Therefore, increasing the technology innovation level, as indicated by unit benefit coefficient, can promote energy storage technology investment. On the other hand, reducing the unit investment cost can mainly increase the investment opportunity value.
In a certain sense, this study reveals the research on the promotion mechanism of energy storage technology under incentive policies and provides a certain reference basis for local governments to formulate and improve energy storage policies.
A firm choosing to invest in energy storage technology is equivalent to executing the value of the investment option . In this study, the investment opportunity value of an energy storage technology is denoted by F (P), that is, the maximum expected net present value when a firm invests in an energy storage technology.
China's energy storage incentive policies are imperfect, and there are problems such as insufficient local policy implementation and lack of long-term mechanisms . Since the frequency and magnitude of future policy adjustments are not specified, it is impossible for energy storage technology investors to make appropriate investment decisions.
To promote the implementation of independent energy storage stations, it is necessary to further optimise the electricity market mechanism. segments and targets. Investor participation is beneficial for the development of the energy storage industry.
Based on the economic characteristics of various basic activities and their value-added contributions to different degrees in the whole value chain, this paper divides the value chain of China's energy storage industry into upstream, midstream and downstream.
