Design Study for the European Underground Research Infrastructure related to Advanced Adiabatic Compressed Air Energy Storage


By bringing together the leading researchers and research organisations with long-term experience in the areas of thermal storage design with researchers who will introduce very new and innovative aspects of underground construction including materials, excavation methods and environmental impact, an advanced, integrated and therefore cost-efficient concept and approach of building AA-CAES caverns resistant to high temperature and high pressure will emerge.

Role within the RICAS2020 Consortium:
Project Management

MUL represents expertise from the highest available European and international level especially in relation to underground construction technologies. MUL will be responsible for the legal, approval, institutional and financial concept of RICAS2020, as the university disposes of an existing research infrastructure located at the geographical centre of Europe which will offer synergies for RICAS 2020 (a road and rail network, existing supply lines for electricity, water and sewage). MUL will
further contribute to the dimensioning of the AA-CAES cavern by numerical simulation and will furthermore be responsible for the Project Coordination and Management.
