This article demonstrates that Cryogenic Energy Storage (CES) systems benefit from a high round-trip efficiency, applying cogeneration concepts to the charging and discharging operating regimes. CES systems are an emerging technology that can mitigate the power grid instabilities in an adverse scenario of high penetration of intermittent sources.
Cryogenic technologies are commonly used for industrial processes, such as air separation and natural gas liquefaction. Another recently proposed and tested cryogenic application is Liquid Air Energy Storage (LAES). This technology allows for large-scale long-duration storage of renewable energy in the power grid.
Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
A cryogenic energy storage (CES) system powered by a geothermal power plant is proposed. (2015), first pilot scale power plant for liquid energy storage reached a round-trip efficiency of only 8%.
