Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?
From some work I did at ICI in the 1970s on a PACE231R analog computer, I believe that Highview Power may have an extremely promising way of storing energy.
The Highview Power web site talks of Sumitomo Heavy Industries, who are building one of Highview’s batteries at Hiroshima in Japan.
So I asked Google AI the question in the title of this post and received this comprehensive answer.
Yes, the Sumitomo Heavy Industries (SHI) Highview Power liquid air energy storage (LAES) commercial demonstration plant in Hatsukaichi, Hiroshima, is operational, having commenced operations on December 1, 2025.
Key details about the plant:Location: Within the Hiroshima Gas Hatsukaichi LNG Terminal.Capacity: 5 MW output with 4-hour storage (4 MW charging).Technology: Uses Highview Power’s CRYOBattery™ technology, specifically utilizing waste cold from the adjacent LNG terminal to improve efficiency.Role: The facility is designed to support grid stability and enhance renewable energy integration.A completion ceremony for the project was held on December 9, 2025. This news item from Sumitomo Heavy Industries gives more details.This paragraph describes Liquid Air Energy Storage or (LAES).
- It looks like the battery has a capacity of 5 MW/20 MWh.
- As it talks about using waste cold, this looks to be a very professionally-designed specialist application.
- But surely, that would be expected from a company like Sumitomo Heavy Industries.
There are hundreds of LNG terminals globally, with significant growth driven by over 300 projects (roughly 177 import/regasification and 124 export/liquefaction) expected between 2025 and 2030. In 2023, there were 22 countries with active liquefaction (export) capacity, while Europe alone operates roughly 28 large-scale terminals, supplemented by a rapidly expanding fleet of FSRUs.Export Capacity: In 2023, global liquefaction capacity was 472 million tonnes per annum (mtpa), with top exporters being Australia, the U.S., and Qatar.Expansion: By 2027, 52 new liquefaction terminals are expected to commence operations.Import Growth: European regasification capacity is expanding, with major terminals in Spain, France, Italy, and new additions in Germany and other nations.U.S. Infrastructure: The U.S. alone has more than 170 LNG facilities performing various services.
- They are listed in this Wikipedia entry.
- There are around thirty in Japan alone.
- Will Centrica add a 5 MW /20 MWh Highview Power battery to their Grain LNG Terminal?
- Each facility installed is claimed to be designed to support grid stability and enhance renewable energy integration, so the last part must cut carbon emissions.
Yes, several major chemical engineering and industrial processes generate significant amounts of “waste cold” (low-grade thermal energy or cryogenic energy) that is often discarded. While the chemical industry conventionally focuses on recovering waste heat, recovering waste cold is becoming increasingly popular for improving energy efficiency, particularly in cryogenic processes.

Japanese Company Takes Part In Spain’s Floating Wind Demonstration Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Japan’s Electric Power Development, also known as J-Power, has joined the WHEEL floating offshore wind demonstration project in Spain.
These three paragraphs add more details.
The WHEEL demonstration project is led by the Madrid-headquartered company Esteyco. WHEEL will feature one turbine installed three kilometres off the eastern coast of Gran Canaria, Spain.
Through this project, J-Power aims to acquire knowledge in the manufacturing, assembly, installation, and operation of floating offshore wind power, contributing to the development of floating offshore wind projects in Japan and abroad, the company said.
A floating offshore wind turbine, with a capacity of 6.17 MW, will be constructed and tested using WHEEL, which combines the advantages of barge-type foundations and spar-type foundations.
There is a visualisation of the WHEEL project in the linked article.
Conclusion
I like the concept of WHEEL.
In Norwegians Developing Monopile Foundation For 100-Metre Depths, I write about my involvement with a company called Balaena Structures in the 1970s, who were trying to develop a reusable oil and gas platform. I have a feeling, that WHEEL and the Balaena have dynamic and floating properties in common.
World’s First Public Demonstration Of Hydrogen Engine Motorcycle
This title of post, is the same as that of this news item from Kawasaki.
This is the sub-heading.
On July 20, Kawasaki Motors, a member of the Kawasaki Heavy Industries Group, conducted the world’s first public demonstration run of a hydrogen ICE (internal combustion engine) motorcycle by a mass-production motorcycle manufacturer at Suzuka Circuit in Suzuka City, Mie Prefecture, Japan.
These three paragraphs outline the demonstration.
The hydrogen ICE motorcycle was designed and built as part of research that began in March 2023, with test runs starting this year, culminating in the public demonstration run. Mounted in the machine is a hydrogen engine based on the 998 cm3 In-Line Four Supercharged Engine found in Kawasaki’s Ninja H2 motorcycle, with modifications made to allow direct injection of hydrogen fuel into the cylinders. The motorcycle’s chassis was designed to accommodate hydrogen fuel canisters and a hydrogen fuel supply system on-board.
