Lithium-ion batteries and CO2 emissions
How great are the CO2 emissions of South Australia’s world’s biggest lithium ion battery?
Master Resource recently published an article:
Are Electric Vehicles ‘CO2 Friendly’? (Swedish study raises questions)
It contains these facts:
“Based on calculations using the Swedish study’s various battery CO2 emissions estimates, as well as the methodology described by the EPA, I estimate that the carbon emissions sinkhole would equal between three and 5.4 years of driving an ICE car.”
“The Swedish study showed substantial CO2 emissions coming from the manufacture of the EV batteries. Importantly, the volume of pollution rises in a linear relationship with battery size, a trend driven by EV manufacturers working to extend their EVs’ range to ease consumer “range anxiety” concerns.”
“What the study concluded was that there were 150-200 kilograms (330-440 pounds) of CO2 emissions for every kilo-watt hour of battery storage. “
An important question the study addressed was the pollution related to the scaling of EV batteries. The data shows that pollution increased directly with battery size.
