Competing with gray or blue hydrogen poses an economic challenge, especially in markets with minimal subsidies or carbon pricing.

Green hydrogen production via electrolysis requires large quantities of purified or desalinated water, about 9 liters per kilogram of hydrogen. In water-stressed or arid regions, this adds operational complexity and cost, making project development less feasible.

GREEN HYDROGEN MARKET SEGMENTATION INSIGHTS

INSIGHTS BY TECHNOLOGY

The global green hydrogen market by technology is segmented into alkaline electrolysis, proton exchange membrane, and others. The alkaline electrolysis (ALK) segment accounted for the largest market share of over 61%, reflecting its crucial role in the clean energy transition. ALK systems operate using an alkaline electrolyte, typically potassium hydroxide (KOH), to split water molecules into hydrogen and oxygen. Their proven scalability makes them particularly well-suited for large-scale hydrogen production, aligning with industrial needs and grid-level energy storage applications. A key driver of demand for alkaline electrolysis is its seamless integration with renewable energy sources. As the world moves toward decarbonization, storing surplus renewable energy has become essential to ensuring energy stability. ALK systems help convert this excess energy into green hydrogen, offering a flexible and reliable storage solution to mitigate the intermittency of solar and wind power.

Moreover, the declining costs of renewable energy and ongoing technological advancements in electrolysis are strengthening the competitiveness of ALK technology. As renewable electricity becomes more affordable, the cost-efficiency of green hydrogen production improves, encouraging broader adoption across industries seeking to reduce their carbon emissions.

INSIGHTS BY SOURCE

The global green hydrogen market by source is categorized into wind energy, solar energy, and others. The wind energy segment dominates and holds the largest share in 2024. Wind energy is a key renewable source for producing green hydrogen through electrolysis, owing to its maturity, wide adoption, and alignment with global decarbonization goals. The growing push toward clean energy transition has intensified the demand for renewable hydrogen as a sustainable fuel, positioning wind power as a central contributor due to its low emissions and abundant availability. The intermittent nature of wind generation complements the flexible operation of electrolyzers, which can be ramped up or down depending on energy availability. This adaptability makes wind energy particularly suitable for green hydrogen production, especially in regions rich in wind resources such as coastal areas and open plains.

In October 2024, ABO Energy received approval under the German Federal Immission Control Act for its first hydrogen pilot project. The initiative will integrate a wind turbine with green hydrogen production and include both a refueling station and a trailer filling facility.

INSIGHTS BY END-USER

Based on the end-user, the refining segment accounts for the largest global green hydrogen market share in 2024. This industry currently accounts for approximately 40 million tonnes of hydrogen consumption annually, primarily for essential processes such as hydrocracking and desulfurization of fuels like diesel and petrol. Traditionally, this hydrogen has been derived from fossil fuels, particularly through steam methane reforming (SMR), contributing to considerable carbon emissions. Hydrogen plays a central role in the refining process, especially in the desulfurization of crude oil to meet quality standards for end products. The demand for hydrogen in this context is driven by two primary factors. First, the global demand for refined petroleum products is expected to grow, particularly in emerging economies. Second, stringent environmental regulations aimed at reducing sulfur content in fuels are intensifying hydrogen use in desulfurization processes.
