Nanoparticles Could Make Hydrogen Cheaper Than Gasoline
Roland Piquepaille writes "According to EE Times, a California-based company called QuantumSphere has developed nanoparticles that could make hydrogen cheaper than gasoline. The company says its reactive catalytic nanoparticle coatings can boost the efficiency of electrolysis (the technique that generates hydrogen from water) to 85% today, exceeding the Department of Energy's goal for 2010 by 10%. The company says its process could be improved to reach an efficiency of 96% in a few years. The most interesting part of the story is that the existing gas stations would not need to be modified to distribute hydrogen. With these nanoparticle coatings, car owners could make their own hydrogen, either in their garage or even when driving."
What do you think the odds are on getting some of this stuff for my hydrogen car kit?

I already make my own combustible gas while I drive. I just need a motor that will work with it.
-- What you do today will cost you a day of your life.
So I can make hydrogen while driving. At an efficiency of perhaps 96%. So, 100 units of energy in resulting in 96 units of energy in the form of hydrogen. Those 96 units then pwoer the car.
Why wouldn't I cut the middle step out and simply use 100% of the energy to make the wheels go round and round?

As someone pointed out in the comments on the last hydrogen story, the problem isn't so much making the stuff as it is storing it. Hydrogen cars are a pain because it's incredibly difficult to store hydrogen in such a way that it doesn't leak out. They mention in TFA that this process is so efficient that cars could do the electrolysis on the go with a tank of distilled water, but unless it's efficient enough to be self sustaining that won't work.

I can't decide whether using bottled water as a fuel source would end up making it more expensive, or less. On one hand, someone would try to make even more money off it...but on the other, it's already the most ludicrously priced product out there.
disclaimer: yes, I know bottle water isn't distilled...or even filtered, often.
Excellent--now everyone will have tanks of hydrogen gas in their homes.
Is there some way I can invest in firehouses?
Hydrogen is a method for transmission and storage of energy. It is not a source of energy. At least not until they figure out controlled fusion.
Here's a two sentence summary for the people who don't read articles:
Instead of using a really good conductor to make the electrodes used for electrolysis, these people propose increasing the electrode's surface area 8,000 times by coating an ordinary steel electrode with butt loads of nanoparticles that are optimized for surface area and conductivity.
That sounds feasible to me.

Let us know when someone actually develops something real and working, then it might be news. TFA says it is working, and at 85% efficiency. They speculate that by 2010 they could get up to 96% efficiency. Also TFA says they partnered with one of the major battery manufacturers and will be releasing a product later this year that uses their technology.

Everybody giggling about this would mean the end of "Big Oil" forgets that gasoline is only one of many petroleum based products. Plastics are still going to be a huge market, for example. The oil companies still won't like it, as their profits will no doubt go down. On the plus side, the profits for terrorist funders (Saudi Arabia) would go down, too.

You're just simply... nuts.
"Big oil" are energy companies. They really don't give a rats ass if they sell you oil or nuclear fusion. "You" arn't even their real customer, but rather the power plants are.
Any sufficiently advanced technology is indistinguishable from a rigged demo.
The article says "Our nanoparticle-coated electrodes make electrolysers efficient enough to provide hydrogen on demand from a tank of distilled water in your car."
That's a completely baffling statement to me. So baffling as to trigger my BS detector.
Presumably the point of producing it in the car is to avoid the need to store the gaseous hydrogen. But electrolysing hydrogen requires energy--the hydrogen is not a source of energy so much as it is a storage medium for energy. So where would that energy come from?
From a gasoline-powered generator in your car? Or what?
Sounds like a smooth-talking snake-oil salesman who's answer to everything is "yes, we've solved that problem too."
"How to Do Nothing," kids activities, back in print!
Dude, do you need everything spelled out? Just start your car, drive around, and after a while you'll generate enough hydrogen to start your car.
No to speak for any of those companies, but if this or other technologies are as good as they claimed to be and if Exxon/Shell/big-oil buy the technology, why would they shelf it in the basement of their lawyer's office? These are just for-profit companies. As such, they don't really care what they sell. If shits can power cars better/cheaper than gasoline, they will sell the shits because they have a competitive advantages compared to others in their business. Why would they pay the Saudi emirates if they can just monopolize the production of energy at home?
The commentary on the original article, though, links to the the press release which clarifies it. The application they're talking about is a plug-in rechargable car. When you're at home, you plug it in, the car electrolyzes water to produce hydrogen, and then, when you unplug it, you run the car on the hydrogen.
The application, then, doesn't address the problem of how to store hydrogen, only the problem of how to produce it.

