phelas GmbH

Founded in 2020, phelas develops and builds Liquid Air Energy Storages (LAES) for wind and solar energy. The team is currently prototyping a unique standardized, modular, mass-manufactured and cheap large-scale electrical storage system: Aurora. The system uses the proven concept of liquid air storage. During the charging process air is cooled down to cryogenic temperatures and thus liquified. For discharging, the cryogenic liquid is heated and thus evaporated. The strong increase in volume and pressure is again used to generate electricity. Based on this principle, the team has designed a new containerized storage system that makes LAES flexible, transportable and thus profitable for the first time. Renewable energies are on the rise globally. On the way to the transition to 100%, a sustainable and resource-efficient storage is the missing piece of the puzzle. The phelas team is building exactly this piece.
