For decades, green hydrogen has been touted as the “next big thing” in clean energy technology, with particularly promising potential applications in hard-to-abate sectors like transport, steelmaking, and shipping. However, the long-predicted green hydrogen renaissance has never come to fruition due to several factors, including the prohibitively high cost of production and the energy losses and inefficiencies associated with using green hydrogen rather than clean energy directly. Hydrogen can be combusted at high temperatures…