Hydrogen ICE motorcycles run on hydrogen combustion, producing the rumble and pulsating sensation that riders enjoy when twisting the throttle, while emitting mainly water.
As part of their carbon neutral initiative, Kawasaki Motors is currently conducting research and development with the aim of realizing a functioning hydrogen ICE motorcycle*2 as one carbon-neutral option for riders in the early 2030s.
Some people will prefer quiet, hydrogen-fuel cell motorcycles.
Lawnmowers And Other Small-Engined Equipment
As hydrogen fuel spreads around the countryside, I can see lots of rural equipment using it for motive power.
Liverpool Street Station Gets Polka Dot Sculpture
The title of this post, is the same as that as this article on the BBC.
This is the sub-heading.
A huge artwork made up of silver polka dots has been unveiled outside Britain’s busiest railway station.
These are the first two paragraphs.
Infinite Accumulation is Japanese artist Yayoi Kusama’s first permanent public artwork in the UK and her largest permanent public sculpture.
Funded by British Land and the City of London Corporation, it is the final artwork commissioned and installed by the Crossrail Art Programme for the Elizabeth line.
I took these pictures today.
Note.
- The area is getting to be a bit of a sculpture park, with other sculptures and plaques.
- All are protected by the City of London’s distinctive bollards. See The City Of London’s Soldiers for more pictures.
- The new sculpture, is probably worth nicking, with all that stainless steel.
- Liverpool Street station is a Grade Two Listed Building.
- I shall be adding extra pictures here. I shall be taking some at sunset.
I do like the new sculpture and the way it fits with the surrounding buildings.
SeaTwirl Partners With Local Firm To Bring Vertical-Axis Floating Wind Turbine To Japan
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Sweden-based SeaTwirl has signed a Memorandum of Understanding (MoU) with Sumitomo Corporation Power & Mobility (SCPM) to promote its vertical-axis offshore floating wind turbine in the Japanese market.
These two paragraphs detail the responsibilities.
Under the MoU, SCPM will be responsible for identifying, marketing, negotiating, and contracting potential clients.
The Swedish company will be in charge of promoting and offering the products and services to potential clients.
Note.
- In SeaTwirl And Verlume Join Forces To Drive Decarbonisation Of Offshore Assets, I talk about their MoU with Verlume.
- In SeaTwirl, Kontiki Winds To Explore Powering Oil & Gas Assets With Floating Wind, I talk about their MoU with Kontiki Winds.
SeaTwirl either likes using Memoranda of Understanding (MoU) or their technology is very good.
The article says this about the applicability of SeaTwirl to Japanese waters.
Japan has over 4,000 islands, and according to the Global Wind Energy Council (GWEC), it has approximately 128 GW of fixed-bottom offshore wind potential and 424 GW of floating offshore wind potential.
SeaTwirl said that its vertical-axis wind turbine is well-suited for the conditions in the Japanese offshore environment with its robust and flexible design and high serviceability.
That certainly looks to be a good match and I wonder, if this could end up as a three-way co-operation, with the inclusion of Verlume’s underwater batteries.
Will SeaTwirl and Sumitomo target other island nations or those with lots of islands like Croatia, Greece, the Caribbean, Italy, Micronesia and the Philippines?
Japan Expands Offshore Wind Development Into Exclusive Economic Zone
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Japanese Government has passed an amendment to the “Act on Promoting the Utilization of Sea Areas”, expanding the area for setting up offshore wind to the Exclusive Economic Zone (EEZ).
These two paragraphs give more details.
The Japanese government aims to deploy 10 GW of offshore wind capacity by 2030 and 30-45 GW by 2040, including floating wind, as part of its target to reach net-zero emissions by 2050.
The new legislation would allow wind farms to be installed further out to sea from current territorial and internal waters, according to a joint statement by the government, the Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism.
The Japanese seem to have devised a simple bid process, that gives rights to generate electricity for thirty years.
But then as a Director of Lockheed told me thirty years ago, the Japanese don’t have the same high levels of lawyers that the US, UK and other countries have, so they can move a lot faster and are easier to do business with.
This Wikipedia entry is entitled Wind Power in Japan.
This is the opening paragraph.
In Japan’s electricity sector, wind power generates a small proportion of the country’s electricity. It has been estimated that Japan has the potential for 144 gigawatts (GW) for onshore wind and 608 GW of offshore wind capacity. As of 2020, the country had a total installed capacity of 4.2 GW.
From the potential of 608 GW of offshore wind capacity, it looks like Japan is in a very similar position to the UK and the Japanese can also reap the wind.
Footbath Train Launched To Serve Hot Springs Resort
The title of this post, is the same as that of this article on Railway Gazette.
This first two paragraph give full details.
Private train operator Kintetsu has modified one of its electric multiple-units to operate luxury tourist services between Nagoya and Yunoyama-Onsen, a hot springs resort in the Suzuka area of outstanding natural beauty.
