Highview Power’s Plan To Add Energy Storage To The UK Power Network

The plan was disclosed in this article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, by Rupert Pearce, who is Highview’s chief executive.

His plan is to build twenty of Highview Power’s CRYOBatteries around the country.

  • Each CRYOBattery will be able to store 30 GWh.
  • Each CRYOBattery will be one of the largest batteries in the world.
  • They will have three times the storage of the pumped storage hydroelectric power station at Dinorwig.
  • They will be able to supply 2.5 GW for twelve hours, which is more output than Sizewell B nuclear power station.

The first 30 GWh CRYOBattery is planned to be operational by late 2024.

  • It will be built on Humberside.
  • Humberside is or will be closely connected to the Dogger Bank, Hornsea and Sofia wind farms.
  • When fully developed, I believe these wind farms could be producing upwards of 8 GW.

The Telegraph quotes Rupert Pearce as saying this.

We can take power when the grid can’t handle it, and fill our tanks with wasted wind (curtailment). At the moment the grid has to pay companies £1bn a year not to produce, which is grotesque.

I certainly agree with what he says about it being a grotesque practice.

It sounds to me, that Rupert’s plan would see Highview Power in the waste electricity management business.

  • The wasted wind would just be switched to the Humberside CRYOBattery, if there was too much power in the area.
  • The CRYOBattery might be conveniently located, where the wind farm cables join the grid.
  • Dogger Bank A and B wind farms are connected to Creyke Beck substation, which is North of the Humber.
  • Hornsea 1 and Hornsea 2 wind farm are connected to Killingholme substation, which is South of the Humber.
  • Hornsea 3 wind farm will be connected to Norfolk.
  • Hornsea 4 wind farms will be connected to Creyke Beck substation
  • It looks like the combined capacity of Dogger Bank A, Dogger Bank B and Hornsea 4 could be around 3.4 GW.
  • Sofia wind farm will be connected to Lazenby substation near Redcar.
  • As the CRYOBattery is buying, selling and storing electricity, I would assume that there’s money to be made.

This Google Map shows Creyke Beck substation.

Note.

  1. It is a large site.
  2. Creyke Beck Storage have built a 49.99 MW lithium-ion storage battery on the site.
  3. The Northern part of the site is used to store caravans.
  4. It looks like the combined capacity of Dogger Bank A, Dogger Bank B and Hornsea 4 could be around 3.4 GW.

It looks like a 30 GWh CRYOBattery with a maximum output of 2.5 GW would be an ideal companion for the three wind farms connected to Creyke Back substation.

The combination could probably supply upwards of 2.5 GW to the grid at all times to provide a strong baseload for Humberside.

Conclusion

Will the income from the Humberside CRYOBattery be used to fund the next CRYOBattery?

I very much think so as it’s very sensible financial management!

Ørsted Awarded Contract For World’s Single Biggest Offshore Wind Farm

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

This is the sub-title.

The UK Department for Business, Energy and Industrial Strategy (BEIS) has awarded Ørsted a contract for difference for its Hornsea 3 offshore wind farm. The project was awarded at an inflation-indexed strike price of GBP 37.35 per MWh in 2012 prices.

And this is the first paragraph, which describes the size of the farm.

With a capacity of 2,852 MW, Hornsea 3 will produce enough low-cost, clean, renewable electricity to power 3.2 million UK homes, making a significant contribution to the UK Government’s ambition of having 50 GW offshore wind in operation by 2030 as part of the British Energy Security Strategy. 

This map from Ørsted shows the location of the Hornsea wind farm and its three sections.

Note.

  1. The Hornsea Wind Farm, when fully developed, with a fourth section, is likely to have a capacity of around six GW.
  2. The Lincs, Race Bank and the Westernmost Rough wind farms are about another GW.

Looking at the map, I can see Humberside hosting the world’s largest hydrogen electrolyser to feed into the Humber Zero hydrogen network.

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 Doggerbank 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.

Eight New Freeports Set To Open In The UK

Today, in his 2021 Budget, Rishi Sunak announced eight new freeports.

This article on the BBC, which is entitled Freeports: What Are They And Where Will They Be?, gives a brief guide to the freeports.

This links link to the nearest I can find to an official web site for each of the freeports.

The Government has said that the freeports will start their operations late this year.

