phelas - 100 percent renewable energy through innovative liquid air energy storage

The phelas-team is developing Aurora, a standardized, modular, mass-manufactured and cheap large-scale electrical storage system that uses electricity during the charging process to cool air down to cryogenic temperatures and thus liquefy it. For discharging, the cryogenic liquid is heated and thus evaporated. The strong increase in volume and pressure is again used to generate electricity.

With this approach, phelas aims to completely eliminate the need for fossil electricity production. The replacement of coal and gas plants necessitates large electricity storage capacities. Renewable energy sources provide energy only when the sun shines and the wind blows - which is not always. Consequently, energy storage is needed to enable the shift for energy production from renewable sources.

To achieve this ambitious goal, the phelas team works together on three main areas. Justin Scholz and Christopher Knoch are working on corporate and business development, funding, recruiting and networking. Leon Haupt is in charge of technical-economic energy storage modeling and business model development for energy storage. PhD Pit Sippel and Florian Kaufmann (in his free time) together with advisor and chemical engineering expert PhD Nick Stuckert are pushing forward the chemical process engineering and development, planning and implementation of the demonstrator and the pilot plant. As a team, phelas is characterized by a strong team spirit as well as the common vision: To have a 100% renewable electricity grid be a “no brainer”. The team identified storage as the missing puzzle piece – and is building exactly this piece.

With the financial help of public institutions, phelas has already been able to develop and construct a demonstrator in the laboratory of the Technical University Munich. Moreover, the team is preparing to protect their intellectual property as well as simulating use cases. They are on track for the next target: pre-seed funding, with which the prototype will be completed, and the technical concept finalized.

The product Aurora has a very long lifetime of projected 20+ years. As a newcomer, this is a period for which many customers will demand an assurance that the claims regarding endurance are valid. Together with Munich and ERGO, phelas plans to work on feasible insurance solutions for the technology.
