The Rise of Green Hydrogen

At the heart of the hydrogen revolution lies green hydrogen—hydrogen produced through electrolysis powered by renewable energy sources such as wind, solar, and geothermal. Unlike grey hydrogen (produced from fossil fuels with significant CO₂ emissions), green hydrogen offers a carbon-free alternative that aligns with global climate goals.

Governments around the world are actively promoting green hydrogen through subsidies and policy incentives. For instance, Indonesia’s Kamojang Geothermal Power Plant began green hydrogen production in March 2024, showcasing the increasing government involvement in sustainable hydrogen initiatives.

Despite its environmental appeal, green hydrogen remains costlier than conventional hydrogen forms. However, technological advances in electrolyzers, improved storage solutions, and cheaper renewable electricity are gradually making green hydrogen economically viable.

Diverse Production Technologies Driving Market Dynamics

Hydrogen can be produced through several methods:

• Steam Methane Reforming (SMR) – Cost-effective and widely used, but carbon-intensive.
• Electrolysis – The key method for green hydrogen production.
• Thermochemical, biological, and direct solar water splitting – Emerging technologies with significant future potential.

Among these, SMR currently dominates due to its low cost and scalability. However, with R&D efforts focused on improving electrolysis and photoelectrochemical (PEC) water-splitting, the market is shifting toward cleaner methods. PEC, for instance, uses sunlight and semiconducting materials to split water molecules directly—a process with tremendous potential to limit greenhouse emissions.

In July 2024, German Fraunhofer Institutes made headlines by developing high-purity semiconductor materials for direct hydrogen production using tandem PEC modules—highlighting how scientific innovation is propelling the industry forward.

Hydrogen as a Versatile Energy Carrier

Hydrogen is a multi-functional energy carrier, widely used in:

• Fuel Cell Electric Vehicles (FCEVs) for road, rail, and maritime transport
• Industrial processes requiring high-temperature heat
• Energy storage for intermittent renewable sources
• Residential and commercial heating

Its ability to produce electricity, heat, and water without carbon emissions makes it ideal for decarbonizing hard-to-abate sectors like heavy industry and freight transport.

Asia Pacific at the Helm

Asia Pacific emerged as the largest regional market in 2023, and is projected to maintain its dominance through 2034. Countries like China, Japan, India, and South Korea are making massive investments in hydrogen infrastructure.

Notable example: In June 2024, Towngas (Hong Kong) and Veolia partnered to develop a green hydrogen project at the South East New Territories Landfill Extension (SENTX), reflecting the region’s commitment to large-scale hydrogen deployment.

Meanwhile, North America is catching up with the growth of retail hydrogen stations. By the end of 2023, the U.S. had 59 operational hydrogen stations, with 50 more in various development stages.
