Underground Sun Conversion - Start

Work begins on construction of test facility in Pilsbach, Upper Austria

Pilsbach / 1st March 2018. Construction of the Underground Sun Conversion test facility at Pilsbach in Upper Austria will start in early March at the same site where the forerunner project, Underground Sun Storage, was successfully carried out. “What we have achieved in the laboratory at the University of Natural Resources and Applied Life Sciences will now be tested in situ. Based on the research results so far, we are confident that we will soon be able to harvest natural gas, produced by us from solar energy, from the Pilsbach natural gas reservoir,” explained Mitteregger.

Geological history in fast motion: renewable natural gas produced from solar power and water, 1,000 metres underground

The successful Underground Sun Storage project, which focused on the storage of wind and solar energy in naturally formed gas reservoirs, is to be taken to the next stage.

Building on the research conducted so far, for the first time the Underground Sun Conversion project will enable production of natural gas directly within a gas reservoir using a microbiological process initiated specifically for this purpose by RAG, and to store it in the same reservoir.
This innovative method is unique worldwide, and recreates the natural process by which gas originates, but shortens it by millions of years – geological history in fast motion.
