In a recent study analyzing 180,000 patents from 2013 to 2022 across five hydrogen-related fields, China has surpassed Japan to become the global leader in hydrogen-related patent competitiveness. China ranked first in four out of five fields, showing a remarkable increase in filings since President Xi Jinping's 2020 pledge to peak carbon emissions by 2030. Chinese companies have intensified their efforts in the manufacturing sector, particularly in the production of electrolyzers, now constituting 60% of global manufacturing. On the other hand, Japan's market remains limited, with few companies like Asahi Kasei and Toshiba contributing to the filings. While Japan and Europe concentrate on consumer applications of hydrogen cells, China has strategically targeted industrial sectors with high hydrogen demands like steel and chemical production. Despite Japan's planned subsidies for hydrogen use and collaborations with key partners like the U.S. and South Korea, China's current dominant position in hydrogen patents, fueled by substantial corporate investments, seems poised to endure.
