Electrolyzers Global Market Report 2025

Electrolyzers are devices designed to utilize electricity for the purpose of separating hydrogen and oxygen molecules within water through a chemical process known as electrolysis. This process effectively generates hydrogen as a byproduct. Electrolyzers are employed in processes that involve the separation of water into its constituent elements, hydrogen and oxygen.

The primary types of electrolyzers are alkaline electrolyzers, PEM (Proton Exchange Membrane) electrolyzers, and solid oxide electrolyzers. Alkaline electrolyzers typically operate within a temperature range of 80-160 °C. Electrolyzer capacities are categorized into less than 500 kW, 500 kW to 2 MW, and above 2 MW. These electrolyzers find applications in various sectors, including power plants, steel plants, electronics and photovoltaics, industrial gases, energy storage, fueling for Fuel Cell Electric Vehicles (FCEV), power-to-gas processes, and other related applications.

The electrolyzers market size has grown strongly in recent years. It will grow from $0.35 billion in 2024 to $0.38 billion in 2025 at a compound annual growth rate (CAGR) of 9.1%. The growth in the historic period can be attributed to increasing demand for hydrogen as a clean energy carrier, government incentives and subsidies, environmental awareness, expansion of renewable energy sources, early adopters and pilot projects in various industries.

The electrolyzers market size is expected to see strong growth in the next few years. It will grow to $0.54 billion in 2029 at a compound annual growth rate (CAGR) of 8.9%. The growth in the forecast period can be attributed to emerging applications inThe aviation and maritime sectors, expansion of global hydrogen infrastructure, integration of electrolyzers with renewable energy projects, increasing carbon emissions reduction regulations, increasing growth inThe use of power-to-gas systems. Major trends in the forecast period include green hydrogen production, decentralized hydrogen production, technology advancements, green ammonia production, hydrogen in transportation.

The increasing demand for fuel cell-based vehicles is significantly boosting the growth of the electrolyzers market. A fuel cell-based vehicle is an electrically driven automobile that utilizes hydrogen as an energy source through a fuel cell that generates electricity. Electrolyzers facilitate the operation of these fuel cell vehicles by producing hydrogen for use as fuel. For example, in September 2024, the California Fuel Cell Partnership reported that the number of fuel cell vehicles sold and leased in the United States reached 18,355 in 2024. Consequently, the rising demand for fuel cell-based vehicles is propelling the expansion of the electrolyzers market.

Anticipated growth in the production of green electricity is poised to be a pivotal factor driving the electrolyzer market in the foreseeable future. Green electricity, derived from renewable and environmentally sustainable sources, has gained prominence due to its lower environmental impact and reduced greenhouse gas emissions compared to conventional fossil fuel-based power generation. Electrolyzers play a crucial role in facilitating the storage and utilization of surplus electricity generated by renewable sources, aligning with the global shift towards more eco-friendly and renewable energy solutions. In September 2022, renewable energy accounted for 24% of utility-scale electricity generation in the United States, marking a significant increase from the previous year's 21%. This surge in green electricity production is a key driver propelling the electrolyzer market forward.

A noteworthy trend influencing the electrolyzers market is the ongoing technological advancements within the industry. These advancements represent the evolution of knowledge and capabilities in technology. For instance, in November 2022, Bloom Energy Corporation, a publicly traded U.S.-based firm specializing in solid oxide fuel cells, introduced a high-volume commercial electrolyzer line at its Newark facility. This expansion doubled the company's electrolyzer production capacity to two gigatons. The innovative Bloom Electrolyzer, built on a proven solid oxide technology platform used for energy generation, stands out as an exceptionally energy-efficient solution for clean hydrogen production. This development not only streamlines the manufacturing process for larger-volume electrolyzer production but also positions Bloom Energy Corporation to better meet the growing demands of the market.

Key players in the electrolyzer market are strategically focusing on product innovations, such as the development of solid oxide electrolyzers, to better cater to the demands of their existing customer base. A solid oxide electrolyzer (SOE) is an electrochemical device that converts electrical power into chemical energy using solid oxide materials. Functioning similarly to a fuel cell in reverse, it employs electricity to drive a chemical process, generating hydrogen gas (H2) and oxygen gas (O2) from water (H2O), rather than producing power from a chemical reaction. In April 2022, Bloom Energy Corporation, a U.S.-based electrolyzer manufacturer, announced the international deployment of its high-temperature solid oxide electrolyzer. Following the commercial success of the Bloom Electrolyzer in 2021, the installation in Gumi, South Korea, marked a significant step in Bloom Energy's pursuit of a hydrogen-fueled economy. The high-temperature electrolyzer offers more efficient on-site hydrogen production compared to lower-temperature PEM and alkaline electrolyzers. Operating at high temperatures, it requires less energy to break water molecules and create hydrogen, enhancing the economics of hydrogen generation and promoting adoption.

Rolls-Royce Limited, a UK-based luxury automobile and aero-engine manufacturing company, made a strategic move in June 2022 by acquiring a 54% majority stake in Hoeller Electrolyzer GmbH, a Germany-based electrolyzer manufacturing company. The acquisition, conducted for an undisclosed amount, positions Rolls-Royce Limited to enter the hydrogen manufacturing market. This strategic investment enables Rolls-Royce Limited to offer comprehensive hydrogen solutions, contributing significantly to climate protection. Clients will benefit from Rolls-Royce Limited's solutions, allowing them to store renewable energy in the form of hydrogen for various applications, including on-demand usage, further processing, or resale. This acquisition aligns with Rolls-Royce Limited's commitment to expanding its presence in the evolving hydrogen market.
