New York — As liquid air energy storage company Highview Power prepares to launch two US projects this year, an official said Thursday, the company has teamed up with engineering firm Citec to help scale its storage facilities from 50 MW/500 MWh to multiple GWh.
“We will be starting two projects between 50 MW and 100 MW in the US this year,” Javier Cavada, Highview CEO, said in a phone call.
Though Cavada could not discuss specific locations or customers, he said Highview is looking at the wind corridor that runs through the Midcontinent Independent System Operator’s territory, as well as California, Texas and New York.
“It’s ideal to mix the technology with renewable generation, but it can be located anywhere,” Cavada said.
UK-based Highview Power has chosen Finland-based Citec as its engineering partner to help Highview modularize its GW-scale cryogenic energy storage system, according to a Wednesday statement. Highview said Citec will help it “easily and cost-effectively” scale the capacity of its plants up or down.
The economy of scale “is steep” so the larger the system the cheaper it gets, Cavada said.
The technology uses liquid air as the storage medium and can currently deliver 20 MW/80 MWh to more than 200 MW/1.2 GWh of energy. Air is cooled and stored as a liquid, then converted back to a gas to generate energy that powers turbines producing electricity.
In April 2018, Highview launched a grid-scale demonstrator plant that converts waste heat from landfill gas engines at the Pilsworth Landfill in Bury in the UK into power.
