Cold Snap Leaves Britain With Less Than A Week’s Worth Of Gas

The title of this post, are the same as that of this article on The Times.

This is the sub-heading.

The closure of Russian pipelines through Ukraine and recent weather conditions have left gas stores ‘concerningly low’

These are the first two paragraphs.

Britain has less than a week of gas supplies in storage, the country’s largest supplier has warned after plunging temperatures and high demand.

Centrica, the owner of British Gas, said the UK’s gas storage was “concerningly low” after coming under pressure this winter.

The two largest gas storage facilities in this country are both in the Humberside area.

  • Aldbrough is in salt caverns North of Hull and is owned by SSE.
  • Rough is under the North Sea and is owned by Centrica

Both are being converted to store hydrogen.

Some might thing that is a bit stupid if we’re short of storage, but we need the hydrogen storage for four reasons.

  1. To store hydrogen created by electrolysers on Humberside, which will enable heavy gas users in the area to decarbonise.
  2. The hydrogen will also be burnt in a 1 GW hydrogen-fired power station at Keadby to back up the wind turbines, with zero-carbon electricity.
  3. The hydrogen will also be sold to the Germans to replace Putin’s blood-stained gas. It will be sent to Germany in a pipeline called AquaVentus, which will also deliver Scottish hydrogen across the North Sea. Hopefully, the Germans will pay a good price for the hydrogen.
  4. The hydrogen will be used for transport.

The mistake the Government is making is not to develop smaller gas fields, so that domestic gas users can continue to use natural gas, until the technology to replace it with zero-carbon sources is fully developed.

Start-Up’s Plan To Convert Food Waste Into Green Fuel

The title of this post, is the same as that, of this article in The Times.

This is the sub-heading.

Dark Green wants to build biogas production plants to supply local authorities and businesses

These three paragraphs give some detail to the plans.

A Nottingham-based start-up wants to become the first company to build a fleet of plants that would convert food waste into green energy in urban centres across Britain, producing an alternative fuel for businesses and local authorities attempting to shrink their carbon footprints.

Dark Green expects to submit planning applications for six biogas production plants, including one each in Birmingham and Huddersfield, with a further six in the pipeline.

The facilities, which are more usually sited on farms, will be capable of handling 60,000 tonnes of organic waste a year, saving the same amount of carbon dioxide as taking 65,000 cars off the road, the company estimates, and will produce seven megawatts of energy, capable of powering around 6,000 homes.

I have a feeling that Dark Green fit a theme, that this blog has been following for a couple of years now.

I have been  commenting on a company called HiiROC.

  • I first became aware of HiiROC and their new method of generating hydrogen in this news item from Centrica, which is entitled Centrica And HiiROC To Inject Hydrogen At Brigg Gas-Fired Power Station In UK First Project.
  • HiiROC is a Hull-based startup-up, that is backed by Cemex, Centrica, Hyundai, Kia, Siemens and other big names.
  • HiiROC can take any hydrocarbon gas from something like chemical plant off-gas, through biomethane to natural gas and split it into hydrogen and carbon black.
  • HiiROC call their process thermal plasma electrolysis.
  • The carbon black has uses in the manufacture of tyres and rubber products, anodes for lithium-ion batteries and other materials and in agriculture, it can be used to improve soils.

HiiROC claim that their method uses a fifth of the energy to create hydrogen, than electrolysis.

It looks to me that if you pipe Dark Green’s methane-rich gas into one of HiiROC’s thermal plasma electrolysers, you’ll get two valuable products; hydrogen and carbon black.

Centrica have also been active with an energy storage company called Highview Power recently, in the company of Goldman Sachs and Rio Tinto.

Centrica seem to have a cunning plan!

Is Dark Green going to be part of it?

British Gas Partners With Strata And Daikin To Launch Eco-Tech Low Bill Homes

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

This is the sub-heading.

British Gas is set to supercharge sustainable living across the UK with the launch of Low Carbon Homes – a ground-breaking pilot in partnership with Strata and heat pump manufacturer, Daikin.

These are the first four paragraphs, which fill out a bit of detail.

