Critical factors of high-pressure hydrogen compression in hydrogen technologies

Abstract

Hydrogen technology is connected with many problems occurring during storage, liquefaction, distribution and utilization of hydrogen. The economy of all these processes is affected by mediumpressure and high-pressure compressors efficiency, which is with regard to thermodynamic properties of hydrogen function namely of their working space leakage. An experimental study of these phenomena was used to proposition of mathematical model describing the effect of reflux from working space on compressor efficiency.
