Centrica Set For Solar Boost With Acquisition Of Two Projects In South-West England
The title of this post, is the same as that of this press release from Centrica.
These three bullet points act as sub-headings.
- Two green energy schemes adding 32MW of solar and battery capacity – enough to power 7,800 homes per year
- Site in Dorset sees construction of a 16MW solar farm and 3MW of battery storage, with a second operational site in Wiltshire adding 13MW of solar capacity
- Investment part of Centrica’s £4bn green-focused investment plan by 2028
These four paragraphs give more details of the Dorset site.
In Dorset, the business has acquired development rights for the construction of a 16MW solar farm and 3MW battery storage plant near Winterborne Whitechurch.
The project breaks ground in early 2024, with the first power exported to the grid in 2025.
The site at Winterborne Whitechurch will be a co-located asset, with the solar farm and battery storage facilities using the same connection point to the grid, helping to maximise the grid connection.
The site is able to power 4,600 homes a year, supported by the battery that can deliver two-hours of energy for a similar number of properties.
But this is no bog-standard wind farm with an attached battery.
This web site introduces Blandford Hill Eco Hub.
This is the second paragraph on the web site’s home page.
The Blandford Hill Eco Hub project consists of an electric vehicle (EV) charging station, a 15 megawatt ground-mounted solar farm and a 3 megawatt battery storage faciality on land south of the A354 at Blandford Hill, Winterborne Whitechurch near Blandford Forum in Dorset. By combining green electricity generation, storage and charging, we’re maximising the green potential with charging for up to 19 EVs at a time.
Note.
- It’s rather a coincidence that the solar farm and battery are almost the same size to those in Centrica’s acquisition.
- The site appears to have been developed by a company called the Pegasus Group, that has used the trade name of Naturalis.
- It does look to me, that Centrica have bought this electric vehicle service station site.
- Centrica get a site to charge nineteen EVs at a time, with its own solar farm and battery.
- The location close to the village means that staff from the village could walk or cycle to work.
- All plans and planning permissions have been thought through and obtained.
- The site even has a dog-walking area, so you can walk the dog, whilst charging your car.
Perhaps, Centrica have a plan to roll out lots of electric vehicle service stations and it was cheaper to buy a innovative prototype, than do the research themselves?
Pegasus Group do seem to design quality projects.
This Google Map shows the location of the site.
Note.
- The village is Winterborne Whitechurch.
- The road going South-West and North-East is the A354 road, which runs between Dorchester in the South-West and Blandford Forum in the North-East.
- The electric vehicle service station appears to be in the large field to the South of the A 354.
It looks like the service station meets the three most important properties of a development; location, location and location.
Could This Site Be Updated To Hydrogen?
Consider.
- Centrica have a substantial interest in a company called HiiROC, who use a technique called plasma electrolysis to extract hydrogen from any hydrocarbon gas.
- The HiiROC process could be used to extract hydrogen from methane, where there is a reliable electricity supply.
- If Winterborne Whitechurch is connected to the gas grid, then I’m certain, that a HiiROC system connected to the solar farm/battery system should be able to fuel passing hydrogen-powered vehicles.
Updates like this could see hydrogen-powered vehicles finally increase their market share.
The Second Site In Wiltshire
This paragraph details the Wiltshire site.
In addition, the business has also acquired the operational Roundponds Solar Farm in Wiltshire. The 13MW solar farm was commissioned in 2015 and is capable of providing energy for around 3,200 homes every year.
This looks like one of those investments, where big companies let small companies get all the permissions and build the asset, before they buy it.
Conclusion
These two projects fit into Centrica’s future development plan.
The last paragraphs, gives a few details of some of Centrica’s new assets.
The Winterborne and Roundponds projects will contribute towards Centrica’s long-term plan to deliver a portfolio of green energy transition assets. They follow the construction of an 18MW solar farm at Codford, Wiltshire which was commissioned in 2023 and a 20MW hydrogen-ready gas-fired peaking plant in Worcestershire. In addition, Centrica is delivering a 50MW battery storage project in Brigg, Lincolnshire, which is nearing completion.
It will be interesting to see what other assets Centrica acquire in the next couple of years.
National Gas To Trial Gravitricity’s H2 Storage Solution
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
Gravitricity’s H2FlexiStore system for underground hydrogen storage could see a pilot built in 2025 after National Gas secured Ofgem funding to explore the technology.
There is then a graphic, which gives a good visual explanation.