In anticipation of The Future Homes Standard, customers will move into new build homes which have been fitted with a full range of the latest low-carbon technology at no extra cost to the housebuilder or owner. The homes will be equipped with a 6-8 kWh Daikin air source heat pump, 4 kWh solar panels, 5 kWh battery storage, Hive electric vehicle charger and thermostat. These items will be integrated into Hive’s award-winning app, providing customers with one-stop visibility and control of their energy usage.

The first trial phase will launch at a Strata’s “Breathe” development site in Kiveton, Rotherham. As a thank you for participating in the pilot, British Gas is giving homeowners access to a fixed rate tailored British Gas tariff. Participants in the trial will also have access to a dedicated British Gas energy manager to help them optimise the technology and keep bills as low as possible, while still meeting their desired comfort levels.

Each home will be fitted with a Hive hub, which connects to the WIFI network and acts as the home’s operating system, integrating all the sustainable technology. The customers energy and heat schedules and budget will be optimised by the Hive Hub for further savings.

When the customer connects to Hive’s app they will be able to control and maximise efficiency by setting schedules and spending budgets and allowing the Hub to help them reduce their bills.

Note.

  1. As a Control Engineer, this to me is a good start.
  2. I suspect that a 6-8 kWh Daikin air source heat pump, 4 kWh solar panels and  5 kWh battery storage will keep the average house warm.
  3. I would expect that the three companies have optimised the ratios between the sizes of the components to give the best performance.

It is amazing to think that it was in the early seventies, that in the two sections, where I worked at ICI, engineers had just started controlling  and optimising flows, pressures and temperatures in complex chemical plants.

If you’d asked any of us, when our houses heating systems would be as fully controlled, we’d have given twenty years at most.

What kept the world so long?

I have a few thoughts.

Could The Housing Have Gas For Cooking??

Yes! Centrica owns a big share with Hyundai, Kia and others of a start-up company called HiiROC.

  • This is the HiiROC web site.
  • HiiROC can take any hydocarbon gas and split it into green hydrogen and carbon black.
  • Green hydrogen is obviously useful and the carbon black can be used for making tyres for vehicles, anodes for lithium-ion batteries and in agriculture for soil improvement.
  • Waste off-gas from a chemical plant can be split into green hydrogen and carbon black.
  • Biomethane from a sewage plant can be split into hydrogen and carbon black. Could a sewage plant on an estate be used to create biomethane for cooking and feeding to the HiiROC plant? Yes!
  • Could green hydrogen produced on the estate be used to drive vehicles like cars, vans and ride-on-mowers. Yes! If the manufacturer of the vehicle allows it!
  • How convenient would it be to have Hydrogen-at-Home?

How Much Does A British Gas Hive Save On My Energy Bill?

I asked Google and I got this answer from Home Hive.

£119. A smaller carbon footprint and a smaller bill – our award-winning smart thermostat could cut your energy bills by up to £170 a year. Join Hive Plus to boost your thermostat’s savings – and get exclusive access to £60 bill credit with any fixed British Gas dual fuel tariff.

At present, I have no intention of changing my energy supplier, but come the summer or if my health or energy circumstances change, I might see what is available.

Will British Gas Develop A Hive For a Smaller Dwelling?

I suspect in ten years, if I’m still of this world, I shall be living in the following circumstances.

  • Alone.
  • In a two bedroom house, cottage or flat.
  • Some form of probably electric central heating or perhaps even hydrogen.
  • No car.
  • A short walk to the bus stop and/or train station.
  • Communal gardens to sit in.
  • An Ocado style delivery for food, groceries and other essentials.
  • A local gluten-free cafe.
  • Full Wi-Fi

Perhaps, British Gas and others will develop a community for people like me?

Large Scale Hydrogen Storage Sites Could Reduce Customer Energy Costs By £1bn Per Year

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

These four paragraphs summarise the report.

Centrica and FTI report finds that hydrogen storage would help balance the UK’s energy system and reduce bills.

A net zero scenario including large scale hydrogen storage – specifically, a redeveloped Rough gas storage facility – would reduce energy costs by an additional £1bn per year by 2050.

Report also finds that a UK energy system focused on renewable generation risks high levels of intermittency without an established hydrogen market. By 2050, electricity generation from renewables could exceed total demand around 15% of the time.

