Denmark inaugurated one of Europe’s few low-carbon hydrogen plants recently, a sector touted as a key to cleaner energy but plagued with challenges.
using eight electrolysers powered by solar and wind energy, the HySynergy project will produce around eight tonnes of hydrogen a day in its first phase, to be transported to a nearby refinery and to Germany. Hydrogen has been touted as a potential energy game-changer that could decarbonize industry and heavy transport.
unlike fossil fuels, which emit planet-warming carbon, hydrogen simply produces water vapor when burned. But producing so-called ‘green hydrogen’ remains a challenge, and the sector is still struggling to take off in Europe, with a multitude of projects abandoned or delayed.
