The growth of solar PV and energy storage technologies, which have become the “absolute driving force, the cornerstone” of the global energy transition, is being hampered by “our 100-year-old grids and power markets”, the GSC report said. Solar thermal power generation, with its regulation characteristics comparable to conventional thermal power units, can quickly and deeply participate in power grid peak shaving and frequency modulation, thereby enhancing the flexibility of the power system. It is a promising renewable energy. Those groups are sending up a warning flare to alert Americans to a critical bottleneck to renewable development. There is a major disconnect between the goals of numerous states, such as Virginia, to achieve zero-carbon electric grids by 2050 and the ability of the entities overseeing the electric. The growth of global energy demand and the aggravation of environmental pollution have prompted the rapid development of renewable energy, in which the solar photovoltaic/thermal (PV/T) heat pump system, as a technology integrating photovoltaic power generation and thermal energy conversion, has. Global grids have failed to keep pace with renewable energy technologies and have become the “bottleneck of the energy transition”, according to a new policy report from the Global Solar Council (GSC).
