The rise of green hydrogen is touted as a game-changer in the evolving energy transition scene as the global push for decarbonisation gains momentum. Forecasts predict a substantial growth trajectory for the green hydrogen market, with expectations to surpass $515.66 billion by 2035, fueled by an impressive CAGR of 61% from 2023 to 2035. Particularly crucial for 'hard to abate' industries, where conventional decarbonisation methods fall short, green hydrogen emerges as a promising solution for challenging sectors. Its integration into legislative frameworks like the EU's Renewable Energy Directive II and III in Europe and the Inflation Reduction Act in the US signifies its pivotal role in shaping the future of sustainable fuels, notably in the aviation sector. Noteworthy investments are already in progress in Europe and the US aimed at advancing green hydrogen technologies, showcasing a dedicated effort to propel the growth and influence of this sector in the energy domain.
