The hydrogen energy storage system within the microgrid consists of an electrolyzer, a hydrogen storage tank, a fuel cell stack, and two DC/DC converters. The buck converter allows the EL to consume the electric power to produce hydrogen, which is stored in the HST.
The electric energy storage system uses a supercapacitor module, which is connected to the bus with a bidirectional buck-boost converter for consuming or supplying the electric power. The hydrogen energy storage system within the microgrid consists of an electrolyzer, a hydrogen storage tank, a fuel cell stack, and two DC/DC converters.
To manage the power and hydrogen flows within the microgrid and coordinate the coupling between the microgrid and the hydrogen refueling station, this paper proposes an energy management framework for the electric-hydrogen system shown in Fig. 1 based on two preliminary studies , .
Conclusion This paper proposes an energy management framework for an electric-hydrogen hybrid energy storage system. The outer layer of the framework optimizes the hydrogen flow from the microgrid to the hydrogen refueling station.
The whole system is controlled by the microgrid system supervisor. Operative tests at nominal power show that the round-trip efficiency of the hydrogen energy storage system at full power is ca. 10% in a pure electric operation and ca. 24% in a heat cogeneration operation. At half power these values reduce to 9.5% and 18%, respectively.
On top of properly managing the energy within the microgrid, the production, storage, transportation, and utilization of hydrogen also need to properly coordinated. In fact, islanded or grid-connected microgrids can be used to produce hydrogen or even serve as a hydrogen refueling station if configured properly.
