What happened

New catalyst unlocks carbon-free ammonia heat for steel, cement and chemicals Gaby Clark Scientific Editor Andrew Zinin Lead Editor A single-atom platinum catalyst lights ammonia at 200 °C and keeps it burning steadily at 1,100 °C with low NOx, generating…

Why it matters

Ammonia is a tempting fuel for the world's hottest jobs.

Common ground

It can be made from air, water and renewable electricity, stored as a liquid and shipped using know-how industry already has.
