      In fact, the Rocky Mountain Institute (who has been playing with Fuel Cells for more then a decade), says that Hydrogen is about as dangerous as Propane.

      Specifically:


      Tests conducted at the College of Engineering at Miami University aimed to find this out. 3000 cubic feet per minute of hydrogen was leaked from a vehicle tank and set alight. Over the course of the burn, temperature sensors inside the vehicle did not measure a raise of more than 1 or 2 degrees centigrade anywhere inside the vehicle. The temperature of the surface of the outside of the vehicle did not climb above that of a vehicle sitting in the sunshine!

      This might sound unintuitive. But when a carbon-based fuel like gasoline burns, glowing hot soot particles transfer the heat to its surroundings--potentially including you. But because hydrogen contains no carbon, it burns cleanly without a residue of hot soot, producing little radiant energy. This means that a victim would have to be practically in the flame in order to get burned.

If you have a basement, it will all settle there. It will remain there just waiting for the right spark to come along, at which time *BOOM*.

It has to mix with air before it becomes dangerous, even then it burns so quickly that you would have to compress it into just the wrong size room to cause problems. But hey we already have bottles of propane, butane, LPG, etc. They in my opinion are more dangerous, because they are heavier then air, which means they burn around you, hydrogen flashes above you.

    Hydrogen is also relativly easy to detect electronically in the air, so monitoring isn't a problem. If necessary add the good aweful smelling gas they put into natural gas.

    Batteries have to be recharged between uses. New gas can be added to a running system. Oh but so can batteries be recharged by diesel, or swap in new batteries. This is the same problem.

    Generators need more fuel, fuel cells need more fuel, batteries need to be replaced. Which one is more convienant to keep running, depends on how long you need it to run, the availability of fuel, maintainence costs (generators need to be serviced), how long you expect to run on backup power, floor space.

    b) Convieniance: Batteries recharge automatically, but you have to manually change the fuel cannisters. Quite true for this design. However this problems goes away with natural gas powered fuel cells (Same deal as electricity). Reversible fuel cells are also under development.

Looking at the hydrogen canisters they currently have available, they are industrial-size jobs, several feet tall, filled with H2 gas at 2000 psi, and can provide hours of power. These types of cylinders are pretty dangerous no matter what is stored in them. I work at my university's physics department helium/nitrogen facility, and I'd consider the pressurized helium gas cylinders at room temp to be far more dangerous than the liquid nitrogen and liquid helium we also vend, because a damaged 2000 psi gas cylinder is essentially a 150 lb. steel missile. Still, if properly handled and stored, they aren't too much of a worry. The types of customers who would use the AirGen in its current state are the types who probably have some high-pressure cylinders of various gases in use at the worksite anyway- the hydrogen cylinders are certainly no more dangerous than the oxygen canisters used all the time in oxyacetylene welding.

If it is as good as it sounds, it's a major step towards solving the fuel storage problems that have held fuel cells back for so long. Unfortunately, they don't give much in the way of specs- I'd be very interested to know how much uptime that 15 lb. canister produces in comparison to the pressurized cylinders, and what the uptime/price ratio is.

I can see why people are interested.) I'd also like to know more about the metal hydride it uses- lithium, or is it something else, like nickel or palladium? Storing hydrogen as a metal hydride is a good way to make it a lot safer and more convenient, but most metal hydrides are still extraordinarily reactive- I can remember all the reactions from organic chemistry that used lithium aluminum hydride to carry out heavy-duty reductions. Eschewing the huge steel cylinder/bomb to provide hydrogen fuel is a great idea, but I'd rather not have to keep a Type D fire extinguisher handy near my computer.

As more competition comes about and the public will learn of their benefits, I expect to see more of these little wonders, making more power at cheaper prices.


    Think of the benefits.
    A more powerful version could be built into new homes that would automatically kick in and provide silent, backup power for the refrigerator and freezer, to keep food from spoiling.

    This could possibly kick off the infrastructure necessary for having hydrogen based vehicles replace the current internal combustion engine powered vehicles of today.

    It could finally allay the public's fears about hydrogen being a volatile, explosive gas.

    Increased competition and development to make smaller, more powerful hydro generators will also translate into cars. A 1000 mile range hydro powered car that goes 0-60 in 4 secs with comfortable seating for four, yet puts out almost no pollutants could be in our future if these things were to be seriously adopted by society.

  81. That's a different technology by mkweise · · Score: 2, Informative

    That article is about about phosphoric acid fuel cells. That is a mature technology that's been in commercial use for over a decade. It runs at a high temperature, does not scale well below a quarter megawatt and takes time to start up. They compete with gas turbines.

    PEM fuel cells are just beginning to appear in commercial products. They cost more per kilowatt, but can be scaled down to the size of a laptop battery and can go from zero to full power in a fraction of a second. They compete with batteries and small internal combustion engines, mainly in mobile applications.

  82. Re:Continuing the hydrogen is highly flammable deb by DaChesserCat · · Score: 1

    For a detailed exposition on why the Hindenburg burned (not exploded), look here. I find it amusing that the term "Hindenburg effect" is used to describe the mindset that people have about hydrogen being dangerous.

    Also, the fact that the canisters are using Metal Hydride storage is rather nice, too. Lower pressure, but heavy, and much safer. Some of the newer metal hydride materials can store the same volume of hydrogen (in low-pressure, gaseous form chemically bound to metal powder) as liquid hydrogen (without needing to mess with cryogenic materials). Ovonics recently announced a material which could store more than 7% hydrogen by weight; this means that a liter container of their metal hydride could contains about 72-73 grams of hydrogen (a liter of liquid hydrogen contains about 71 grams).

    Roger Billings (currently with the International Academy of Science) who drove a hydrogen powered Cadillac in President Carter's inaugural parade (gives you an idea of WHEN), did some research on safety and metal hydride. He took some metal hydride containers, fully charged with hydrogen, to a US Army test range and had them shoot the containers with incendiary bullets. They punctured the container, and they got a "pilot light"-type flame which burned for a couple hours, but there was never a "burst" or anything remotely resembling a fireball or explosion. Safer than a tankfull of gasoline.

    The flame is invisible so if the tank is on fire, it may not be obvious. When they were setting up for the first Hydrogen bomb test, they had to vent some hydrogen for some reason or another. They lit the escaping gas and all they could sense was the noise from the flame - they couldn't see it. Unfortunately, neither could the few seagulls who flew directly over the flame and fell dead at the physcist's feet. I hear roasted seagull isn't very tasty.
