Hydrogen cars are probably a dead end. Not enough benefit for the infrastructure costs required. I think the future options will be EV and synthetic gas. As batteries improve further, EV will have a lot of advantages. But it will only be available for those who have personal garages. For everyone else, it makes more sense to create gasoline instead of building an entirely new hydrogen infrastructure. There is already technology in early stages that can create gas from just electricity, water, and CO2 from the air. It seems refining that technology is a much better idea than trying to use hydrogen.
Disagree entirely. Despite the fact that batteries are getting worlds better there are big wins for the environment when we eventually implement a hydrogen infrastructure. Batteries are an evolutionary win while hydrogen will be a revolutionary win.
The first version requires biomass, which means it has all the disadvantages of current biofuels. But their next goal is to remove that requirement. If they succeed, then they will have a process that only needs power, water, and CO2.
It's early stage technology and investment is probably very small right now. Why wouldn't it be when oil is so cheap. But someday the oil fields will start running dry and peak oil will truly come. When oil hits $200, $300 per barrel, the demand for this kind of technology will be immense. EV sales will increase dramatically, but many will be unable to use EV due to lack of personal garages (even Supercharger times are not enough if thats the only way to charge. And only Tesla has access to that, what about Leaf, Bolt, etc?).
A brand new hydrogen infrastructure doesn't seem to fit anywhere in the future. It's too expensive and the benefits are marginal compared to gas (a lot of legacy infrastructure) or EV (an entirely new paradigm using existing electric infrastructure).
