I love the battery passport idea (perhaps something where blockchain could actually be useful with regards to energy). EVs can't be an example where they seem greener and are thus leaned into when doing so improperly creates more problems than it solves. But with such systems in place, we can ensure the transition really does benefit all stakeholders, including the environment

I will call out the swindle of "green hydrogen" whenever I get a chance, so here's another chance:

"Its recent low-emissions technology statement forecast the cheapest way to produce it in the short-term might be to use gas or “coal gasification” with carbon capture and storage (CCS). It said production methods using renewable energy would become cheaper as demand grew."

Let me get this straight: we should help finance a multi-$trillion hydrogen infrastructure which oil companies can use to sell dirty hydrogen just for "the short term". They want us to believe they'll take all the carbon emitted during the refining process, and stuff it underground somewhere (CCS). Or maybe make hydrogen from clean, green, gasified coal for a while. 

Then one day they'll start making hydrogen using solar and wind energy, that no one will be able to tell from their brown kind. They'll lose money, but it will help fight climate change. Got it!

The material the battery is made from as well as the life of the battery is very important as is the recycling. Tesla leads the world in all of these areas. They now make cells with no Cobalt. The life of their batteries is over twice as long as any other cells. They recycle and reuse 98% of the material when the battery is used up. 

   Their battery lasts 20 years at 90% capacity . Mostly this is from the cooling system that is very active even when the car is not plugged in or running. The round cylinder shape lets them cool better. Other batteries with no cooling or very weak cooling fail and lose capacity 10 times faster than Tesla battery packs.

   I also see new designs with Solid State being the best. Those that have combined Ultra Capacitors have also done very well. There are many new improved designs and chemistry coming out each week. This is just the beginning of great battery storage systems.
