Is green hydrogen the answer to the climate crisis? | DW Documentary

Green hydrogen produces zero emissions and many believe it holds the key to limiting global warming. So is it the big hope for the future or a multi-billion euro mistake? Many believe green hydrogen could provide a miracle solution for countries around the world seeking to decarbonize their economies. But the technology is still in its infancy. Generating sufficient quantities of green hydrogen would require a lot more renewable energy than is currently available. Right now, almost all hydrogen is produced using natural gas in a process that generates large amounts of carbon dioxide. Green hydrogen, by contrast, is climate neutral. It’s derived using renewable energy. The principle itself is not new but has, at yet, only found limited usage. Engineers at the German Aerospace Center are now working with the world’s largest artificial sun to try to produce hydrogen without any electricity at all, using only light. If they can succeed, it would allow large-scale production of this valuable gas in countries that
