Title:
エネルギー貯蔵システム
Document Type and Number:
Japanese Patent JP6932306
Kind Code:
B2
Abstract:
There is disclosed an energy storage system. In particular, there is disclosed a chemisorption based energy storage system, able to provide electricity, heating or cooling depending on the desired energy output. The energy storage system includes a first chemical reactor containing a first sorbent material and a second chemical reactor containing a second sorbent material. The first and second chemical reactors are in mutual fluid connection such that a refrigerant fluid can flow from the first chemical reactor to the second chemical reactor, and from the second chemical reactor to the first chemical reactor. The first and second chemical reactors are further provided with means for putting heat in to, or taking heat out of, the first and/or the second chemical reactors. A heat exchanger module is also provided. The heat exchanger module is configured to select from a plurality of available heat sources, a heat source having the highest temperature and an expander module selectively connected to the first chemical reactor and the second chemical reactor via the heat exchanger module. The heat source is arranged to heat the refrigerant fluid prior to the refrigerant fluid passing through the expander module, and the heat exchanger is configured to recover a surplus heat from the highest temperature heat source. The expander module is configured to expand the refrigerant fluid. The means for putting heat in to, or taking heat out of, the first and/or the second chemical reactors provides a flow of refrigerant fluid between the expander module and the first and second chemical reactors, and wherein the expander module is operable to expand the refrigerant fluid to provide a variable work output depending on energy storage requirements.
