Electrochemical Promotion of Ammonia Synthesis with Proton-Conducting Ceramic Fuel Cells -Function of Electrode Interface for Ammonia Formation Reaction-

The advance of efficient and economical energy carrier technology is an important challenge in terms of storage and transport of hydrogen fuels produced from renewable energy. Ammonia is a promising candidate of energy carrier because of high energy density and easy liquefaction as well as a carbon-free fuel.1 Electrochemical synthesis has a potential for an efficient ammonia production in comparison with the industrial Haber–Bosch process. In our previous study, we observed the improvement of electrochemical synthesis of ammonia using iron-based electrode catalyst such as K-Al-Fe-BaCe0.9Y0.1O3 (BCY).2 In the study, basically, H2 decomposition occurs to form protons in the anode side,…

Advances Reported for MCH and LH2

Two recent announcements show that the race is still very much on among the energy carriers that until recently were a focus of the Japanese Cabinet Office’s Cross-Ministerial Strategic Innovation Promotion Program (SIP).  During its five-year career, the SIP Energy Carriers initiative promoted the development of liquid hydrogen (LH2), liquid organic hydrides (LOH), and ammonia as technologies that could animate a hydrogen supply chain spanning continents and oceans.  The announcements regarding LH2 and methyl cyclohexane (MCH -- the main Energy Carriers focus in the LOH area) show that the conclusion of the Energy Carriers work at the end March does not mean the conclusion of work on these two rivals to ammonia energy.
