Abstract: Photovoltaic-coupled hydrogen production technology can use the waste and abandoned electricity generated by photovoltaics to produce hydrogen on a large scale, which reduces the hydrogen production cost, improves the overall system efficiency, and plays an important role in the transformation and upgrading of photovoltaic systems. By analyzing the development status of domestic photovoltaic coupled hydrogen production technology, its operation performance and system economy were evaluated. Finally, according to the characteristics of Northwest China, a technical route suitable for photovoltaic coupled hydrogen production technology demonstration was proposed.
