Jinghui Ting shares with you the solar energy R & D shift to concentrated power generation

According to the MIT Technology Review magazine, the US Department of Energy recently announced an investment of US $ 62 million to increase the research and development of another major technology in the solar industry-concentrating solar power to overcome solar grid stability, repairability, and electrical energy. Key challenges such as storage.

At present, solar power plants are mainly based on two technologies to convert solar energy into electricity: one is photovoltaic power generation technology, which needs to be equipped with expensive battery packs or external energy storage technology, and can only operate when the sun is shining; the second is concentrated light The solar power generation technology focuses the sunlight through a lens and the like, and uses the obtained energy to convert water into steam to drive the turbine. The solar energy is partially converted into thermal energy and stored in a molten salt tank equipped with the system, which can continuously supply power at night or rainy days.
