On September 10, a ship docked at the German port of Hamburg carrying a little-known fuel that’s being billed as a potential clean answer to Europe’s energy woes: blue ammonia. Made from hydrogen, it can also be burned without producing any emissions of planet-warming carbon dioxide and has the advantage of being easier to transport.
Europe’s first test cargo is destined for the continent’s largest copper producer, Aurubis AG, under a deal struck with the United Arab Emirates just three weeks after Russia’s invasion of Ukraine upended global energy markets. The second shipment will depart within weeks, Mariam Almheiri, the UAE's Minister of Climate Change and Environment, said last week.
