Construction underway on ‘first’ offshore project that could produce liquid air and hydrogen instead of electricity

Construction of a 175MW wind farm which could be the first offshore project to produce liquid air and hydrogen instead of electricity has moved from R&D to construction in Florida, US.

Scheduled for completion in 2028, Keuka Energy, behind the plans, said it is expected to produce the first renewable utility-scale stored energy.

Once completed, the system will be capable of storing 330,000m³ of liquid air and support a 235,000 horsepower wind farm comprised of 14 RimDrive^TM wind machines.

Welcoming the news, Keuka CEO Herbert Williams said, “Even though we sacrifice about 50% of our shaft horsepower to produce liquid air and/or hydrogen, the low capital cost of the RimDrive^TM system combined with mechanical liquefaction – without electricity – puts it at a lower levelised cost of energy (LCoE) than natural gas.”
