Molten Salt And Human Sweat: The Weird Batteries That Could Store Renewable Energy

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

This is the sub-heading.

From Nevada to Manchester, developers are trialling innovative solutions to clean energy’s biggest challenge

These first three paragraphs give a taste of what is to come.

In the deserts of the United Arab Emirates a sprawling clean energy project, stretching across an area roughly the size of 12,600 football fields, will play host to a breakthrough allowing solar energy to power the equivalent of half a million homes through the night.

The Gulf state has been steadily combining 5.2GW of solar power capacity with 19GWh of battery storage to create the largest battery scheme in the world.

Meanwhile, about 7,500 miles away, at the US’s National Renewable Energy Laboratory facility in Colorado, researchers and engineers are making some of the smallest batteries the world has ever seen. A fraction of the size of the grid-scale lithium-ion batteries used to store renewable energy, they have been designed to power electronic tags that will track the 3in-long (about 7.5cm) young from salmon and eel species.

And seeing, that they used to be the Manchester Guardian and that Andy Burnham is surely the man-of-the-day for other reasons, Highview Power’s 50 MW/300 MWh at Carrington in Manchester gets a big mention under a section heading of Liquid Air, with Burnham in hi-vis jacket and hard hat.

The article is very much a must read, that features projects from the United Arab Emirates, Colorado, Finland, Manchester, Nevada and Japan.

India’s First Hydrogen-Powered Train Notified: Know Route, Launch Date & What Makes It Special

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

These two paragraphs add some detail.

India’s first hydrogen train has been notified by Indian Railways. The new hydrogen-powered train is expected to be flagged off by PM Narendra Modi on July 17. He will also unveil a series of other infrastructure projectsacross Haryana, state minister Krishan Kumar Bedi said on Thursday.

The government says that project underscores Indian Railways’ wider focus on technological innovation, improved energy efficiency, and environmentally sustainable transportation, while supporting India’s national objectives on clean energy and achieving net-zero carbon emissions.

The route will be between Jind and Sonipat, which are both shown on this OpenRailwayMap.

Note.

  1. Jind, which has two stations Jind City and Jind Junction is in the North-West corner of the map.
  2. The blue arrow indicates Jind City station.
  3. Jind Junction station has a Wikipedia entry, which indicates that Jind Junction station has a hydrogen refilling station.
  4. Sonipat Junction station is in the South-East corner of the map.
  5. Jind and Sonipat are about fifty miles apart by train.
  6. OpenRailwayMap shows that most, if not all of the rail lines shown in this map are electrified using 25 KVAC overhead.

It looks to me, that Indian Railways are following similar rules to Network Rail, when they tested the battery-electric Class 379 train on the Mayflower Line.

  • Test new technology on a line with spare capacity.
  • Test new technology with a train, that can still run using current electrification.
  • Test new technology on an electrified line.

From talking to some of those, who used the Harwich train every day, there were no problems during the test.

Visiting The Hydrogen Train

I feel that if you were passing through New Delhi, it would be feasible, if you had time to spare to visit the hydrogen train.

Google AI says this about the New Delhi and Sonipat service.

Trains to Sonipat Station run directly from New Delhi Railway Station (NDLS). Several long-distance, express, and local EMU/MEMU trains connect the two stations daily, making the journey in approximately 30 to 50 minutes.

The Ghostly Drone That Spins Almost Too Fast To See

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

This is the sub-heading.

The ‘Phantom Twist’ prototype rotates about 25 times a second while its body moves in the opposite direction — appearing as a faint haze

These two initial paragraphs add some more details.

Engineers have created a drone that almost vanishes in flight by spinning so quickly the human eye sees only a faint, translucent haze.

The body of the drone, called the Phantom Twist, rotates about 25 times a second, while its propeller spins in the opposite direction. Its inventors describe it as “morphing into a ghostly smudge that seamlessly blends into the background”.

This technology obviously works and was developed at North Western University in the United States.

This paragraph speculates on a few civilian uses.

It is, they say, intended for civilian uses. The researchers believe less conspicuous aircraft could be useful for monitoring nesting birds, surveying wilderness areas or inspecting bridges and other infrastructure without causing wildlife to scatter or prompting people to alter their behaviour.

The article then details how drones have transformed the war in Ukraine.

TerraLithium, BHE Renewables Announce Key Milestones For Geothermal Lithium Project In California

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

This is the sub-heading.

TerraLithium and BHE Renewables have announced key milestones towards advancing technology for lithium extraction from geothermal brines in Imperial Valley, California.

This is the important paragraph in the article.

