 893 MW
- Keadby 3 – 910 MW – Planned to be fitted with carbon capture.
- Saltend – 1200 MW
- South Humber Bank – 1365 MW
- Spalding – 860 MW
- Sutton Bridge – 819 MW
Note that these total up to 8021 MW.
Viking Link
The Viking Link is a 1.4 GW interconnector, that links Bicker Fen in Lincolnshire and Denmark, that should be operational at the end of 2023.
Gas Storage
There are two major gas storage facilities in the rea.
- Aldbrough Gas Storage is formed of salt caverns to the North of the Humber.
- Rough Gas Storage is to the East of the Humber in a depleted gas field.
Both will eventually be converted to store hydrogen, which could be used by local industrial users or the proposed hydrogen power station at Keadby.
SSE Thermal And Equinor To Acquire Triton Power In Acceleration Of Low-Carbon Ambitions
The title of this post, is the same as that as this press release from SSE.
These are the first three paragraphs.
SSE Thermal and Equinor have entered into an agreement to acquire Triton Power Holdings Ltd from Energy Capital Partners for a total consideration of £341m shared equally between the partners.
The transaction represents another step forward for the two companies’ existing collaboration, supporting the long-term decarbonisation of the UK’s power system whilst contributing to security of supply and grid stability through flexible power generation in the shorter term.
Triton Power operates Saltend Power Station which is 1.2GW CCGT (Combined Cycle Gas Turbine) and CHP (Combined Heat & Power) power station located on the north of the Humber Estuary in East Yorkshire.
This deal is more complicated than it looks and these are my thoughts.
What About The Triton Power Workers?
The press release says this.
The 82 existing employees will continue to be employed by Triton Power. In line with just transition principles, the joint venture is committed to transitioning the assets for the net zero world through responsible ownership and operation, and in consultation with the local workforce and representatives.
It does sound that they are following the right principles.
Saltend Power Station
Saltend power station is no tired ancient asset and is described like this in Wikipedia.
The station is run on gas using single shaft 3 × Mitsubishi 701F gas Turbines machines with Alstom 400 MWe generators. The station has a total output of 1,200 MW; of that 100 MW is allocated to supply BP Chemicals. Each gas turbine has a Babcock Borsig Power (BBP) heat recovery steam generator, which all lead to one steam turbine per unit (single shaft machine means Gas turbine and Steam Turbine are on the same shaft). The waste product of electricity generation is steam at the rate of about 120 tonnes/h which is sold to BP Chemicals to use in their process. This makes Salt End one of the most efficient[clarification needed] power stations in the UK. The plant is scheduled to use hydrogen from steam reformed natural gas for 30% of its power.
Note.
- It was commissioned in 2000.
- It appears there are seven CCGT power stations in England that are larger than Saltend.
- The power station seems to have had at least four owners.
The press release says this about SSE and Equinor’s plans for Saltend power station.
The transaction underscores SSE Thermal and Equinor’s shared ambition to decarbonise the Humber, which is the UK’s most carbon-intensive industrial region, as well as the UK more widely. Initial steps to decarbonise Saltend Power Station are already underway, targeting partial abatement by 2027 through blending up to 30% of low-carbon hydrogen. In addition, carbon capture provides an additional valuable option for the site. SSE Thermal and Equinor will continue to work towards 100% abatement.
Note.
- It appears that initially, Saltend power station will move to running on a mixture of 30 % hydrogen and 70 % natural gas.
- Carbon capture will also be applied.
- It looks like that in the future all carbon-dioxide emitted by the power station will be captured and either stored or used.
The press release says this about the source of the hydrogen.
Saltend Power Station is a potential primary offtaker to Equinor’s H2H Saltend hydrogen production project. H2H Saltend is expected to kick-start the wider decarbonisation of the Humber region as part of the East Coast Cluster, one of the UK’s first carbon capture, usage and storage clusters.
H2H Saltend is described in this page on the Equinor web site, which has a title of The First Step To A Zero Carbon Humber, where this is said.
This project represents a bold but practical first step towards delivering the world’s first net zero industrial cluster by 2040. This unparalleled project can play a leading role in the UK’s journey to net zero by 2050, renew the UK’s largest industrial cluster, and unlock technology that will put the UK at the forefront of a global hydrogen economy.
There is also a video.
SSE Thermal And Equinor Low-Carbon Thermal Partnership
This is a section in the press release, where after giving their policy about the workers, it says this about the acquisition of Triton Power.
This acquisition strengthens SSE Thermal and Equinor’s portfolio of joint projects, which bring together expertise in power, natural gas, hydrogen and carbon capture and storage. This portfolio includes three development projects within the Humber region:
- Keadby 3 Carbon Capture Power Station, which could be the UK’s first flexible power station equipped with carbon capture.
- Keadby Hydrogen Power Station, which could be one of the world’s first 100% hydrogen-fuelled power stations.
- Aldbrough Hydrogen Storage, located in East Yorkshire, which could be one of the world’s largest hydrogen storage facilities.
The two companies are also developing Peterhead Carbon Capture Power Station, situated on the Aberdeenshire coast in Scotland and there are further opportunities for hydrogen blending across SSE’s generation portfolio, including at Keadby 2.
Note.
- There is no mention of the three Dogger Bank Wind Farms, each of which will be 1200 MW, that are owned by SSE Renewables and Equinor.
- I wrote about Aldbrough Gas Storage in The Massive Hydrogen Project, That Appears To Be Under The Radar.
- According to this press release from Equinor, which is entitled SSE Thermal And Equinor Join Forces On Plans For First-Of-A-Kind Hydrogen And Carbon Capture Projects In The Humber, Keadby Hydrogen power station will have a capacity of 1800 MW.
The Complete System
The system has the following power sources.
- Dogger Bank A – 1200 MW – Expected commissioning in 2023/24
- Dogger Bank B – 1200 MW – Expected commissioning in 2024/25
- Dogger Bank C – 1200 MW – Expected commissioning in 2024/25
- Keadby power station – 735 MW
- Keadby 2 power station – 893 MW – Could be Part-Hydrogen
- Keadby 3 power station – 910 MW – Carbon Capture
- Keadby Hydrogen power station – 1800 MW – Hydrogen
- Saltend power station – 1200 MW – Part-Hydrogen
That totals up to 9138 MW.
Fuel will come from three sources.
- The God of the winds.
- Natural gas
- Hydrogen
Hydrogen will be sourced from.
- Blue hydrogen from H2H Saltend
- Green Hydrogen could come from electrolysers driven by wind power.
Hydrogen would be stored in Aldbrough Gas Storage.
I am by training a Control Engineer and controlling these power sources is either a wonderful dream or your most entwined and complicated nightmare.
Conclusion
I suspect on an average day, this cluster of power stations and sources could reliably supply as much zero-carbon power as two large nuclear stations.
