Abstract: A novel solar-driven high-temperature co-electrolysis system is proposed, which consists of a solar photovoltaics module, a parabolic trough collector module, an ammonia-based chemical heat pump (CHP), and a solid oxide electrolyzer cell (SOEC) module. The ammonia-based CHP implemented with a hydrogen-permeant membrane reactor can upgrade solar heat. Numerical models to simulate the hydrogen-permeant membrane reactor, the SOEC, and the entire system have been developed. The models have been validated by comparing model-generated results with experimental data from references. The effects of critical operating parameters on the system performance have been investigated parametrically. Through an optimization, a maximum solar-to-fuel efficiency ηSTF = 25.4% has been achieved, which is 6.4% higher than a typical solar-driven high temperature co-electrolysis.
