The global green hydrogen market is experiencing significant growth, with a projection to reach US$ 71.31 billion by 2031 at a staggering CAGR of 37.8% from 2025 to 2031. This growth is primarily attributed to the increasing investment in renewable energy globally. Countries worldwide, such as Australia, the European Union, and India, are actively investing in green hydrogen infrastructure to meet the rising energy and transportation demands. Australia, for instance, aims to become a leading hydrogen exporter by 2030, while India has set ambitious targets to produce 5 million metric tons of green hydrogen annually by 2030 through the National Green Hydrogen Mission. The demand for Fuel Cell Electric Vehicles (FCEVs) is on the rise as countries seek cleaner transportation alternatives. This demand has led to strategic alliances and collaborations in the market, such as the agreement between Reblko and Toyota for the supply of hydrogen fuel cell modules. Additionally, the deployment of hydrogen-powered trains in Germany showcases the potential for zero-emission rail transport using green hydrogen. Large-scale green hydrogen projects are also gaining traction, attracting substantial investments from both public and private sectors. Projects like the one in Queensland, Australia, backed by companies from Japan, Singapore, and Australia, highlight the growing interest in establishing specialized infrastructure for green hydrogen production, storage, and distribution. The geographical insights reveal North America leading the market in 2024, with Asia Pacific projected to register the highest CAGR during the forecast period. Overall, the global green hydrogen market is poised for continued growth, driven by the transition towards sustainable energy sources and low-carbon transportation.