Energy In North-East Lincolnshire

A few weeks ago, I took a train from Doncaster to Cleethorpes and back.

These pictures show the area is all about energy.

Keadby Power Station

Keadby power station is a 734 MW gas-fired power-station, that opened in 1996.

Keadby 2 Power Station

Keadby 2 is described on this page of the sseThermal web site.

These are the three opening paragraphs.

Keadby 2 is a new 840MW gas-fired power station in North Lincolnshire currently being constructed by our EPC contractor Siemens Energy. The project is adjacent to our operational Keadby 1 Power Station.

SSE Thermal has partnered with Siemens Energy to introduce first-of-a-kind, high-efficiency gas-fired generation technology to the UK. When completed, Keadby 2 is expected to become the cleanest and most-efficient gas-fired power station in Europe.

The station will also be capable of being upgraded to further decarbonise its generation through carbon capture or hydrogen technology, as routes to market develop.

Note.

  1. It will be possible to add Carbon Capture and Storage technology to Keadby 2 to make the plant net-zero carbon.
  2. Keadby 2 will be able to run on hydrogen.
  3. Keadby 2 is the under-construction power station in my pictures.

Could this be the prototype gas-fired power station of the future?

Keadby 3 Power Station

Keadby 3 is described on this page of the sseThermal web site.

These are the two opening paragraphs.

SSE Thermal is developing the option for a low-carbon combined cycle gas turbine (CCGT) at our Keadby site in North Lincolnshire, which will be known as Keadby 3.

As part of our commitment to a net zero emissions future, Keadby 3 will only be built with a clear route to decarbonisation, either using hydrogen as a low-carbon fuel, or equipping it with post-combustion carbon capture technology. The project is at the early stages of development and no final investment decision has been made.

Keadby 3 is still in the consultation and planning stage.

This newsletter on the sseThermal web site, gives some useful information about Keadby 3.

These are the first three paragraphs.

We are proposing to build a new gas fired power station at Keadby, North Lincolnshire. The project, known as Keadby 3, will have a generating capacity of up to 910 megawatts (MW) and will provide the essential back up to renewable generation and reliable and flexible energy during the country’s transition to Net Zero.

Keadby 3 will be a highly efficient gas fired power station. It will either use natural gas as the fuel and be fitted with a Carbon Capture Plant (CCP) to remove carbon dioxide (CO2) from the emissions to air from the plant, or it will be fired on primarily hydrogen, with no carbon dioxide emissions to air from its operation. Both options are currently being considered, and government is also currently considering the roles of carbon capture and hydrogen in the power sector nationally.

Keadby 3 will require connections for natural gas and possibly hydrogen fuel, water for use in the process
and for cooling and possibly for a pipeline to export the captured CO2 into a gathering network being provided by others and from there to a permanent geological storage site. An electricity connection to export the generated electricity to the UK transmission system will also be required. The plant would be capable of operating as a dispatchable low-carbon generating station to complement the increasing role of renewables in supplying the UK with electricity

Note.

  1. The three Keadby gas-fired power stations can generate 2484 MW of electricity in total.
  2. By comparison, the under-construction Hinckley Point C nuclear power station will be able to generate 3200 MW.
  3. The addition of a Keadby 4 power station, if it were the same size as Keadby 3, would mean the Keadby cluster of gas-fired power stations had a capacity of 3394 MW and they would be larger than the big nuclear station.

In terms of power output, it is an interesting alternative to a larger nuclear power station.

What About The Carbon?

If you’re burning natural gas, you will produce some carbon dioxide.

Power generation from natural gas creates 0.2 Kg of CO2 per kWh according to this web page.

So a 3000 MW station that produces 3000 MW, will produce 3000 MWh or 3000000 kWh in an hour.

This will create 600,000 Kg or 600 tonnes of carbon dioxide in an hour.

As there are roughly 9000 hours in a year, that is roughly 5.4 million tonnes of carbon dioxide.

This newsletter on the sseThermal web site, gives some information about sseThermal are going to do with the carbon dioxide.

