This article is an outline of the various efforts being made in Aichi Prefecture toward the popularization of hydrogen energy. For example, the Aichi Prefectural Government has settled on a plan to increase hydrogen refueling stations around the prefecture. We also founded a subsidy system for the development of the fuel cell vehicle (FCV) as well as hydrogen refueling stations. In addition, we provided a place for a portable hydrogen refueling station in the Aichi Prefectural Government parking lot. Through these efforts, there are now 17 hydrogen refueling stations within Aichi Prefecture, more than any other prefecture in Japan.
Algal bio-hydrogen production on Ama Town Initiative is one of subject of algal multi-faced use for contribution to the town industry, education and culture. In this article, we described on the significance of conservation of marine resources and global environment, and the background of the issue of Ama Town government to use algae in bioenergy production.
Kansai International Airport is looking to become an “environmentally advanced airport” equipped with the world’s top-class environmental performance and safety based on its smart island initiative and as such actively promotes environmental-friendly project with clean energy such as hydrogen. As part of the KIX hydrogen grid projects, demonstration operation of fuel-cell forklifts and hydrogen infrastructure in the international cargo area started in February 2015. This is the first time that such demonstration operation of fuel-cell forklift is undertaken in an airport in Asia. Besides, a large-scale hydrogen filling station is under construction in the second-phase airport island in KIX to open in January 2016. We are building of a hydrogen supply chain model inside airport and increase the more value of the airport environmental business.
In 2011, Saitama PRefecture began to implement leading-edge policies related to hydrogen energy, which can be PRoduced from a variety of energies including renewable energy resources, in order to start building a “hydrogen-energy society.”
This paper introduces the activities of Saitama’s "SPRint to a Hydrogen-Energy Society PRoject," an initiative started in 2015. This PRoject includes using a solar hydrogen charging station (SHS), which PRoduces hydrogen by using electricity of solar energy, on the PRefectural government campus
Yamaguchi Prefectural Government is making efforts for realization of “hydrogen leading prefecture”. We attracted the plant of the liquid hydrogen and the hydrogen station started operation in Shunan city recently. We have been working on industrial promotion by utilizing hydrogen.
High strength low alloy (HSLA) steels such as JIS-SCM and -SNCM steels, which have been proposed as candidate materials for the storage tank for hydrogen filling stations, are known to show decreases in tensile ductility and notch strength in gaseous hydrogen due to hydrogen embrittlement. However, if a method to utilize these steels to the ultimate of the resistance to hydrogen embrittlement could exist, it could be an effective technique that satisfies both the safety and the economy requirements for hydrogen filling stations. In this paper, crack growth behaviors of HSLA steels in gaseous hydrogen obtained to date were reviewed and summarized. The threshold stress intensity factor (KIH) obtained under rising load method was less than sustained load method. It was clarified that the acceleration of fatigue crack growth occurs around KIH obtained by rising load test. Finally, the safety evaluation method for hydrogen storage tank made of HSLA steel was proposed.
