See the subject of the thread for the bottom line answer, though things are never as simple as a one-liner. But I gave you my answer, and you didn’t want to accept it.
I also gave you the reasons why, but you wanted sources, so there’s the table. I really don’t use this table - it was just to give you the info you wanted. I could pick and choose data pieces, but that wouldn’t be fair either. Hydrogen *can* be cleaner, and actually is frequently. For someone who wanted to jump into the deep data, something I learned recently is that for those charging from the grid at night, the energy they are using is virtually all non-renewable (fossil). And I’m told that most of it is from fracked natural gas.(this is all California perspective - other areas use more coal on the grid) For those of you that are thinking that faced with this information, battery EV are not worth pushing any more (haha), I’ll say that you are still wrong. BOTH are still important, and needed. And that’s been my point from the beginning. - Mark Sent from my Fuel Cell powered iPhone > On Dec 23, 2018, at 5:21 PM, Peri Hartman via EV <ev@lists.evdl.org> wrote: > > Mark, > Thanks for posting this.
