The global energy transition is accelerating, with a specific focus on the green hydrogen industry, essential for various sectors including food, metal production, and refining. While sustainable alternatives like electrolysis systems are gaining traction, the high cost of water electrolysis remains a challenge. Analysts estimate a $1 trillion subsidy requirement by 2030 to realize all proposed projects. The Potsdam Institute suggests establishing green hydrogen quotas to stimulate demand and decrease reliance on subsidies. Unique strategies like tiered subsidies in India and large-scale projects such as SouthH2 in the EU demonstrate the increasing momentum for green hydrogen. International collaborations and initiatives in regions like the United Arab Emirates and Oman are further fueling the industry's growth. The sustainable aviation fuel market is also embracing green hydrogen to overcome challenges faced by biomass-derived fuels, paving the way for innovative solutions. In the U.S., the Regional Clean Energy Hubs program aims to diversify the hydrogen supply chain. Overall, the industry shows promise for significant growth, albeit with challenges that require global cooperation and innovative solutions.
