Energie 360 ° is working on a power-to-gas solution
Energie 360 ° is testing a patented storage solution for excess solar energy together with RAG Austria. Solar power is to be converted into hydrogen and stored underground together with CO2. Methane gas is produced there, which can be used in winter.
Energie 360 ° and the gas storage company RAG Austria are working on making solar energy available all year round. Both are jointly pursuing the innovative power-to-gas project Underground Sun Conversion – Flexible Storage . It started in December 2020 has a term of two and a half years and is supported by the European Commission promoted . Field tests are already underway at the RAG research site in Pilsbach, Upper Austria.
In this project, excess renewable energy, such as solar power in summer, is converted into hydrogen, explains Energie 360 ° in a press release . This is then stored together with carbon dioxide in natural underground storage at a depth of over 1000 meters. There, microorganisms combine hydrogen and carbon to form renewable methane gas. This energy can be used in the event of supply gaps, for example in winter. The advantage over pumped storage power plants or batteries lies in the much higher storage capacity and, at the same time, less surface area, according to Energie 360 °.
In Switzerland, the two companies cooperate with the University of Bern , the University of Applied Sciences in Eastern Switzerland and the Federal Materials Testing and Research Institute ( Empa ). "We are working together on the solution to one of the greatest challenges facing the energy system of the future: How do we advance volatile renewable energy sources such as sun and wind and at the same time offer year-round security of supply?", Says Andreas Kunz, Head of Energy Systems at Energie 360 °.
