Motor emissions could have fallen by over 30% without SUV trend, report says - Lemmy NZ

Motor emissions could drop by 100% if we banned ICE vehicles already.
And entire world’s economy would drop by 100%. World is not ready to transition into EVs, and most likely will never be. In my opinion what Toyota is doing is the right approach. Higher quality ICE engine which can directly burn hydrogen. They already have the engine, just need to push it hard enough so R&D pays off. Hydrogen is expensive and hard to make (in terms of efficiency), but it’s infinitely more scalable than batteries, and cleaner too. But with higher popularity price will drop.
Latest figures are that green hydrogen accounts for 0.04 percent of total hydrogen production.
Because there’s no demand for it. Currently production is very dirty but the engine itself is green as it gets. As the demand shoots up government can and probably will stimulate green production of hyrdogen. Point is, once you have hydrogen car there’s no upgrade path needed anymore. Initial ICE engines were of poor efficiency but it got better. But we have to pick technology which can scale with demand. Batteries are simply not it, especially when it comes to big transporters like boats and trains. You can’t use batteries on those. Even trucks are problematic as battery weight significantly reduces amount of cargo.
