Summary: With the increasing electrification of road transport in China, there is a need to put eyes on the disposal of retired batteries. Reusing the retired batteries for rural electrification presents great promise, but this possibility has not been comprehensively investigated. We study how to contribute to sustainable development goals and carbon neutrality in China by establishing a battery-reusing system in rural residential sector from 2021 to 2060. Our results show that, before 2060, the accumulated rural residential installations of distributed solar photovoltaics with reused batteries can reach 364.2∼403.0 GW. The avoided annual CO2 emissions range from 505.9 to 536.4 million tons, and the total recovered lithium and cobalt from retired batteries will be no less than 88.8% and 60.0% of their respective 2021 global mining volumes. The system is believed to introduce changes to subsidy-driven policy to promote sustainable development by transitioning to one that is market based. Science for society: With increasing electrification of road transport in China, there will be rapid growth in the volume of retired electric vehicle batteries. However, effective systems of collection, recycling, and reuse of retired batteries are lacking. Meanwhile, the removal of subsidies on distributed solar photovoltaics (DSPVs) will slow down its deployment in China’s rural residential sectors. We study how to contribute to sustainable development goals and carbon neutrality in China by establishing a battery-reusing system through matching retired batteries to the deployment of DSPV in rural residential sector from 2021 to 2060. Results show that, before 2060, the accumulated rural residential installations of DSPV with reused batteries can reach 364.2∼403.0 GW, and the avoided annual CO2 emissions range from 505.9 to 536.4 million tons. The solution can be an important lever for China to decarbonize and potentially contributes to multiple sustainable development goals. |
