The article discusses the impending cost competitiveness of green hydrogen by 2030 as a pivotal solution for decarbonizing challenging sectors like steel, aviation, and shipping. ABI Research projects a significant drop in the Levelized Cost of Hydrogen (LCOH) from the current US$6-7/kg to about US$2.5/kg by the end of the decade, further decreasing to US$1/kg by 2050. This cost reduction will be propelled by advancements in electrolyzer efficiency, declining costs of renewable energy, and the realization of economies of scale. Major players in the electrolyzer market such as ITM Power, Siemens Energy, and Plug Power, in addition to technology vendors like Danfoss and Schneider Electric, are expected to play critical roles in driving down capital and operational costs. The transition towards green hydrogen is anticipated to help industries align with their net-zero goals. ABI Research underscores the importance of accurate cost assessments to facilitate the widespread adoption of green hydrogen and to pinpoint lucrative market opportunities.
