Kilowatt-scale solar hydrogen production system using a | ResearchBunny

Abstract

This paper presents the successful scaling of a thermally integrated photoelectrochemical device using concentrated solar irradiation to a kW-scale pilot plant capable of co-generating hydrogen and heat. A solar-to-hydrogen device-level efficiency of over 20% at a hydrogen production rate of >2.0 kW is achieved. A validated model-based optimization identifies key energy losses and suggests strategies for improving system efficiency. The paper also addresses technological challenges, control strategies, and the future outlook of this technology.
