Green Hydrogen Market Report 2025

The green hydrogen market size has grown exponentially in recent years. It will grow from $2.46 billion in 2024 to $3.83 billion in 2025 at a compound annual growth rate (CAGR) of 55.4%. The growth in the historic period can be attributed to emerging markets growth, low interest rate environment, high environment impact of conventional power generation sources and increased demand from the chemical industry.

The green hydrogen market size is expected to see exponential growth in the next few years. It will grow to $16.65 billion in 2029 at a compound annual growth rate (CAGR) of 44.4%. The growth in the forecast period can be attributed to faster economic growth, government initiatives, global population growth and urbanization, rising investment for renewable power generation, focus on reducing foreign oil dependence, growing demand from end-use industries and global collaborations for environmental protection. Major trends in the forecast period include implementing AI technology to increase operational efficiency, offering IoT-related advisory solutions to increase operational efficiency, implementing digital twin technology solutions to reduce the risks, implementing smart meters to accurately measure the flow rate and concentration of hydrogen gas, increasing investments to capitalize on the growing demand and focusing on growth strategies and formulate a collaborative approach to grow market share.

The anticipated growth of the green hydrogen market in the forecast period is driven by increasing environmental concerns. Green hydrogen, a hydrogen-based fuel, is produced through water electrolysis using electricity from low-carbon sources, contributing to carbon emissions reduction and environmental care. Notably, the International Energy Agency (IEA) targets achieving global energy-related carbon dioxide emissions net zero by 2050. Fossil fuels, responsible for 80% of worldwide energy, significantly contribute to poor air quality, with IEA estimating around 1.77 million premature deaths due to indoor air pollution and 4.97 million due to outdoor air pollution by 2050. The World Health Organization reports that 4.2 to 7 million people die annually from air pollution, emphasizing the role of green hydrogen in addressing these concerns.

The global population's growth is expected to fuel the demand for utilities and transportation. The UN projects a world population of 9.8 billion by 2050, necessitating increased services such as power distribution, air conditioning, and transportation, further driving the green hydrogen market. Urbanization is a key factor, with the United Nations estimating that 68% of the world's population will reside in urban areas by 2050. The International Energy Agency predicts a 25% to 30% increase in global energy demand by 2040, particularly in developing economies experiencing rapid urbanization and population growth, presenting opportunities for the green hydrogen market.

Major companies in the green hydrogen market are increasingly focused on establishing Green Hydrogen Electrolyzer Gigafactories to support global efforts in achieving carbon neutrality and sustainable energy systems. A Green Hydrogen Electrolyzer Gigafactory is a large-scale manufacturing facility dedicated to producing electrolyzers, which are essential for generating green hydrogen through electrolysis. For instance, in October 2023, Ohmium International announced the launch of India’s first Green Hydrogen Electrolyzer Gigafactory. This facility will initially produce 500 MW of Proton Exchange Membrane (PEM) hydrogen electrolyzers per year, with plans to scale up production to 2 GW. The gigafactory aims to reduce India's dependence on imported electrolyzers and facilitate the production of green hydrogen, a zero-carbon fuel applicable across various industries, including fertilizer and steel production.

Companies in the green hydrogen market are increasingly pursuing significant collaborations to enhance their market reach and improve their product offerings. Partnerships between the industry and government play a crucial role in assessing the economic viability and environmental benefits of sustainable practices. Over the past decade, the market has seen numerous collaborations among companies. For instance, in January 2022, the Indian Ministry of New and Renewable Energy partnered with the International Renewable Energy Agency (IRENA) to collaborate with industry stakeholders in accelerating green hydrogen production and energy transformation. Additionally, in January 2022, Hero Future Energies (HFE), a developer of solar, wind, and hybrid/BESS projects, teamed up with Ohmium International. This partnership aims to establish and develop 1,000 MW of green hydrogen production facilities in India, the UK, and Europe.

In November 2024, ANDRITZ AG, a U.S.-based international technology company, acquired a 13.8% stake in HydrogenPro AS for an undisclosed amount. This acquisition aims to enhance ANDRITZ AG's capabilities in the green hydrogen sector by integrating HydrogenPro AS's advanced electrolyzer technology into its portfolio. This move will strengthen ANDRITZ AG's position as a leading provider of engineering, procurement, and construction (EPC) services for green hydrogen production, addressing the growing demand for renewable energy solutions. HydrogenPro AS is a Norway-based company specializing in green hydrogen.

Green hydrogen gas is generated by splitting water into hydrogen and oxygen through an electrolyzer powered by renewable energy sources. This environmentally friendly hydrogen variant is capable of being stored and converted back to energy or heat as needed.

The primary technologies associated with green hydrogen include alkaline electrolyzers, proton exchange membrane electrolyzers, and solid oxide electrolyzers. Alkaline electrolyzers operate by transporting hydroxide ions from the cathode to the anode through the electrolyte, resulting in hydrogen production on the cathode side. This technology finds applications in power generation, transportation, and various other sectors such as petrochemicals, food and beverages, medical, chemical, glass, and more.
