The switch to renewable energies requires new ideas and concepts, which the ILK Dresden has intensively addressed in recent years. Explicitly, an energy storage system based on Liquid Air Energy Storage (LAES) was developed as part of a publicly funded project. This energy storage is based to a large extent on the principle of liquefied air, in which the processes for liquefaction and regasification are adapted to the requirements of the power storage. Integral parts of the liquid air storage system are various cold storages. The different cold storage tanks must be precisely coordinated with one another in order to generate stable operating
parameters regarding the efficiency of the overall process. The publication explains and describes constructive aspects and challenges in the implementation of these cold storages and in their entirety. Results of the material selection as well as thermal simulations and calculations will be introduced. Experimental results of the cold storage in the composite of the entire energy storage are presented as their benefits for similar facilities.
