As much as I cannot stand
@AOC and her liberal drivel, in this instance, I agree with her. Hydrogen-powered cars are the future. They're 100% clean.
-
-
Yeah, okay ... smarty pants. But they are clean, in of themselves. No emissions other than water and oxygen.
-
What powers the electrolysis to separate the hydrogen and oxygen from water??? At the moment, mostly fossil fuels. You might as well burn them directly inside the engine.
-
They’re more efficient to burn at modern power plants. Also, grid power tech is decided on nearly a per plant basis, so grid level incremental and major changes are pretty easy to make and efficiency improvements are instantly transmitted to electric motor driven vehicles
-
That would take data to demonstrate. My intuition tells me the direct kinetic impact of gasoline explosion on a piston transmitted mechanically to the wheels is most efficient. Transmission lines, batteries and electric motors lose a lot.
-
Recent data strongly suggests this is true: https://blog.ucsusa.org/dave-reichmuth/new-data-show-electric-vehicles-continue-to-get-cleaner … - this takes into account emissions from the entire production cycle. There are other analysis that show similar results.
-
To be clear, I mean that the data strongly contradicts your intuitions and suggests that EV’s are more efficient on nearly any energy mix.
-
Thanks for the data. That's why measuring is important because intuition is not always correct.
-
Sure. More data and study is certainly desired, but it looks strong so far. MIT has a relavent study worth ready as well.
