Significant Step Forward For Keadby 3 Carbon Capture Power Station

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

These three paragraphs outline the project.

A landmark project in the Humber which could become the UK’s first power station equipped with carbon capture technology has taken a major leap forward following an announcement by the UK Government today.

Keadby 3 Carbon Capture Power Station, which is being jointly developed by SSE Thermal and Equinor, has been selected to be taken forward to the due diligence stage by the Department for Business, Energy and Industry Strategy (BEIS) as part of its Cluster Sequencing Process.

This process will give the project the opportunity to receive government support, allowing it to deploy cutting edge carbon capture technology, and to connect to the shared CO2 pipelines being developed through the East Coast Cluster, with its emissions safely stored under the Southern North Sea. The common infrastructure will also supply low-carbon hydrogen to potential users across the region.

The press release also says this about the power station.

  • Keadby 3 power station could have a generating capacity of up to 910MW.
  • It could be operational by 2027.
  • It would capture up to one and a half million tonnes of CO2 a year.

It would provide low-carbon, flexible power to back-up renewable generation.

The H2H Saltend Project

The press release also says this about the H2H Saltend project.

Equinor’s H2H Saltend project, the ‘kick-starter’ for the wider Zero Carbon Humber ambition, has also been taken to the next stage of the process by BEIS. The planned hydrogen production facility could provide a hydrogen supply to Triton Power’s Saltend Power Station as well as other local industrial users. In June, SSE Thermal and Equinor entered into an agreement to acquire the Triton Power portfolio.

I wrote about H2H Saltend and the acquisition of Triton Power in SSE Thermal And Equinor To Acquire Triton Power In Acceleration Of Low-Carbon Ambitions.

In the related post, I added up all the power stations and wind farms, that are owned by SSE Thermal and it came to a massive 9.1 GW, which should all be available by 2027.

Collaboration Between SSE Thermal And Equinor

The press release also says this about collaboration between SSE Thermal and Equinor.

The two companies are also collaborating on major hydrogen projects in the Humber. Keadby Hydrogen Power Station could be one of the world’s first 100% hydrogen-fuelled power stations, while Aldbrough Hydrogen Storage could be one of the world’s largest hydrogen storage facilities. In addition, they are developing Peterhead Carbon Capture Power Station in Aberdeenshire, which would be a major contributor to decarbonising the Scottish Cluster.

This collaboration doesn’t lack ambition.

I also think, that there will expansion of their ambitions.

Horticulture

Lincolnshire is about horticulture and it is a generally flat county, which makes it ideal for greenhouses.

I wouldn’t be surprised to see a large acreage of greenhouses built close to the Humber carbon dioxide system, so that flowers, salad vegetables, soft fruit, tomatoes and other plants can be grown to absorb the carbon dioxide.

It should also be noted that one of the ingredients of Quorn is carbon dioxide from a fertiliser plant, that also feeds a large tomato greenhouse.

We would have our carbon dioxide and eat it.

Other Uses Of Carbon Dioxide

Storing carbon dioxide in depleted gas fields in the North Sea will probably work, but it’s a bit like putting your rubbish in the shed.

Eventually, you run out of space.

The idea I like comes from an Australian company called Mineral Carbonation International.

We would have our carbon dioxide and live in it.

I also think other major uses will be developed.

A Large Battery

There is the hydrogen storage at Aldbrough, but that is indirect energy storage.

There needs to be a large battery to smooth everything out.

In Highview Power’s Second Commercial System In Yorkshire, I talk about Highview Power’s proposal for a 200MW/2.5GWh CRYOBattery.

This technology would be ideal, as would several other technologies.

Conclusion

Humberside will get a giant zero-carbon power station.

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.

  1. It was commissioned in 2000.
  2. It appears there are seven CCGT power stations in England that are larger than Saltend.
  3. 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.

  1. It appears that initially, Saltend power station will move to running on a mixture of 30 % hydrogen and 70 % natural gas.
  2. Carbon capture will also be applied.
  3. 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.

  1. 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.
  2. I wrote about Aldbrough Gas Storage in The Massive Hydrogen Project, That Appears To Be Under The Radar.
  3. 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.
