Is Sumitomo Heavy Industries Highview Power Energy Storage System On line At Hiroshima?
From some work I did at ICI in the 1970s, 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.
Note.
- It looks like the battery has a capacity of 4 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.
Some of the systems, I mathematical-modelled for ICI could certainly have benefited from Highview’s technology.
