Company secures CHF 3 million for compressed air energy storage system
Green-Y Energy AG has successfully completed a financing round of 3 million Swiss francs, led by Swiss Capital Global Impact Fund AG. The company from Hasle near Burgdorf plans to use the funds to optimize and market its innovative compressed air energy storage technology. This technology stores photovoltaic power and enables buildings to be supplied with heat and cold. A pilot plant with a capacity of 100 kilowatt-hours was successfully commissioned in 2023.
Green-Y Energy AG has successfully completed a financing round led by Swiss capital Global Impact Fund AG totalling CHF 3 million. The company, which specialises in compressed air energy storage and is based in Hasle near Burgdorf, intends to use the additional capital to further optimise its innovative storage technology and drive forward the marketing of the systems, CEO Rafik Barhoumi was quoted as saying in a press release. The solution is considered to be particularly sustainable as it uses compressed air to store photovoltaic electricity and also enables the supply of heating and cooling in buildings and processes.
After a four-year development phase, a pilot system with a total capacity of 100 kilowatt hours was successfully launched in 2023, according to the press release. This can be used to optimise self-consumption in commercial areas. In residential and office buildings, the system could support space heating, water heating and cooling. Industrial companies could utilise the heat and cold generated in production processes.
The system makes “economic and ecological sense if the storage of electrical energy is combined with the utilisation of heat or cold. This is why compressed air storage systems are particularly suitable for neighbourhoods, larger office buildings and industry,” says Christian Ochsenbein, an expert in storage technologies and head of the Swiss Battery Technology Center.