The business model of coupling lithium and critical minerals extraction with geothermal energy production is gaining increasing attention, both in the United States and in countries like Germany, France, and the UK. As demonstrated in the United Downs geothermal power project in Cornwall, lithium extraction provides additional revenue generation that can significantly improve the economics of deep geothermal projects.

So here we have little Cornwall showing Big California how to get power and lithium out of hot rocks.

In Cornish Plant Produces Geothermal Power, I described the progress at the Cornish plant in March.

Has Andy Burnham Ever Said Anything On Geothermal Energy?

Given that there is an election or coronation under way, I just had to ask Google AI, the question in the title of this section.

This is the answer I received.

Yes, Andy Burnham has occasionally engaged with topics involving geothermal energy, particularly in the context of tapping natural underground heat and mine water for green energy

His notable references to the technology include:

Supporting Manchester’s Geothermal Potential: He has voiced support for localized renewable heat projects, such as exploratory borehole plans in Manchester city centre intended to tap into thermal springs for community heating.

I think we can put that down as a favourable view.

This excellent article on the BBC is entitled Plan To Heat Manchester Homes With A Geothermal Spring, is worth a full read.

Is The UK Developing Sea-Drones To Protect Wind Farms?

I asked Google AI the question in the title of this post and received this answer.

Yes, the UK is actively developing and utilizing sea-drones (and autonomous boats) for its offshore wind farms. This technology is being used to protect the farms by patrolling subsea infrastructure, inspecting underwater turbine foundations, and delivering heavy equipment to mitigate human risk.

Here is a look at how sea drones and autonomous systems are being developed and used for the UK’s offshore energy sector:

Subsea Security and Patrolling: The UK and NATO are highly focused on protecting critical subsea cables and wind networks from adversarial interference. Firms like Aberdeen-based Honuworx have been contracted to develop autonomous underwater vehicles capable of prolonged remote operation for defense and infrastructure surveillance.

Underwater Structure Inspection: Projects like the UNITE program (led by Heriot-Watt University and supported by the National Robotarium) are testing AI-controlled underwater robots to operate in turbulent seas and maintain offshore wind infrastructure. Meanwhile, Beam (an offshore wind services company) successfully deployed the world’s first AI-driven autonomous underwater drone at Scotland’s Seagreen wind farm, cutting inspection times in half.

Sailing Drones & Remote Operations: Energy companies like Vattenfall are controlling uncrewed surface vessels (USVs) and sailing drones from remote operation centers in Aberdeen to patrol and keep North Sea wind farms safe and efficient.

Heavy-Lift Cargo Drones: Beyond sea drones, energy giant Ørsted has utilized giant autonomous drones to deliver heavy equipment—like 70kg boxes of safety gear—directly to the tops of offshore wind turbines in the UK, removing the need for ships and cranes in rough seas

We should fight fire with innovation.

Can A ‘Secret Sauce’ Help Store Renewable Energy?

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

This is the sub-heading.

The US-Israel war with Iran has led to higher electricity bills and put the issue of energy security back in the spotlight.

These two paragraphs add more detail to the story.

Now a pilot project inspired by a 100-year-old idea aims to store renewable energy.

Those behind the high density hydro demonstrator scheme near Plymouth say the technology can “turn small hills into giant batteries”, as part of the transition away from fossil fuels.

This is one of those stories, that could only emerge in the UK.

If you have the time, click on the link to the BBC article and read it in full.

I have a feeling, that the world will be hearing a lot about RheEnergise.

I asked Google AI, “How Much Energy Can A RheEnergise Battery Store”, and received this reply.

A RheEnergise system acts like pumped-storage hydro, using a dense fluid instead of water to store energy.

Planned commercial facilities are designed to store 2 to 16 hours of energy capacity, offering between 10 MW and 50 MW of power generation.

The exact energy storage figures for their deployments scale depending on the site requirements.

The breakdown of how these installations store and yield energy includes:

Commercial-Scale Capacity: A standard commercial site ranging from 10 MW to 50 MW will yield between 20 MWh and 800 MWh of total energy output (based on operating at full capacity for 2 to 16 hours).

The “Secret Sauce”: The system uses a proprietary fluid called R-19, which is 2.5 times denser than water.

This density allows the system to generate 2.5× more power and energy from the same physical footprint and vertical drop compared to traditional water-based facilities.

Real-World Pilot: The company operates a 500 kW demonstrator project at Cornwood near Plymouth, UK. This smaller test-bed, if run continually, generates energy equivalent to powering about 400 homes for an entire year.

Zero Seasonal Losses: Unlike chemical batteries (like lithium-ion) that degrade and lose charge over time, pumped hydro setups suffer virtually zero energy loss while the fluid sits idle.