As a low-carbon CCGT, Keadby 3 comprises one high efficiency gas turbine and associated steam turbine and either the infrastructure required to allow the CCGT to fire primarily on hydrogen gas, r inclusion of a post combustion Carbon Capture Plant (CCP) in a scenario where natural gas is used as the fuel. In the latter scenario, this is required in order that CO2 emissions are captured and directed to an offshore geological store through the Humber Low Carbon cluster pipeline network being developed by National Grid Ventures and partners.

A diagram of these components, and optional components, is shown below.

Note.

  1. Click on the image to get a larger view.
  2. The CCGT Power Plant is on the left.
  3. Most of the power is generated by the gas-turbine.
  4. Heat is recovered to create steam, which drives a turbine to create more electricity
  5. The Carbon Capture Plant is on the right.
  6. Carbon dioxide is extracted from the exhaust.

There are two outputs from the plant; electricity and carbon dioxide.

As the carbon dioxide is in a pipe from the drying and compression unit, it is easy to handle.

The newsletter says this about what will happen to the carbon dioxide.

CO2 emissions are captured and directed to an offshore geological store through the Humber Low Carbon cluster pipeline network being developed by National Grid Ventures and partners.

As there are several worked out gas fields in the area, there are places to store the carbon dioxide.

Storing The Carbon Dioxide

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. Easington gas terminal is connected to around twenty gas fields in the North Sea.
  5. The terminal imports natural gas from Norway using the Langeled pipeline.
  6. The Rough field has been converted to gas storage and can hold four days supply of natural gas for the UK.

I can see this network being extended, with some of the depleted gas fields being converted into storage for natural gas, hydrogen or carbon dioxide.

Using The Carbon Dioxide

But I would prefer , that the carbon dioxide were to be put to use. Under Carbon Capture and Utilisation on Wikipedia, a variety of uses are shown.

Surprisingly, they don’t talk about using the carbon dioxide to promote the growing of crops in green houses.

I do think, though, that some clever chemists will find ways to convert the carbon into some form of advanced engineering plastics to replace steel.

Hydrogen-Fuelled Power Stations

Note how on the map the hydrogen pipeline goes through the Keadby cluster of power stations.

  • Hydrogen is a zero-carbon fuel.
  • It will be produced offshore by wind turbines connected to electrolysers.
  • The hydrogen will be brought ashore using the existing gas pipeline network.
  • Excess hydrogen could be stored in the worked out gas fields.

I suspect there will be a massive increase in the number of wind turbines in the North Sea to the East of Hull.

Hydrogen Steelmaking

In ten years time, this will surely be the way steel will be made. British Steel at Scunthorpe would surely be an ideal site.

It would also be an ideal site for the HIsarna steelmaking process, which generates much less carbon dioxide and because it is a continuous process, what carbon dioxide is generated is easily captured.

Conclusion

Installations like this will mean that large nuclear power stations built with Chinese money are not needed.

Funding Award to Supply An 8MW Electrolyser

The title of this post, is the same as that of this Press Release from ITM Power.

This is the main body of the Press Release.

ITM Power, the energy storage and clean fuel company, is pleased to announce it has signed an agreement to supply an 8MW electrolyser in the UK.  The agreement, including associated project costs, has a total value of £10m and funding will fall across FY2021 and FY2022.  Further details will be announced in due course.

I bet they’re pleased!

To get a hold on what 8 MW looks like, these Class 90 locomotive each have a power output of just under 4 MW and are capable of hauling an eight-coach express train at 110 mph.

Working at full rate, the electrolyser will be able in a year to convert 70 GWh of electricity into hydrogen.

Why Would You Want An 8MW Electrolyser?

These are a few ideas.

Green Hydrogen For Humberside

This is a project described in this ITM Power Press Release.

This is the first three paragraphs.

ITM Power, the energy storage and clean fuel company, is pleased to announce that it has won, with partner Element Energy, a first stage deployment project in the UK Government’s Industrial Strategy Challenge Fund competition “Decarbonisation of Industrial Clusters” to assess the feasibility and scope of deploying green hydrogen with some major industrial partners in Humberside.

“Green Hydrogen for Humberside” will lead to the production of renewable hydrogen at the Gigawatt (GW) scale distributed to a mix of industrial energy users in Immingham, Humberside. Decarbonisation of this cluster is critical in reaching the UK’s legally binding 2050 net zero emission targets. Humberside, the UK’s largest cluster by industrial emissions, (12.4Mt of CO2 per year), contributes £18bn to the national economy each year and has access to a large renewable resource from offshore wind in the North Sea.