Electricity generation from renewables could also rise or fall by as much as 100GW over the course of a single day. More than twice current levels of peak demand on winter evenings and the equivalent energy output from over 30 Hinkley Point C nuclear power stations.

Note.

  1. Hydrogen Central entitles their article about the Centrica press release Centrica Says Hydrogen Can Reduce Household Bills by £35 a Year. That’s almost a bottle of my favourite Adnams beer a week!
  2. I talked about the redevelopment of the Rough facility into hydrogen storage in Aberdeen’s Exceed Secures Centrica Rough Contract.
  3. Generating hydrogen from excess electricity and storing it until it is needed, must be an efficient way of storing electricity or powering industrial processes that need a lot of energy, if storing hydrogen makes £1bn per year!
  4. It should be noted that Centrica have a large interest in HiiROC, who are developing an efficient way to generate hydrogen from any hydrocarbon gas from chemical plant off-gas through biomethane to natural gas. In a perfect world a HiiROC system in a sewage works could capture the biomethane and split it into hydrogen and carbon black. The hydrogen could be used to refuel vehicles and the carbon black would be taken away to someone, who has need of it.

In some ways, it is surely sensible to have enough energy in a store, if the renewables fail. As Rough is already there and functioning, it is surely one of the easiest routes to redevelop Rough, so that it is in top-quality condition.

It should also be noted, that Rough is not far from the Aldbrough Gas Storage, which SSE are converting to a second massive hydrogen store.

So Humberside will have two of the largest hydrogen stores in the world, which Centrica and SSE will use to maxise energy security in the wider Humberside and East Yorkshire area, and I suspect to maximise their profits as well.

This video shows the structure of AquaVentus, which is a pipeline system, that the Germans are building to bring much-needed hydrogen to German industry from electrolysers in the North Sea and other countries like Denmark, Norway, the Netherlands and the UK.

I clipped this map from the video.

Note how a branch of AquaVentus makes landfall around the Humber estuary at a UK label.

Will Centrica and SSE be trading hydrogen from Rough and Aldbrough with the Germans through AquaVentus? You bet they will, as the Germans are short of both hydrogen and hydrogen storage.

Bord Gáis Energy Acquires Leading Irish Solar PV Installer Swyft Energy

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

This is the sub-heading.

Bord Gáis Energy today announced the acquisition of Swyft Energy, a leading solar PV provider in Ireland for an undisclosed sum.

Note.

  1. Bord Gáis Energy is a subsidiary of Centrica.
  2. Swyft Energy has this web site.

These three paragraphs give more details of the acquisition.

Bord Gáis Energy already operates in the solar PV market: directly to residential customers, and through its partnership with Irish Farmer’s Association delivering solar PV to farms across Ireland, helping farmers transition to green energy. The acquisition of Swyft Energy now brings deeper solar PV capability to residential as well as business and farming customers of Bord Gáis Energy, as the company transitions to a green energy business.

Swyft Energy, a technology-led solar PV and boiler installation company, brings over six years of experience in delivering customer-focused solutions using a digital-first platform. This acquisition enhances Bord Gáis Energy’s highly skilled workforce and strengthens its customer proposition.

With a target of 10,000 installations over the next 5 years, this will allow Bord Gáis Energy to compete better for the growing demand for solar energy in residential, commercial and agricultural sectors. Customers can save an average of 50-70% on their electricity bills with the installation of rooftop solar panels.

The deal certainly looks a good fit between two ambitious companies, who are operating in similar areas of the Irish market.

I have my thoughts and observations.

Are Bord Gáis Energy And Swyft Energy Stronger Together?

Do both companies feel, that by working together, they will be stronger from a financial point of view?

It wouldn’t be unusual for this to be a reason behind a deal like this.

Centrica Are Making Lots Of Deals At The Present Time

Centrica are also continuing, the tendency to expand, that they’ve shown in recent weeks.

These are some of the deals I have noted.

Centrica certainly have been busy expanding.

Energy Storage In The Island Of Ireland

It is generally accepted, that if you have a lot of renewable energy, then you need a lot of energy storage, to bridge the gaps in wind and solar.

In the Wikipedia entry for Energy In Ireland, there is a section called Energy Storage.

