Hydrogen has an essential role in a sustainable future. Firstly, the energy sector can be decarbonized with efficient and clean power generation from hydrogen fuel cells. Secondly, hydrogen has a high gravimetric density and is an efficient energy storage medium for the energy and transportation sectors. In addition to this, hydrogen is an important chemical feedstock for various industries in order to decrease their carbon footprints. Yet, hydrogen for all these applications must be obtained from a sustainable source.

This Research Topic addresses the sustainable production of high purity hydrogen for energy, fuel and commodity applications. The focus is on hydrogen production from renewable sources such as solar and biomass. Developments in other fields such as gas separation, synthetic renewable hydrocarbons, hydrogen carriers that enable the hydrogen production and application are also of interest. We also encourage discussions in a system perspective on how hydrogen production from current and future energy profiles can address the sustainable development goals (SDGs).

Until now, the majority of hydrogen production is from fossil fuel reforming, which requires further purification to meet the purity standard for various applications. Moreover, the carbon produced should be captured to decrease the environmental impacts of fossil fuel based hydrogen production. This type of hydrocarbon based technology with carbon capture can provide an intermediate step towards sustainable hydrogen production, and is also considered in this Research Topic.

The ultimate objective of this Research Topic is to gain insights on the latest developments of sustainable hydrogen production and applications in both academia and industry, and to understand the bottlenecks for large scale deployment of these technologies. The Topic Editors encourage submissions of original research articles, short communications, industrial and country/region case studies, and review articles from different stakeholders in the fields of fuel cells, hydrogen storage and production, and carbon capture, storage and utilization. This Research Topic covers but is not limited to the following concepts:
- Hydrogen production from water splitting, using technologies such as photoelectrolysis, proton exchange membranes, intermediate and high temperature electrolysis cells, solar thermochemical hydrogen production
- Hydrogen separation methods, such as adsorption, absorption and membrane
- Hydrogen carriers such as ammonia, methane, methanol and biogas
- Catalyst developments, component designs and system innovations related with sustainable hydrogen production
- Techno-economic and life-cycle analysis of the societal impacts of sustainable hydrogen production
- Analysis and evaluation of hydrogen-based economics


Keywords: hydrogen, sustainability, catalysis, purification, solar fuel
