TÜV AUSTRIA ensures safety at this unique demonstration plant for the storage of green hydrogen.
In this lead project, 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 deposits. The scale of the storage corresponds to the summer surplus of about 1,000 photovoltaic systems on single-family homes or 4.2 million kWh (4.2 GWh). In summer, this surplus energy is stored and in winter the green energy can be provided again in the form of electricity and heat.
Plant operator RAG AUSTRIA AG has been a customer of TÜV AUSTRIA for many years and also relies on reliable quality and safety for the future-oriented project “Underground Sun Storage 2030” (USS 2030) and commissions TÜV AUSTRIA with the acceptance test of the plant. “For RAG AUSTRIA AG, the cooperation with TÜV AUSTRIA is essential in order to guarantee the required highest safety standards. The special requirements in this project were fulfilled by the TÜV AUSTRIA specialists in a proven manner, competently and flexibly, to our complete satisfaction”. Werner Bogner, Team Leader Renewables & Decarbonisation / Green Gas Technology Department, summarises the cooperation.
Around two years after the start of the project, the system and storage tank of “Underground Sun Storage” were inspected with regard to electrical, pressure and control technology. TÜV AUSTRIA experts Ing. Daniel Wetsch, Dipl.-Ing. (FH) Florian Rainer and Dipl.-Ing. Oliver Lugmayr carried out the electrical system inspection and machine safety inspection on site. It was ensured that the machines comply with the requirements of the Machinery Directive (2006/42/EC) and, with regard to the electrical equipment, with the EN 60204 standard. Furthermore, TÜV AUSTRIA test engineer Dipl.-Ing. Leonhard Hofer checked the functional safety and engineer Dietmar Heimberger inspected the system with regard to pressure equipment aspects.
Targeting expertise in dealing with hydrogen
During the acceptance test, special attention had to be paid to the property of hydrogen as an extremely volatile element. This had to be taken into account especially during the pressure equipment test, as it had to be ensured that all seals and connection components, in particular, not only withstand the necessary high pressure – tested at up to 90 bar – but also do so in combination with H2. But also with regard to the avoidance of explosion hazards, the volatility of hydrogen had to be carefully considered. One focus of the inspection was on the machine in which the electrolysis, i.e. the conversion of water into hydrogen, takes place, in order to rule out the possibility of an H2 atmosphere developing here.
In this research project, interdisciplinary technical-scientific investigations for energy storage under real conditions are being carried out at a small former natural gas deposit in the municipality of Gampern (Upper Austria) under the leadership of RAG AUSTRIA AG together with the project partners. The aim is to jointly gain valuable technical and economic knowledge for the development of a secure hydrogen supply.
TÜV AUSTRIA’s expertise in hydrogen was put to optimal use in this project and makes an important contribution to the energy transition while maintaining security of supply.

New ISO requirement:
Climate change will be included in all management system standards
On 22 February 2024, IAF and the International Organization for Standardization (ISO) published a joint communiqué to highlight the publication of Climate Action Amendments to new and existing ISO management systems standards, in support of the ISO London Declaration. The intent is to ensure that Climate Change issues are considered by the organization in the context of the effectiveness of the management system, in addition to all other issues. TÜV AUSTRIA has summarized FAQ about the new regulations.

End-of-year remarks
Into the new year with optimism
Dr. Stefan Haas, CEO TÜV AUSTRIA Group
The Russian war of aggression has still not come to an end, we are witnesses to Israel’s fight against Hamas terror. Natural disasters, environmental pollution and much more cast a dim outlook on the future. So why are we actually optimistic about 2024?
