Significantly lower raw material costs and more affordable battery technologies are driving investments in the Asia-Pacific region's battery energy storage system (BESS) market.
Will EV storage reduce battery cost in China?
Mass EV production is driving battery cost reduction. By 2030, EV storage can significantly facilitate high VRE integration in China. EV storage will be more cost effective than stationary storage in the long term. Repurposing retired batteries shows diminishing cost competitiveness. EV storage will not be significantly reduced by car sharing.
Will EV storage be reduced by car sharing?
EV storage will not be significantly reduced by car sharing. With the growth of Electric Vehicles (EVs) in China, the mass production of EV batteries will not only drive down the costs of energy storage, but also increase the uptake of EVs. Together, this provides the means by which energy storage can be implemented in a cost-efficient way.
Can EV storage be a cost-efficient energy system?
To realize a future with high VRE penetration, policymakers and planners need knowledge of the role of EV storage in the energy system and how EV storage can be implemented in a cost-efficient way. This paper has investigated the future potential of EV storage and its application pathways in China.
Why do we need EV storage?
EV storage needs to address complex issues related to intra-day storage demand resulting from the high penetration of variable renewable energy, and tends to facilitate a distributed energy system where end-users can support each other instead of purely relying on the main grid.
Which EV storage pathway is most cost-efficient?
Currently, RB offers the most cost-efficient way of storage among three EV storage pathways, but both V2G and BS show larger potential cost reduction. This is because the fast reduction of EV battery costs and the limited cost reduction potential of RB.
Can EVs achieve large scale energy storage?
A potential capacity and cost comparison is conducted for each pathway, and it is concluded that EVs can achieve large scale energy storage effectively addressing the issue of intra-day power imbalance caused by the high penetration of variable renewable energy.
