> Ammonia doesn’t burn well on its own, he notes, and converting exported ammonia back to hydrogen for steel plants or fuel-cell vehicles requires a lot of energy. “You’re using energy to import energy. If you need green hydrogen in Europe, it’s probably cheaper to make green hydrogen in Europe,” Tengler concludes. Surely hydrogen makes more sense for in-situ energy storage at solar and wind farms to smooth out supply during dark/windless times