How about a self-sustaining crack pipe?
The article does not say anywhere that you can produce hydrogen while driving.
My mistake (last post. Read the article and not the summary)
The article says that Kevin Maloney says "Instead of switching 170,000 gas stations over to hydrogen, using our electrodes could enable consumers to make their own hydrogen, either in the garage or right on [sic] the vehicle,"
Doesn't say 'while driving' It implies that you can supply some sort of power source, presumably plugging the car into an outlet to run the fuelcell backwards and produce hydrogen.
There's some criticism as to the notion that hydrogen could be created right on board a moving vehicle represents perpetual motion. It doesn't. Those critics are just jumping to conclusions. The implication is that the coating supposedly improves electrolysis efficiency to such a degree that hydrogen could be created with a small enough on-board system on-demand. With today's elecrolyzers, to make enough hydrogen on-demand to run a vehicle, the hydrogen generation gear would be bigger than the vehicle, so efficiency improvement translates to size reduction which makes this approach plausible. The PEM fuel cell went through similar size reduction before it was ready for passenger vehicle use. Anyway, it means you would have to have a power supply such as a rechargeable battery to run the electrolyzer on. I did not take from the story that they were claiming a system where: 1) water + power in, 2)hydrogen out, 3) hydrogen in, 4) power out, repeat for a water-fueled system. It needs power.
Now, why would you want to do this instead of simply use the battery for electric drive? Well, one could make the argument that converting standard hyrdocarbon fuels from the pump to hydrogen ON the vehicle eliminates the need for fueling infrastructure change which is a MAJOR barrier to the widespread adoption of a "hydrogen economy". With hydrogen on the vehicle it could be used to power a fuel cell for electric drive or some other combustion engine such as BMW's multi-fuel hydrogen car. "Just add power" (solar? plug-in? other?) and if it's all done just right, what you get is more efficient fuel combustion with lower emissions than you would have gotten from burning the gasoline straight. That model I think could be viewed as a "stepping stone" towards conversion much like today's hybrid cars are regarded as a stepping stone towards all electric.
Everyone seems to have missed the point. With efficient electrolysis, you can build the entire system into the vehicle. You'd have a closed system that cracks the water and stores the H2 in a tank. The fuel cell burns the H2, creating pure water that goes back into the tank. You'd "fill up" at home (or office, or where ever) by running the electrolysis off of grid power (or however you get it), removing the need for the gas station. You could even use the power from regenerative breaking to crack the water again (assuming you could do it fast enough), meaning you wouldn't need to lug around extra batteries or ultra-capacitors.
Remember: you shouldn't think of hydrogen as a fuel, but rather as an energy storage mechanism (like a battery).
... to have the on board electrolyzer. You would have to think of the whole system as a rechargeable battery as opposed to immediately thinking of it as a perpetual motion machine. You plug your car in overnight, which generates the hydrogen for your next trip/commute. In the morning you unplug and have some hydrogen to go. You don't need a combustion engine, just your standard fuel cell + electric motor. I suppose you could add in a large solar panel roof to produce a little extra hydrogen on the go and when parked. By having it onboard you gain the ability to "charge" your car anywhere where there is power. /patent pending + copyrighted + .... + ???? :-b
last question first:

Sell it. Do you think the current C*0s, and board give a rats ass about 10 years down the line when they can make a billion or 3 right now?
How many companies sold key manufacturing technolgies to overseas buyers in exchange for a large chuck of cash now? A hell of a lot, that's who.
So, you own this magic widget. You can sell it for 1000 dollars 100's of millions of dollars. cha-ching, YOu RIGHT NOW make huge cash in your pocket. I don't think there so altruistic as to think "I could put a billion in my account, but we better not so some guy I don't know can makes some money in 5 years after I have left"
Not to mention the 15,000,000 new cars are bought in the US every year, and if you owned this you would be getting royalties from each of those cars for 20 years. So the company will still get some money, but the people making the decisions now get a hell of a lot of money.

