Applicability Analysis And System Efficiency Study Of Light-Hydrogen Storage System In Handan Area

The acceleration of the industrialization process has led to more and more human demand for fossil energy,causing serious disasters to the environment.Energy shortages and environmental pollution have led people to focus on the development and utilization of renewable energy.Solar energy is clean and pollution-free,and the amount of resources is huge,which has gradually become the focus of attention.Hydrogen has high calorific value,can be stored for a long time,and is environmentally friendly.Hydrogen storage is the best choice for distributed generation energy storage.This paper focuses on the richness of solar energy resources in the Han Dan region and the research on photovoltaic power generation hydrogen storage system.This paper analyzes the richness of solar energy resources in the area,and analyzes the data collected by an automatic weather station.I find that the solar energy resources in the area are rich,the solar radiation shows seasonal changes,and the summer radiation is the highest.In the second quarter,the amount of radiation in winter is the lowest.In terms of heat conditions,solar energy utilization efficiency is high in the region,and the potential for development and utilization is huge.The equivalent circuit of the solar photovoltaic cell is established.According to the technical parameters of the solar photovoltaic cell,the U-I curve of the solar photovoltaic cell is obtained,and the maximum power point exhibits a linear distribution characteristic.Then,through the control variable method design experiment,the electrical characteristics of the electrolytic cell are analyzed.It is found that the increase of the bath temperature,the decrease of the electrolyte flow rate,and the increase of the internal pressure of the system will lower the voltage,but in order to protect the electrode,the temperature needs to be controlled at 55°C,the electrolyte flow rate is controlled at 300L/h,and the internal pressure of the system is generally 1.8MPa.Finally,the concept of enthalpy is introduced to analyze the energy conversion efficiency of the system.By establishing the black box model and the gray box model,the enthalpy efficiency of the whole system is 8.37%.Under the ignoring the photoelectric conversion link,the system efficiency can reach 52.34%.The waste heat generated by the waste heat of the electrolytic cell is 80.23%,and the enthalpy loss coefficient is 38.24%,which is the weakest link for the system.
