The integrated system of photovoltaic power generation and P2H: a comprehensive review

This article provides a comprehensive overview of the technological foundations and research status about the integration of photovoltaic power generation and hydrogen energy storage systems. In recent years, the combination of these two cutting-edge technologies has garnered significant attention, primarily due to the limitations of current power plants in accommodating large-scale energy storage. This integration not only aligns with China's overarching "dual carbon" policy objectives but also holds the potential to address the intermittent nature of renewable energy sources and facilitate long-term energy storage. The primary objective of this article is to delve into the various types of photovoltaic panels, their fabrication methods, and the ongoing research advancements in flexible battery technologies. Furthermore, a comparative analysis is conducted between hydrogen energy storage technology and lithium-ion battery energy storage technology, followed by an in-depth examination of the current development status and the challenges faced by the photovoltaic-hydrogen system.
