Truckers Choose Hydrogen Power 511

Posted by ScuttleMonkey
from the now-to-make-it-bite-sized dept.
hipernoico writes to tell us Wired News is reporting that hundreds of semi trucks now on the roads are being partially powered by hydrogen. From the article: "These 18-wheelers make hydrogen as they go, eliminating the need for high-pressure, cryogenic storage tanks or hydrogen filling stations, which, by the way, don't yet exist. These truckers aren't just do-gooders. They like Canadian Hydrogen Energy's Hydrogen Fuel Injection, or HFI, system because it lets them save fuel, get more horsepower and, as a bonus, cause less pollution."

      In either case the diesel is cutting into someones proffits and someone is eager to cut costs. Maybe the ends isn't a decrease in pollution, but it's a natural by product in using less fuel, which is a major goal for any semi-truck owner.

      You mean some cars physically disconnect the stator wheel from the crankshaft? I'm probably a bit rusty on my car mechanics, but as long as that thing is spinning you're generating electricty. That electricity has to be enough to cover the maximum current draw of the electrics system plus some headroom, so you're always generating more power than you need.

      Surely it's a No Brainer that putting the excess power back into the engine (electrolysis, hydrogen, blah blah) is Good Thing.
      • Surely it's a No Brainer that putting the excess power back into the engine (electrolysis, hydrogen, blah blah) is Good Thing.

        Yes, but the more current you draw, the more the alternator serves as a brake on the engine. You know all those "regenerative braking" hybrid systems? Same principle: they brake by dumping electricity from motors now running as generators back into the batteries.

        • Yeah, I wasn't going to get into that, but it would seem their idea allows them to obtain a higher overall efficiency, more than compensating for the added resistance on the engine.

          I'd think of it as distance 2nd cousing of the turbocharger and the nitrous injection, if you look at the common principles (though instead of burning more fuel per stroke, it burns cleaner fuel)
      • I'm probably a bit rusty on my car mechanics, but as long as that thing is spinning you're generating electricty

        Not necessarily. If you turned a generator and the poles weren't hooked up to any circuit, it's not moving any electrons through that circuit.

        Take a motor sometime and turn it with the leads disconnected. Then short the leads and try to turn it.
    • The addition of hydrogen causes the air/fuel mixture to combust a little hotter at a little faster rate. This allows for a more efficient burning of the fuel. An added bonus is that currently the "infefficiency" is being released through the tailpipe as black soot. The compounds that made the soot are now being burned, which is where the extra energy comes from. Well, that and the fuel being burned quicker means the mechanical energy released is able to be captured more efficicntly.

      RTA, the hydrogen helps the diesel combust more completely so you get more energy from each gallon. Some of that is lost in the water->hydrogen conversion, and some is a net savings.

      My question, though, is why not just produce the hydrogen at a plant and enrich the diesel with it at the refinery?

        Maybe the hydrogen would evaporate out too fast? It'd certainly float to the top of the fuel pretty fast, so you'd have to mix it constantly. Maybe you could suspend it in something solid, but then you have a new particulate matter in the fuel stream, that also has to burn fast enough to make the hydrogen useable...

They installed a hydrogen refilling station in Munich in '99(IIRC) and more are on the way, some in the US.

        In a word, yes. Although with a good catalytic, a hydrogen combustion engine has an exhaust cleaner than the ambient air in major downtown centers. So by running a hydrogen combustion engine, you're not only making no more pollution, you're cleaning pollution as you drive. Unlike fuel cell vehicles, which don't make anything worse, but don't make anything better, either, as they're not taking in any air and making it cleaner.

      The trick is that the hydrogen is not there to produce energy, but by burning hotter it improves the combustion of the diesel, so the efficiency improvements of the combustion out weigh the losses in the electrolysis system which is driven off the alternator.

      A very clever system, I hope whoever came up with it has a patent on it, I'm not a big fan of IP, but that sounds like a real invention.

    • What is the effect of burning the H2 on the burning of the diesel? Perhaps that is the missing part of the equation.
    • Based on the tests done with a Jeep Cherokee outfitted with the Canadian device, fuel economy increased by 40% and burn efficiency increased from somewhere around 30% to 97%. There were also no detectable CO emissions and the tailpipe remained cool after an hour drive. So therefore the amount of electricity required from the alternator to split the water is far outwieghed by the increase in burn efficiency.