The project will work with customers in the region to establish the feasibility of switching to renewable hydrogen and justify a number of 100MW deployments of electrolysers. The project will cost the supply of hydrogen to these end users. This includes the electricity supply to the electrolyser, the hydrogen production facility, hydrogen distribution across the Humber and conversion of existing processes to use renewable hydrogen.

The study talks about a number of 100 MW deployments of electrolysers.

Will the 8MW electrolyser be a demonstrator for this project?

To Convert Surplus Renewable Energy Into Hydrogen Which Is Injected Into The Gas Grid

The Wikipedia entry for ITM Power has a section entitled Energy Storage Power To Gas. This is the first paragraph.

Power-to-Gas is a methodology of introducing such hydrogen to the natural gas network, essentially converting renewable electrical power to a clean gas that can be more conveniently stored using existing assets. There are two main Power-to-Gas mechanisms. The first involves metering pressurised hydrogen into the gas network directly. The second involves combining hydrogen with carbon dioxide via a methanation process to produce synthetic natural gas prior to introduction to the grid.

The electrolyser could be used to convert a lot of electricity into zero-carbon hydrogen for use in the UK gas network.

Improving The Resilience Of The UK Gas Network

This article on the BBC is entitled Major Power Failure Affects Homes And Transport and it describes a major power failure, when two generators failed in August 2019.

Could the 8MW electrolyser be part of the solution to make the UK power network more robust, if parts of the network fail?

To Create Feedstock For An Oil Refinery Or Petro-Chemical Plant

Hydrogen can be used as a feedstock for an oil refinery or petro-chemical plant.

This ITM Power Press Release, describes such a project, where wind power from the North Sea is used to create hydrogen for Phillips 66 Limited’s Humber Refinery.

As Part Of An Experimental Steel-Making Plant

This is pure speculation on my part, but steel-making creates lot of carbon-dioxide.

I do believe that using hydrogen to make steel is possible and ITM Power are based in the steel-city of Sheffield.

On the other hand look at the HYBRIT web site.

This is the introductory paragraph.

In 2016, SSAB, LKAB and Vattenfall joined forces to create HYBRIT – an initiative that endeavors to revolutionize steel-making. HYBRIT aims to replace coking coal, traditionally needed for ore-based steel making, with hydrogen. The result will be the world’s first fossil-free steel-making technology, with virtually no carbon footprint.

During 2018, work started on the construction of a pilot plant for fossil-free steel production in Luleå, Sweden. The goal is to have a solution for fossil-free steel by 2035. If successful, HYBRIT means that together we can reduce Sweden’s CO2 emissions by 10% and Finland’s by 7%.

This page on their web site is entitled Steel Making Today And Tomorrow. This image compares traditional blast furnace steelmaking with HYBRIT.

Note that at the heart of the process is the production of hydrogen from renewable electricity. This process will need a large electrolyser.

 

Could someone be doing something similar in Sheffield or more likely, Scunthorpe?

  • British Steel may be owned by the Chinese, but it has a record of innovation.
  • We will need a lot of long steel products, like railway rails and girders, in which British Steel specialise.
  • In a few years, Humberside will have enough renewable electricity from North Sea wind to create an electro-magnetic gun to fire space capsules at Mars.

I will be watching out for hydrogen steelmaking.

Is Jim Ratcliffe Up To Something?

Jim Ratcliffe is a very rich man and the chairman and CEO  of INEOS, which has a turnover of $83billion.

Consider.

  • INEOS must know about hydrogen.
  • I read some years ago, how they were using waste hydrogen to generate electricity on Teesside.
  • I have a feeling that they have backed a hydrogen fuel-cell company.
  • They own the hydrogen factory in Runcorn, where I worked in 1970.
  • They have extensive interests in the North West, North East and Scotland.
  • The company probably has an enormous carbon-footprint, that they’d probably like to reduce, by perhaps using hydrogen instead of natural gas as a feedstock for some processes, like production of ammonia.

But above all the cost of an 8MW electrolyser would be small change and probably cost a lot less, than running the cycling team.

The Fallback

It could of course be used to produce a large amount of hydrogen to power buses, cars and trains.
