Green Hydrogen Market Global Report 2026

The green hydrogen market size has grown rapidly in recent years. It will grow from $3.81 billion in 2025 to $4.55 billion in 2026 at a compound annual growth rate (CAGR) of 19.3%. The growth during the historic period can be attributed to expanding renewable energy capacity, rising demand for clean fuel alternatives, government incentives for green hydrogen projects, technological improvements in electrolyzers, and increasing focus on decarbonization across industrial sectors.

The green hydrogen market size is expected to see rapid growth in the next few years. It will grow to $8.94 billion in 2030 at a compound annual growth rate (CAGR) of 18.4%. The growth during the forecast period can be attributed to the expansion of hydrogen-based transportation solutions, increasing adoption in power generation applications, investments in large-scale green hydrogen infrastructure, development of high-efficiency electrolyzers, and the emergence of international green hydrogen trade and partnerships. Key trends during the forecast period include expanded deployment of electrolyzers for renewable hydrogen production, integration of AI for hydrogen production optimization, adoption of smart monitoring and control systems for electrolyzers, implementation of predictive maintenance solutions for hydrogen plants, and development of data-driven hydrogen energy management solutions.

The increasing environmental concerns are expected to propel the growth of the green hydrogen market going forward. Environmental concerns refer to issues and challenges associated with the natural environment, including pollution, climate change, resource depletion, and ecosystem degradation, which require attention and action to protect and preserve the planet. The increase in environmental concerns is primarily driven by rising pollution levels, which negatively affect air, water, and soil quality, threaten ecosystems, and create risks to human health. Green hydrogen addresses environmental concerns by providing a clean and renewable energy source that generates zero carbon emissions, helping reduce air pollution and mitigate climate change. For instance, in May 2025, according to the United States Environmental Protection Agency, a US-based government agency, approximately 66 million tons of pollutants were emitted into the atmosphere in the United States in 2023. Therefore, increasing environmental concerns are driving the growth of the green hydrogen market.

Major companies operating in the green hydrogen market are focusing on establishing Green Hydrogen Electrolyzer Gigafactories to support global efforts toward carbon neutrality and sustainable energy systems. A Green Hydrogen Electrolyzer Gigafactory is a large-scale manufacturing facility dedicated to producing electrolyzers, which are essential devices for generating green hydrogen through electrolysis. For instance, in October 2023, Ohmium International Inc., a US-based green hydrogen technology company, launched India’s first Green Hydrogen Electrolyzer Gigafactory. The gigafactory is initially expected to produce 500 MW of Proton Exchange Membrane (PEM) hydrogen electrolyzers annually, with plans to increase capacity to 2 GW. The facility is intended to reduce India’s dependence on imported electrolyzers and facilitate the production of green hydrogen, a zero-carbon fuel applicable across industries such as fertilizer and steel production. Ohmium’s initiative supports India’s clean energy objectives and positions the country as a potential global hub for green hydrogen.

In November 2024, ANDRITZ AG, a US-based provider of hydropower plant electromechanical equipment and services, acquired HydrogenPro AS for an undisclosed amount. Through this acquisition, ANDRITZ AG aims to strengthen its capabilities in the green hydrogen sector by incorporating HydrogenPro AS’s advanced electrolyzer technology into its portfolio. The acquisition is expected to reinforce its position as a leading engineering, procurement, and construction (EPC) services provider for green hydrogen production while addressing the growing demand for renewable energy solutions. HydrogenPro AS is a Norway-based company offering green hydrogen solutions. HydrogenPro AS is a US-based company that offers green hydrogen.