It seems to me, that Ireland could be short on energy storage, so is it likely that the enlarged Bord Gáis Energy will look for possibilities for energy storage.

Recently, Centrica formed a business relationship with Highview Power, who are developing environmentally-friendly liquid-air batteries. These smaller and more affordable batteries might be suitable for the island of Ireland.

Conclusion

There’s more to this deal, than at first meets the eye.

HiiROC Partners With Siemens To Boost Clean Hydrogen Production

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

These two bullet points, act as sub-headings.

  • HiiROC and Siemens sign a Memorandum of Understanding to provide advanced control technology and ensure the safe automation of hydrogen production.

  • HiiROC’s Thermal Plasma Electrolysis (TPE) process produces clean hydrogen and solid carbon, using significantly less electricity than water electrolysis and without creating carbon dioxide.

These five paragraphs explain the deal.

Clean hydrogen producer HiiROC, has partnered with technology company Siemens on its hydrogen production technology, helping customers to decarbonise their operations and support their Net Zero ambitions.

Under the agreement, HiiROC will leverage Siemens’ control technology and factory and automation expertise to ensure the safe, efficient automation of hydrogen production and support in scaling.

HiiROC’s proprietary Thermal Plasma Electrolysis (TPE) technology is designed to meet rising demand for low-cost, scalable solutions for clean hydrogen production at the point of use, which helps to significantly reduce costs by removing the need for specialised storage and transportation.

The TPE process disassembles gaseous hydrocarbons into hydrogen and solid carbon without creating carbon dioxide. This highly efficient process, recognised under the UK’s Low Carbon Hydrogen Standard, requires only a fifth of the electricity of water electrolysis.

As a key technology partner, Siemens will collaborate with HiiROC to advance product development, while its global developer support community will help in achieving the hydrogen producer’s international expansion goals. Siemens, which has ambitious commitments to decrease carbon emissions and contribute to a more sustainable society, works with organisations across sectors to decarbonise using technology.

Many chemical processes are all about brute force and very large amounts of energy. This marriage made in chemical heaven, is all about elegance and finesse.

The investors in HiiROC are not without substance and include Melrose Industries, HydrogenOne, Centrica, Hyundai and Kia.

I wrote more about HiiROC and a similar process in Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant.

Aberdeen’s Exceed Secures Centrica Rough Contract

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

This is the sub-heading.

Well and reservoir management firm Exceed has secured a contract with Centrica Energy Storage for the redevelopment of the Rough gas storage field.

This is the introductory paragraph.

Exceed said its role in the initial stages of the project, which is exploring converting the Rough field into a hydrogen storage facility, could create more than 30 jobs.

In Wood To Optimise Hydrogen Storage For Centrica’s Rough Field, I talked about changing Rough from a gas to a hydrogen store, so it looks like Centrica are going to create a vast hydrogen storage facility.

This all fits with my belief, that Centrica’s Rough facility and SSE’s nearby Aldbrough storage facility, will at sometime in the future be connected to the Germany hydrogen pipeline; AquaVentus to perform backup to hydrogen produced in the North Sea.

I also feel that the hydrogen trading will be of benefit to Centrica and SSE.

The last section of the Energy Voice article is entitled Rough Hydrogen Storage Concerns.

The following facts are given.

There are currently eight geological gas storage sites across Great Britain, containing approximately 3.1bcm in capacity and maximum deliverability rates of 124mcm/day.

Five of these gas storage sites are in salt caverns while the remaining three are depleted oil and gas fields, with the Centrica’s Rough field in the North Sea the only site located offshore.

The British Geological Survey estimates the UK could store up to 3,000 TWh of hydrogen.

Currently, we use the following energy in a year.

  • 263 TWh of electricity
  • 705 TWh of natural gas

So we use a total of 968 TWh of energy.

3,000 TWh of hydrogen would keep the UK going for three years. So we should be fine!

Centrica And Coterra Energy Announce Natural Gas Sale And Purchase Agreements

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

These three bullet points, act as sub-headings.

  • Coterra will supply 100,000 MMbtu/d of natural gas for a period of 10 years, commencing in 2028.
  • Volume supplied sufficient to heat 400,000 homes per year.
  • Agreement expands Centrica’s growing LNG business.

