The conventional cold energy storage systems which can be used for LNG cold energy utilization include liquid air system, liquid carbon dioxide system, and phase change material (PCM) system. Using LNG to cool the compressed air into the liquid air is one route [ 117 ].
So liquid hydrogen is what it sounds like, it''s liquid hydrogen it goes on as a liquid. Cryo-compressed is very cold, but it goes on as a super-critical gas and the temperature can vary. We''ve looked at kind of different options there ranging from 300 all the way up to 700-bar, even higher. So kind of the difference there is dormancy.

Liquid air energy storage (LAES) is a large-scale physical energy storage system with high energy storage density. At present, the coupling matching regulation mechanism of the cold and thermal cycles is unclear under off-design conditions, which makes the stable and efficient operation of the LAES system difficult.
The present paper addresses an experimental investigation of the cold storage with liquid/solid phase change of water based on the cold energy recovery of Liquefied Natural Gas (LNG) refrigerated vehicles. Water as phase change material (PCM) was solidified outside the heat transfer tubes that were internally cooled by …
During the discharge cycle, the pump consumes 7.5 kg/s of liquid air from the tank to run the turbines. The bottom subplot shows the mass of liquid air in the tank. Starting from the second charge cycle, about 150 metric ton of liquid air is produced and stored in the tank. As seen in the scope, this corresponds to about 15 MWh of energy storage.
Based on the technical principle of the CAES system, the low-temperature liquefaction process is added to it, and the air is stored in the low-temperature storage tank after liquefaction, which is called liquid air energy storage (LAES) [17].LAES is a promising large-scale EES technology with low capital cost, high energy storage density, long …
