Spain may host 2 GWh of liquid air storage


From pv magazine Spain

Highview Power, a UK-based provider of long-term energy storage solutions, is developing several energy storage projects throughout Spain, with an aggregate capacity of up to 2 GWh and an estimated investment of about $1 billion.

The projects will be developed with the support of a consortium of investors, including Spanish engineering services provider TSK Ingeniería y Electricidad S.A. and Spain's Center for Energy, Environmental and Technological Research (CIEMAT). Highview Power plans to develop up to seven liquid air storage projects with a capacity of  50 MW / 300 MWh each in Asturias, Cantabria , Castilla y León and the Canary Islands.

In February, Highview Power announced the closing of a $70 million funding round and a portfolio of 4 GWh liquid air storage projects in the United States, Europe and Latin America. TSK is also among the investors.

The so-called Cryobattery technology developed by the company uses liquid air as the storage medium and offers critical network stability services such as synchronous inertia, short-range circuitry, and dynamic voltage control.

According to Highview Power, Cryobattery plants have a performance equivalent to that of thermal and nuclear power plants. “Highview Power's cryogenic storage technology is cost-effective, scalable, clean, and has a long shelf life,” it said in a statement. “It is the only long-term energy storage solution available today that is traceable and offers multiple GWh of storage.”

In 2019, Highview Power and TSK announced the creation of a joint venture, Highview TSK, which planned the development of different projects in Spain, the Middle East and South Africa between 2019 and 2022.

The Spanish government's national energy storage strategy aims to reach 20 GW of storage capacity in 2030.
