While …
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.
Another energy management strategy for stand-alone PV hydrogen production systems has been proposed [ 18] with the aim ofreducing the battery size and loss by reducing the energy circulating in the battery, and the strategy has been validated in real operations.
The theoretical efficiency of this solar hydrogen production system is 36.5% (Kaleibari et al., 2019). However, the energy obtained from the full-spectrum utilization of solar energy is predominantly thermal energy, with an electrical energy to thermal energy ratio of less than 1:2.
An energy management strategy was proposed for a stand-alone PV coupled electrolytic hydrogen production system [17 ], and the feasibility of this energy management strategy wasverified by specific experimental cases.
Based on the energy management strategy of this system proposed above, the system produces hydrogen stablywhen the solar irradiance changes, i.e., the hydrogen production rate remains unchanged, and the constant electrolytic efficiency of 68.5% is obtained.
In this study, a solar photovoltaic-thermal hydrogen production system based on full-spectrum utilization is proposed. The concentrated sunlight is divided into two parts based on wavelength.
