Honda Fuel Cell Concept with Home H2 Refueling

It doesn't come easy writes "Honda unveiled their next generation FCX fuel cell concept car, along with a home hydrogen generation filling station, at the Tokyo Motor Show this week. The car has a range of 350 miles (560 kms) using two separate 350 psi hydrogen storage tanks. The tanks use a newly-developed hydrogen absorption material that doubles their capacity without raising the required storage pressure and thus allows the concept vehicle to exceed the DOE's targeted driving range for hydrogen powered vehicles. The home refueling station uses natural gas to produce electricity, heat and hydrogen. Honda estimates that the HES system [will] lower by 50% the total running cost of household electricity, gas and vehicle fuel. As the FCX is a concept car, no mention of when the technology might be introduced in a real automobile or what it will eventually cost, but the advances demonstrated by the car are quite amazing."

So as far as the world's proven oil reserves are concerned, the future is pretty bleak. And this isn't even saying anything about the trillions of tons of CO2 we'd be dumping into the atmosphere.

      What about the environment? Trillions upon trillions of tons of toxic wastes will be generated from extraction of hard oil reserves. Even in-situ methods aren't clean. And then there's the tremendous amount of water needed to process this stuff.

      And last but not least, our old friend CO2. At 83.2% carbon and an average weight of 1 metric ton per 7.3 barrels, burning all that oil would add about 1 trillion metric tons of CO2, not including the CO2 that comes from everywhere else and our diminishing flora that reclaims it. That's enough to raise the CO2 content of our atmosphere (assuming a 100km cieling) by .24 kg/m^3. The density of air at sea level is 1.2 kg/m^3, thus yielding an atmospheric content of about 20% CO2, or about the same as when the dinosaurs roamed the planet.

      At this point, I guess I don't even need to mention the other noxious gases that would constitue significant fractions of our atmosphere at that point. Eventually, the planet would recover after we die off, as it always recovers from such disasters.

      Even if we had trillions of barrels just ready for the taking, I'd push for renewable energy. Burning oil for the next 100 years or so is not only completely stupid, but also incredibly dangerous (from a human perspective, the planet could really care less).

    Ideally, a battery with enough capacity and efficiency would be best. Ultimately, I think some kind of direct electrical storage is going to power everything we own.

    But there's that capacity and efficiency issue... a lot of the power used to charge a battery is lost to heat, and not all the power "inside" the battery is usable. And batteries, per weight, can't store anywhere near the power gasoline can. (I use Power on purpose here, since it is not just an issue of energy storage, you have to be able to pull the energy out at a useful rate. I realize storage of power is not really a coherent concept.)

    Someone will probably link to real data on efficiencies and densities - I could be wrong on the energy density for newer (very expensive) battery technologies, but I suspect nothing is coming close to gasoline yet (neither does hydrogen).

    A big capacitor with no standing power drain would be perfect - high discharge rates, efficient charging, etc- but we don't have capacitors with the capacity or ability to hold charge forever while not in use. Some day, the entire hydrogen economy will be rendered obsolete by a better electrical storage device. Even then, there'll probably be a coal or deisel power plant somewhere, still generating the electricity we'll be storing in our portable supercapacitors.

    I'll just let him do the talking. This is an excerpt from October 10.

    The Federal government has loaned the oil companies crude from the Strategic Petroleum Reserve. The SPR contained 700 million barrels of crude when the hurricanes hit. The US uses 20 million barrels of oil a day, of which we produce altogether about seven million barrels ourselves. It is unclear how much oil is coming out of it now, but the last time a president tapped the SPR (Clinton) one million barrels a day were released.

    These actions have beaten down the price of crude oil on the various futures markets. At the same time, gasoline pump prices have leveled off from the refinery squeeze. I doubt that the motoring public is driving a whole lot less. The commutes haven't magically gotten any shorter out in Dallas and Denver over the past month. The national fleet of SUVs has not been changed out either.

