Electric car batteries will have a life time that will make the car obsolete fast. The value of an electric car will diminish to about 10 percent of the purchase price after 5 years. The batteries will cost about $10,000.00 to $11,000.00 and could need replacing as quick as 8 years. Then what do you do with the old batteries. I have heard that lithium ion batteries could be a safety hazard if they crack open and get wet. No guarantee on this but I would like a definite answer from someone who really knows and not a battery salesman. What will work for right now is Natural Gas. What the future is will probably be is Hydrogen. When Hydrogen comes out solid and the prices fall we will be using a non polluting fuel that is totally renewable do to the fact that Hydrogen is the most common element on earth. What is the government waiting for?

MetroManiac: "urban_dweller. my statement stands.."
I disagree, your statement doesn't "stand", it's fallen flat.
1) Oil is a fungible commodity openly traded on several markets around the world. Rare earths are not.
2) OPEC controls roughly 40 percent of oil produced, while China controls 97 percent. Big difference.
3) Canada is the largest supplier of oil to the US. No threat in the foreseeable future of any reluctance on Canada's part to continue providing that oil. China's intent is to cut off all exports.
There are other differences between the rare earths commodities and oil, but the above should be enough to demonstrate the irrelevance of your statement.

My congratulations, fullauto, yours was the first post in 3 pages that brought up the fact that several rare earths are required to manufacture the high-temp magnets that must be used in EV motors. Guess who produces over 97 percent of the world's rare earths, has drastically restricted the export of these rare earths for the 2nd half of 2010, and has announced a 100 percent BAN on exports by 2012? That's right, it's China. They intend to use their resource to produce EV's for their own populace.
Any comment, MetroManiac?

SVMike, you are wrong! Hydrogen can be produced from any thermal source of 800C or more including concentrated solar or even nuclear power using the SI (Sulfur Iodine) process. Its conversion efficiency is over 60% while electric generators from NG rarely get that high. Sure you can use combined cycle which is a gas turbine with the waste heat in the exhaust boiling water into high pressure steam turning turbines connected to generators. However the same can be done with the gases from the SI process (hydrogen, oxygen and steam) upping its efficiency to 70% or so. When combined by LiFePO4s charge efficiency of 90% and distribution losses even NG combined cycle power gets below 50% overall (that is still much higher than the net 15-20% from an IC engine though).
Thus conversion of water to hydrogen isn't as inefficient as you claimed unless you are thinking of the net efficiency in creating Liquid Hydrogen or very high pressure gas storage (>=700bar). The first can be boosted, by combining the fuel cell with a heat engine like a Stirling or turbine with the liquid hydrogen being the cold sink (helium would be a good gas in the loop) and the second can have the energy of compression recovered mostly by a turbine or multi-expansion piston engine.
The reason for the battery in fuel cell cars is not for the long term energy storage or startup times because most PEM fuel cells are instant on and act like fully charged batteries with very slow leakage (the bigger the fuel source the longer for it to leak away). No its because of the low power of cheap fuel cells. They are great for long term sustained runs like the sustainer engine in the Chevy Volt EV. The batteries are there for their high peak power (10-30C is typical and only 1-2KWH is needed which is enough to accelerate the vehicle to over 100MPH or climb a steep grade and for their ability to store recovered kinetic energy during braking and long downgrades at the high rates typically encountered (100% of the kinetic energy of a 2 ton vehicle at 60MPH is 200WH (0.2KWH) during a typical 0.8g stop has a peak power of 416KW).
Now SOFCs do take some time to warm up (operating temperatures are from 200-400C) and they are used typically when the hydrogen has sulfur impurities usually from NG burning steam reformers as they are immune to their debilitating effects. PEMs choke quickly on such impurities. Hydrogen from hydrolysis or thermal decomposition (even from the SI process) don't have sulfur impurities. SOFCs can be more efficient than PEM based FCs, if they are in an insulated container with a heat exchanger between intake air and steam outputs.
The use of hydrogen and borax to make sodium borohydride is quite efficient and borax is cheap. It is a fairly good hydrogen storage material as 23% hydrogen is stored by weight and the energy density is 85% of gasoline. Given the high efficiency of PEM FCs, the net efficiency allows less volume to be used per 100 miles than an IC engine running gasoline. In fact PEM FCs can use sodium borohydride directly improving the efficiency from 52 to 55%. Its cousin, lithium borohydride although more expensive and more difficult to produce from lithium borohydroxide has 34% hydrogen by weight and 115% of the energy density of gasoline and the range usually will be 2-3 times that of a gasoline powered IC given the high efficiencies of PEM FCs. Although a direct conversion PEM FC has much less lifetime than the sodium one so indirect conversion is typical. Either way tankage is both smaller and far less likely to explode in an accident than a gasoline tank would be for a given range. The only unusual things are is that the water produced by the FC is injected into the SBH tank (or a reaction tank nearby) and that the borax is heavier than SBH making the vehicle heavier as the fuel is used up. But that is ok, because the waste borax is recovered (typically during fueling at the station) and sent back to the SBH plant completing the fuel cycle.

You've been fooled by the supposed cleanness of hydrogen. First, hydrogen fuel cars need batteries because they will operate like a hybrid. It takes a long time to warm up a fuel cell (several minutes) so you need the battery to provide energy for the first few minutes...or you can just sit in your car for 5 minutes wasting the fuel cell output while it ramps up.
Second, hydrogen needs a lot of energy to produce it. It comes from natural gas in its cheapest form. Or via electrolysis where you only get back about 20% of the energy put in which makes it much more expensive (as a fuel) than an EV with batteries.

These kinds of calculations are never simple and the article does not say exactly how they were made. When they say Lithium-Ion is better than gas they mean in terms of what? air pollution? land pollution? human labor? land use? For example it says that using hydrolectric energy for Li-Ion improves its number by 40%. Does that include the environmental impact of massive destruction of forest area that will occur from creation or reservoirs? Does it include the cost of human displacement such as has happened in the three gorges dam and loss of economic livelihood for all the displaced people? Never fall for simplistic arguments right away.

I partially agree with djgunrunner - we also need to build up the Hydrogen Fuel Cell infrastructure and come up with green ways of producing it.
I believe Lithium is part of the trillion dollars of minerals that have been discovered in Afghanistan.
Think of replacing the batteries in an EV/Hybrid the same way you think of all of the parts of your current gas burning engine: oil changes, filters, battery, alternator, spark plugs, ignition system, and the engine and transmission.
They all have to be rebuilt or replaced, eventually.

They continue to pour money hand over fist into Electric vehicles. They have no range. The batteries will cause the trade in value of the cars to go down because they will have to be replaced at what, 10 or 11 grand. This list can really go on for quite a while. Then you have to dispose of them. Now take Hydrogen. You know the option that has the least support. No pollution. Can be produced on the site where it is sold. No transportation problem or pollution. Does not affect food prices. Totally renewable. More bang for the buck due to high octane. Does our country support it? Does our nations alleged leaders really want to cut pollution or do they just want to talk about it?
