Fukushima Renewable Energy Institute, AIST (FREA) was established in Koriyama city of Fukushima in April 2014. FREA aims are to be a global innovation hub concerning renewables, through creative “Fukushima” technologies. Renewable energies are valuable domestic energy resources for Japan and essential for the prevention of global warming as well as for sustainable development. There are high expectations for mass deployment of renewable energy, but its wide use raises various issues that must be solved, including output fluctuation, high cost and regional variability. FREA has been developing technologies for storing and utilizing a large amount of renewable energy that will help solve several energy issues facing Japan. We have been developing technologies for converting renewable electricity into hydrogen or hydrogen energy carriers (methylcyclohexane (MCH), ammonia, liquid hydrogen (LH2), etc.), which is utilized by generating electricity, heat, and hydrogen. These technologies are useful for stabilizing the power grid even when massive amounts of renewable energy are introduced in the future. The result will be the efficient use of a much greater amount of renewable energy regardless of the location and season.
In this report, the results of R&D for the hydrogen systems in FREA are introduced.
