Hydrogen Fuel Station in Iceland 382

Posted by michael from the should-be-greenland-ha-ha-ha dept.
klang points to this blurb about Iceland opening a hydrogen refueling facility. While it isn't, as the blurb states, the world's first hydrogen station, it is notable because it produces the hydrogen onsite with electricity from geothermal energy and electrolysis, making it an almost perfectly clean energy source.

    I don't understand why creating water instead of carbon-monoxide is better for the environment. If we suddenly replaced all fossil fuel engines with hydrogen engines, we'd have the same problem: excess waste.

    How many tons of waste do we humans send into the air every year? Do we think that equivalent amount of water is better? Instead of air pollution and all of the problems associated with it, we'd have to worry about the oceans being diluted, excess humidity, or some damn thing we can't think of.

    I actually am not of the opinion that it's as bad as people think it is anyway. So talking about changing from one form of waste to another is just an unnecessary expense.
    • Excess water will not a big problem... same with excess nitrogen. On the other hand excess CO2 *is* a problem.

      Water is a very easily manageable even if you consider it as waste.

      Water vapor is not bad for the environment.
      70% of the planet's surface is after all covered with water.
      You can then take that same water vapor, cool it, store it, and use it to make more hydrogen.

      Usually you have a closed hydrogen cycle: water + electricity -> hydrogen + O2 -> water + heat. This is why I think of hydrogen as a storage rather than primary fuel source.

      The real wildcard though is the source of the electricity. In this case it is clean, geothermal energy, though it could be solar, wind, etc. If you used fossil fuels, you would have the same problem as we have today but worse because of poor efficiency of the hydrolysis process.

            I suspect there will be a wide variety of hydrogen sources, mostly involving an electrical source, generated by wind, hydropower, geothermal, etc. But the algea may be an important part too.

        There's a difference between generating energy from fossil fuels in cars v/s doing so in a large electric generation facility. It is lot more efficient and "clean" to do so in a large plant where you are not worried about weight of equipment, acceleration, necessity to function in a range of climate conditions, size of engine, etc.

      It's because CO2 is a greenhouse gas -- it raises the overall temp of the planet, which may cause havoc. H20 is not a greenhouse gas. Also, compute the average time for a carbon atom to be captured by a plant, then returned to the atmosphere -- it's about 5000 years. Do the same for a water molecule to go from atmosphere to river and back to atmosphere -- it's a few months. Thus the atmosphere is better equipped to shed excess water than excess C02 (it's called rain!).

        Water is the most siginificant and most abundant greenhouse gas. It is also one we have the least control over. We do have some control over CO2 and Methane, and so that has been the primary focus of greenhouse gas reduction planning - but were a mechanism found to control water vapor, we might not have to bother much with controlling carbon based greenhouse gases.

          The feedback loop for CO2 involves freshly exposed rock becoming carbonate and getting transported to the ocean by the process of erosion, where it eventually gets subducted into the mantle. Higher levels of CO2 (theoretically) increase weather activity and the rate of erosion. This takes place over geological time, h

      I'm trying to decide whether the parent is simply confused or a clever troll. It has enough things wrong with it that I suspect the latter. But just in case, I'll "reply not moderate" (although I'd like to know who modded this up to 4):

      - Burning fossil fuels produces carbon dioxide as the primary pollutant (on a global scale at least; locally smog etc. could be considered more important). This is carbon dioxide that was not previously in the atmosphere, since the carbon came from stores in the ground. In comparison, using renewable biomass for fuel, for example, adds no additional carbon to the atmosphere.

      - The system described here is closed cycle. Water goes in, hydrogen and oxygen come out; then when the hydrogen is burned it recombines with the oxygen to become water again. Diluting the oceans is impossible in this case (and rather ridiculous in the fossil fuel case; consider the volumes involved).

      - The biggest win is probably on the local scale I mentioned. I don't think working to eliminate smog is an "unnecessary expense". Unless you think changing from breathing smog to breathing water vapor is just from "one form of waste to another", in which case I'll take the water and you can have the smog.

      I'm personally open to debate about exactly how bad global climate change is. But it's dangerous and dishonest to hide behind bad science to resist progress.
    • I don't think you have to worry about "sudden" replacement. It would be a monumental achievement for the US to migrate 1% of its in-use fossil fuel engines to hydrogen within the next 10 years. And if you can't tell the difference between H2O and CO (along with other noxious baddies) coming out a tailpipe, methinks you're deprived of oxygen already...

      True, but that's still an improvement because then all the pollution control machinery can be made very large and very efficient. Compare that to the current situation where all the pollution-control equipment has to be small enough to fit in a car, and cheap enough that it doesn't significantly increase the price of the car.


      And when the fossil fuels start to run out, we'll find it much easier to switch over to (solar/wind/fusion/whatever) if we only need to upgrade a few dozen large hydrogen-generation plants, instead of 50 million separate automobile engines.

    The abundance of geothermal energy in Iceland is probably a large part of making this shift to hydrogen energy possible. They have an abundant source of clean electrical generation capacity, something that pretty much no other nation in the world comes close to. For years ore has been shipped all the way from Australia to Iceland for smelting because of the incredibly cheap electricity rates there - it takes a lot of energy to smelt bauxite (to create aluminum), so it turns out to be cheaper to transport the bulk ore thousands of miles by ship rather than smelt in Australia. Thanks to the abundant, cheap energy available in Iceland, hydrogen production should be no problem.

    Most places don't have access to the abundant geothermal energy that Iceland has access to, located on a spreading center as it is. Spreading centers (places where two plates are moving away from eachother, creating new crust) bring magma very close to the surface of the Earth, much closer than pretty much anywhere else (except volcanoes, but those are a little tricky to harness the thermal energy from). I can't think of a single place (dry place, that is) besides Iceland that sits right on top of an active spreading center, so they are in a pretty unique situation (sure, there are failed rifts in Africa, but those are not active. Also possibly failed rifting in the U.S., but again, not active)
    So unless you find a way to get energy from dozens to hundreds of kilometers underground, much deeper than we have ever even drilled, then we will have to be stuck with our few spots of high geothermal activity for producing energy in that way. Oh yeah, and depending on geothermal energy just delays the problem - the Earth is cooling, albeit very slowly.
