phelas GmbH

Phelas develops an energy storage system that works with liquefied air. In this way, electricity generated from renewable sources is to be kept available sustainably and decentrally and is available around the clock.

The aim is to achieve an output of 1.2 megawatts per unit and a storage volume of about 2 megawatt hours. The cost of electricity storage per kilowatt hour is expected to be 5 cents. The founders see the advantages of their process in particular in the lifetime of their plants of 20 years as well as in the more than 10,000 charging cycles. Other advantages: they do not need toxic materials and use recyclable material, which they source locally and – like the steel required – in Europe.
