Abstract
Hydrogen is considered as the most potential energy carrier in the near future and can be produced from nuclear energy by several means. Lead-based reactor is one of the advance reactors in hydrogen production. In this paper, a novel feasible system of lead cooled reactor coupled with solid oxide electrolysis cells (SOEC) is presented, which is named China LEAd-based Reactor for Hydrogen production (CLEAR-H). By taking advantage of the chemically inert and high density of lead–bismuth eutectic (LBE), the concept of LBE-water direct-contact steam generator is proposed to supply high temperature (up to 600 °C) and low pressure (0.1–0.2 MPa) steam for SOEC stack without additional decompression devices. The results show that 47 tons hydrogen and 3000 tons oxygen-enriched air are obtained per day, and the thermal-to-hydrogen efficiency can reach about 39%.
