Energy storage plays an increasingly important role in the energy transition, which can effectively solve the problem of renewable energy volatility and make the use of renewable energy more stable and reliable. Therefore, energy storage is expected to become an important part of the development of renewable energy, but whether it will become the "next photovoltaic and wind power" still needs to consider a variety of factors.

First, compared with photovoltaic and wind power technologies, the commercial application of energy storage is still in a relatively early stage. Although energy storage has broad application prospects in the energy market and power grid, its business model, technical route, market demand and other aspects still need to be constantly improved and perfected to promote the further development and promotion of energy storage.

Secondly, compared with photovoltaic and wind power technologies, the investment cost of energy storage is higher, especially for large-scale energy storage projects. This is also one of the main challenges faced by energy storage in commercial applications. With the continuous development and maturity of energy storage, its cost will gradually reduce, which will further promote the application and promotion of energy storage.

In general, energy storage has a broad application prospect in the field of renewable energy, but its commercial application still needs time and investment. The development of energy storage in the future will depend on the comprehensive effect of technological innovation, market demand, policy support and other factors.
