Batteries help reduce emissions, but how do we reduce their emissions?
Summary
A new study from the University of Melbourne looked at the emissions caused by making lithium-ion batteries, which are important for electric vehicles and clean energy storage. The research found ways to lower these emissions by making batteries last longer, recycling more, and using fewer batteries overall.Key Facts
- Currently, battery production causes about 0.18% of global greenhouse gas emissions.
- Battery emissions could grow 10 times or more by 2050 if production keeps increasing.
- Improving battery manufacturing and recycling could cut the carbon footprint of making a battery by 34% by 2050.
- Making electric vehicle batteries last as long as the cars themselves could reduce battery production demand by 29%.
- Limiting the growth in average battery sizes for EVs could cut demand by 23%.
- Using ride-sharing and repurposing old batteries for energy storage could reduce demand by nearly 18%.
- Combined strategies could prevent 6 to 7.2 billion tons of CO2 emissions between 2024 and 2050.
- Battery production emissions are a small part of total global emissions, but reducing demand adds up to significant savings.
