Life-cycle carbon-intensity mapping for hydrogen-driven energy and economy

Year: 2024

Type: article

Abstract: Innovative approaches on clean alternative energy sources are important for future decarbonization. Electrification and hydrogen energy are crucial pathways for decarbonization in both transportation and buildings. However, life-cycle stage-wise carbon intensity is still unclear for both hydrogen- and electricity-driven energy. Furthermore, systematic evaluation on low-carbon transition pathways is insufficient specifically within the Internet of Energy that interfaces hydrogen and electricity. Here, a generic approach is proposed for quantifying life-cycle stage-wise carbon intensity of both hydrogen- and electricity-driven energy internets. Life-cycle decarbonization effects on vehicle pathways are compared with traditional vehicles with internal-combustion engines. Techno-economic and environmental feasibility of the future advanced hydrogen-driven Internet of Energy is analyzed based on net present value. The region-wise carbon-intensity map and associated decarbonization strategies will help researchers and policymakers in promoting sustainable development with the hydrogen economy.