I propose using ancient deposits of carbon to lock up excess O2. Not only will this process remove excess O2 from the atmosphere but the process if exothermic and could also be used as a source of energy. In the mean time I suggest breathing as hard as possible at all times.
Personally I look forward to an oxygen rich atmosphere and the return of our dragonfly overlords.

Not only do you avoid all the issues of converting vehicles --a very big issue indeed-- you can also invert the normal equation and actually consume atmospheric CO2 in the process.
How bout them apples? Not only would such a technique halt the addition of CO2 into the atmosphere from the burning of fossil fuels, it would actually begin to actively reduce CO2 levels.
The chemistry is old school.
CO2 + 3H2 --> CH3OH + H2O
CH3OH is methanol.
Using catalysts, which is this company's specialty, it is possible to convert methano into gasoline.

This way you change as little as possible on the consumer automotive side and yet still move to a post-pertroleum world without any new massive automotive technology roll out. That's a freakin' huge plus right there. A lot of people genuinely love their old cars. This way they can keep their old rides forever. As much as I love clean tech, I kind of have a love affair with my old car I've rebuilt so many times and there's a lot of people like that in this world. The easier we make it for everyone to participate, the faster the impact will happen. If you just go with gasoline, the switch can happen almost overnight.
If the hydrogen production process is really as efficient as they claim, it should be quite cheap on top of the environmental and political benefits. Moreover, you could install the production facilities very near existing gas tank farms located at the edges of large metro areas thus further maximizing efficiencies that petroleum can't hope to match be eliminating the need for extensive liquid fuels transport systems.
The CO2 could be produced through simple air compression. Local gasoline would once more be a reality.
Hydrogen cars really have nothing going for them. You can read the all the gruelling details here, but basically, li-ion batteries are about 99.9% efficient, while fuel cells are usually 40-50%. The tank to wheel efficiency of hydrogen fuel cell vehicles is ~35-40%. 85% electrolysis efficiency is nothing new; that's what big steam reformers get, although it would be new for small "kit" systems. Then there's transmission losses for getting the power to the elecytrolyser (~93% efficient) and power plant losses (~35% efficient for existing systems, 45%+ for next-generation). Put it all together and hydrogen is notably *worse* for the environment than gasoline, while electric cars are better for it. And they almost have the range of hydrogen cars, automotive li-ions (as opposed to laptop li-ions) -- nanophosphates, titanates, spinels, and so on -- are far safer than hydrogen (for many, many reasons). And they can recharge as fast as you can feed them juice to boot, and have almost the range of the best hydrogen cars, with no need for platinum at all, with next-gen batteries vastly outranging hydrogen. And on, and on. Hydrogen cars are a dead-end, environmentally destructive technology.
Clean energy sources like electricity? In half of the US, "electric cars" should be renamed "coal-powered cars".
Hydrogen is absolutely clean and the production has oxygen as a by-product. Electricity (and don't think that I am against electric power by no means, but let's be realistic) is generated using a still dirty process. Hydrogen, from production to burn, is much cleaner. That is not even taking into account the environmental footprint that production of electric cars produces. This (hydrogen cars) would not significantly change the footprint of existing vehicle production (this could be wrong, but it doesn't seem it would alter it that much) and reduce the emissions to 0. Electric cars significantly increase the vehicle production footprint to achieve the same thing. Over time both are better than current petroleum based vehicles, but which one is really the cleaner option?
Until we have dependable and cleaner electricity production, hydrogen cars will be the cleaner solution for the total life-cycle of the product and maybe even if electricity is cleaned up.
I agree with your overall conclusion that hydrogen cars are probably not going to happen, ever. Hydrogen is difficult to make, difficult to transport, difficult to dispense, difficult to store on vehicle, and difficult to utilize. We have not really solved any of these issues. And as you said, the only real advantage is that it burns clean (sort of, if you burn it in an ICE you will likely still have NOx issues).
Answer: They're not an OIL company, they're an ENERGY company. They understand this. If something else displaces oil they don't want it to displace THEM. Instead they want a piece of the new thing, too. They're just as happy to invest in developing and manufacturing solar panels and pocket some money when you buy them (or to run solar farms and sell electricity) as they are to invest it in exploring for oil and taking a cut when you buy that (while passing on the bulk to the people sitting on the land over the oil.) And meanwhile it gives them a power source to run some of their own remote equipment. B-)
There's a lot of money in oil. But there's little margin. Virtually all of it goes to pay for the crude feedstock and the infrastructure to extract, refine, and ship it. (That's OK. Like groceries, oil goes from purchased raw material to sold product in a short time. So the company's money gets cycled through the buy/refine/sell process several times a year, making a small profit margin add up to a good rate of return on investment.)
As with solar panels, energy companies have more incentive to develop new processes than to buy and sit on them. Because they won't be the ONLY processes to achieve results. So if company A buys process a to develop product whiz-bang, then sits on it, company B eats their lunch when it buys and develops process b and owns the market as whiz-bang displaces refined oil.