These three paragraphs say more about the deal and add more on its context.

Centrica LNG and Coterra today announced the execution of two natural gas sale and purchase agreements. Under the contracts, Coterra will supply 100,000 MMbtu/d of natural gas linked to European gas prices such as TTF and NBP, for a period of 10 years, commencing in 2028.

This major gas deal will reduce the market risk in Centrica’s LNG portfolio by purchasing US gas on the same price indices under which the LNG is subsequently sold, and help underpin customer energy supplies for a decade. The volume supplied is sufficient to heat 400,000 homes per year, further cementing Centrica’s global role supporting energy security.

The deal follows similar agreements over recent years, demonstrating Centrica Energy’s innovative partnership approach, one of the key pillars of its successful and growing LNG business.

It certainly looks like Centrica are doing their best for UK energy security.

It also looks to me, that it is a low risk deal.

It should also help to keep us all warm in the UK, until renewable electricity and hydrogen come fully on stream.

Centrica And European Energy Sign Agreement On Måde Green Hydrogen Facility

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

This is the sub-heading.

Centrica Energy and European Energy have signed a balancing and optimisation agreement for the Måde green hydrogen facility located at Port Esbjerg. Under the agreement, Centrica Energy will manage power production from co-located wind turbines, designating excess power production to green hydrogen production.

These two  introductory paragraphs give more details.

Powering the 12MW green hydrogen facility are two wind turbines, part of the Måde Wind Turbine Test Center, developed by European Energy with a total installed capacity of 16MW. The turbines will provide renewable electricity, which is used to produce green hydrogen through electrolysis with demineralised water.

Expected to produce approximately 1,500 tonnes of green hydrogen every year, European Energy has secured an agreement with Port Esbjerg and a world-class industrial gases company for the offtake from the facility. As the production of hydrogen is a heat-intensive process, the excess heat from production will be fed into the local district heating network, demonstrating sector coupling across the electricity, fuel, and heating domains.

These are my thoughts,

Hydrogen Production

The hydrogen production uses a standard electrolysis method, but excess heat will be fed into the local district heating network.

AquaVentus And Denmark

I introduced AquaVentus in this post called AquaVentus.

This video shows the structure of AquaVentus.

I clipped this map from the video.

Note.

  1. The thick white line running North-West/South-East is the spine of AquaVentus, that delivers hydrogen to Germany.
  2. There is a link to Esbjerg in Denmark.
  3. There appears to be an undeveloped link to Norway.
  4. There appears to be an undeveloped  link to Peterhead in Scotland.
  5. There appears to be a link to just North of the Humber in England.
  6. Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
  7. There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?

In the last century, the oil industry, built a substantial oil and gas network in the North Sea.

It appears now the Germans are leading the building of a substantial hydrogen network in the North Sea, that will bring the hydrogen they need to their country.

I also suspect that any spare hydrogen produced in Esbjerg can be added to the AquaVentus network.

  • Hydrogen could be sent to Brough and Aldbrough in the UK for storage.
  • Hydrogen could be sent to any country in the network that needs it.

Countries will pay for the hydrogen they use.

Optimising AquaVentus

AquaVentus is a complex network.

  • Hydrogen could be produced offshore in British, Danish, Dutch, English, German, Norwegian, Orcadian, Scottish and Shetland waters.
  • Hydrogen could be sent to Brough and Aldbrough in the UK for storage.
  • Hydrogen can be sent to Belgium, Denmark, Germany, Norway, The Netherlands and the UK.

A company like Centrica has the expertise and the software to control the various hydrogen flows to the best advantage of hydrogen producers and users.

Hydrogen Energy Explained

The title of this post, is the same as this story on Centrica.

This is the sub-heading.

Hydrogen is a clean alternative to natural gas, when it’s burnt it doesn’t produce carbon dioxide, which is a harmful greenhouse gas. It has the potential to play a significant role in achieving net-zero and decarbonising various sectors.

The story is a good introduction to hydrogen.

In the 1960s, when I first worked in a hydrogen electrolyser at ICI in Runcorn, I would have found a document like this one from Centrica invaluable.
