Production and Utilization of Hydrogen and Future Aspects

Dear Colleagues,

Declining petroleum resources, coupled with its adverse impact on the environment in terms of greenhouse gas generation, have accelerated the need to find alternatives based on renewable and sustainable energy resources. In this prospect, hydrogen has emerged as a potential sustainable option due to the following reasons. These are that (i) the energy sector can be decarbonized with efficient and clean power generation from hydrogen fuel cells and (ii) hydrogen has a high gravimetric density and is an efficient energy storage medium for the energy and transportation sectors. Additionally, hydrogen remains as an important chemical feedstock for various industries in order to decrease their carbon footprints. However, hydrogen for all these applications must be obtained from a sustainable source.

The present research topic aims to address the sustainable production of high-purity hydrogen for energy, fuel and commodity applications, while also emphasizing hydrogen production from renewable sources such as solar and biomass. Developments in other fields such as gas separation, synthetic renewable hydrocarbons, and hydrogen carriers that enable hydrogen production and application are also of interest. Discussions on how hydrogen production from current and future energy profiles can address the sustainable development goals is strongly encouraged.

The primary objective of this research topic is to gain insights into the latest developments of sustainable hydrogen production and applications in both academia and industry, and to understand the challenges that are associated with its large-scale deployment as technologies. The topic editors encourage submissions of original research articles, short communications, and review articles from the experts in the fields of fuel cells, hydrogen storage and production, 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 production from the biomass;
• Hydrogen carriers such as ammonia, methane, methanol and liquid organic hydrogen carriers (LOHC);
• Catalyst developments, component designs, and system innovations for sustainable hydrogen production;
• Technoeconomic and life-cycle analysis of the societal impacts of sustainable hydrogen production;
• Analysis and evaluation of hydrogen-based economics.
