摘要: Abstract Hydrogen production by way of methane steam reforming based on solar energy is a promising means harvesting and storage. In this work, concept solar-driven thermochemical hydrogen derivation alternating carbon dioxide permeation membranes proposed, which capable driving reaction towards virtual completion isothermally in the temperature range 400-700 °C. Thermodynamic analysis performed one-dimensional model reactor consisting alternate H2 CO2 membranes. At 400 °C, both conversion rates water can reach 99.9%, while solar-to-fuel efficiency 61.7% when solar-to-electricity 15%. Major advantages approach include high efficiency, isothermal continuous operation low theoretical penalties for separation. This study brings new insights into efficient low/mid-temperature fuel production.
