The global stationary energy storage sector is still quite immature, and China is no exception. Global installed capacity of stationary energy storage was around 3 gigawatts at the end of 2016, a fraction of the nearly 250 gigawatts of solar and 500 gigawatts of installed wind capacity.
Energy storage projects in North China are currently the most in China. Due to the geographical environment, the power grid in Northwest China cannot supply power to all regions. Provide electricity to the people of the region through off-grid distributed generation and energy storage systems.
Energy storage is frequently mentioned in China’s national energy policy documents and plans, but no explicit subsidies or support policies for energy storage deployment have yet been released. Most of the policy focus to date has been on encouraging continued technological innovation.
Increase the use of energy storage applications as part of a more comprehensive strategy to optimize China’s power system, including by improving the overall stability of the electricity grid. Too often there is insufficient learning from demonstration projects applied to larger scale deployment mechanisms.
China’s electric power system in particular can benefit from regulatory reforms designed to encourage energy storage development. The new focus on energy storage in China seems to be driven primarily by recent challenges in renewable energy integration, including the substantial curtailment of wind and solar power.
Even though several reviews of energy storage technologies have been published, there are still some gaps that need to be filled, including: a) the development of energy storage in China; b) role of energy storage in different application scenarios of the power system; c) analysis and discussion on the business model of energy storage in China.
