As the 2030 Paris Agreement targets approach, competition in green hydrogen among the EU, China and the US has reached a pivotal phase. Norway's "OceanH2", the world's largest offshore hydrogen platform launched this week, utilizes North Sea wind power to produce 300,000 tons of carbon-free hydrogen annually – enough to replace 500,000 tons of fossil fuels.

Tech Breakthrough
Siemens Energy's new proton-exchange membrane electrolyzer achieves 85% efficiency, a 40% improvement since 2020. Meanwhile, China's "Hydrogen Corridor" transports green hydrogen 4,000km from western renewables bases to eastern industrial zones, projected to meet 10% of national energy demand by 2030.

Controversies
Although IEA forecasts hydrogen will supply 18% of global energy by 2050, experts warn current $120bn annual investment meets just one-third of requirements. Developing nations are demanding equitable technology sharing to prevent a green divide.
