The basic strategy in the fight to limit climate change is to power everything with electricity generated from wind, solar or other clean sources.
But there’s a problem: Some things can’t easily run on electricity. Think steel mills, cement plants and long-distance passenger jets. They need a clean fuel that can be stored and burned, sometimes at high temperatures. This is where green hydrogen comes in. Depending on who you ask, this controversial technology is either a crucial piece of the puzzle to reduce greenhouse gases or an overpriced, overhyped distraction.
