To be flippant, no kidding, that isn't surprising. Maybe we can power our cars off the energy spent talking past eachother over EVs the past decade.
The design goal of an EV is less emissions at the tailpipe, and to eventually be propelled by renewable electricity depending on your local grid.
The benefits of that are cleaner city air, and eventually lower carbon emissions from the generation of the energy that propels them. A current downside to that is the minerals used to make the batteries are costly to get.
EVs are one option forward, hydrogen ICE might be cool too. Neither is perfect yet, but they both have promising futures to be more sustainable than petrol/diesel.
Mining itself is an industry currently undergoing more electrification, which will bring down the carbon emissions of mining those minerals. Hydrogen from renewable energy is also possible, it just isn't cost effective versus fossil fuel derrived hydrogen while we still externalize the impact of fossil fuels.
- theshrike79 4y agoHydrogen ICE is a pipe dream. BMW tried it in the early 2000's and failed. Toyota is prototyping it without much fanfare. (Their current test car, a tiny Yaris can do two laps of the test rink before refueling and maintenance). All cars in the future will be propelled by electric motors. The only thing we're arguing is how are they going to transport the energy. Batteries? Hydrogen fuel cell? Some kind of generator, running biogas or 100% synthetic fuel? Most likely all of the above, depending on the use-case.

- theshrike79 4y agoWAY too many "Hydrogen is Coming Soon(tm)" people actually believe that a Hydrogen car is a regular ICE car with all the cool sounds, but you just fuel it with hydrogen and water comes out of the tailpipe. It's easy for them to reason that way, because that would bring the smallest change to their world. They can just use their normal cars that make normal sounds and refuel them at their regular gas stations. But the car would be more environmentally friendly. While in reality a HCV is just a normal electric car with a part of its battery replaced by pressurised hydrogen tanks and a fuel cell.
