There is growing interest in the potential use of hydrogen in reducing emissions in hard to abate industrial sectors such as iron/steel, and ammonia production. We present results from a recent economic analysis of clean hydrogen production for decarbonizing steelmaking and ammonia synthesis via three key production routes: steam methane reforming, grid attached electrolysis, and off-grid renewable-driven electrolysis. We consider current and projected electrolyzer costs, natural gas costs, and utilize location-specific hourly wind and solar data over the course of a potential operational year, to estimate hydrogen production, delivery and storage needs. This work provides insights about when, where, and how low-carbon hydrogen production can potentially reduce CO2 emissions of steelmaking and ammonia synthesis, and at what cost.
