Updating the literature: Ammonia consumes 43% of global hydrogen

For years, many people — myself included — have been saying that ammonia consumes 55% of the hydrogen produced around the world. Although there are many authoritative sources for this figure, I knew that it was likely out of date. Until now, I had overlooked the International Energy Agency (IEA) 2019 report, The Future of Hydrogen, which provides up-to-date (and publicly downloadable) data for global hydrogen demand since 1975. According to the IEA, ammonia represented almost 43% of global hydrogen demand in 2018; refining represented almost 52%, and "other" demands accounted for 6%.
