https://a9w7k6q9.stackpathcdn.com/wpcms/wp-content/uploads/2023/03/An-Update-on-Chinas-EV-Revolution.pdf I have a new PPT online about China's EV revolution, which is now 2 years into a major, hockey-stick growth pattern few saw coming. I'll probably post the individual charts here later in the week.
55% of Chinese power is generated from coal, and 17% from Nuclear, Hydro and Renewables together. Are these cars contributing more or less to climate change than ICEV's?
@Pampa Because of the greater efficiency of EVs, each EV reduces emissions by roughly 50% compared to an ICE, on a per-km basis, after including upstream emissions from battery manufacturing, minerals mining, electricity, oil refining, and other factors. The benefits of EVs in China are even apparent in regions with the most coal. These benefits will grow as batteries get more efficient and as the RE share rises.
@Pampa Equally important are the air quality benefits, which was one of the original catalysts for EV adoption. While most of China's air quality problem comes from coal, the coal power sector is not a major culprit. Air quality modeling shows a significant air quality benefit for urban areas adopting EVs, while the increased coal emissions are negligeable.
Given how we extract Lithium from the ground to provide components for EV batteries, and the damage this also causes. Should we also start more discussions around Hydrogen Vehicles (lets call them HVs) so we can look at multiple solutions. I am sure hydrogen can be extracted far more easily then Lithium and is easier to do so.
Esp if we use solar panels to power the electricity, which then gets hydrogen from water or powers other extraction techniques to extract from the air for example.
@zleap @Pampa There are also better and easier solutions for the lithium problem. Batteries are getting more efficient, lasting longer, and recycling will start to scale up. More environmentally sound extraction methods are on the way, though these depend on price and regulations. Perhaps what happened on cobalt will happen on lithium, though it’ll take years to know.
@zleap @Pampa As the IEA notes, first and best use of hydrogen is in substituting for fossil fuel-derived hydrogen, then for making addition ammonia and methanol. After that come potential uses in marine and aviation. It is unlikely that RE-derived H2 will be available in sufficient quantities to meet these demands. Beyond these applications, the poor efficiency of FCVs is devastating for both their economics and carbon abatement potential. https://www.nature.com/articles/s41928-021-00706-6 https://www.nature.com/articles/s41558-021-01032-7.epdf?sharing_token=WNMrraktjyxydmZ37t5XrtRgN0jAjWel9jnR3ZoTv0NvvcjgkZX46JlO7Nfw7zfyvoADBvTOq9WIfhdmgV2dg_Zm-ooRIvDUajySVOgslfK-wkOrhQeaskxdoHd9CQkDKrEyWaG7Nek-etV6-wjBn0LukVZpsV7ZIbuxiMdSO6Q%3D
