It is proposed to convert photovohaic membrane water electrolyser （PEMWE） （PV） energy to hydrogen energy by proton exchange for long-term energy storage. This hydrogen production system consists of PV modules, PEMWE, hydrogen tanks, hydrogen compressor and so on. The mathematical models of the key components are developed, and the system efficiency model is developed too. The simulation is performed by using the Matlab environment, and the operating performance of the PV hydrogen system is analyzed. Simulation resuhs show that the PEMWE can convert the PV energy into hydrogen as 70% system efficiency in variable mower mode.
