The project aims to develop a hydrogen generation system based on electrochemical water dissociation with zero electrical energy input. The project will revolutionise hydrogen production by creating hydrogen at a lower cost than commercial systems such as water electrolysis and reforming. It provides a sustainable route to hydrogen significantly reducing carbon emissions. This proposal is concerned with development of a robust hydrogen generator based on the conversion of waste, alcohols and biomass via direct and indirect electrolysis. The process uses either homogeneous or heterogeneous catalysts as charge carriers, which has several advantages. The catalytic redox reaction can occur in the solution and as a result, a noble metal anode is not needed. The electrolysis energy requirement is very low; 20% of that in conventional water electrolysis. This is related to the replacement of the oxygen evolution reaction at the anode with the indirect oxidation at a lower potential, which leads to a significant reduction in applied potential. The approach will test the feasibility of a novel electrolyser in which half the electrolyser generates electrical energy and thus supplements the low electrical potential required for the hydrogen generation; making it a zero energy electrical consuming electrolyser.