National Grid Rollout New Technology To Expand The Capacity Of Existing Power Lines

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

These four bullet points act as sub-headings.

  • Latest rollout of Dynamic Line Rating (DLR) technology highlights spare capacity on existing power lines allowing greater power flows

  • New instalments on 585km of key north to south transmission network routes has the potential to save consumers up to £50 million in constraint costs

  • Over the last five years DLR has saved £21million in constraint costs and complemented upgrades to the existing transmission network (such as reconductoring and the use of power flow controllers) which have added over 16GW of new capacity to the existing network.

  • National Grid is unlocking more power from the existing grid faster and more cheaply, using innovative technology to meet increased demand, alongside constructing new infrastructure.

These first three paragraphs of the press release describe National Grid’s use of Dynamic Line Rating.

National Grid has announced a significant expansion of Dynamic Line Rating (DLR) technology across its electricity transmission network in England and Wales. Under a new five-year contract, Dynamic Line Ratings will be deployed across an additional 585km of key north-to-south transmission routes, potentially saving consumers up to £50 million over the next five years.

Meeting the growing demand for electricity requires both new infrastructure and smarter use of what already exists. DLR is an innovative yet proven technology that continuously monitors overhead line conditions to calculate a real-time capacity rating based on actual conductor behaviour and local weather, rather than the fixed conservative assumptions that have historically governed line ratings.

The result is a safe, reliable optimisation of available capacity on existing infrastructure, with the sensors and data analytics platforms allowing for a safe increase of the power carrying capacity of a circuit by an average of 8%. This reduces the need for constraint payments, where a generator is paid to stop generating to avoid overloading the electricity network.

This is an brilliant application of instrumentation, automation and very smart computing, that creates an average of eight per cent more capacity in the National Grid.

It’s like smart motorways for electrons, that from the press release appears to work.

I have some thoughts.

Reconductoring Is Mentioned

I suspect that the grid is highly instrumented and the grid can pick up areas that need to be replaced, but the masses of data a system like this will collect, will only improve their knowledge of the grid and give better predictions of where and how cables need to be replaced. Sophisticated modelling will also indicate, things like whether fatter cables here and there could squeeze more capacity into the network.

In the 1970s, I provided the software for the Water Resources Board to analyse and plan the pipelines and reservoirs for water supply in large parts of England.

Given that over the years, most of the problems over the years with the water industry, seem to apply to sewage, ownership, politics, equipment failure, rather than taps actually running dry, I suspect that Dr. Dimeloe and his team did a magnificent job. I would love to know the truth from one of the team.

As fifty years later, modelling software must be more sophisticated, I suspect a continuous analysis of the grid could give substantial benefits.

More And Better Sensors Will Be Developed

As needs arise, the systems will get more and more sophisticated and I wouldn’t be surprised to see the capacity of the grid increase by more than expected.

There Are 4,000 Miles Of High Voltage Overhead Lines In The UK

So if, National Grid can get an eight percent increase as the press release indicates, they might be able to add the equivalent of 320 miles to the electricity transmission network, without the hassle of applying for planning permission or dealing with Nimbies.

There might also be a cost saving as Google AI indicated that high voltage transmission lines cost around two million pounds per mile.

I Can Envisage Sophisticated Connection Networks For Offshore Wind Farms Using Coastal Or Even Offshore Batteries To Maximise The Energy Generated

Consider.

  • The output of a wind farm varies throughout the day and night.
  • Some of the variation in a wind farm’s output may be predictable.
  • Batteries and/or capacitors are good at smoothing variation in electrical power output and demand.
  • Capacitors are useful for smoothing out high-frequencies.
  • Highview Power are now building a 50 MW/300 MWh and a 500 MW/3.2 GWh battery, that both come with a sophisticated control system, they call a stability island providing inertia (frequency stability), short-circuit strength, and voltage control.
  • Dynamic Line Rating can be applied to the transmission line, that connects the wind farm and the battery to the grid.

Getting all these assets to work as a team, is a challenge some of the world’s best engineer/programmers would relish.

I could envisage, that systems like this could deliver hundreds of mill-pond smooth megawatts, that would be just what data centre owners wanted and needed.

Conclusion

The application of Dynamic Line Rating is going to revolutionise the electricity grid all over the world.

Record Public Transport Growth To The Lake District As Keswick Added To National Rail Network

The title of this post is the same as that of this article on Rail Technology Magazine.

This is the sub-heading.

Record numbers of visitors are travelling to the Lake District by public transport after Avanti West Coast introduced a “virtual railway station” at Keswick, according to newly released figures.

