The article discusses the projected dominance of the US, Europe, and China in global supply of low-carbon hydrogen by 2030, driven by regulatory support and growth targets. By the end of the decade, these three markets are expected to contribute 80% of the world's clean hydrogen output, with an estimated 30-fold increase in annual supply. The US is forecasted to lead with 37% of production, followed by Europe and China. The growing demand for hydrogen, including green and blue varieties, is anticipated to quadruple by 2050, particularly in industries like iron and steel, aviation, and shipping. This surge aligns with net zero emissions targets, with 95 gigawatts of electrolyzers set to be operational by 2030, mainly in Asia Pacific. Despite challenges in monitoring China's hydrogen projects, the report highlights the significant progress and potential for clean hydrogen production on a global scale.
