Hydrogen storage offers a potential solution by acting as a long-term storage medium that can absorb excess energy during periods of high solar generation and release energy during periods of low generation. However, the challenge lies in ensuring that hydrogen production and consumption are properly coordinated with grid demand.
A 43.2 % thermal energy recovery ratio of the system reaction heat was achieved by a 24-h operating cycle that replicated nighttime hydrogen generation and daytime electrical production . The viability of incorporating MH-based hydrogen storage into a solar hydrogen energy system that runs on its own was investigated .
One promising approach is coupling PV systems with hydrogen production infrastructure. Green hydrogen, produced via electrolysis powered by renewable energy, is increasingly recognized as a key player in decarbonizing hard-to-abate sectors, providing a versatile energy carrier and renewable energy storage solution.
Additionally, artificial intelligence (AI)-based algorithms are being explored to predict energy demand and optimize the distribution of energy between hydrogen production and storage systems. Integrating solar hydrogen into energy systems demands a comprehensive analysis of strategies to enhance system-level efficiency.