Branded Tsudoi, the three-car EMU has been retrofitted with outward-facing longitudinal seats backing onto a central aisle. It can carry up to 88 passengers, although the operator intends to limit ridership to 56.
It looks very up-market!
Japanese Offshore Wind And Battery Storage Project Begins Commercial Operation
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
On 1 January 2024, JERA and Green Power Investment Corporation (GPI) began commercial operations at the 112 MW Ishikari Bay New Port Offshore Wind Farm in Japan, which they own through Green Power Ishikari GK, a special-purpose corporation (SPC).
The most significant thing about this wind farm, is that it has been designed from Day One to operate with a battery, which is detailed in the last paragraph.
The project also features a battery storage component with 100 MW x 180 MWh of capacity.
Note that the output of the battery is 89 % of that of the wind farm. Is that the ideal ratio between battery and wind farm capacities?
Conclusion
Because of my training, as an Electronics and Control Engineer, I belief that most renewable energy can be smoothed with the adding of a battery.
Building Inside Mountains: Global Demand For Pumped Hydroelectric Storage Soars
The title of this post, is the same as that of this article on Construction-Europe.
This is the sub-heading.
Pumped hydroelectric storage plants around the world have been secretly storing electricity in remote mountain lakes for the last century. But the switch to renewable energy sources is prompting a surge in new construction.
These two paragraphs introduce the article.
Looking out over the ragged beauty of the Scottish Highlands, Coire Glas, a horseshoe-shaped valley holding a clear mountain lake above the shores of Loch Lochy, seems like an unlikely spot to build a megaproject.
In this remote location, surrounded by clumps of pine trees, a team of construction workers from contractor Strabag are tunnelling their way through the rock which they hope will form part of a vast new power storage facility.
The article is a must-read that talks about pumped storage hydroelectricity in general and SSE Renewables’s 1500MW/30 GWh Coire Glas power station in particular.
The Future Of Pumped Hydroelectric Storage
These two paragraphs from the article give a glimpse into the future.
According to the International Energy Agency, global pumped storage capacity is set to expand by 56% to reach more than 270 GW by 2026, with the biggest growth in India and China.
Current pumped storage megaprojects currently in construction include the Kannagawa Hydropower Plant near Minamiaki in Japan which when fully completed in 2032 is expected to have a total installed capacity of 2,820MW; and Snowy Hydro 2.0 in New South Wales, Australia, which is currently expected to complete in 2028.
Note.
- I can count two Indian and ninety Chinese systems under construction. All have a capacity of upwards of one GW.
- The Kannagawa Hydropower Plant appears to be the largest with a capacity of 2.82 GW. The Japanese are keeping quiet about the storage capacity.
- The Snowy Hydro 2.0 has a capacity of 2 GW and a storage capacity of 350 GWh.
- The Wikipedia entry for Snowy Hydro 2.0 states that it is the largest renewable energy project under construction in Australia.
Against this onslaught of massive systems, SSE Renewables are pitching the 1500MW/30 GWh Coire Glas and the 252MW/25 GWh Loch Sloy systems.
Pumped hydroelectric storage will have a big part to play in decarbonising the world. Even in little old and relatively flat UK.
Japanese Companies To Invest GBP 14.2 Billion In UK’s Offshore Wind, Green Hydrogen
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Japanese giants Marubeni Corporation, Sumitomo Corporation, and Sumitomo Electric Industries have committed to investing a total of GBP 14.2 billion (approximately EUR 16.3 billion) in offshore wind and green hydrogen projects, and the offshore wind supply chain in the UK
These two paragraphs add a bit of context and flesh to the deal.
Ahead of the UK Prime Minister’s business reception in Tokyo on 18 May, the UK government announced that leading Japanese businesses have committed to invest GBP 17.7 billion (approx. EUR 20.3 billion) in businesses and projects across the UK.
Of this, GBP 14.2 billion has been committed by Marubeni, Sumitomo and Sumitomo Electric for projects in offshore wind, green hydrogen and offshore wind supply chain.
SSE’s Berwick Bank Wind Farm will have a capacity of 4.1 GW and is budgeted to cost just short of £18 billion. Doing a quick calculation, indicates that £14.2 billion would only finance £3.23 GW of offshore wind.
But the Japanese say they will invest in offshore wind, green hydrogen and offshore wind supply chain. Investing in the offshore wind supply chain, would surely attract more money as the developers placed orders for foundations, floaters, electrical gubbins and support vessels.
Note.
- In Japanese Giant Sumitomo Heavy Invests In Liquid-Air Energy Storage Pioneer, I wrote about Sumitomo’s investment in English energy storage. company; Highview Power.
- Electrolyser company; iTM Power has also sold a 1.4 MW electrolyser to Sumitomo and signed an agreement over American sales with another Japanese company.
I can see other similar co-operative deals being developed. Possible areas could be cables, transformers and support vessels.
