> In the renewables case they’re needed for transportation AND grid. Indeed. So? There are more and more vehicles, and the average amount of electricity they store (reflected by their autonomy) grows. One of the reasons is well-known: https://ourworldindata.org/battery-price-decline https://ourworldindata.org/battery-price-decline > no forward movement This isn't true, many experiments are running ( https://en.wikipedia.org/wiki/Vehicle-to-grid#Research https://en.wikipedia.org/wiki/Vehicle-to-grid#Research ) Even EDF, France's leader of the nuclear industry, field-experiments it: https://www.edf.fr/entreprises/transition-energetique/mobilite-electrique/v2g-vehicule-to-grid https://www.edf.fr/entreprises/transition-energetique/mobili...

The drawbacks section is pretty damming that this is unlikely to work: > JB Straubel, then chief technology officer of Tesla Inc, discounted V2G, claiming that battery wear outweighs economic benefit.[87] A 2017 study found decreasing capacity,[88][89] and a 2012 hybrid-EV study found minor benefit.[90] A 2015 study[91] found that economic analyses favorable to V2G failed to include many of the less obvious costs associated with its implementation. When these less obvious costs were included, the study reported that V2G was an economically inefficient solution.

  > Tesla ... didn't at the time (circa 2015) like V2G because it competed with its Powerwall project. This is a completely obsolete consideration: https://zecar.com/reviews/2024-tesla-model-y-bidirectional-charging-v2g-and-v2h https://zecar.com/reviews/2024-tesla-model-y-bidirectional-c... > decreasing capacity This is true. However this is to put in perspective with the financial impact: batteries are (from a technical viewpoint) more and more able to cope with this and charging during cheap electricity times then partially discharging when electricity is expensive will reduce the overall cost of the vehicle. > A 2015 study Obsolete.
