Flipping the switch on ammonia production: Process generates electricity instead of consuming energy

Nearly a century ago, German chemist Fritz Haber won the Nobel Prize in Chemistry for a process to generate ammonia from hydrogen and nitrogen gases. The process, still in use today, ushered in a revolution in agriculture, but now consumes around one percent of the world`s energy to achieve the high pressures and temperatures that drive the chemical reactions to produce ammonia.
