Researchers at Hanze University of Applied Sciences in Groningen, Netherlands, have introduced an innovative system that combines hydrogen production, battery storage, and rooftop PV or small wind turbines for off-grid households. The system aims to store surplus renewable energy efficiently, with hydrogen generation and battery storage complementing each other. The proposed setup includes a PEM hydrogen electrolysis system, hydrogen storage tank, purification unit, fuel cell, and lithium-ion battery. By utilizing the fast-response capabilities of PEM electrolysis, the system ensures stable operation even in fluctuating renewable energy conditions. The research emphasizes the importance of properly drying and purifying hydrogen before use, highlighting the need for efficient operation. The simulation conducted on a typical Dutch household demonstrated the benefits of a hybrid approach, with a combination of wind and solar power proving to be the most cost-effective. The study suggests downsizing the electrolyzer and optimizing battery capacity to enhance system efficiency and reduce costs. Future research directions include testing the system on a larger scale and exploring integration with heat production. The findings were published in the International Journal of Hydrogen Energy, showcasing a promising solution for sustainable off-grid energy storage.
