Green ammonia (NH3) will have a versatile role in the decarbonisation of large sectors of the global economy. Of these sectors green ammonia will likely have the most competitive potential in decarbonising long-duration energy storage, regional energy and hydrogen transport, shipping propulsion fuel, and replacing existing brown ammonia production for fertiliser and other chemicals. In this presentation, we introduce our modelling on the cross-sector integration of green ammonia into large-scale energy systems, with a case study of India. In the power sector, ammonia may play a role in seasonal storage, system resilience, and electricity import/export. We co-developed the world’s first…
