Green hydrogen systems encompass the production, distribution, storage, and end-use of hydrogen generated from low-carbon energy sources, primarily via water electrolysis powered by renewables. The field examines techno-economic performance, life-cycle environmental impacts, and resource demands such as water use, while integrating hydrogen into industrial processes, heavy transport, and power systems. Research also addresses infrastructure planning, supply chains for hydrogen and derived fuels like ammonia, and the role of hydrogen in large-scale decarbonization strategies for sectors such as steel and gas-fired power.