      I would assume similar results are to be found in a diesel engine.

This has nothing to do with the hydrogen fuel debate.

    The effects of hydrogen injection sound similar to the effects from water injection, except that it may work better without additional engine tuning.

    Water injection (often mixed up to 50% with alcohol or methanol) has been used to improve the detonation resistance of combustion engines for many years. It was pioneered by WWII engineers looking to extract more power out of their engines during takeoff and landing, but now is typically only used by people modifying or racing their cars/trucks.

    In your typical combustion engine, maximum power is very often limited by a phenomenom call detonation, also called ping or knock. What happens is that during the compression stroke, the air/fuel mixture overheats and spontaneously combusts which results in a huge spike in combustion chamber pressure. If it is bad enough, it can break pistons or damage rod/crank bearings leading to engine failure.

    There are a number of ways to reduce the chance of detonation which primarily involve cooling temperatures in the combustion chamber. A very common way of doing this is to add extra fuel to the mixture, but obviously this is not efficient or clean.

    By injecting a small mist of water into the air/fuel mixture, the presence of water will help cool the mixture and prevent detonation, letting you lean out the engine to where maximum power is produced as well as adding additional timing advance and/or add boost (if running a turbo or supercharger).

    As a side effect, the water ends up "steam cleaning" your combustion chamber which keeps carbon deposits to a minimum and your engine running well.

    However, water injection does nothing unless your power output is detonation limited. In fact, if you inject water with no other changes, power output will go down a small amount.

    It sounds like hydrogen injection may improve power and combustion efficiency in all situations.

    Since the amount of hydrogen generated can't be that large, I imagine that using hydrogen injection in addition to water injection for heavy engine loads would be a great combination.

    Hmm, maybe I better patent that idea.

    Air normally contains (roughly) 78% Nitrogen, 21% Oxygen, 1% Argon, and trace amounts of a couple of dozen other molecules. This is increasing the amount of Oxygen and Hydrogen in the air entering the engine and conversely lowering the ratio of the Nitrogen, Argon and other (mostly nonvolatile) gases. This will naturally allow for a quicker, hotter, more complete burn that generates more power and less naughty parts like Nitrogen oxides and particulate matter.

    I would imagine that the additional Oxygen provides a large chunk of the benefits, rather than it just being attributed to the Hydrogen.

    They've actually invented a way to use some handy prepackaged "air for burning" (distilled water) that is (relatively) efficient and simple to make by using electrolysis. Not too much of it, because there it can be too much of a good thing. Try running an engine off pure oxygen and see what you get. You'd still get explosions, but they'd likely be uncontained this time around. The amount of electricity to electrolyse a lot of water would be quite counter-productive anyway.

    I would imagine you could get much of the same results if you could figure out a way to filter some of the Nitrogen out of the incoming air. Unfortunately, there's no good, cheap, efficient way to do that... yet....

    If you go read the manufacturer's web site they don't claim that the introduction of hydrogen itself will increase the fuel efficiency, but that the hydrogen will clean out the carbon deposits in the engine.
    The process will take "from 0 to 9 months" depending on the type of vehicle, amount of build-up, the weather, the speeds driven, the idling time, start/stop driving, etc. Once the engine is cleaned you can see up to "40% increase in fuel efficiency".

    We're talking about some insanely small amounts of hydrogen here.

    The standard kit holds about 4 liters of water and will run for about 12,000KM. If 2/3 of the water is converted to H and captured for use, that means there's 2,261 liters of hydrogen extracted.

    I randomly took a Volvo VE D12 395 engine for specs:
    12.13L displacement and 1500RPM suggested cruise RPM, I'll guess 95Km/h is "cruise".

    12,000KM / 95KM/H = 124.3 hours
    Hydrogen is produced at 18 liters per hour
    124.3 hours * 1500RPM = 11,187,000 revolutions
    11,187,000 revolutions * 12.13L = 135,698,310 Liters of displaced air/fuel mixture

    If my conversions and guesses are close, that means there's .001% hydrogen to air ratio in the cylinders during combustion.

        A so-called "Diesel" engine works by compressing something until it heats up enough to ignite a bit of oxygen mixed in with it. You can use almost anything in a diesel engine as fuel, provided you adjust the compression appropriately. We use diesel because it's relatively cheap, for a hydrocarbon, and part of "relatively cheap" is "easily available near the highway".

