An Analysis of Hydrogen Production Via Closed-Cycle Schemes
A thermodynamic analysis and state-of-the-art review of three basic schemes for production of hydrogen from water: electrolysis, thermal water-splitting, and multi-step thermochemical closed cycles is presented. Criteria for work-saving thermochemical closed-cycle processes are established and several schemes are reviewed in light of such criteria. An economic analysis is also presented in the context of energy costs.
