摘要

清洁替代能源的创新方法对于未来的去碳化非常重要。电气化和氢能是交通和建筑领域去碳化的重要途径。然而,氢能和电力驱动能源的生命周期阶段性碳强度仍不明确。此外,对低碳过渡途径的系统评估也不够充分,特别是在氢能和电力相互结合的能源互联网中。本文提出了一种通用方法,用于量化氢能和电力驱动能源互联网的生命周期阶段性碳强度。并将车辆生命周期脱碳效果与传统内燃机车辆进行了比较。根据净现值分析了未来先进的氢驱动能源互联网在技术经济和环境方面的可行性。区域碳强度图和相关的脱碳战略将有助于研究人员和政策制定者利用氢经济促进可持续发展。

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

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

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.