The patented system uses lined geological shafts to store up to 100 tonnes of pressurised hydrogen at 220 bar, equivalent to about 3.33GWh of energy. Unlike natural storage such as salt caverns and disused gas fields, the shafts can be sited anywhere. Gravitricity has previously stated its preference for co-locating the storage near to renewable generation and potential major consumers of hydrogen such as heavy industry.
I can see that this simple system can have a lot of diverse uses.
In Centrica Completes Work On 20MW Hydrogen-Ready Peaker In Redditch, I talked about how Centrica had refurbished a decommissioned peaker plant.
One of these stores would keep a 20 MW peaker plant running for a week.
It would also work well with a HiiROC hydrogen system.
Hydrogen Start-Up Can Expand Thanks To Northern Powerhouse Fund
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Suiso’s technology for extracting clean fuel has been found to produce lower emissions and use less energy than common alternatives
These three paragraphs describe the finances and outline the their hydrogen generator.
Suiso, a South Yorkshire-based company developing a hydrogen generator, has raised £3 million from the Northern Powerhouse Investment Fund (NPIF).
The company plans to create generators as big as shipping containers that could power factories, hospitals and warehouses or be used at filling stations to fuel hydrogen-powered vehicles.
The new funds come from the asset manager Mercia’s equity finance fund, which is part of the NPIF, and Mercia’s enterprise investment scheme.
This paragraph describes the technology.
Suiso uses novel microwave technology to extract hydrogen from natural gas or biogas, capturing the carbon in the form of carbon black, which can be used to make tyres, batteries and inks. In 2023 the company was one of the winners of a government competition to provide technology to supply hydrogen energy.
These are my thoughts.
Suiso And HiiROC
Suiso are taking a similar route to HiiROC.
- The base feedstock is natural gas, which is mainly methane or CH4, with four planet-saving hydrogen atoms and a very naughty carbon one.
- Clever technology is then applied to the methane atoms and the carbon atom doesn’t like it, so they let go of the hydrogen atoms.
- It is then a matter of physically separating the carbon black from the hydrogen.
The difference between the two processes is that Suiso use microwave technology and HiiROC use plasma technology.
HiiROC claim their process will work with any hydrocarbon gas from biomethane through off-gas from a chemical plant to natural gas.
So I suspect, that as Suiso says it will work with biomethane, both technologies will work with virtually any hydrocarbon gas.
Uses Of Carbon Black
This Wikipedia entry gives a lot of information on carbon black.
There is a section, which is entitled Common Uses, where this is said.
The most common use (70%) of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Its low cost makes it a common addition to cathodes and anodes and is considered a safe replacement to lithium metal in lithium-ion batteries. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The remaining 10% use of carbon black comes from pigment in inks, coatings, and plastics, as well as being used as a conductive additive in lithium-ion batteries.
Carbon black is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade. Carbon black particles are also employed in some radar absorbent materials, in photocopier and laser printer toner, and in other inks and paints. The high tinting strength and stability of carbon black has also provided use in coloring of resins and films. Carbon black has been used in various applications for electronics. A good conductor of electricity, carbon black is used as a filler mixed in plastics, elastomer, films, adhesives, and paints. It is used as an antistatic additive agent in automobile fuel caps and pipes.
There is another section, which is entitled Use in Lithium-Ion Batteries, where this is said.
Carbon black is a common conductive additive for lithium ion batteries as they have small particle sizes and large specific surface areas (SSA) which allow for the additive to be well distributed throughout the cathode or anode in addition to being cheap and long-lasting. Unlike graphite, which is one of the other common materials used in chargeable batteries, carbon black consists of crystal lattices that are further apart and promotes Li+ intercalation because it allows more pathways for lithium storage.
Carbon black has a low density that allows for a large volume of it to be dispersed so that its conductive effects are applied evenly throughout the battery. Furthermore, its arrangement of randomly distributed graphite-like crystals improves battery stability because of the decrease in the potential barrier of lithium intercalation into graphite, which ultimately affects the performance of cathodes.
Carbon black does seem to be very useful.
Suiso’s Web Site
This is Suiso’s web site.
The page is headed About Us and this is said.
Suiso is a developer of a low energy near zero emission microwave-driven methane cracking process for onsite generation of Hydrogen.
Hydrogen, the most abundant element in the universe, is rapidly emerging as a sustainable solution for the decarbonisation of the economy and a key piece of the energy transition picture in UK, Europe and around the world.
