Effect of hydrogen leakage on the life cycle climate impacts of hydrogen supply chains

open access: yesCommunications Earth & Environment
Abstract Hydrogen is of interest for decarbonizing hard-to-abate sectors because it does not produce carbon dioxide when combusted. However, hydrogen has indirect warming effects. In this work, we conducted a life cycle assessment of electrolysis and steam methane reforming to assess their emissions while considering hydrogen’s indirect warming

The climate benefit of a greener blue hydrogen [PDF]

open access: yesScientific Reports
Previous studies have demonstrated the potential benefit of a future hydrogen economy in terms of reducing CO2 emissions. The hydrogen leakage rate and the green hydrogen fraction in the mix were identified as key factors in maximising the climate ...

Combined warming index energy system analysis framework for methane leakage rate and carbon capture rate uncertainty [PDF]

open access: yesMethodsX
Fossil fuels dominate the production of hydrogen and will continue to contribute in a decarbonised future. Blue hydrogen production from natural gas with carbon capture and storage technology applied is seen as the major route for natural gas in a future

Climate consequences of hydrogen leakage [PDF]

open access: yes, 2022
Abstract. Hydrogen is quickly gaining attention as a “clean” fuel that can support a transition to a decarbonized energy system. Given the urgency to decarbonize global energy systems, governments and industry are moving ahead with efforts to increase hydrogen technologies, infrastructure, and applications at an unprecedented pace, including billions ...

Numerical simulation of leakage and diffusion of buried pure hydrogen/hydrogen-doped natural gas pipeline

open access: yesYou-qi chuyun, 2023
In order to study the diffusion characteristics of pure hydrogen/hydrogen-doped natural gas in the soil environment, a three-dimensional leakage model of the buried pure hydrogen/hydrogen-doped natural gas pipeline was established by Fluent software.

Research on hydrogen leakage and dispersion characteristics in indoor thermal stratification environment [PDF]

open access: yesE3S Web of Conferences, 2022
The leakage of hydrogen in a room is a key issue of hydrogen safety, and ventilation plays an important role in hydrogen dispersion. The hydrogen leakage usually builds a thermal stratification environment due to the low temperature of liquid hydrogen or

Characterization of High-Pressure Hydrogen Leakages

open access: yesVolume 2: Ceramics and Ceramic Composites; Coal, Biomass, Hydrogen, and Alternative Fuels, 2023
Abstract Reduction of gas turbines carbon emissions relies on a strategy for fueling the engines with pure or blended hydrogen. The major technical challenges to solve are i) the adjustments to the engine and in particular the combustion chamber and ii) a series of issues to solve to guarantee safe operations.
