Here are the simple facts:
- BEVs are currently ushering in the beginning of the end of sitting around waiting for your car to refuel except for the rare long trip.
- This change is already available to homeowners and those who have access to charging at work.
- As BEVs and PVs proliferate, there is clearly a requirement to store the energy from the PV panels in the BEVs DURING THE DAYTIME. Doing that will be, by far, the cheapest solution to the storage issue, even factoring in the cost of installation of daytime charging infrastructure.
H2 FCVs like the Toyota Mirai do not provide a path to a future in which transportation is powered by PV.
Except that they can and in some case are being powered by H2 produced by PV (currently, wind is more common). And as noted above, the percentage of car owners who have the option of home or even workplace charging is very limited, and will be for a long time given that most people don't live like the majority of Americans. That workplace charging is important to soak up excess PV is something we have no disagreement over, as I mentioned in my reply to GetOffYourGas. That there will also be times when BEVs alone will be unable to soak up all the excess as the shift to intermittent renewables continues, and some of it will need to be stored or used for other purposes (like making H2), is also the case.
You have continually made this argument "And as noted above, the percentage of car owners who have the option of home or even workplace charging is very limited, and will be for a long time given that most people don't live like the majority of Americans."
According to Energy dot.gov "Because residential charging is convenient and inexpensive, most plug-in electric vehicle (also known as electric cars or EVs) drivers do more than 80% of their charging at home."
Someone is right here. I think you have been using the argument that most people do not charge at home to further the failed hydrogen experiment that you are always plugging. If I am wrong educate me.
There's no conflict here, you are talking about two different things. You are confusing the percentage of existing PEV owners who can charge at home, compared to the percentage of total car owners who can do so. The former are a self-selected minority, made up of people who can take advantage of home charging. It's like a poll that says that people who like this sort of thing, say that this is the sort of thing they like. Naturally, most people who have bought PEVs do most of their charging at home, because most of the people who opted to buy one know that they can do so, and that advantage weighs large in their decision to buy one.
A large majority of the remaining ~99% of the world's car owners who haven't bought a PEV and who might consider one, don't have that option currently, so a PEV is a poor fit for them (barring convenient workplace or other charging). Isn't education fun? As to whether hydrogen is a failed experiment, it's still far too early to say.
