中文摘要	Water electrolysis coupled with an efficient and clean primary energy source is an ideal large-scale hydrogen production technology. A model was developed to predict the efficiency of a water electrolysis system for hydrogen production based on the overall efficiency of an alkaline electrolysis system, a solid polymer electrolyte (SPE) system, and a solid oxide electrolysis cell (SOEC) system. The results show that both the electrolysis efficiency, 56%, and the overall efficiency, 25%, are very low. The electrolysis efficiency, 76%, of the SPE system is improved, the overall efficiency, 35%, is still low. However, the electrolysis efficiency of the SOEC is more than 90% and the overall efficiency is over 55%, both are much higher than the other systems. The overall efficiency of a high-temperature gas-cooled reactor coupled with an SOEC system is the highest among all existing water electrolysis systems.