You say that companies would sell the wonder widgets now and screw all for the future, but nothing in corporate history really supports. You're using the percieved fallacy that companies only care about the immediate revenue. That's very true if your name is "Middle-class-Bob" but when it comes to product they stick with the same thing for as long as possible and really only desire to kill competition. Them buying such a technology and hiding it or ruining/discrediting the people making it are far more likely to occur than them selling. Do you really need to look any further than your mp3 collection and the numerous RIAA articles to see how much industry leadership resists change? Speaking of long term, car companies, fast food, and wal-mart all started their market conquests with the idea to not have the best product, service, or technology, but rather to make sure there tech and product was the only one that mattered.
Lubricants can be done effectively without oil these days, most of the companies that sell motor oil provide at least one line of synthetic oil.
You misunderstand the meaning of "synthetic" oils. They are synthetic in that they are lab-created from stock ingredients to specific and precise formulations, rather than refined directly from crude oil as in a "traditional" oil. That said, the base stock chemicals still come from petroleum, such as an alkene, an ester, or the newer gas-to-liquid where a light-chain gas fraction is separated, hydrated and catalyticaly converted into a desired liquid.
The advantages of synthetic oils are that you can pretty much completely eliminate undesirable compounds, and you can precisely tailor chemical ratios to achieve a desired behavior. Neither of those are possible/feasible with distillation, since a "bad" compound might have a boiling point within a hair-fraction of a degree of something "good", and a lot of different "good-for-different-purposes" chemicals have very close boiling points as well.
You are right about plastics being relatively easy to make from non-petroleum carbon sources -IIRC the first plastic was made from cellulose- but there are many types of plastic that can't be made with something that simple/natural, and don't even get me started on the problems of using corn for bio-fuels and carbon stock. There are better plants, but that's what you get for letting Iowa choose the presidential candidates.

For the retailer, perhaps; a friend owns a gas station and told me they make 1-3 cents per gallon. That's a razor-thin margin of 0.3% to 1%, at current prices.
However, there's a ton of margin for the oil companies. Just look at their record profits for 2007 to tell the real story: yes, the price is going up due to conflicts and reduction in supply and other factors; but their profitability tells a different story, and profits tend to tell a real story (except in unsustainable cases like Enron).
I think eliminating subsidies to the oil companies is a smart move; I read today that the House is passing it, and Democrats are trying to avoid a filibuster in the senate. Only for the top 5 oil companies, though; I'd rather see all oil subsidies eliminated, in favor of "renewable energy" subsidies (it's not really renewable, the sun will burn out someday and take the Earth with it we recently re-learned, but it's "essentially renewable").
I feel fantastic, and I'm still alive.