    What's happening, therefore is that we have entered an eerie hiatus. Some band-aids have been applied to our oil and natural gas supply injuries and the bleeding seems to have stopped. But the truth is that our energy supplies are badly compromised and at the worst time of the year -- just as we slide into the home heating season. Here in the northeast, we have barely had to turn on the furnaces yet, but that will change in a week or two.

    In the background of this scene, the global oil production peak lurks -- meaning that there does not seem to be any surplus production capacity anywhere in the world, including OPEC's big gun, Saudi Arabia. So all we have here in America is a temporary appearance of normality. When the furnaces go on, the WalMart aisles will be empty. If there is any reduction in car trips, it will be because Americans are making fewer visits to the Big Box stores. There will also be fewer trips out to visit the model homes in the new subdivisions.

    Another unpleasant truth about the situation is that the US public wants to pretend that everything is okay as much as its leaders do. The public is not so much being misled as demanding that its leaders in government, business, and the news media continue a game of make-believe -- that we can still run a cheap oil economy without cheap oil.

    I see many people really don't understand Hydrogen fueled cars. Natural Gas is one of many sources used to produce Hydrogen but currently is the cheapest method to do so. It can also be made from petroleum, coal, various chemical reactions, and from biomass (landfill waste, wastewater sludge, and livestock waste). Solar and Wind can also be used to produce hydrogen.

    Now to address hydrogen safety for those who might worry about it.

      1. Hydrogen combusts at 550 degrees celsius. Gasoline will combust long before Hydrogen does.
      2. Hydrogen disperses rapidly because it is lighter. Ignition is unlikely.
      3. When Ignition takes place, It burns upward and quickly.
      4. And tanks that are used to store hydrogen have been subjected to firing .357 magnum at it, detonating a stick of dynamite next to it, and subjecting it to fire at 1500 degrees F.

    From Wikipedia Fuel cells are electrochemical devices, so they are not constrained by the maximum Carnot cycle efficiency as combustion engines are. Consequently, they can have very high efficiencies in converting chemical energy to electrical energy.

      can have very high efficiencies is very different from are much more efficient. I agree that they are not bound by Carnot, and in theory can have excellent efficiencies, but do they?

      A little searching tells me that the popular type of cell used in automotive applications is the PEM (Proton Exchange Membrane) type. These seem to peak out at just over 50% efficient. Not bad, but a well build IC engine can get into the upper 40's, so "much more efficient" becomes a point of contention.

      Then consider that the PEMFC's output is electricity, which must be put through a motor to drive the vehicle. If we're generous and assume the motor is 90% efficient, you are now on par with a well built ICE powered vehicle...

      This says nothing about the cost of the fuel. Even if you could "generate" the fuel yourself, the primary source of power is still fossil fuels. The only difference is the problem isn't in your back yard anymore. To add insult to injury, the best method to produce hydrogen (energy-in versus yield) is reforming of natural gas (methane) - as the home-refueling station in the article does. Guess what? You'd get more energy if you just burned the NG straight and you're still releasing CO2 into the atmosphere from the reforming process. At least they recover some energy for domestic hot water with their system, so it's not a total waste.

      So again, what data is there to back the claim that this is "much more efficient" than an ICE and that you get "more bang for your buck"?

      Well, when you're talking about total efficiencies, yah, it's probably comparable. But that's not quite the end of it.

      First, that 40% for an ICE is a maximum, and varies over the speed of a vehicle. That's not the same for an electric vehicle. So net, over a trip, you're going to get a solid boost. Yes - this argument falls apart when you talk about a hybrid vehicle. Sure.

      I don't know how a fuel cell's efficiency varies with temperature, though, and I know Li-Ions have strong temperature dependence on efficiency, so it might still even out.

      At least they recover some energy for domestic hot water with their system, so it's not a total waste.

      Domestic hot water and electricity. Now you get the advantage of avoiding all of the transmission losses.

      I do have a feeling that they probably did properly work out the total costs. They're only claiming a 50% total efficiency.

      Plus, as a side benefit, natural gas is a local resource, which means that effectively, the gas costs less because they're feeding money back to their own economy, as opposed to petroleum.

