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


On the long run the big goal of the planned RICAS2020 research infrastructure is to bring AA-CAES very close to big cities and other large consumers of energy; thus it is essential to be able to

  • install the AA-CAES completely underground,
  • to design the necessary underground structures in a most economical way e.g. by reusing part of the tunnel/cavern excavation material directly in the cavern to store the heat and to build up the lining,
  • to excavate the underground structures in a safe way without producing significant amounts of vibrations and noise and dust.
