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.
A recent Ammonia Energy post mentioned that in December 2017 “the Japanese government . . . approved an updated hydrogen strategy which appears to give ammonia the inside track in the race against liquid hydrogen (LH2) and liquid organic hydride (LOH) energy carrier systems.” While this news is positive, the hydrogen strategy remains the essential context for economic implementation of ammonia energy technologies in Japan; ammonia’s prospects are only as bright as those of hydrogen. This is why Ammonia Energy asks from time to time, how is hydrogen faring in Japan?
Over the last few weeks, I've written extensively about sustainable ammonia synthesis projects funded by the US Department of Energy (DOE). While these projects are important, the US has no monopoly on technology development. Indeed, given the current uncertainty regarding energy policy under the Trump administration, the US may be at risk of stepping away from its assumed role as an industry leader in this area.
This article introduces seven international projects, representing research coming out of eight countries spread across four continents. These projects span the breadth of next-generation ammonia synthesis research, from nanotechnology and electrocatalysis to plasmas and ionic liquids.