The cost and practical issues with generating and distributing Hydrogen has held back its use in most economies. Suiso’s technology uses existing electrical, natural/bio gas assets and infrastructure to produce clean low cost hydrogen. By transforming stranded ‘brown’ assets into vital hydrogen infrastructure, Suiso helps reduce CO2 emissions and enables countries throughout the world to meet challenging greenhouse gas emissions targets, quickly and cost effectively.
Suiso’s technology allows its generating units to be positioned anywhere there is a supply of natural/bio gas and electricity. Being located at the point of use eliminates the costly distribution (by truck or pipe) of H2 to the customer – delivering significant cost reductions. This allows it to offer competitively priced H2 for small to medium sized applications in developed and developing countries., including:
- H2 Fueling stations
- Biomethane (H2) conversion/decarbonisation for grid injection
- Light industrial applications
- Domestic H2 supply for small communities/towns
- Demand management/System top up
- Emergency H2 supply
It will design, build and supply these generators directly or via licensees to markets throughout the world.
Conclusion
I like this company.
Centrica Completes Work On 20MW Hydrogen-Ready Peaker In Redditch
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Construction is complete on Centrica’s new 20MW hydrogen-blend-ready gas-fired peaking plant in Worcestershire, transforming the previously decommissioned Redditch power plant.
These paragraphs give more details of the project.
The plant is designed to support times of high or peak demand for electricity. Peaking plants only operate when production from renewables can’t meet demand, supporting the energy transition by maintaining a stable electricity supply. The Redditch site can power the equivalent of 2,000 homes for a full day, helping to maintain stability and reliability on the grid.
The plant is capable of using a blend of natural gas and hydrogen, futureproofing the site and supporting the UK’s transition towards a decarbonised energy system.
The Redditch peaking plant forms part of Centrica’s plans to invest between £600m – £800m a year until 2028 in renewable generation, security of supply, and its customers, including building out a portfolio of flexible energy assets. That includes the redevelopment of several legacy power stations, including the Brigg Energy Park in to a power generation and battery storage asset, and the first power station in the UK to be part-fuelled by hydrogen.
I also wrote Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, about this project.
HiiROC
I wonder if this power station will be fitted with a HiiROC system, which will split the natural gas into two useful products; hydrogen and carbon black.
I wrote about HiiROC in Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant.
I can see lots of HiiROC systems creating a hydrogen feed, to decarbonise various processes.
Whose Engines Are Used At Redditch?
Centrica still haven’t disclosed, whose engines they are using.
Centrica Business Solutions Delivers Significant Energy Savings For The Pirbright Institute
The title of this post, is the same as that of this press release from Centrica.
These three paragraphs outline the project.
Centrica Business Solutions has partnered with The Pirbright Institute to deliver sustainable on-site technology that will help reduce its net energy use by more than 10 per cent by 2026.
Centrica installed a new Combined Heat and Power Plant (CHP), which will provide around 75 per cent of Pirbright’s future power needs. The CHP uses natural gas to generate electricity and hot water at the site, with its exhaust gases also used to feed into a heat recovery generator to provide steam. It means CHP technology is over twice as efficient as conventional power sources and can lower organisational reliance on the Grid.
The Institute, which is dedicated to the study of infectious diseases of farm animals, has already devised an energy plan which has introduced energy-saving upgrades across the Surrey campus, including the closure of energy-inefficient buildings, the introduction of efficient lighting and a programme to raise staff awareness of energy consumption.
The system is still powered by natural gas.
Liverpool University
I was an undergraduate at Liverpool University and according to this page on their web site, which is entitled Sustainability, they seem to be following a similar route to the Pirbright Institute.
With a heading of Energy And Carbon, this is the mission statement.
The University’s ambition is to be a climate-resilient campus, that has minimal negative and maximum positive environmental impact, achieving net zero carbon by 2035. We monitor energy and carbon across the entire University as part of the Climate plan and in support of the Sustainability Strategy and Strategy2026 net zero carbon targets.
One section of the page has a title of The Green Recovery with Clarke Energy at the University’s Energy Centre, where this is said.
The University of Liverpool generates up to 90% of its campuses electricity needs on site in the Energy Centre, through CHP. Clarke Energy help the University operate CHP in the most efficient way, keeping us on track with technological developments, such as how the CHP can be adapted to take different fuel blends.
Although there is a nod to different fuel blends, I suspect that the system, like that at Pirbright, is currently powered by natural gas.
Clarke Energy, is headquartered in Liverpool and is a division of Kohler.
Centrica And HiiROC
CHP systems are becoming more common and like these two systems, they are generally powered by natural gas.
