The rapid development of solar batteries

At present, as the cost of photovoltaic power generation and the price of solar batteries continue to decline, in order to maintain the competitiveness of CSP technology, CSP developers have begun to pay more and more attention to the performance improvement, standardization of power stations, and large-scale deployment to reduce power generation costs.

The rapid development of solar batteries

 

With the continuous development of renewable energy around the world, the installed capacity of wind power and photovoltaics continues to rise. To ensure that the grid remains balanced, it is necessary to add additional adjustable power or configure energy storage systems such as solar batteries to eliminate the shortcomings of intermittent renewable energy. . Whether to choose a CSP station that can be equipped with a cost-effective heat storage system as the basic load for peak shaving, or to choose intermittent energy sources such as photovoltaic or wind power to configure storage batteries for energy storage may ultimately be determined by their respective economics. Therefore, CSP developers must go all out to reduce power generation costs so that they can compete with natural gas power generation, photovoltaic and solar battery systems.

According to the International Renewable Energy Agency (IRENA), by 2025, the levelized cost of power generation (LCOE) of trough CSP technology will drop by 37% to $90/MWh, and the cost of tower CSP technology will drop by 43 % To $80/MWh; while the cost of photovoltaic power generation will drop to $60/MWh, a decrease of 59%; the cost of onshore wind power will drop to $50/MWh, a decrease of 26%, and the cost of power generation for the latter two will continue to remain at Under CSP.

In places with good solar radiation resources, photovoltaic power generation technology equipped with a few-hour energy storage system is currently regarded as the most economical solar solution, while CSP stations can be equipped with longer heat storage systems to generate electricity The cost is further reduced, which is also a key advantage of CSP technology.

ACWA Business Development Executive Director Andrea Lovato said: “The current power generation cost of a photovoltaic system with a four-hour lithium-ion energy storage battery is about 10 cents/kWh, while the power generation cost of an energy storage CSP system is 14 cents/kWh. At the same time, the price of solar batteries is falling rapidly, which will affect the advantages of CSP technology in terms of energy storage. Therefore, the cost of energy storage CSP technology needs to be greatly reduced.”
