Plug Power has been imagining fuel cell vehicles since 1997, but they have yet to produce a commercially viable model except for niche purposes. High price golf cart, yeah. Cross country vehicle, not on the horizon. Engineering and cost are formidable obstacles.
I'd prefer gasoline over hydrogen except for one very important distinction: you can make your own hydrogen. Gasoline has to go through the regulatory channels that the Dims intentionally clog up to control us.
Solar is far from perfect. But if you live in the southern half of the U.S. it can be very useful in weaning you off of the energy sources the Dims over regulate. My solar gives me a lot of freedom to use energy at home with 80% of our power coming from our own solar. This means the Dims' stupid energy policies impact our budget only 20% as much. (At least directly. Obviously I still have indirect impacts such as when the cost to ship groceries to my local store goes up it always makes my grocery costs go up too.) The EV is an extension of the quasi energy independence by making all of our local driving 80% independent from the Dims' stupid energy costs.
When I charge my EV, most of the charging is free from solar. If it was a hybrid BEV / HEV, on the months between long trips when I charge it and the battery gets fully charged, any charge beyond that could run an electrolyzer to generate hydrogen. I don't have to do it every day. Just on days I have a lot of excess solar power with nothing else to use it for. Eventually the hydrogen storage would be enough to use on the next trip to get through long drives between charging stops. Or maybe if I wanted to go on a 400-mile round trip with no stops.
One thing hydrogen brings to the table is it adds extra miles without adding a lot of extra weight (like having a larger battery does). This is the case even if the hydrogen is stored in a solid membrane to make it a lot safer.
Another thing hydrogen does is simplify the car. One thing I don't like about current hybrids is they are two types of motors (one electric, one ICE) with two types of fuel systems, etc. All of that dual complexity IMHO means twice the chance of malfunction. But hydrogen cars are really EV's with a different power source (fuel cell instead of large battery). So a hybrid BEV / HEV means it's one motor type (electric motor) with two power sources: battery and hydrogen fuel cell. IMHO that would be less chance of malfunction, while it would give those of us in the south (good for solar) a chance to drive many miles independent of energy sources the Dims over regulate.
