Plate heat exchangers of different types are used along the entire value chain of the hydrogen economy. They are used both in processes for generating electricity from renewable energy sources and in the production of hydrogen by means of electrolysis, and also in the water treatment that is sometimes required for this.
The temperature of air tends to rise during compression, and the rise in the air internal energy is wasted during the later storage period as the compressed air cools back to ambient temperature. The present study focuses on designing an interrupted-plate heat exchanger used in a liquid-piston compression chamber for CAES.
Power-to-Gas (P2G) is a viable technology for renewable energy storage. In one of its preferred configurations, a hot gaseous mixture of H 2 O and CO 2 is fed to a high temperature electrolysis module (SOEC) and gets converted to CO and H 2, which are subsequently converted into methane in a methanation module.
