Underground Sun Storage 2030 - Start

Vienna University of Technology

The Vienna University of Technology is Austria's largest research and educational institution in the field of technology and natural sciences. More than 4,000 scientists are researching "technology for people" in five main research areas at eight faculties. The content of the studies offered is derived from the excellent research. More than 27,000 students in 55 degree programmes benefit from this. As a driver of innovation, TU Vienna strengthens the business location, facilitates cooperation and contributes to the prosperity of society. The participating institutes have many years of project experience and their research focus in the topics of renewable energies, circular economy and hydrogen.

Project goals

At the TU ICEBE, a highly flexible, innovative hydrogen treatment process for the discharged storage gas is to be tested and dimensioned on a laboratory scale. The findings will serve as the basis for the design and construction of a demonstration plant directly at the gas storage facility. AM TU EEG, various medium-term electricity supply scenarios are to be modelled and seasonal operating strategies for the electrolyser developed from them.

"By participating in this Austrian lighthouse project, the researchers at TU Wien are pleased to make an important technological contribution to the European Green Deal and the goal of developing hydrogen as a central element of a decarbonisation strategy for the energy sector and the entire Austrian economy."