      Well, you already caught my response to that by noting that the wasted heat would be used, so it's probably a total gain overall. Recovering heating costs in the winter is fairly large, so that could make up the whole deal.

      Remember, they're only talking about a factor of 2 total savings in cost for heating+fuel+electricity. That's not a big gain, and for people who have hybrid cars, it's probably just breakeven.

      That being said, I doubt they took into consideration the fact that your refueling point is now your destination, so you don't need to waste fuel refueling. Minor, minor advantage, but still an advantage.

      The main advantage I see here is that it's an excellent stopgap until large scale hydrogen distribution is around. Natural gas distribution is already well established, so you're essentially leveraging an existing infrastructure to "take over" for petroleum until a hydrogen distribution infrastructure can be built.

      Build these, sell them to people, start selling hydrogen vehicles as well, then start building solar electrolysis plants near water sources, and start ramping up a hydrogen distribution system. It could work.

      And yes, solar electrolysis of hydrogen is incredibly inefficient, but you can probably help it become cost effective with tax breaks due to the fact that it's an entirely local production.

    Another dumb moderator on the loose! Damn I had points yesterday.

    Yes - we do need to focus on using less energy. The issue is that the North American natural gas supply peaked in 2001. We have already lost at least 1/3 of the Nitrogen fertilizer industry as a result.

    We can get hydrogen mind you from the coal gas method that was used around the turn of the century. Essentually we put some coal in a bucket - slap the lid on it - heat it up and inject steam at high pressure and temperature.

    We have decent amounts of coal for the present. We have a huge north american shortage of hydrogen with Suncor for instance presently spending billions to design and build hydrogen plants.

    This is for the production of liquid fuels from bitumin. Liquid fuels typically have 2 parts hydrogen for each atom of carbon - ie - they follow the parafin series C(n)H(2n+2). N=8 => octane.

    Bitumin comes in about 1:1 H:C and coal is about 0.6:1 depending on what grade.

    So the issue is that the hydrogen shortage is sort of going to make this uneconomical. That being said I think there is reason to believe that thermal cracking of water (steam electrolysis) has promise from solar or nuclear sources. Many people don't realise that the temperature of the photons from the sun is quite a lot higher than even the hottest nuclear power plants are run at.

    Nevertheless one would have to cover their house and out buildings with solar collectors and these would need to be a combination of thermal and electrical. There is some thought towards attaching a thermocouple to a solar cell which might bring the efficiencies up. Any way we look at it however its going to be prohibitably expensive to try to make your own source of hydrogen. It also might actually be dangerous because this is an industrial process and high temperatures and pressures are involved.

    Even a large parabolic mirror is dangerous because improperly set up it can light your place on fire.

    ----------------

    If anyone is interested check the BP statistical energy review. This will break down the various energy sources. Since most of the oil is used for transporation it follows that the hydrogen source will have to grow large enough to replace the oil. Currently the USA uses about 10 million barrels of oil per day.

    The energy bonds associated with carbon are greater than hydrogen so you need an INCREASE in the hydrogen if we manage to go with this system. However that is offset by greater efficiencies so perhaps it actually will take less hydrogen.

    This leaves Suncor for instance in a dilemma. They can produce the hydrogen and use it to upgrade the bitumin. Or they can produce the hydrogen and forget about their tar sands mines and put the hydrogen in a pipleline. Which is better? There is more hydrogen in a gallon of gasoline than in a gallon of liquid hydrogen and you don't need tanks capable if holding 350 atmospheres. The infrastructure from distribution is in place.

    The rain on the parade however is that more than a billion dollars per year are currently flowing into Alberta, Canada in an effort to ramp up tar sands to about 3.3 million barrels per day by 2015. Even with this massive investment the total synthetic crude that is going to be available is going to represent less than 1/5th of what North America burns today.

    If we couple this with the fact that world oil production is likely to be well past peak by even 2010 with a conservative (very conservative!) decline rate of say 3%, given that the world oil production is currently about 82 million barrels per day (with the USA burning 1/4 of the world's production) then just two years of decline will wipe out what the Tar Sands ops can make available.

    This means we are going to be facing a very severe energy problem in very short order.
