Four years have passed since Europe launched its ambitious hydrogen strategy recognising hydrogen as a key decarbonisation pillar of the economy. Not only in Europe, but well across the Atlantic, in China, India, Japan, and in the Middle East investments into clean hydrogen production are rapidly growing. In Europe, only 4 percent of the announced clean hydrogen volumes are under construction, including only 3 percent of the electrolytic ones. Under the Fit for 55 package, the European Union has designed a regulatory framework which could help the emerging clean hydrogen market.
