  1. Must've gave you a green on. That sounds like it would hurt. Really bad.

  2. H2 technology is assumed the grid would make the H2 from electrolysis at the pumping station. The idea is electricity would be made from fission and hopefully fusion soon and other non-carbon energy. And the material used to create a H2 cell is less destructive to the environment less resources needed. Lithium and cobalt is very heavy duty in its procurement. Problem with both right now: safety. Lithium battery vehicles can have spontaneous thermal runaway, as well as any damage or crash can cause them, and lithium burns in water. H2 vehicles are... H2. Most explosive gas when combined with some O2 and N2. There are some testing that demonstrates a bullet that pokes a hole in the tank, that the H2 jets out quickly burning up. It's slow leaks of H2 where it can mix with atmospheric air and become dangerously explosive. There are fixes to both: Lithium batteries: Better batteries that don't require so much cobalt and lithium. H2: Even better fuel tanks that force jet H2 venting it quickly whiling burning it when it is compromised to avoid an explosive mix, and sensors that detect any leak. End balance: H2 will become better when LFTR fission and/or especially Tokamak fusion plants are available. The H2 stations will use the grid to produce the H2 at the refueling plant, and you could produce your H2 at home (safety issue again though). It then becomes cheaper and more environmentally protective: to produce the vehicles and to distribute and produce the H2. So ultimately H2 is better compared to 140 pounds of lithium and about the same amount in cobalt just for a 4 door sedan. H2 when considering the compression required still has a little bit more bang for the buck on driving distance vs electric cars. Hopefully though, we'll still get better batteries that eliminate or greatly reduce thermal runaway effects. And reduce the quantity of both materials, because the mining and refining of them is very polluting.... and those materials are actually rare... lithium is 5 times more rare than copper in earth's crust. This means the price of an electric vehicle will become to expensive for essentially everyone to buy... as both cobalt and lithium supply is used; both is actually already happening over the past decade. Ultimately: we need a high energy dense power systems like LFTR fission and/or ITER or Wendelstein 7x fusion power plants. It's the only way we generation enough energy that takes us off ever needing fossil fuels... as both fission and fusion power have orders of magnitude energy density than fossil fuels, just as fossil fuels have orders of magnitude more energy than solar or wind.
