Hydrogen Energy Group

Mission of the group

Hydrogen energy is an important way to prevent global warming and ensure energy security. The reason is that hydrogen, which is compatible with electric power, is a unique energy carrier as it emits no CO2 when used, and its resources are evenly accessible in the world. Therefore, to establish hydrogen production technology without CO2 emission, namely using renewable energy or nuclear energy, will be a great contribution to prevention of global warming.
Economically feasible large-scale hydrogen energy systems, however, have not yet been established to date. And, further technological development and sophistication of hydrogen systems are necessary to realize the massive and efficient supply and utilization of hydrogen at an affordable cost.
From a long-term perspective, the Hydrogen Energy Group contributes to formulation of Japan’s energy strategy and also contributes to the hydrogen-related industries through assessing viability of hydrogen energy systems, identifying challenges in technological development and showing a technological development path for realization.
When the WE-NET Project, a hydrogen energy part of the New Sunshine Program, was launched in 1993, WE-NET Center was simultaneously established in the Institute of Applied Energy (IAE). Since then, the Hydrogen Energy Group has been continuously engaged in a broad range of research and study activities. The recent research and study areas include study on CO2 -free hydrogen energy systems, development of hydrogen technology, assessment of hydrogen demand and strategy for widespread use of hydrogen. The group’s activities also include dissemination and better understanding of hydrogen-related knowledge among the public.

Future challenges

As global warming countermeasures and stable supply of energy are pressing issues, the Hydrogen Energy Group undertakes research and study in the following areas.

  • Research and study on the significance of large-scale introduction of CO2 -free hydroge
  • Study on large-scale introduction of CO2-free hydrogen systems
    • Research and study on viability of large-scale production systems of CO2-free hydrogen
      (Primary energy used as raw materials: renewable energy, fossil fuels, nuclear energy, etc.)
    • Research and study on viability of large-scale and long-distance transportation systems for CO2-free hydrogen
      (Various energy carriers: liquid hydrogen, organic hydride, ammonia, etc.)
    • Research and study on viability of technology for large-scale utilization of CO2-free hydrogen
      (Fuel cell vehicles, fuel cells for industrial and commercial/residential uses, large-scale power generation, gas turbines, etc.)
  • Study on CO2-free hydrogen and demand forecast
  • Comparative survey on hydrogen energy systems with other energy systems
  • Research and study on viability of large-scale introduction of renewable energy combined with hydrogen energy systems
  • Breakthrough technologies and developing roadmaps
  • Research on innovative hydrogen-related technologies including fuel cells both at home and abroad

Study approaches

In addition to the administration support on technological issues and activities on hydrogen energy, the group is conducting researches in cooperation with 3
private companies as follows.

  • Based on technical strategy, study the future technical trends and conduct technology evaluations.
  • Propose new projects in collaboration with private companies to the government or the New Energy and Industrial Technology Development Organization (NEDO) and launch new activities.
  • Form a study group with businesses, research organizations and universities on specific themes and exchange and share the relevant information which will lead to creation of projects.
