The BMW Hydrogen 7 features a bi-fuel motor which can burn either liquid hydrogen or gasoline. The hydrogen pump is slightly more daunting.  (Source: BMW)
The U.S. really could have the hydrogen economy, it just might take 50 years.

If there's one thing many Americans agree on, it's that the nation is far too dependent on foreign resources. If you can't get behind that, there's also the environmentalist angle: burning fossils fuels makes us icky. Both ideas are becoming very motivational, but maybe not as much so as the constant flux and steady rise of gasoline prices. You hit our pocketbooks; we start to think about what's going wrong.

Between the various camps, just about everyone has started to realize that it's time to figure out a new way to derive power – especially for vehicles. Non-commercial vehicles account for 44 percent of the oil used in the United States yearly. They also contribute 20 percent or more of the carbon dioxide pollution produced nationally. Alternative energy sources for transportation alone could put a huge dent in national oil consumption.

The government has even jumped into the pool now, having mandated an investigation by the National Research Council on how we can get out of this seemingly endless black hole of oil dependence and price gouging. The NRC's conclusion? Hydrogen could do it for us. Only it may take half a lifetime to accomplish – not something environmentalists and economists want to hear.

There are several problems with building a hydrogen economy. First, there is the lack of infrastructure. How does the hydrogen get to consumers? Second, hydrogen isn't exactly inexpensive to produce as needed for hydrogen fuel cells. And since it involves using some amount of energy from some process, it's likely being made by using “dirty” power somewhere. Third, the general technology involved in hydrogen production and vehicles is not yet comparable to gasoline and internal combustion vehicles as far as cost versus performance is concerned.

On the subject of the latter, the NRC report states that though with continued development the total hydrogen fleet might reach two million vehicles, nationally, by 2020, it wouldn't be until approximately 2023 that the technologies could compete on equal footing, economically. The government would need to invest approximately $55 billion over the next 15 years, expecting private investments of approximately $145 billion in the same time frame, to push the evolving technology to that level. While those seem like big numbers, they estimated that the yearly subsidy for ethanol fuels could reach as much as $15 billion per year in that time. Two minutes with a pencil and paper can tell you which of these will cost less in the long run.

After the new H vehicles become cost efficient, the NRC says, their population would likely explode. By 2050 there could be as many as 200 million, replacing a large portion of ICE-powered jalopies, thus cutting a noticeable swathe through oil dependency and pollution rates.

Unfortunately, the report, titled “Transition to Alternative Transportation Technologies: A Focus on Hydrogen,” is a best-case scenario. They also include that the best way to go about making the H economy a reality is not simply by snubbing oil and its dark miasma, but by encouraging other forms of alternative energy and a continued push for gasoline fuel efficiency while hydrogen technologies advance.

Overall, the future of hydrogen looks bright. Though the infrastructure will be costly to implement, it seems to suffer less of a poor reputation than other alternative fuels like biodiesel, which is being blamed for various economical woes like the rising price of meats, grains and dairy products. Every other day a new advance in fuel cell construction or efficiency surfaces and the media is thick with hoopla about fuel cell vehicles from various manufacturers. The only real problem the U.S. might really have if it were to make a concentrated effort to convert to the cleaner economy is a lack of patience.

we still need energy

Hydrogen only acts as an energy carrier. It takes more energy to create the hydrogen than it carries. Also, we need an infrastructure that rivals that of current gasoline distribution, which will be quite costly. This doesn't sound like the best idea to me. Perhaps the money that would be spent on such a plan could be used for researching ultracapacitors. These would allow for rapid charging of electric cars. Considering the electric infrastructure is already in place, this solves one of the problems facing hydrogen as a fuel. That being said, energy would still be required to supply to the electric grid. The best bet is nuclear as it produces the most energy with the least environmental impact, although new alternative energy sources can be used as well. The more energy produced, the better.

I for one think the work out there being done to convert cellulose directly in to gasoline and diesel/jet fuel are the most promising technologies out there. No need for expensive or complex fuel cells, or expensive research on how to reduce the weight of hydrogen storage tanks for performance cars and all aircraft. No research needed to adapt engines to a new fuel. This is one rock that kills a bunch of birds. Sort of like wind turbines. :P

Also, no infrastructure worries. Whatever moves around our gasoline today can move around the gasoline of tomorrow.

That + nuclear = potential future.

Of course, until that technology is commercialized, it's as pie-in-the-sky as everything else -- except nuclear, which is here today.

You know nothing about what Environmentalists want.

Fuel made from plant cellulose could be ideal since the carbon released when the fuel is burned was originally taken out of the air by the growing plant. So it would be carbon neutral, no net increase in the carbon in the atmosphere.

