Abstract: The present disclosure provides a fuel trading coordination technique that enables certification processes taking account of a supply chain for a fuel, such as hydrogen, and that meets fuel users' demands while ensuring their convenience. A fuel trading coordination device according to the present disclosure includes a storage device storing information of a plurality of fuel suppliers, and a controller that processes an order for purchasing a mix of a first type fuel and a second type fuel, the order being placed by a first type fuel user. The first type fuel and the second type fuel are fuels that are different in production method but can be used for the same purpose. The controller sends information of the order of the first type fuel user to a first supplier that supplies the first type fuel and to a second supplier that supplies the second type fuel.

Abstract: The invention provides a cogeneration system capable of adjusting a heat-to-electric power ratio not only in an increasing direction, but also in a decreasing direction. The cogeneration system includes: a power generation device configured to supply electric power; a first heat exchanger configured to exchange heat between exhaust of the power generation device and water, so as to lower a temperature of the exhaust and obtain steam from the water; a reformer configured to generate a reformed gas by the steam reacting with a fuel; a second heat exchanger configured to cool the reformed gas generated by the reformer by heat exchanging; a reformed gas supply device configured to supply the reformed gas cooled by the second heat exchanger to the power generation device; a distributor configured to supply the steam to at least one of the reformer and a heat utilization device; and a control device configure to adjust a heat-to-electric power ratio by changing a supply destination of the steam in the distributor.
