The Hydrogen Production Research Division focuses on addressing the most critical challenge toward realizing a hydrogen-based society: the development of low-cost green hydrogen production technologies. This includes high‑efficiency steam and water electrolysis powered by solar energy or other renewables, as well as geological hydrogen, and photocatalytic or photoelectrochemical conversion.

A comprehensive research portfolio covers materials, components, characterization, modeling, and device fabrication, including catalysts, electrodes, and electrochemical cell systems. Innovative approaches also include catalytic technologies that utilize organic dyes to harvest a broad range of wavelengths, and investigations into naturally formed hydrogen production.
