Underground Sun Conversion - Start

Underground Sun Conversion research project – the only one of its kind in the world – headed by RAG

A press conference for the Underground Sun Conversion project – the only research project of its kind anywhere in the world – was held on 2 March 2017. In attendance were Jörg Leichtfried, Austrian Minister for Transport, Innovation and Technology, Theresia Vogel, Managing Director of the Austrian Climate and Energy Fund, RAG CEO Markus Mitteregger, and Professor Andreas Loibner of the University of Natural Resources and Applied Life Sciences, Vienna.

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.

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.
