Introduction of Solar Thermal Electricity

Solar Thermal Electricity (STE), also known as Concentrating Solar Power (CSP) or a new way of solar energy utilization, uses a large number of mirrors to focus the direct sunlight, heat the working medium and store it, and then uses the high-temperature working medium to generate high-temperature and high-pressure steam to drive the steam turbine generator unit to generate electricity. Due to the existence of large-scale thermal storage systems, solar thermal power generation can achieve continuous, stable, and schedulable high-quality power output, which has broad prospects for development. Among various forms of photo-thermal power generation technology, tower type molten salt energy storage photo-thermal power generation has become the most mainstream photo-thermal power generation technology route due to its high system efficiency and large cost reduction space.

Green, clean and pollution-free

Photothermal power generation is a truly green and clean renewable energy, which can completely get rid of the dependence on fossil energy and fundamentally solve the energy problems, air pollution problems and climate change problems faced by human society.

Continuous, stable and schedulable

Compared with traditional intermittent renewable energy such as photovoltaic power generation and wind power generation, photothermal power generation is a grid-friendly power source. Based on large-scale thermal storage system, photothermal power generation can provide continuous, stable and schedulable high-quality power output, and can assume the role of basic load and peak load in the power system, so as to achieve the goal of high proportion of renewable energy.

Strong long-term economy

At present, solar thermal power generation is still in the early stage of industrial development. With the expansion of the industrial scale, the maturity of the industrial chain and technological progress, its power generation cost has a huge space for decline. In the long term, it can achieve parity online.

Strong industrial driving force

Photothermal power generation can absorb a large amount of excess capacity in cement, steel, glass, chemical, machinery and other industries, and promote the development of high-end equipment, automation, software and other industries.
