Installed capacity has grown steadily, with manufacturing capacity increasing over 25%, and projected deployments expected to reach 3 GW by the end of 2023, more than doubling 2022 levels. Traditionally used in the chlor-alkaline industry, electrolyzers are now increasingly applied for hydrogen generation. Annual capacity additions peaked in 2021 at 200 MW but slowed to 130 MW in 2022. Large-scale projects, especially in China, indicate a trend toward hundreds-of-megawatts installations, crucial for industrial decarbonization.
Market Dynamics
Electrolysis capacity dedicated to hydrogen production has experienced steady growth in recent years. However, the expansion slowed in 2022, with approximately 130 MW of new capacity becoming operational, representing a 45% decline compared to the previous year. Despite this slowdown, global electrolyzer manufacturing capacity expanded by over 25% since 2021, reaching nearly 11 GW per year in 2022. If all currently planned projects are successfully implemented, the installed electrolyzer capacity could reach 170–365 GW by 2030. Nevertheless, electrolysis deployment is still at an early stage and requires significant acceleration to align with the Net Zero Emissions by 2050 (NZE) scenario, which targets more than 550 GW of installed electrolysis capacity by 2030.
Supportive government policies, including subsidies and financial incentives, are contributing positively to the growth of the electrolyzer market. However, limited availability of electrolyzers and delays in obtaining approvals from national and local regulatory authorities pose challenges to market expansion.
