China s home energy storage solutions

What is China's energy storage strategy?

Localities have reiterated the central government’s goal of developing an integrated format of “new energy + storage” (such as “solar + storage”), with a required energy storage allocation rate of between 10% and 20%. China has created an energy storage ecosystem with players throughout the supply chain.

What is China's energy storage capacity?

China’s energy storage capacity accounted for 22% of global installed capacity, reaching 46.1 GW in 2021 [ 5 ]. Of these, 39.8 GW is used in pumped-storage hydropower (PSH), which is the most widely used storage technology.

What is a home energy storage system?

A home energy storage system is an innovative system consisting of a battery that stores surplus electricity for later consumption. Often integrated with solar power systems, these batteries enable homeowners to store energy generated during the day for use at any time.

How much does energy storage cost in China?

New energy storage also faces high electricity costs, making these storage systems commercially unviable without subsidies. China’s winning bid price for lithium iron phosphate energy storage in 2022 was largely in the range of USD 0.17-0.24 per watt-hour (Wh).

Which energy storage technology is most widely used in China?

Of these, 39.8 GW is used in pumped-storage hydropower (PSH), which is the most widely used storage technology. The share of novel energy storage technologies represents only 12.5% of the total installed capacity in China, where electrochemical storage is the most technically viable technology, followed by fast-growing compressed-air storage.

How has China created an energy storage ecosystem?

China has created an energy storage ecosystem with players throughout the supply chain. The upstream players are mainly battery and raw materials manufacturers, with many benefitting from first-mover advantage. Chinese manufacturers have gained a substantial market in this domain.
