Civil aviation provides an essential transportation network that connects the world and
supports global economic growth. To maintain these benefits while meeting environmental …

This paper reviews recent optimization models for hydrogen supply chains and production.
Optimization is a central component of systematic methodologies to support hydrogen …

The feasibility of the global energy transition may rest on the ability of nations to harness
hydrogen's potential for cross-sectoral decarbonization. In countries historically reliant on …

Hydrogen will play a key role in decarbonizing economies. Here, we quantify the costs and
environmental impacts of possible large-scale hydrogen economies, using four prospective …

Automotive electrification holds the promise of mitigating transportation-related greenhouse
gas (GHG) emissions, yet at the expense of growing demand for critical metals. Here, we …

Hydrogen is recognised as an important future energy vector for applications in many
sectors. Hydrogen is an indirect climate gas which induces perturbations of methane, ozone …

Hydrogen (H2) is expected to play a crucial role in reducing greenhouse gas emissions.
However, hydrogen losses to the atmosphere impact atmospheric chemistry, including …

Potential carbon neutrality of the global trucking, ship** and aviation sectors by 2050
could be achieved by substituting fossil fuels with renewable hydrogen and synthetic fuels …

Hydrogen is often suggested as a universal fuel that can replace fossil fuels. This paper
analyses the feasibility of direct hydrogen utilisation in all energy sectors in a 100 …

In this study, a two-dimensional chemistry-transport model (TROPOS) has been employed to
examine the sensitivity of the global warming potential (GWP) for H 2 to the size of the …
