Production, Storage, and Use of Green Hydrogen for Clean Energy

This project involves designing a green hydrogen system that incorporates production, storage, and an end-use application. Our primary objective is to use the system to power a hospital while maintaining stability through the utilization of renewable energy and minimization of emissions. The system consists of a proton-exchange membrane (PEM) electrolyzer that splits water into hydrogen and oxygen gas, a solid-state storage system that employs metal hydrides, and a PEM fuel cell that converts chemical energy directly into electrical energy. The fuel cell chosen for this system has a capacity to supply 5 MW of power. With continuous operation, it can produce approximately 120 MWh/day of energy. At the same time, the hydrogen production rate from the electrolyzer reaches 2,570.4 m3/day, with a maximum storage capacity of approximately 8.86 m3 utilizing titanium manganese alloy (TiMn2) as the metal hydride. In conclusion, the proposed green hydrogen production system, incorporating PEM electrolysis, metal hydride storage, and a PEM fuel cell, presents a promising solution for sustainable hospital energy needs.
