Abstract: The community system includes a hydrogen source, a hydrogen storage, an FC power generating facility, a hydrogen filler, a house group that uses electric power supplied from the FC power generating facility and hydrogen supplied from at least one of the hydrogen source and the hydrogen storage, and a management system that manages hydrogen in the community system. The hydrogen source is a hydrogen producing device that produces hydrogen using waste heat generated in a commercial and industrial installation or produces hydrogen from by-product gas produced in the commercial and industrial installation.

Abstract: The community system includes a hydrogen source, a hydrogen storage, an FC power generating facility, a house group that uses hydrogen supplied from at least one of the hydrogen source and the hydrogen storage, and a management system that manages hydrogen in the community system. The management system manages hydrogen possession allocated to each house in the house group.

Abstract: A hydrogen supply and demand matching system comprises a plurality of hydrogen utilizing districts each including a hydrogen utilizing facility, and a management system configured to manage an amount of hydrogen in each of the plurality of hydrogen utilizing districts. The management system (a) estimates a state of supply and demand of hydrogen in each of the plurality of hydrogen utilizing districts, and (b) proposes exchange of hydrogen among the plurality of hydrogen utilizing districts in accordance with the state of supply and demand in each of the plurality of hydrogen utilizing districts.

Abstract: The community system includes a hydrogen source, a hydrogen storage, an FC power generating facility, a house group that uses electric power supplied from the FC power generating facility and hydrogen supplied from at least one of the hydrogen source and the hydrogen storage, and a management system that manages hydrogen in the community system. Each house in the house group is provided with a cooking-related appliance that uses hydrogen.

Abstract: An FCV (fuel cell vehicle) dispatch system comprises a FCV management institution including an FCV management device configured to manage a plurality of FCVs, and a dispatch management system configured to manage dispatch of the plurality of FCVs. The dispatch management system (a) receives available FCV information about at least one FCV that is available for dispatch, from the FCV management device, (b) receives power shortage information indicating occurrence of a power shortage, from a power shortage area where the power shortage has occurred, (c) selects at least one FCV suitable for resolving the power shortage in the power shortage area, based on the available FCV information and the power shortage information, and (d) sends a dispatch request for dispatching the at least one selected FCV to the power shortage area, to the plurality of FCV management device.

Abstract: The community system includes a hydrogen source, a hydrogen storage, an FC power generating facility, and multiple house groups that use hydrogen supplied from at least one of the hydrogen source and the hydrogen storage. The FC power generating facility is located at a position facing all the multiple house groups, or a position facing all the multiple existing house groups and a planned site where a new house group is to be built.

Abstract: A trailer rental system comprises a trailer station provided with a trailer mounted with a hydrogen tank and a management apparatus configured to manage the trailer, the management apparatus performing rental operation of the trailer in response to a trailer rental request being received from outside.

Abstract: Contaminants are efficiently purified without affecting the environment or necessitating the performance of any post-treatments such as pH adjustment that would be used to prevent environmental impact, even when the contaminated soil is highly viscous. In the method of purifying contaminated soil by microorganisms according to the present invention, contaminated soil mainly comprising clay or silt and containing trichloroethylene as a contaminant is dug out, and then temporarily placed on the ground (step 101). Next, perlite 2, which is an inorganic soil-improving material, the soil-improving material, and degradation microbes 3 degrading trichloroethylene are added to the contaminated soil 1 (step 102). The contaminated soil is subsequently mixed by agitation, so as to cause the perlite 2 to absorb pore water contained in the clay or silt (step 103). Next, aeration is performed to inject air into the contaminated soil 1, thereby microbially degrading trichloroethylene (step 104).
