The global green hydrogen market is on the rise, with a projected CAGR of 20.9% during the period 2024-2031. Green hydrogen, produced through electrolysis using renewable energy sources, is gaining traction as a sustainable and environmentally friendly alternative to traditional hydrogen production methods. The market is expanding rapidly as governments and industries worldwide aim to reduce carbon emissions and achieve sustainability targets. One of the key drivers of green hydrogen adoption is its use in the transportation industry. By powering vehicles like fuel cell electric cars and buses, green hydrogen helps reduce air pollution and lower carbon dioxide emissions. The European Union, for example, plans to establish thousands of hydrogen fueling stations by 2030 to support fuel cell vehicles. While the growth of green hydrogen presents promising opportunities, challenges remain in manufacturing, transportation, and storage. Companies like Enapter are working to reduce production costs, making green hydrogen more competitive. However, uncertainties in supply chain design and network infrastructure pose challenges for decision-makers. The competitive landscape of the green hydrogen market includes key players like Siemens Energy, Linde AG, and Cummins Inc., among others. These companies are driving innovation and technological advancements in green hydrogen production. Regionally, the U.S. is making strides in green hydrogen production, with plans to transition from grey hydrogen to blue and green hydrogen production methods. By 2025, the U.S. could have its largest green hydrogen hub, further contributing to the global shift towards sustainable energy solutions.
