Hydrogen-electricity hybrid energy pipelines for railway transportation: Design and economic evaluation

International Journal of Hydrogen Energy, Год журнала: 2024, Номер 61, С. 251 - 264

Опубликована: Март 1, 2024

With the decarbonization and electrification of modern railway transportation, demand for both high-capacity electrical energy hydrogen fuel is increasingly high. A novel scheme was proposed from liquid production by surplus wind solar energy, to hydrogen-electricity hybrid transmission transportation. The 100 MW pipeline designed with 10 kA/1.5 kV superconducting DC cable electricity cryogenic layers nitrogen, showing strong capability in transmitting "electricity + cold chemical energy" simultaneously. Economic evaluation performed respect equipment capacity, costs, sensitivity profitability analysis. discount rate 8%, dynamic payback period 7.1 years. Results indicated that shortest 4.8 years, maximum distance 93 km. Overall, this article shows concept design pipelines, proves technical economic feasibilities future bulk

Life cycle assessment of green hydrogen production through electrolysis: A literature review

Sustainable Energy Technologies and Assessments, Год журнала: 2024, Номер 69, С. 103923 - 103923

Опубликована: Июль 31, 2024

This study reviews the electrolysis techniques for green-hydrogen (GH2) production, with primary focus on their environmental sustainability implications. Different stages of GH2 value chain are characterized regarding life cycle analysis (LCA), presenting methods, materials, energy sources, and efficiency. Qualified LCA results would lead to proper decision-making, which depends input choices data quality used. Therefore, inventory useful technical production in studies reviewed. Also, recent developments toward potentially enhancing discussed. The showed that solar wind energies as most promising sources lower Global Warming Potential (GWP) turbine cases. reported impacts (EIs) proton-exchange membrane (PEM) technology. There is still limited comparing various EIs (e.g. freshwater eutrophication) accompanying costs. However, it recommended consider H2 mainly efficiency, consumption lifetime along miniaturization. future may final use produced fuel cells), heat recovery materials recycling complete visibility towards optimizing efficiency EIs.

Perspectives and Outlook of E-fuels: Production, Cost Effectiveness, and Applications

Energy & Fuels, Год журнала: 2024, Номер 38(9), С. 7665 - 7692

Опубликована: Апрель 23, 2024

With the introduction of EU's "ban on combustion" proposal in 2035, sale new fossil fuel vehicles will soon be comprehensively prohibited. The use e-fuels has become best means for survival and continuation internal combustion engines, while also responding to call carbon neutrality. This review studies how raw materials required different can obtained through assistance renewable energy or various net-zero emission routes, elaborates synthesis methods, economics, challenges faced by such as e-methanol e-ammonia. E-fuels have a wide range market applications, including but not limited road transportation, aviation, shipping, some transportation already chosen their fuel. By summarizing technoeconomic analysis e-fuels, this aims provide referable methods multiple options future large-scale production well insights subsequent application improvement e-fuels.
