Oman Set For Next Frontier In Energy Storage
The title of this post is the same as that of this article on the Times of Oman.
This first paragraph introduces the story.
Oman’s solar story is already being written. Manah, Ibri II, and the next wave of solar IPPs moving through procurement have placed the Sultanate firmly among the region’s renewable leaders. The next chapter, the one every solar-rich nation is racing to author, is about the long-duration energy storage technology that powers the grid after sunset. Lithium-ion batteries handle the first few hours effectively. What comes after is the harder problem, and it is increasingly being solved by a technology called Liquid Air Energy Storage, or LAES: a technology that aligns naturally with Oman’s industrial base.
The article then describes how the technology to handle LAES technology aligns with all their expertise in handling liquified natural gas.
This paragraph outlines Oman’s expertise in cryogenic engineering.
Oman’s natural advantage in this race deserves far more attention than it has received. Cryogenic engineering, the discipline of holding substances at extraordinarily low temperatures without losing them, is the most demanding part of any LAES plant. It is also the foundation of the LNG export business that has run out of Qalhat for a quarter of a century. The workforce that liquefies natural gas at minus 162 degrees Celsius is the same workforce that can liquefy air. The insulation expertise, the compressor specifications, and the maintenance discipline are all already here, refined over decades and built locally. Few nations possess this depth of capability as a domestic resource. Oman does.
If Oman have called this one right, then any nation with plentiful renewable resources, of solar, hydro, offshore wind or geothermal, should be looking at Liquid Air Energy Storage.
This is not the first time, that Liquid Air Energy Storage has been paired with LNG.
Highview Power are the UK pioneers of Liquid Air Energy Storage and on the Projects page of their web site, there is this section on Japan.
Our investment partner Sumitomo Heavy Industries (SHI), together with Hiroshima Gas, is developing a grid‑scale LAES demonstration plant in Hatsukaichi, Hiroshima. The 5 MW, four‑hour facility will use waste cold from an adjacent LNG terminal to enhance efficiency and sustainability, showcasing the flexibility of Highview’s modular LAES technology. The plant is scheduled to be operational in 2025.
In Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?, I describe how the Hiroshima plant held a completion ceremony on the 9th December, 2025.
Liquid Air Energy Storage and LNG may seem unlikely bedfellows, but when engineers share a few beers, joint projects seem to emerge.