These two paragraphs add more detail.

By adding Keswick to national rail journey planners, passengers can now purchase a single, fully integrated ticket covering both train and bus travel. From today (27 April), the ticket will be available year‑round following a successful two‑summer trial.

The initiative allows passengers to travel on Avanti West Coast or TransPennine Express services to Penrith – the gateway to the North Lakes – before continuing to Keswick on Stagecoach’s X4 and X5 bus services, all using one ticket.

This paragraph describes the impact of the initiative.

The impact has been significant. Over the past year, Avanti West Coast, TransPennine Express and Stagecoach have all reported record-breaking passenger growth, underlining growing demand for seamless, car‑free travel to one of the UK’s most popular visitor destinations.

That looks like a good result all round.

I have some thoughts.

Buying A Ticket

I have just tried to book a ticket between Euston and Keswick for tomorrow, using my normal ticket retailer.

  • The destination was Keswick Bus.
  • It was just like buying a ticket between Euston and Liverpool Lime Street.
  • I could have entered my Senior Railcard.
  • The only thing that is needed would be to ask if you have a bus pass and adjust the ticket price accordingly.

I think one day in the summer, if I’m at a loss for something to do, I might visit Keswick.

I also found Keswick Bus on this ticket machine at Kings Cross.

Someone is getting the Ticketing Act together.

Getting To Events

In 2011 I visited all 92 English League Clubs in alphabetical order and some were difficult to get to from the nearest station.

Perhaps if a club has a bus between the local station and the ground, a virtual station could be added, which might be called say York Football.

There would be details instructions at the exit to the station about where to catch the bus or how to walk there if it were close.

It would obviously work for other sports and what about events like Glastonbury, Glyndebourne, The Suffolk Show and racing of both horses and horsepower.

Testing The Viability Of Possible Stations

It is very difficult to test the viability of a new station before a large sum of money can be allocated to build the station.

But supposing Merseyrail wanted to test the viability of a new station at Skelmersdale.

  • Skelmersdale Bus would be added to the Rail Ticketing System.
  • A bus route would be created probably between the new station at Headbolt Lane and Skelmersdale.

Done properly, it could give a reasonable estimate of the viability of the new route.

Conclusion

I can see this being a very popular and successful development.

Centrica Energy Signs Biomethane Agreement With Stream BioEnergy

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

This is the sub-heading.

Centrica Energy, in collaboration with Bord Gáis Energy, has signed an agreement with Stream BioEnergy to provide long term offtake and route-to-market services for Ireland’s largest biomethane facility processing municipal food and garden waste under development near Cork, Ireland. The plant will convert food and green waste into renewable biomethane for injection into the Irish gas grid, supporting the country’s decarbonisation goals and circular economy ambitions.

These two paragraphs add more details.

Stream BioEnergy is a leading developer of biogas plants in Ireland, and this new project represents a significant step forward in scaling sustainable gas production from organic waste. When operational in 2027, the new plant will process 90,000 tonnes per year of domestic and commercial food and garden waste to generate 80GWh annually of unsubsidised biomethane.

Under the agreement, Centrica Energy will offtake 100% of the biomethane produced at the facility and manage the associated green certificates, ensuring the renewable gas reaches end users efficiently and sustainably. The deal is supported by Bord Gáis Energy, Centrica’s Irish energy supply business, which will play a key role in enabling the delivery of biomethane to the Irish market.

It looks like Centrica are using their expertise to distribute the gas and do all the required green paperwork.

 

What Is The Major Use In Ireland Of Biomethane?

This was the obvious question to ask Google AI.

I received this answer.

The major use of biomethane in Ireland is as a renewable substitute for natural gas, primarily injected directly into the national gas grid to decarbonise the heating, industrial, and transport sectors.

While currently a developing industry (with around 75 GWh per annum produced in 2024), Ireland’s National Biomethane Strategy aims for a rapid scale-up, targeting 5.7 TWh by 2030 to meet 10% of national gas demand.

Key areas of focus include:

Grid Injection & Heating: Biomethane is injected into the gas network to decarbonise residential, commercial, and industrial heating.

Transport Fuel (Bio-CNG): It is used as a sustainable alternative to diesel for heavy-duty vehicles (HGVs) and buses, often under the Renewable Transport Fuel Obligation (RTFO).

Industrial Use: It is employed in sectors that are difficult to electrify, helping companies meet sustainability and carbon reduction goals.

Circular Economy/Agricultural Support: The production process creates a byproduct called digestate, which is used as a sustainable bio-fertiliser, helping farmers reduce reliance on chemical fertilisers.

The sector is currently shifting from relying solely on food waste to incorporating agricultural residues like slurry and grass silage.