It depends on how much energy is needed to turn the cellulose into fuel. This is why ethanol from corn is not a solution. Distilling the ethanol from the corn requires more energy going into the process than comes out in the form of ethanol. So using ethanol actually wastes energy, and is not carbon neutral.

Hydrogen is made up of hydrogen. There's no carbon in hydrogen. So if you burn it, it doesn't become CO2 which is fine by "environmentalists". It is a clean burn that produces water when hydrogen + oxygen combine.

Hydrogen is not a fossil fuel because it can turn water back into hydrogen an unlimited number of times.

The Green fookers can complain.

They are the ppl. wasting resources on complaining.

Greenpeace are also being sued for. causing a property crash somewhere from thier. "Look this is what will happen".

Id advise think about about sht. before you do anything that will impact others. Or face the consequences.

And leave us to Rant freely in here :).

I wonder if some sort of plant could be genetically engineered to give off hydrogen instead of oxygen?

Why take the time and effort to engineer a new type of plant (tho it would be epic) when we can use existing species of plants to produce all the oil we need. I agree that being at least carbon-neutral is important; but considering the amount of time, not to mention resources that new sources of energy (for transportation) are being estimated to take, our first goal should be getting that energy dependency away from foreign pocketbooks; and an extremely promising way to do that? Algae. Algae can be as much as 5000, thats right, 5000 times as efficient at producing producing usable fuel than corn. While, i must concede there would be adjustments that would have to be made; the difference between the level of transition in infrastructure between H, ethanol and algae oil makes the latter the laughably easy choice. As i stated above; being eco-aware is most certainly a priority; it simply seems more efficient to direct trillions and trillions of dollars into the united states before we start looking for funding towards more progressive forms of energy.
P.S. - what would we need to sacrafice in order to completely supply ourselves with algae oil? a portion of the Arizonian desert, and that, my friends, seems like a very unbalanced trade.

Great post aboutt algae..except that alcan can PRODUCE 10,000 TO 20,000 AS MUCH BIOFUEL AS CORN.. and do it in the area of Arizona's desert at a fraction of the cost of oil imports Research done by US Dept of Energy in mid-90s & continued at MIT

see & google it for more info--it's real & already commercially in use in South Africa (they bought MIT's plans)

I agree.
Thats why I think the Chevy Volt is a step in the right direction, but it only addresses the new car market.

There could be alot of money in selling a EV conversion kit (with an optional gas generator) for the most common cars on the road.

Hydrogen, you are just changing where the exhaust pipe is. Instead of on your car it's on the Hydrolysis plant.

I think you are right. And whats more this way the transformation is easy and cheap and it already started with hybrid cars on the market. People buy hybrid cars first because it has low consuption, then they will be able to charge them little for a shorter trips and when they find out how cheap it is to drive on a home plug electricity they switch altogether to it. Transition would be easy and cost efective this way.One more advantage of this solution is that consumers can use their own solar panels to charge their cars which is perfectly cheap and efective. And I believe its gonna happen this way soon. When car producers get as far as ultracapacitator then you can charge your car in matter of seconds at the traffic lights or on the parking spot.Yop

Still far less explosive than gasoline :P. That's why you can use gasoline directly in a combustion engine, but you have to convert hydrogen into electricity before it can be utilized.

I personally feel that it's about time we started looking at phasing out ICEs as a mainstream transportation solution. It's time to retire ICEs. They have their place, but not on this scale.

Supplemental Hydrogen
By walmartshopper on 7/22/2008 6:36:15 PM , Rating: 2
Hydrogen vehicles may have a ways to go, but for now there's always supplemental hydrogen. A small amount of hydrogen used as a gasoline or diesel supplement increases the efficiency of the burn, increases power, and significantly reduces emissions. I have installed cells in my truck and my wife's car that produce hydrogen on demand by electrolyzing water (technically it's Brown's gas, but it works the same). My tacoma went from 17 to 25mpg city, and my wife's camry went from 22 to 35mpg city. Both of our vehicles run smoother and quieter and have noticeably more power. Plus it was a fun and relatively cheap project. The cells paid for themselves within weeks. Many people on the net (who don't even understand how it works) are calling it a hoax, but I tried it anyway... and now I'm saving over 50% on gas and helping the environment at the same time.

Energy sustainability is not something that our country can achieve overnight. In the meantime, the viable option would be to invest in the infrastructure of Natural Gas, which is most practical, cost-efficient, and domestically abundant bridge to hydrogen.

98% of the Natural Gas used in the U.S. is produced in North America and according to the Environmental Protection Agency, reserves point to at least a 60-year supply.

The International Association of Natural Gas Vehciles (IANG), says that the use of Natural Gas Vehicles (NGVs) will facilitate energy security and diversity as it can be used either as compressed natural gas (CNG), liquefied natural gas (LNG) or even blended with hydrogen.