In Plans Submitted For Hydrogen Pilot Plant At Humber Power Station, I describe how Hull-based start-up; HiiROC are going to help fuel a gas-fired power station with a hydrogen blend.
This is a paragraph from this article on Business Live, which describes Centrica’s relationship with HiiROC.
It comes as the owner of British Gas has also increased its shareholding in the three-year-old business to five per cent. Last November it was one of several investors to pump £28 million into HiiRoc alongside Melrose Industries, HydrogenOne, Cemex, Hyundai and Kia, who joined existing strategic investors Wintershall Dea and VNG.
HiiROC’s system can take any hydrocarbon gas from biomethane, through chemical plant waste gas to natural gas and convert it to hydrogen and carbon black.
Carbon black has a large number of manufacturing uses and can also be used in agriculture to improve soil.
It looks to me, that HiiROC’s systems will be a simple way to convert natural gas-powered CHPs to zero carbon.
Centrica’s Rough Storage Facility Pumps Gas Into Grid To Meet Increased Demand
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
The UK’s largest gas storage facility, Rough, has released stored gas into the grid to help the UK both manage higher heating demand during the current cold weather and keep prices down. This is the first time Rough has released gas this winter.
These three paragraphs describe how Centrica are using Rough and how they will use it in the future.
This year, Centrica has filled Rough with the equivalent of 18 LNG tankers. Rough provides enough energy to heat over 3 million homes, every day, all winter, keeping families warm and bills down.
Rough is the UK’s largest gas storage facility. It stopped storing gas in 2017 but was re-opened for gas storage in October 2022, and its capacity was doubled in the summer of 2023. The facility, which is 18 miles off the coast of East Yorkshire, now provides half of the UK’s total gas storage.
Centrica’s long-term ambition is to turn the Rough gas field into the largest long duration low carbon energy storage facility in the world, capable of storing both natural gas and hydrogen.
It does seem that Centrica have handled the Rough facility well.
But I do feel that Centrica are playing a bigger game.
- In Lhyfe And Centrica To Develop Offshore Renewable Green Hydrogen In The UK, I talk about how Centrica will produce hydrogen offshore.
- Would this hydrogen be conveniently produced near to Rough?
- Rough allow Centrica to buy gas at a low price and sell high. Rough could be a neat little profit centre?
- I suspect lessons learned at Rough, could be applied to other gas storage facilities?
- Centrica have taken a substantial stke in HiiROC, who are developing a new way of producing green hydrogen.
- In Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant, I talk about how Centrica are helping HiiROC with full scale trials.
I certainly like what they’re doing.
Centrica Signs UK Biomethane Agreement With Yorkshire Water And SGN Commercial Services
The title of this post, is the same as that of this news item from Centrica.
These three paragraphs outline the story.
Yorkshire Water, an essential water and wastewater services provider for the Yorkshire Region, and Centrica Energy Trading, have today announced signing a 15-year agreement to offtake biomethane production and manage shipping, trading, and balancing of production from two plants developed by SGN Commercial Services.
SGN, a leading manager of natural gas and green gas distribution networks in Scotland and the south of England will design, develop and operate the biomethane gas-to-grid sites, which once operational, will produce approximately 125GWh of biomethane annually — enough to heat more than 10,000 UK households.
Biogas will be produced as a by-product of Yorkshire Water’s sewage wastewater treatment processes, where Centrica will offtake production from the site and subsequently manage shipping, trading, and balancing of the green gas. Biomethane will be injected into the UK grid to displace natural gas, providing cleaner and more resilient gas supplies that reduces dependency on outside energy imports.
SGN Commercial Services are a wholly-owned subsidiary of SGN.
This mission statement is on the home page of their web site.
Our safety-first culture provides bespoke commercial solutions and green gas services to our clients, allowing them to better meet their business needs today and in the future.
In an energy market which is prioritising de-carbonisation and net-zero solutions, we can help navigate a clear pathway for your business to achieve its goals both responsibly and cost-effectively.
It looks to me, that SGN Commercial Services will design, develop and operate the biomethane gas-to-grid sites, so that the biomethane from the sewage works can be fed into Centrica’s main UK gas grid.
You could argue, that every sewage works and landfill producing large amounts of methane, should have one of these connections.
What would be the repercussions if SGN Commercial Services were asked to connect all these sites to the gas grid?
- How much gas would be collected?
- How many houses could be heated?
- How much of the greenhouse gas; methane would not be released into the atmosphere?
This is a cunning plan, that is worthy of Baldrick at his best.
Over a period of time, domestic gas consumption will fall as houses are fitted with heat pumps and other green methods for heating.
