The global green hydrogen market is poised to grow by $46.2 billion between 2024 and 2028, with a staggering compound annual growth rate (CAGR) of 66.83%.
This explosive growth is fueled by the urgent need to decarbonize industries, the falling costs of renewable energy, and the increasing adoption of hydrogen as a clean energy solution. Yet, despite its promise, the market faces significant challenges, including high production costs, infrastructure gaps, and competition from alternative technologies.
Green hydrogen, produced through electrolysis powered by renewable energy sources like wind and solar, represents a paradigm shift in the global energy landscape. Unlike gray hydrogen, which is derived from fossil fuels and emits significant CO₂, green hydrogen offers a carbon-free alternative. According to the International Energy Agency (IEA), hydrogen demand reached 94 million metric tons in 2022, with green hydrogen accounting for less than 1% of total production. However, this figure is expected to rise dramatically as governments and industries push for net-zero emissions.
The stakes are high. The global energy sector accounts for nearly 75% of greenhouse gas emissions, and hydrogen could abate up to 80 gigatons of cumulative CO₂ emissions by 2050 if deployed at scale. This potential has spurred investments exceeding $300 billion in hydrogen projects worldwide, with green hydrogen at the forefront.
The primary driver of green hydrogen adoption is the global push for decarbonization. Industries such as chemicals, refining, and steel production, which are traditionally hard to abate, are increasingly turning to green hydrogen as a viable solution. For instance, the chemical sector, which accounted for $309.4 million in green hydrogen demand in 2018, is projected to grow significantly as companies seek to produce low-carbon ammonia and methanol.
Government policies are also playing a critical role. The European Union’s Hydrogen Strategy aims to install 40 gigawatts (GW) of electrolyzer capacity by 2030, while the U.S. Inflation Reduction Act offers tax credits of up to $3 per kilogram of green hydrogen produced. In Asia-Pacific, countries like China and India are investing heavily in hydrogen infrastructure to meet their climate goals and reduce reliance on imported fossil fuels.
Asia-Pacific is the largest and fastest-growing market for green hydrogen, accounting for 57% of global demand in 2023. China and India are driving this growth, with both countries investing heavily in renewable energy and hydrogen infrastructure. China alone is expected to account for 40% of global electrolyzer capacity by 2030, driven by its ambitious climate targets and industrial demand.
Europe and North America are also key players, with the EU and U.S. leading in policy support and technological innovation. In Europe, projects like the HyDeal Ambition initiative aim to produce green hydrogen at €1.5 per kilogram by 2030, while the U.S. is leveraging its abundant renewable resources to become a major exporter of green hydrogen.
The green hydrogen market is highly fragmented, with over 20 major players competing for market share. Companies like Air Liquide, Linde, and Siemens Energy are leading the charge, investing in large-scale electrolyzer projects and forming strategic partnerships. For example, Air Liquide and Siemens Energy are collaborating on a 200-megawatt (MW) electrolyzer project in Germany, set to produce 30,000 metric tons of green hydrogen annually.
Startups and niche players are also making waves. Sgh2 Energy, for instance, is pioneering a novel approach to hydrogen production by gasifying waste materials, offering a cost-effective and sustainable alternative to traditional electrolysis.
Alkaline vs. PEM Electrolyzers
The choice of electrolyzer technology is a critical factor in green hydrogen production. Alkaline electrolyzers, which dominate the market due to their lower cost and longer lifespan, are expected to account for 60% of installed capacity by 2028. However, proton exchange membrane (PEM) electrolyzers are gaining traction due to their higher efficiency and ability to operate at variable loads, making them ideal for integration with intermittent renewable energy sources.
Innovation in electrolyzer design and materials is driving down costs and improving performance. For example, Nel ASA has developed a PEM electrolyzer with a stack cost of $300 per kilowatt (kW), a 50% reduction from 2020 levels. Similarly, advancements in catalyst materials, such as iridium-free anodes, are reducing reliance on expensive rare earth metals.
The green hydrogen market is at a critical juncture. While the potential for growth is immense, realizing this potential will require significant investment in infrastructure, technological innovation, and policy support. According to BloombergNEF, achieving cost parity with gray hydrogen by 2030 will require electrolyzer costs to fall below 500 per kW and renewable energy prices to drop to 20 per megawatt-hour (MWh).
As the market matures, collaboration between governments, industries, and research institutions will be essential to overcome challenges and unlock the full potential of green hydrogen. With the right strategies and investments, green hydrogen could play a pivotal role in the global transition to a sustainable, low-carbon economy.
