How long can energy be stored in a refrigeration system?
In principle the energy can be stored indefi nitely as long as the cooling system is operational, but longer storage times are limited by the energy demand of the refrigeration system. Large SMES systems with more than 10 MW power are mainly used in particle detectors for high-energy physics experiments and nuclear fusion.
Which EES systems are suitable for short and medium discharge times?
EES systems for short and medium discharge times cover wide ranges of rated power and energy density. Several mature EES technologies, in particular FES, DLC and battery systems, can be used in these ranges. PHS is the only currently feasible large-capacity EES for medium discharge times; further development in CAES is expected.
