Special Issue Information

Dear Colleagues,

Hydrogen energy has been a controversial issue. Hydrogen is expected to be an alternative energy carrier, which can absorb fluctuations of electrical supply from renewable energies, such as photovoltaic cell and wind turbine, and can also be utilized in high-energy efficiency devices, such as fuel cells and hydrogen turbines. Despite tremendous efforts and publications on hydrogen energy technologies, there are still issues to be discussed and solved for the realization of a full-scale hydrogen economy.

This Special Issue covers a wide range of hydrogen technologies, such as hydrogen production, storage and transportation, and utilization. It will include gasification of fossil fuels and biomass, electrolyzers, fuel cells, fuel cell electric vehicles, etc., and their integrated systems. We welcome papers that comprehensively and critically examine the advantages and disadvantages, current problems, and future perspectives of technologies and systems.

We also invite papers dealing with, not only the technological aspects of hydrogen technologies, but also economic, industrial, and social issues. We welcome papers that design and assess hydrogen supply chains and energy systems with quantitative methodologies, including life cycle assessment and economic modeling. We also welcome papers dealing with qualitative aspects. Examples are case studies of social issues relating implementation of hydrogen energy system, transition management of energy systems, innovation ecosystems and the management of technology and innovation.

Topics of interests include, but are not limited to:

  • State-of-the-art of hydrogen energy technologies;
  • Life cycle assessment of energy technologies and systems;
  • Economic modeling of hydrogen energy systems;
  • Social issues relating implementation of hydrogen energy systems;
  • Transition management of energy systems;
  • Innovation ecosystem and management of technology and innovation.

Comprehensive risk assessment across multiple fields is required to assess the potential utility of hydrogen energy technology. In this research, we analyzed environmental and socio-economic effects during the entire life cycle of a hydrogen energy system using input-output tables. The target system included hydrogen production by naphtha reforming, transportation to hydrogen stations, and FCV (Fuel Cell Vehicle) refilling. The results indicated that 31%, 44%, and 9% of the production, employment, and greenhouse gas (GHG) emission effects, respectively, during the manufacturing and construction stages were temporary. During the continuous operation and maintenance stages, these values were found to be 69%, 56%, and 91%, respectively. The effect of naphtha reforming was dominant in GHG emissions and the effect of electrical power input on the entire system was significant. Production and employment had notable effects in both the direct and indirect sectors, including manufacturing (pumps, compressors, and chemical machinery) and services (equipment maintenance and trade). This study used data to introduce a life cycle perspective to environmental and socio-economic analysis of hydrogen energy systems and the results will contribute to their comprehensive risk assessment in the future.

Hydrogen is a promising energy carrier in the clean energy systems currently being developed. However, its effectiveness in mitigating greenhouse gas (GHG) emissions requires conducting a lifecycle analysis of the process by which hydrogen is produced and supplied. This study focuses on the hydrogen for the transport sector, in particular renewable hydrogen that is produced from wind- or solar PV-powered electrolysis. A life cycle inventory analysis is conducted to evaluate the Well-to-Tank (WtT) GHG emissions from various renewable hydrogen supply chains. The stages of the supply chains include hydrogen being produced overseas, converted into a transportable hydrogen carrier (liquid hydrogen or methylcyclohexane), imported to Japan by sea, distributed to hydrogen filling stations, restored from the hydrogen carrier to hydrogen and filled into fuel cell vehicles. For comparison, an analysis is also carried out with hydrogen produced by steam reforming of natural gas. Foreground data related to the hydrogen supply chains are collected by literature surveys and the Japanese life cycle inventory database is used as the background data. The analysis results indicate that some of renewable hydrogen supply chains using liquid hydrogen exhibited significantly lower WtT GHG emissions than those of a supply chain of hydrogen produced by reforming of natural gas. A significant piece of the work is to consider the impacts of variations in the energy and material inputs by performing a probabilistic uncertainty analysis. This suggests that the production of renewable hydrogen, its liquefaction, the dehydrogenation of methylcyclohexane and the compression of hydrogen at the filling station are the GHG-intensive stages in the target supply chains.
