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.

该项目旨在开发一种基于电化学水解离的零电能输入制氢系统。该项目将以比水电解和重整等商业系统更低的成本生产氢气，从而彻底改变氢气生产。它为氢提供了一条可持续的途径，大大减少了碳排放。该提案涉及开发一种基于通过直接和间接电解转化废物、酒精和生物质的强大制氢装置。该工艺使用均相或非均相催化剂作为载流子，有几个优点。催化氧化还原反应可以在溶液中发生，因此不需要贵金属阳极。电解能量要求很低；是传统电解水的20%。这与阳极的析氧反应被较低电位的间接氧化所取代有关，这导致施加电位的显著降低。该方法将测试一种新型电解槽的可行性，其中一半的电解槽产生电能，从而补充氢生成所需的低电势；使之成为零能耗的电解槽。
