In a cold region during winter, energy demand for residential heating is high and energy saving, the discharge of greenhouse gases, and air pollution are all of significant concern. We investigated the fundamental characteristics of an energy storage system with a GHB (gas hydrate battery) in which heat cycle by a unique change in state of gas hydrate operates using the low-temperature ambient air of a cold region. The proposed system with the GHB can respond to a high heat to power ratio caused by a small-scale CGS (cogeneration system) that is powered by a gas engine, a polymer electrolyte fuel cell, or a solid oxide fuel cell. In this paper, we explain how the relation between fossil fuel consumption and heat to power ratio of the different types of systems differ. We investigated the proposed system by laboratory experiments and analysis of the characteristics of power load and heat load of such a system in operation in Kitami, a cold district in Japan. If a hydrate formation space of 2 m(3) is introduced into the proposed system, 48%-52% (namely, power rate by green energy) of total electric power consumption is supplied by the GHB.
