On January 19, 2016, the World Energy Agency said that the cost of battery energy storage will fall by 70% over the next 15 years as new solar cell technology and other technological advances drive prices down.
Energy storage itself is not an emerging technology, but from an industrial perspective, it has just emerged and is in its infancy. China has not reached the level that the United States and Japan treat energy storage as an independent industry and issue special support policies. Especially in the absence of a payment mechanism for energy storage, the commercialization model of the energy storage industry has not yet taken shape.
