Industrial gases specialist Messer has supported a study of energy storage using liquid air, which was presented by the UK’s Centre for Low Carbon Futures (CLCF) at a conference in London earlier this month.

The use of liquid air for grid-based energy storage could increase energy security, cut greenhouse gas emissions and create an entirely new industry.

Liquid air is a novel energy storage solution based on proven technologies such as air liquefaction and separation for the production of nitrogen or oxygen for industrial use. According to the study, which was carried out by economists and scientists, it could play an important role in the efficient use of low carbon energy sources.

For almost 100 years, Messer has been a specialist in liquefying air through compression and cooling as part of the production of industrial gases such as oxygen, nitrogen and argon – gases that are as important as water and electricity in many manufacturing processes.

Experts from the energy sector met at Messer in Bad Soden to discuss electricity storage with liquid air – the results of this informed the study. Messer is continuing to work on this with its British partner Highview, who invented the technology.

“I am delighted to see the level of excitement that the possibilities of cryogenic technologies have created across such a broad swathe of experts from academia, energy and industry,” said Tim Evison, who is in charge of Business Development at Messer in Bad Soden.
