The world needs to be able to make fertilizers for industrial agriculture after we run out of fossil fuels. We currently do this using hydrogen split from natural gas in the Haber-Bosch process. In order to decarbonize agriculture, we have no choice but to make hydrogen at a scale large enough that it becomes attractive for a number of other applications such as steel and cement manufacture, shipping, and aviation. Hydrogen is inevitable.
