Hybrid energy system combining renewable sources with hydrogen energy storage

Abstract

UniGRID's N611 platform is a hybrid multistate system for reliable energy supply, where in its operating state 2 it is possible to store energy that would otherwise be wasted. For the use of this energy, hydrogen storage is proposed. In this work, an automated system was developed for low-scale green hydrogen generation by means of Horizon's "Renewable Energy Education Set", using control valves and level sensors, guaranteeing the reliability of the green hydrogen generation process. Also, a graphical interface was developed for the visualization of the measured data, which allows the user's handling and manipulation. Additionally, since the stored hydrogen can be used as an energy source, which implies a change in the operating states of the N611 platform, a joint operation strategy was developed between the different algorithms present in the N611 platform to guarantee the intelligent change between the different operating states of the system.
