Only 7% of Global Green Hydrogen Capacity Was Finished on Schedule

Green hydrogen, as a clean energy solution for hard-to-abate sectors like steelmaking, shipping, and transportation, has faced significant challenges in meeting expectations and delivering on schedule. Despite the war in Iran sparking new interest, economic headwinds, such as the high cost of hydrogen compared to gasoline, have hindered progress.

In California, the state's largest economy, the ambitious goal of hydrogen transportation has been stymied by rising costs and a dwindling number of hydrogen vehicles and fueling stations. With only two-thirds of the functional stations and a decrease in registered hydrogen cars, investors are wary of committing to this technology without knowing if the necessary infrastructure will exist.

Furthermore, the majority of hydrogen produced globally is gray, derived from fossil fuels, making the environmental benefits of green hydrogen questionable. The disparity between planned and executed green hydrogen projects, as highlighted in a study published in Nature Energy, reveals a significant gap in implementation, with only 7% of global capacity announcements completed on time in 2023.

However, this does not mean that green hydrogen is entirely without potential. The Nature Reviews paper suggests that hydrogen can still play a role in reducing greenhouse gas emissions in industries, for energy storage, and in long-haul transport. The key is to reevaluate the application of green hydrogen, focusing on areas where it can yield the greatest cost and sustainability benefits compared to alternative energy sources.

In the short term, renewable electricity could displace fossil fuels more efficiently than green hydrogen in power generation, heating, or transport. In the long term, hydrogen may serve to integrate excess renewable generation into power systems. As global fossil fuel markets experience volatility, there is a renewed interest in hydrogen, with major economies like China, the United States, and the European Union cautiously revisiting their energy strategies.

While hydrogen is no longer considered a silver bullet solution, it could be a crucial component of a more diverse and resilient global energy landscape.
