Abstract

An individual cogeneration plant includes a collector for collecting solar energy and transmitting heat generated from the solar energy, and a boiler in communication with the collector for generating steam from water using the heat transmitted from the collector. A generator communicates with the boiler for generating electricity from the steam generated by the boiler, and unused electricity generated by the system can be stored as hydrogen gas for future use, or transferred to an external main power grid. A control unit can be programmed to make determinations regarding an optimum setting for operation based on current conditions. Multiple cogeneration plants can be interconnected with each other and the main power grid. The individual cogeneration plants can provide power to each other and the main power grid based on current user demands.
