Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity

Cryogenic Energy Storage (CES) is one of the energy storage technologies, which stores energy in a material at temperatures significantly lower than the ambient temperature. The storage material can be solid (e.g., rocks) and liquids (e.g., salt solutions, ethylene glycol-water solutions, methanol, nitrogen, and air).
Hydrogen can be stored in the four types of pressure vessels. The choice of the storage is based on the final application which requires a compromise between technical performances and cost-competitiveness. H2 as industrial gas is stored in type I tanks, the pressure of which is from 150 to 300 bar (usually 200 bar).
