The hydrogen value chain, known as the hydrogen economy, is experiencing significant growth driven by factors on both the demand and supply sides. Industries are pushing for decarbonization in hard-to-abate sectors like refining and ammonia production due to regulatory pressures like carbon taxes. Advances in hydrogen technologies are further propelling this demand. On the supply side, innovative financing and incentives, especially for green hydrogen producers, are facilitating growth. There are two primary pathways for producing low-carbon hydrogen: blue hydrogen and green hydrogen. Green hydrogen, produced through water electrolysis with renewable energy, is seen as the ultimate clean solution. Major investments and regulatory developments are shaping the green hydrogen sector, with projects like Sweden's H2 Green Steel and ACWA Power's plant in Saudi Arabia leading the way. Manufacturing capacity for water electrolyzers is increasing globally, with expansions in North America, Europe, and Asia-Pacific. The market is also seeing a rise in electrolyzer OEMs, indicating the growing interest in green hydrogen. The global green hydrogen market is projected to grow significantly, with forecasts indicating a substantial increase in installed electrolyzer capacity by 2034.
