Hydrogen Generators Market Report 2025

The hydrogen generators market size has grown steadily in recent years. It will grow from $1.2 billion in 2024 to $1.24 billion in 2025 at a compound annual growth rate (CAGR) of 3%. The growth in the historic period can be attributed to industrial hydrogen demand, energy sector applications, government initiatives and subsidies, research and development, hydrogen as a green energy carrier.

The hydrogen generators market size is expected to see steady growth in the next few years. It will grow to $1.45 billion in 2029 at a compound annual growth rate (CAGR) of 4%. The growth in the forecast period can be attributed to rise in green hydrogen projects, electrification of industries, government policies and carbon reduction targets, expansion of hydrogen fuel cell vehicles, global collaboration on hydrogen economy, integration with renewable energy sources. Major trends in the forecast period include technological innovations in electrolysis, advancements in electrolysis technologies, advancements in electrolysis technologies, integration of artificial intelligence (AI), hydrogen as an energy storage medium.

Government regulations aimed at reducing greenhouse gas emissions are anticipated to drive the growth of the hydrogen generators market in the future. Global greenhouse gas emissions are rising, primarily due to the consumption of fossil fuels and industrialization. Major companies are developing hydrogen generators because they produce hydrogen through electrolysis, resulting in zero greenhouse gas emissions. For instance, in March 2024, the Environmental Protection Agency (EPA), a U.S.-based government agency, announced a final rule titled Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles. This rule introduces stricter standards to reduce harmful air pollutant emissions from these vehicles starting with the 2027 model year. It builds upon previous federal greenhouse gas emissions standards for passenger cars and light trucks covering model years 2023 through 2026. Therefore, as government and environmental organizations strengthen regulations to control greenhouse gas emissions, the hydrogen generators market is poised for growth.

The hydrogen generators market is expected to experience growth due to the rising focus on renewable energy production. Renewable energy production involves generating energy from naturally replenished sources with minimal environmental impact. Hydrogen generators play a crucial role in this context by converting excess renewable energy into hydrogen through electrolysis, facilitating clean fuel production or storing it for later use. In January 2023, the Energy Information Administration projected that 16% of total energy generation in 2023 would come from renewable sources, compared to 14% in 2022. Hence, the increasing emphasis on integrating renewable energy is propelling the growth of the hydrogen generators market.

Major companies are focusing on innovation to enhance profitability. A notable development is the introduction of emission-free generators by Hitachi Energy Ltd., a Switzerland-based sustainable energy system provider. In November 2023, the company launched HyFlex, a versatile unit designed for temporary or permanent setups, capable of providing power where grid connections are challenging and diesel generators are not viable. HyFlex is entirely emission-free, generating AC power, usable heat, and water. This innovation caters to various industries, including construction sites in remote areas, noise and pollution-sensitive environments, remote venues, data centers, and hospitals.

Key players in the hydrogen generator market are concentrating on forming partnerships to enhance their market profitability. Partnerships involve collaborative agreements between various entities, such as companies, organizations, or research institutions, to collectively advance hydrogen generator technologies. For instance, in September 2023, UK-based hydrogen solution provider CMB.TECH collaborated with Sweden-based marine and industrial engine manufacturer Volvo Penta to introduce a 250 kVA hydrogen dual-fuel generator. This hybrid generator utilizes hydrogen dual-fuel technology, allowing it to run on full diesel or in a dual-fuel setup, where hydrogen can substitute for up to 80% of diesel consumption. This innovation significantly reduces CO2 emissions, making it suitable for harbor activities and decentralized electricity production, serving as a transitional measure towards emission-free energy generation.

In October 2022, John F Hunt Power, a UK-based company specializing in power solutions, acquired the world's first hydrogen flybrid generator from Bruno Generators Group for an undisclosed amount. This acquisition emphasizes John F Hunt's commitment to achieving zero emissions and reinforces its investment in utilizing hydrogen in the power industry. Bruno Generators Group, an Italy-based company, is a specialist in designing and manufacturing power generation systems, including hydrogen generators.

Hydrogen generators produce hydrogen from water through electrolysis, employing a proton exchange membrane (PEM) for high-quality hydrogen gas production. These generators can either be hydrogen-powered or hydrogen-producing machines.

The primary classifications of hydrogen generators are onsite and portable. Onsite hydrogen generators allow for easy installation and quick start-up with unattended operation. These generators operate through different processes, including steam reforming and electrolysis, and serve various capacities, such as less than 300 W, 300 W to 1 KW, and more than 1 KW. They find applications in chemical processing, fuel cells, petroleum recovery, refining, and other industries.