Could this mean, that as time goes on, more and more of our domestic consumption of gas is satisfied by net-zero gas from waste sources?
Does HiiROC Fit In Anywhere?
This article on UKTN is entitled Meet HiiROC, The Startup Making Low-Cost Hydrogen Free From Emissions.
There is a section, which is called How Does HiiROC Work?, where this is said.
The company’s hydrogen generation units use feedstock gases such as methane, flare gas or biomethane at high pressure and with a very high electrical field between an anode and cathode.
This dissembles the tightly bound molecules into hydrogen and carbon atoms, with both coming out as a plasma (like a gas). The carbon is instantly cooled and solidified as pure carbon, which means no carbon dioxide is formed, in a quenching process to stop it from reforming back into the input gas.
The end product is hydrogen and carbon black, a material used in rubber tires, inks and paint.
It’s a material that has wide industrial use, but current production methods create large amounts of CO2 and other environmentally harmful biproducts.
“Our process is emission-free,” says HiiROC co-founder and CEO Tim Davies. “Because all you’ve got is hydrogen and solid carbon – they are the two products.”
For every kilogram of hydrogen produced using HiiROC units, you’re left with three kilograms of carbon black. This, however, is a potentially valuable, clean solid by-product and does not contribute to global warming unlike processes that create carbon dioxide gas.
Read the full article on UKTN, as it is full of very interesting information.
It says this about distributing hydrogen to a number of industries.
Lots of industries need hydrogen, which means HiiROC has a broad range of potential customers.
Their smallest machine can produce up to 100 kilograms of hydrogen per day. But due to their modular design and small size, they can easily be stacked up to increase output, making them scalable for businesses requiring large-scale industrial hydrogen production.
So at one end of the scale, it could support a hydrogen filling station, or a farmer wanting to use hydrogen to go carbon-free and at the other, it could support an energy intensive process like hydrogen steelmaking. All that is needed is a suitable hydrocarbon gas feed.
Last night on the BBC, a program called What They Really Mean For You, was about electric cars.
The program flagged up a shortage of graphite for making the batteries for electric cars.
So seeing that HiiROC hydrogen systems, could be producing tonnes of carbon black could this be converted into battery-grade graphite?
Google says yes!
This article on Sciencing is entitled How To Turn Carbon Into Graphite.
Conclusion
As Centrica own a substantial portion of HiiROC and are lending the company a gas-fired power station for full scale trials, I believe that Centrica is up to something, that will have three strong benefits for the British public.
- They will be able to keep their gas boilers for longer.
- Hydrogen supplied by HiiROC’s devices will provide hydrogen in the required quantities to where it is needed.
- The carbon black produced by HiiROC’s devices, when turned into graphite will be a valuable feedstock for giga-factories making batteries.
Engineering is the science of the possible, whereas politics is dreams of the impossible.
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?
Plans Submitted For Hydrogen Pilot Plant At Humber Power Station
The title of this post, is the same as that of this article on Business Live.
This is the sub-heading.
HiiRoc and Centrica partnership at Brigg moves forward as consent sought.
These two paragraphs complete the original article.
Plans for a hydrogen pilot plant to sit alongside Centrica’s Brigg Power Station have been submitted to North Lincolnshire Council.
The low carbon fuel is set to be blended with gas at the peaking plant, in a tie-up between the energy giant and green-tech start up HiiRoc, in which it has invested. The well-backed Hull-based firm is pioneering a new production method, and was named as KPMG’s Global Tech Innovator for 2022.
I have very high hopes for HiiROC, who in addition to Centrica, have Hyundai and Kia as investors.
Endorsement from KPMG is surely positive.
Meet HiiROC, The Startup Making Low-Cost Hydrogen Free From Emissions
The title of this post, is the same as that of this article on UKTN.
This article explains the technology behind, what I feel is one of the most promising start-ups, I’ve seen.
It is certainly a must read.
This paragraph explains how they plan to lease the machines.
It plans to bring in revenue by leasing its machines to companies charging on the output of hydrogen and carbon.
That is almost how we sold the Artemis project management software, I wrote over forty years ago.
- Our bank manager liked it, as we were leasing to companies like BP, Chevron and Shell.
- His bosses liked it, as leasing companies don’t normally have that dodgy word; innovation.
- Our in-house accountant liked it, as we had an easy to predict cash flow.
- Our customers liked it, as all they had to provide was a 13-amp socket and paper for the printer.
It was a model that served us well.
Conclusion
The more I learn of HiiROC, the more I like the company.
