One of the surprising climate stories of 2022 was the rapid emergence of hydrogen as an immediate, not just potential, decarbonization technology. Major and unprecedented investments, both from government and the private sector, were initiated this year in Europe, the U.S., China and Japan. But while hydrogen technology is growing in popularity, questions remain: Can it be one of the biggest breakthroughs for climate mitigation, or is it largely a distraction?
It’s likely a mixture: a viable, long-sought, low-carbon option for hard-to-electrify sectors like steel, chemicals and aviation, but also a clever oil industry ploy to extend the use of fossil fuels in sectors like power generation, road transport and home heating, which are more easily and affordably powered from the grid.
Only hydrogen that’s produced by using renewable power to split water molecules into…
Hydrogen made a surprising comeback in 2022 — but it’s still not the green fuel of the future
