Toyota Announces Plans For Fuel Cell Car By 2015
puddingebola writes "Toyota has announced plans for a fuel cell powered car at the Tokyo Motor show. From the article, 'Satoshi Ogiso, the Toyota Motor Corp. executive in charge of fuel cells, said Wednesday the vehicle is not just for leasing to officials and celebrities but will be an everyday car for ordinary consumers, widely available at dealers. "Development is going very smoothly," he told The Associated Press on the sidelines of the Tokyo Motor Show. The car will go on sale in Japan in 2015 and within a year later in Europe and U.S."'"
I remember at least 2 years ago, Toyota had this plan. Hydrogen isn't as bad as people make it out to be. You just need special materials to work with. If you go steel, it just gets owned. So special materials are expensive in the short run until they're manufactured. Hydrogen itself is just made with electricity and water. It isn't much different than electric cars in that regard. The main difference is electric cars need expensive batteries. Hydrogen cars only need a pressurized tank. I think in the long run hydrogen cars can win out. Do go investing in hydrogen refilling stations just yet though like that electric car got ahead of the curve.
God spoke to me
Wake me up when this has a chance of actually being a viable product. I doubt they can create the thing for a reasonable (non-heavily-subsidized) cost. Given that we are STILL waiting for laptop fuel cells which have been perpetually "around the corner" since literally the Dawn of Slashdot, I'm not holding my breath.
And once you have the car, you need the Hydrogen. There are currently zero economic ways of creating the stuff. You can either crack it off of Hydrocarbons (and if you are going to do that, why not just burn the damn things in a conventional car?) Or you can electrolyze it. Which is tremendously energy-inefficient. And then you have to compress it for storage/transport/delivery, wasting even more energy.
Hydrogen cars make sense if we have bountiful free electricity. Until that happens, electric cars make more sense, and neither will seriously challenge the dominance of the ICE.
1. I think the hydrogen will come from dead puppies and kittens who were slaughtered for their hydrogen.
2. Absolutely! It'll be paid for by the Government and not cost us a penny!
3. Excellent point! All this water will have to go somewhere - i.e. eventually into the oceans! And God knows what will happen if we start dumping water into the oceans!
Amory Lovins sees fuel cell vehicles as being competitive well before 2050, so this is an interesting development. http://www.rmi.org/RFGraph-cost_reduction_potential_of_powertrains
But hydrogen is interesting. And finally some competition for Tesla - let's see, what happens to a hydrogen fuel cell when you hit debris on the road!
They are going to avoid that situation by putting the fuel cell on top of the roof. It'll be perfectly safe.
If you think I voted for Trump because of this post, you're wrong. I voted for Dr. Jill Stein of the Green Party. Again.
To me, why not just use a natural gas or propane fuel cell? It would save having to make hydrogen from CNG.
If the fuel cell could handle both CNG and LP gas, the technology for storing propane is fairly mature, so it would be useful, not just for keeping an electric car's batteries topped off, but for a UPS or emergency backup generator.
I read a lot of hype about hydrogen, but that is an expensive road, and I wonder if the gains from it are worth it compared to better electric grids and higher capacity batteries.
1) It doesn't matter if it has the "range of a regular gasoline car". Because you would have to drive like 500 miles to find a hydrogen refilling station!
2) Hydrogen is expensive... at least as much as gasoline in most of the US.
I am a researcher working in hydrogen & fuel cells, so I'll just spill the beans:
It does, but not so much. Storing H2 at 700 bar requires a hefty pressure tank. They are fairly safe but that doesn't make them lighter. That's why hydrogen is suited for larger vehicles (family wagon, SUVs, long-range trips, trucks etc.). Short range is better served by batteries.
If you have cheap electricity, then it's water. You electrolyse it at the station and do not need to ship hydrogen around or build a gas network. You can also reform natural gas, which is cheaper, but then you need to clean the hydrogen really well: requirements on purity are 99.99% hydrogen, and other components are very severely limited (e.g. sulphur down to 4 parts per billion). It is debatable whether the purity standard is really necessary, though, it may be unnecessarily strict.
Main reason not to use electricity directly, as in batteries: batteries are heavier, and if you want to double energy storage in a battery car you need to double the batteries (which is not going to double the range—the batteries are heavy too). If you want to double the energy storage in a hydrogen car, you only need to double the hydrogen storage, the fuel cell (the expensive part) is still the same. And hydrogen storage is not nearly as heavy as its battery equivalent, also factoring in that fuel-cell conversion is about 50% efficient.
As I said above, a good alternative is not to have the infrastructure, but to produce and compress hydrogen locally at the station. The idea is that even with all the losses (hydrogen production, compression, fuel cell) the system is still more efficient that oil (drilling, extraction, transport, refining to gasoline, transport, combustion engine). More importantly, hydrogen can be produced starting from anything: natural gas, oil, solar, you name it. Gasoline comes only from oil (or coal if you want to go Fischer-Tropsch, but that's not really efficient and has large emissions).
No, the quantities are minimal compared to the oceans. Any day you will have far more water passing through your shower than out of your exhaust. 100 km of travel in a fuel-cell Mercedes B-class (yes I drove it :-) produce about 9 kg (i.e. 9 liters) of water. Besides, that hydrogen was produced from water from the biosphere anyway, so no balance is disrupted.
Victims of 9/11: <3000. Traffic in the US: >30,000/y
All the comments about H2 efficiency and explosive risk completely miss the point. Hydrogen fuel cell vehicles have been feasible for years, there have been a few Honda Clarity and Mercedes B-Class FCVs driving round Southern California (which has the ONLY public refueling stations in the entire USA) for several years.
The problem is demand. If you care about the environment you plug in for your regular commute. You can can already buy a plug-in hybrid for half the price and lower running costs than these 2015 cars. As Volt owners gleefully report, most drivers travel for hundreds of miles recharging at home, but for long trips the car has the quick refueling of gasoline that's available everywhere.
There's a market of people who don't want any tailpipe emissions and can't plug in and regularly drive long distances and live near the handful of H2 stations and are willing to spend a lot of money on a new technology, but it's vanishingly small!
Eventually fossil fuels could be so expensive or restricted that H2 will be the range-extender we use for our plug-in vehicles, if ethanol from biomass doesn't work out. But that's a long way away. Meanwhile Toyota and Hyundai are very cagey about whether you can plug in their HFCVs; it seems the answer is No. Their cars have a battery and motor so plugging in is the cheapest way to drive the first few miles, and I think soon consumers will reject a motor-driven car that you can't plug in. The comparative reviews of the first HFCVs against 2015's plug-in hybrid cars will be brutal, and there will be dozens of "gotcha" pieces, wherein the brave reporter drives out of Southern California and gets stranded.
