A recent market research study by Information Trends predicts a significant surge in electrolyzer production capacity worldwide, exceeding 14 terawatts over the next 15 years. The demand for green hydrogen as a sustainable energy source is driving this growth, with a focus on generating hydrogen from renewable energy sources. Asia-Pacific, spearheaded by China, leads in the deployment of electrolyzers, followed by Europe and North America. The study highlights four key electrolyzer technologies, with PEM electrolyzers projected to dominate the market by 2039. Additionally, substantial growth is anticipated in Solid Oxide Electrolyzer Cell (SOEC) and Anion Exchange Membrane (AEM) electrolyzers, with SOEC showing great potential for cost-effective hydrogen production. Notably, China's LONGi Hydrogen currently leads the market share among electrolyzer manufacturers, with a significant presence of manufacturers in Europe and the U.S. The study refutes claims of an overbuild of electrolyzer capacity, emphasizing the crucial role of electrolyzers in meeting the escalating demand for green hydrogen production. The forecast underscores the pivotal shift towards sustainable energy solutions and the vital role electrolyzers play in the global energy transition.
