Underground Sun Storage 2030 - Start

For more than ten years, RAG Austria AG has been working with hydrogen as an energy source in order to store renewable energy on a large scale and seasonally. The company develops leading edge energy technologies related to green gas and hydrogen that partner renewables. This enables RAG to play a vital role in attaining Austria’s ambitious climate goals, and in the sustainable stewardship of the country’s raw material and energy supplies. Our goal is to provide our customers with safe, efficient, environmentally friendly and affordable energy and gas storage services – sustainably and responsibly.

The business focus is market driven storage, conversion and conditioning of energy in gaseous forms. The company has gas storage capacity of about 6.3bn cubic metres (cu m) of natural gas, or about 6% of total capacity in the EU. A large part of RAG’s gas fields have already been converted into storage facilities, which can rapidly discharge stored energy in large quantities on-demand. In this way RAG is delivering on its vision of “sustainable energy mining”, and decisively reinforcing security of supply in Austria and Central Europe.

Project Goals

Field test and operational experience for field testing and in-depth know-how of hydrogen behaviour in natural gas reservoirs.

"Hydrogen is the missing piece of the puzzle for a completely CO2-neutral energy system: it can be produced in a climate-neutral way, used directly in industry, produce environmentally friendly heat and electricity and represent a fuel of the future. But the decisive factor is its large-volume storage and transportability in the existing almost invisible gas infrastructure. Only in this way will we have sufficient and, above all, demand-oriented green energy available even in times of low sun and low wind," says RAG CEO Markus Mitteregger, emphasising the importance of energy storage in geological gas reservoirs and its distribution.
