From the perspective of global energy storage development and application, foreign countries mainly cultivate the development environment of the energy storage market by improving the market mechanism and investing in fiscal and taxation support.
The construction of a new power system is not only the need for green and low-carbon development of energy and the realization of the dual-carbon goal, but also the need for high-quality development of energy system construction, and the historical process will be unstoppable.
It can be expected that the development of the energy storage industry will continue to develop, but the road of development will not be smooth. In addition to policies, standards, and technologies themselves, international industrial policy mechanisms and the stability of the global industrial chain supply chain are also crucial. Strengthen technical research and technical reserves, improve the innovation chain around the industrial chain, and stabilize the industrial chain around the innovation chain, so as to better respond to various risk challenges and market opportunities that may emerge.
