Feasibility Study and Assessment of a Solar-Powered Hydrogen Electrolyser-Fuel Cell Integrated System for Building Electrification [dataset] Open Access

Despite their potential to utilise renewable energy sources like solar power, green hydrogen generation technologies are still under development. This study demonstrates the feasibility of a solar-powered hydrogen electrolyser-fuel cell integrated energy system to supply electricity to an office building in London. A techno-economic-environmental integrated assessment model is presented for comprehensive system evaluation, emphasising building applications. The system can meet approximately 72% of the office building's annual energy demand, assuming unconstrained hydrogen storage with no round-trip storage losses; under a realistic storage round-trip efficiency of 85-95%, this figure reduces to approximately 61-68%. The water generated by the fuel cell can fully meet the consumption of the electrolyser during hydrogen production, demonstrating closed-loop water self-sufficiency. The overall energy conversion efficiency is close to 80%, reflecting the round-trip conversion efficiency of the PV-to-electrolyser-to-fuel-cell pathway and excluding auxiliary loads such as compression and pumping. The levelised cost of energy (LCOE) of the system is estimated to be 4.7654 £/kWh. The GHG emissions of the electrolyser and the PEMFC are 4.615 kgCO₂ eq/MJ and 0.384 gCO₂ eq/MJ, respectively. This study is positioned as a technical feasibility demonstration; while the current LCOE exceeds grid parity, projected reductions in PEM electrolyser and fuel cell capital costs are expected to substantially improve the economic case over the coming decade.
