For many, coal has become a hydrocarbon non grata in recent years, mostly due to the considerable amount of carbon dioxide (CO2) generated when it is burned to produce electric power or heat. But what if, instead of combusting coal on its own, coal plants were co-fired by a combination of environmentally friendly versions of ammonia and the volumes of CO2 generated were way less? And what if, through the 2030s and ’40s, the ratio of fuels used in these coal-and-ammonia-fired power plants shifted away from coal and toward ammonia, and by mid-century the plants were fueled only by “green” or “blue” ammonia, which generates little or no CO2? It may sound too good to be true — heck, it may well turn out to be! But there is a lot of interest in the idea, especially in Japan, where coal still retains a big share of the power generation mix. In today’s RBN blog, we continue to look at the prospects for environmentally friendly hydrogen (H2) — and ammonia, an H2 carrier — in the power generation sector.