        Diesel is essentially the same as the kerosene in your camp light, the fuel oil in your home heating unit, the jet fuel in the airplane you last rode in, and the solvent you might have cleaned your paint brushes in. And any one of them would light up just fine in a diesel or jet engine without modification, and it's hardly news that people do, from time to time, use alternate fuels in those engines when necessity arises.

        One fuel people sometimes use in Diesel engines is vegetable oil. It works fine, and essentially that's what BioDiesel is. It's neither particularly rare, difficult, or even new to use it provided you can find it. Farmers, mostly, have been users in the past, and it was not unheard of in the 1930's for the tractor to be running on corn oil or whatever the farmer had lots of and couldn't sell, or at least couldn't sell at a price that allowed him to buy an equivalent amount of diesel fuel from hydrocarbons.

        The question for BioDiesel is basically: do we have enough extra corn, cottonseed, canola, peanut, coconut, or [enter locally grown oilseed] to run our trucks and jet engines while still feeding ourselves, and de we eat enough fried chicken and french fries to use the waste oil to run all our trucks, buses, and airplanes. I tend to believe not, but I'm open to contrary evidence.

        f you are swayed by celebrities, I can tell you that there is a restaurant that gives it's used french-fry oil to Darryl Hannah, who uses it in her diesel engined vehicle. Kind of a wild child, that one, but hippies do some things right, occasionally.

    Truckers know how more than anyone from being financially pressured to drive fuel-efficiently. For example, next time you're in a traffic jam, watch how trucks wait about five stop-and-go-5-feets the other cars do, and they idle at a constant speed equivilant to that. Hills. Wind tricks. Pee bags.

    My point is that if it's economically ripe, the truckers will be the first to use a new form of energy. If they ain't using it, it ain't ripe (unless it's an amphetamine). Moreover, "If you got it, a truck brought it."

    The generated hydrogen and oxygen, when injected into the intake, promote the combustion of diesel fuel. So the thermodynamic efficiency of the engine increases nonlinearly.

    On the downside, the alternator is now constantly loaded, which is an unusual situation and does require additional power.

    Apparently the increase in overall combustion efficiency from the addition of H2 and O2 more than offsets the additional power requirement for the electrolysis. So in the end the engine is more efficient and saves money. Cleaner combustion should also lengthen engine lifespan.

    It should be possible to do the same thing easily with most automobile engines. The only problem I see is ensuring that the alternator is not overloaded, which is primarily a function of the electrolysis electrode size.

    This should also make automobiles easier to start, something useful in wintertime in high-altitude regions such as California where CARB gasoline is a requirement (and is a poor starting fuel).

    At the same time, all of these things sound like a scam. I have heard all of the arguments, some make sense, some don't. So, instead of arguing about it, why don't we slashdotters construct our own, test it out, then see what is real? First off, start by googling hydro-boost [google.com]. One of the first few links will take you to this page [angelfire.com], which is a complete set of "plans" on how to build this kind of device from parts picked up at Home Depot (or the building supply place of your choice/location) and AutoZone or Checker (or whatever auto parts store is near you).

    These devices are simple - they make what is known as Brown's Gas [google.com] - a HIGHLY EXPLOSIVE MIXTURE of hydrogen and oxygen gases (note that if you build a "hydro-boost" cell for your car, that you want to make sure all of the gas is going into your engine, and not building up in areas under the hood/bonnet - unless you want a "car that goes BOOM!" literally) - used industrially for welding (similar to an oxy-acetylene torch system) - in fact, from that google search link you will find many suppliers of industrial Brown's Gas welding systems.

    I don't know if these systems are the equivalent of fuel-line magnets or if they really work. If you are willing, try it yourself. Also note that I am not sure how your local environmental testing spot will treat you if you leave that device hooked up under your hood for a smog/emmissions test. They would probably fail you outright for unlawful engine modifications. However, they probably wouldn't have a problem helping you test such a system if you are willing to pay the fees needed - to see if emmissions go down if nothing else (other measurements they may or may not be willing to help out on). Just don't go through there "on the sly" - they don't look kindly on loose hoses, never mind funky emmisions modifications they don't approve...
