Start of the project "Underground Sun Storage 2030"
Start of the project "Underground Sun Storage 2030"
In the lead project "Underground Sun Storage 2030" (USS 2030), the safe, seasonal and large-scale storage of renewable energy in the form of hydrogen in underground gas reservoirs is being developed. In addition, all partners involved in the project will jointly gain valuable technical and economic knowledge for the development of a secure hydrogen supply.
In this research project, the only one of its kind in the world, renewable solar energy is converted into green hydrogen in a climate-neutral way by means of electrolysis and stored in a pure form in former natural gas reservoirs. Until 2025, interdisciplinary technical-scientific investigations for the energy future will be carried out under real conditions at a small former natural gas reservoir in the municipality of Gampern (Upper Austria) under the leadership of RAG Austria AG together with the project partners. A customised research facility will be built for this purpose.
Hydrogen from sun and wind will be produced in Ukraine and stored for seasonal demand in Central Europe in the future
In order to accelerate and ramp up the production of green hydrogen for Europe, which is an absolute must have for a climate-neutral European energy supply, the international industry partnership consisting of Bayerngas GmbH, bayernets GmbH, Eco-Optima LLC, Open Grid Europe GmbH and RAG Austria AG has designed the "H2EU+Store" project.
"H2EU+Store" will on the one hand create the necessary capacities for renewable electricity and hydrogen production in Ukraine and on the other hand the expansion of storage volumes in Austria and Germany , accompanied by adaptations in the area of gas transport to Central Europe.

Sustainable storage for the renewable energy system of the future
From December 2020, the “Underground Sun Conversion – Flexible Storage” (USC-FlexStore) project will investigate seasonal storage of large quantities of renewable energy to be made available year round.
This innovative international project is aimed at developing a seasonal, high-volume transformation and storage solution for erratic renewable generation. Energy will be stored safely in gaseous form in underground facilities at depths of over 1,000 metres.
The aim of the project is to take RAG Austria AG’s patented “Underground Sun Conversion” (USC) technology (which involves methanation of CO2 and green H2) to the next level, and to design services based on it. Field tests are planned at RAG’s research facility in Pilsbach (Upper Austria).
As part of Austria's critical infrastructure, RAG Austria AG is responsible for the reliable supply of energy around the clock. We are optimally prepared to ensure secure and reliable supply of gas for electricity, heat and mobility at all times.
Secure operation at RAG Austria AG
RAG Austria AG takes its responsibility towards its own employees as well as the entire Austrian society very seriously and therefore takes organizational measures to protect its employees and to maintain secure and reliable operations. RAG Austria AG is in constant communication with authorities and occupational health professionals.
Critical Infrastructure
Internal measures have been taken to ensure that the necessary supply of energy continues to be guaranteed around the clock. Only persons who are absolutely necessary for operation are allowed to remain on the company premises. Individual home office agreements have come into force. Appropriate precautionary measures have also been organized for possible quarantine cases.
„Zukunft Grünes Gas“: The new platform for a sustainable, secure and affordable energy system transformation
„Zukunft Grünes Gas“: The new platform for a sustainable, secure and affordable energy system transformation
Since 10th November 2020, the new "Zukunft Grünes Gas" platform of the "Österreichische Vereinigung für das Gas- und Wasserfach" (ÖVGW) and the "Fachverbands der Gas- und Wärmeversorgungsunternehmungen" (FGW) has been online. The new homepage focuses on information about green gas.
A sustainable, safe and affordable energy system transformation will only be possible with climate-friendly green gas. In the years ahead, domestic gas suppliers want to put this change into practice. Green gases such as biogas and hydrogen will become more important in the future.
In order for the energy system tranformation to succeed, all existing potentials of green energy in Austria are needed.
Gas currently accounts for more than 20 percent of total energy demand and stands for 100 percent supply security. Replacing this energy source is neither technically nor economically possible. The solution: green gas that can be used just like the gas we are used to today.
In addition to the use of traditional natural gas, RAG is intensively focusing on "Green Gas" technologies, such as renewable gas from electrolysis of water and renewable natural gas produced from it. The "Underground Sun Storage" and "Underground Sun Conversion" projects open up the unique possibility of storing this hydrogen or natural gas, which is produced from renewable energies such as sun and wind, seasonally, in large volumes and CO2-neutral underground so that it can be extracted when it is needed. "Green Gas" is the pioneer of the energy turnaround and has enormous potential for a sustainable, affordable energy supply in the future.
In the category „university research“ the project „Rechargeable GeoBatteries - Microbial Production and Storage of Renewable Natural Gas in Exploited Reservoirs“ has been honoured with the Houska Award by a professional audience. This project was conducted by Prof.Dr. Andreas P. Loibner (BOKU - University of Natural Resources and Life Sciences, Vienna) and provides the basis for the “Underground Sun Conversion“ project.
Transportation plays an essential role in a functioning economy.
All medium and long term forecasts predict growth in the volume of road traffic, especially heavy goods traffic. Global, European and national climate protection targets aim at a reduction in emissions produced by vehicles. The use of gas as a fuel can make a major contribution to achieving these targets, since vehicle traffic contributes about 45% of emissions..
Work begins on construction of test facility in Pilsbach, Upper Austria
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.