Are Centrica Involved In Biomethane In The UK?

Out of curiosity, I had to ask Google AI this question.

I received this answer.

Yes, Centrica is actively involved in the biomethane sector in the UK, focusing on offtaking, trading, and transporting green gas, as well as investing in infrastructure.

Key aspects of their involvement include:

Partnerships and Offtake Agreements: Centrica Energy Trading has signed a 15-year agreement with Yorkshire Water and SGN Commercial Services to offtake biomethane from two new gas-to-grid plants in Yorkshire.

Production Capacity: The aforementioned plants, located at Blackburn Meadows and Knostrop, are designed to produce approximately 125GWh of biomethane annually, sufficient to heat over 10,000 homes.

Investment in Bio-LNG/CNG: Centrica acquired a 16% stake in Gasrec, the UK’s largest provider of bio-LNG (liquefied natural gas) and bio-CNG (compressed natural gas) for heavy goods vehicles, supporting the decarbonization of road transport.

Green Gas Trading: Through partnerships like the investment in Barrow Green Gas (BGG), a leading UK green gas supplier, Centrica has established itself as a major player in shipping green gas in the GB network.

Industrial Solutions: Centrica Business Solutions offers “Biomethane CHP” (Combined Heat and Power) to large organizations, enabling them to use green gas certificates to reduce their carbon footprint.

Centrica is aiming to expand its biomethane activities to support its net-zero goals, with a particular focus on using sewage treatment and other waste products for energy.

This seems to fit the pattern of the Irish deal.

Could Centrica be looking for lessons in Ireland, that can be applied to the UK market?

Do British Gas Research Have A Reputation For Innovation?

As British Gas Research developed the heata, which is an idea I like, I felt that it could be enlightening to ask this question of Google AI.

I received this answer.

Yes, British Gas (and its parent company Centrica) has a strong, long-standing reputation for innovation, particularly in the areas of home energy technology, customer services, and net-zero solutions. Their research and development (R&D) efforts are focused on energy efficiency, smart technology, and decarbonization.

Key areas where British Gas demonstrates a reputation for innovation include:

Smart Home Tech (Hive): British Gas pioneered the mass adoption of smart thermostats in the UK with the launch and development of Hive, a key part of their digital strategy for home energy management.

Low Carbon & Renewables: The company is a leading installer of heat pumps and is actively involved in hydrogen innovation for heating solutions.

Digital Customer Experience: They have utilized AI for, among other things, automating complaints root cause analysis and have developed advanced digital tools to allow customers to manage energy usage via apps.

Energy Transition Research: Through Centrica, they invest significant amounts annually in renewable generation and flexible energy solutions to meet net-zero targets.

Data Analytics: British Gas has partnered with research firms to use technologies like eye-tracking to improve the effectiveness of their digital ads and customer engagement.

Strategic Partnerships: They collaborate with industry leaders like Samsung and Barclays to provide energy efficiency incentives and optimize home appliance use.

While they are a major player in new technologies, it is important to note that the broader gas industry is currently focusing on “digital by default” and “flexible and seamless connections” for green gases, as part of their 2026-2028 strategy.

British Gas Research could give the sort of support, that those in the front line need.

Lumo Targets Drivers With ‘Pump-Primed’ Campaign Showing How To Travel To London For Less

The title of this post, is the same as that of this article on Rail Business Daily.

These three paragraphs outline the story.

Motorists driving to London are being shown how taking the train could save up to half the cost of their journey – as they fill-up at the fuel pumps.

Lumo has launched digital screens at a filling station to display real-time travel information and ticket prices.

Lumo believes the bold new trial, a first-of-its-kind partnership with the Smart Outdoor digital advertising firm, will give motorists a timely reminder of a greener and often more affordable alternative to driving between Scotland and England.

Note.

  1. Displaying real-time travel information is done regularly all over the transport network, for buses and trains.
  2. Adding ticket prices would not be difficult.
  3. All filling stations must have good enough broadband.
  4. I suspect, it could work best, where the train operator sells good value walk-up tickets. This is done at LNER stations on the East Coast Main Line and in An Affordable Trip To Doncaster, I told how I went to Doncaster for the day for £46.45 with a Senior Railcard, buying the tickets on a walk-up basis.

But who knows, where this technology will lead?

As a non-driver, if anybody sees the system in action, I’d love a comment and a photo.

A Ticket Buying App

I also think, I could specify a ticket buying app for trips someone needs to make.

The app would keep a list of train journeys you want to make.

Every day, it would look up the best prices available and if you wanted to go somewhere, you could buy a ticket.
