Future of Cars: Hydrogen Fuel Cells, Or Electric?
cartechboy writes: "Back in 2010, Toyota and Tesla teamed up to develop electric cars. That partnership gave us the RAV4 EV electric crossover, but it seems as though that will be the only vehicle we see from that deal. The partnership will soon expire and Toyota has no plans to renew it. Why? Because Toyota believes the future is in hydrogen fuel cell cars, not battery electric vehicles. We knew trouble was brewing when the RAV4 EV failed to set the world on fire when it came to the sales floor. Then Toyota and Honda announced plans to debut hydrogen fuel cell vehicles as early as next year. Add it all together and the writing was on the wall. Is Toyota right? Are hydrogen fuel cell cars the future, or is it missing the mark?"
It's much simpler.
When you travel across the country and you don't know what kind of service station you'lll find along the way, diesel always wins. No alternative fuel even comes close to the reliability and availability of diesel engines, and that's not changing anytime soon.
So many advantages to hydrogen. It automatically increases the fuel tax by leaking, and further by requiring active cooling to keep hydrogen contained. It's expensive to produce and transport, so it doesn't threaten oil companies with lower fuel costs. It's plentiful, so you can use tons of other fuels to separate water into hydrogen.

The reason the electric vehicles aren't taking of has a lot to do with price (although there is also a legitimate concern about range between charges). But the price is a major factor, especially in an economy where the middle class (the lion's share of all car purchases) continues to get squeezed every time we look the wrong way. Seriously, let's look at price -- even the Nissan Leaf and the Chevy Volt (plug-in hybrid) are $40,000 vehicles. And electric vehicles go up from there -- up to the Tesla Roadster in the six figure range. The average American doesn't even spent $30,000 on a car, so the price range of these new vehicles is still in the realm of the rich for toys and games. And to be honest, hydrogen fuel cell vehicles are going to be priced in that same $40,000 and up range as well, so we won't be seeing those in the mainstream anytime soon. Henry Ford had it right back in the early 20th century. If you want your product to be adopted in the mainstream, you need to pay your workers enough to afford the product to be worth owning. They haven't done that yet, and until they do, we won't be seeing electric of hydrogen fuel cells in mainstream life anytime soon.
Yes, they're[plug ins] cleaner than hybrids, but they still depend on electricity ...produced by dirty fossil fuels... hydrogen fuel cells are, for now, the greenest of many options,
Hydrogen has to be cracked from complex molecules using...wait for it...electricity, so no, fuel cells aren't any greener than plug-ins. I suppose one could argue about whether the manufacture of fuel cells causes less pollution than that of batteries, but I expect it's pretty much a wash. I think the economy and convenience of recharging at home trumps hydrogen's greater range and shorter refueling time, and eventually battery technology will narrow those gaps.
Never let a lack of data get in the way of a good rant.
In the long run a gas tank is going to become cheaper than a battery array, but in the short run, electric cars are there already.
So a hypothetical gas tank is hypothetically cheaper than an existing and very real battery? Curious argument you have there. How about we just plug in a hypothetical Mr. Fusion while we are at it? I frankly disagree with how you are framing the issue given the lack of cited evidence.
Hydrogen is refillable. Hydrogen stations only needs electric and water.
If you already are delivering the electricity, why not just put it into a battery and use it directly? (presuming the battery has sufficient energy density)
Electric will always have the advantage of regenerative braking though.
Electricity has a number of advantages. It is independent of the fuel source. Electricity can come from coal, oil, gas, nuclear, hydro, solar, wind etc. Electricity also is compatible with other types of motors. You can have a gas-electric hybrid, a diesel-electric hybrid, a fuel-cell-electric hybrid, etc. No other energy source can do that. We do not have the technology to use hydrogen directly (requires pressure and/or cooling tech beyond current economic practicality) and there is no near term likely prospect for a practical hydrogen based fuel.
Toyota made a decision that works within their existing car infrastructure. Think about it. The car will still have a fuel tank, and will still run an internal combustion engine.
There will be no "range anxiety" and you won't have to worry about replacing the entire battery pack after 3000 charge cycles.
They are going to have to start forcing gas stations to carry hydrogen as well, the way some places carry diesel and kerosene, but that's not *their* problem, is it?
The advantage to hydrogen is that they can still continue to make cars "as is" -- hell, they can even make hybrids too, a Hydrogen Electric Prius is sure to be in the future, without changing much about their existing factories.

Okay, first off hydrogen fuel cell cars are electric. They just don't use a conventional battery.
Second, hydrogen fuel cell cars are not remotely competitive. Batteries are better and they're terrible.
Electric is just marginally competitive with gas and even then only in certain circumstances.
Someone is boundless going to tell me something great about hydrogen... but the problem is that its logistically difficult to move around, it escapes from any vessel you put it in especially under pressure. And ultimately you have to get the gas by pouring electrical grid power into some sort of electrolysis machine. And where is the grid power coming from? About half of it is still coal. So... by all means... get your green car and accomplish nothing.
We need fewer of these flash in the pan solutions and more ACTUAL solutions.
We need municipal power storage. Something more reasonable then deep cycle batteries. There are some places that pump water from a reservoir to a higher one to store power and then run that water through a hydroelectric dam to recover it. So far the most scalable power storage system we know. But we don't have enough of those. We need to look at flow batteries.
Once we're storing renewable energy electric cars will ACTUALLY have an impact on carbon emissions. Until then... irrelevant.

There's still a lot of improvements that can be made to the good old internal combustion engine. Both batteries and fuel cells are much more expensive - they may come down (slowly), but the efficiency of combustion engines will keep going up, thus maintaining the gap.
