Building the green hydrogen market-Current state and outlook on green hydrogen demand and electrolyzer manufacturing

Over the past two years, requirements to meet climate targets have been intensified. In addition to the tightening of the climate targets and the demand for net-zero achievement by as early as 2045, there have been discussions on implementing and realizing these goals. Hydrogen has emerged as a promising climate-neutral energy carrier. Thus, over the last 1.5 years, more than 25 countries have published hydrogen roadmaps. Furthermore, various studies by different authorities have been released to support the development of a hydrogen economy. This paper examines published studies and hydrogen country roadmaps as part of a meta-analysis. Furthermore, a market analysis of electrolyzer manufacturers is conducted. The prospected demand for green hydrogen from various studies is compared to electrolyzer manufacturing capacities and selected green hydrogen projects to identify potential market ramp-up scenarios, and to evaluate if green hydrogen demand forecasts can be filled.(c) 2022 The Authors.
