About Us

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.

Our Vision

phelas wants to make a very simple vision reality:
We want to make 100 % renewable electricity a “no-brainer” everywhere on this planet.

A strong Team working together to achieve a common goal

The phelas team works together on three main areas. Justin Scholz with over six years of start-up experience and Christopher Knoch with five years of professional experience as a management consultant work in the areas of business strategy & development, financing, recruiting and networking. Leon Haupt brings four years of professional experience in the energy sector and specialises in energy storage as a project manager. He is responsible for the technical-economic modelling as well as the development of business models for energy storage. Three other team members are driving the development, planning and implementation of the demonstrator and pilot plant: Dr. Pit Sippel has many years of experience in setting up and designing experiments, as well as extensive knowledge in the field of energy storage. Dr. Masoud Ghods, a renowned ex-NASA-project scientist, has in-depth knowledge in design, process modelling and the application of artificial intelligence in engineering. Florian Kaufmann contributes know-how in the field of cryogenic air separation and steady-state and dynamic process simulation. As a team, phelas is characterized by a strong team spirit as well as the common vision.
