Abstract：Hydrogen energy is an widely used, abundant, green, low-carbon energy carrier. Hydrogen is gradually becoming one of the most important energy carriers for our future green energy transformation. This paper provides a detailed introduction to the basic and applied research achievements in various fields related to hydrogen production made by the Department of Energy and Power Engineering, Tsinghua University. A pyrochrite catalyst was synthesized for hydrocarbon fuel reforming with prototype hydrogen reforming units then used to evaluate the catalyst effectiveness. An elevated temperature purification process was developed for elevated temperature hydrogen production using both a nitrogen-modified activated carbon hydrophobic adsorbent and a layered double hydroxide based adsorbent for the entire temperature range which can provide on-site H2/CO2 separation using elevated temperature pressure swing adsorption. For electrolysis using renewable energy sources, the co-electrolysis of carbon dioxide and water to produce hydrogen was realized in a solid oxide electrolytic cell with the energy consumption of the alkaline water electrolysis reduced by raising the temperature to reduce the theoretical water decomposition voltage. These results contribute to the international hydrogen fuel cell industry developing efficient hydrogen production technologies that will boost the transformation of future energy utilization systems as a crucial step towards building a low-carbon, safe and efficient modern energy system.
