California Drivers Can Tank Up WIth Hydrogen

Country_hacker writes "News site TBO.com is reporting ChevronTexaco has opened a hydrogen fuel station in Chino, California, and has plans to open five more. Servicing three (or more) Hyundai SUVs, these prototype fueling stations are a part of a five-year cost-sharing program put on by the Department of Energy. Could this be the 'egg' in the alternate fuels 'chicken or egg?' scenario?"

    We've had hydrogen refueling in Washington, DC for months.

      I did some work (low-level, pressure and piping design stuff) on the trials in Vancouver for buses. This was at least 7 years ago. Our proposal didn't win. I don't remember DC as being a candidate, as it was Vancouver and Detroit at that time.

      I'd be interested in the refueling, is it from tube trailers or LH2 trailers?

      Liquid hydrogen always sounds scary, but this stuff is road transported every day via million dollar tankers. One of the big industrial gas manufacturers has a video (taken from a local TV station's collection) where a LH2 tanker overturned--nothing happened. Of course, safety and technical specialists from all over had to be called-in to placate the local authorities.

      When cold boxes are built (I know as I've designed a few), they are often stencilled on the exterior as CBOX1, PCB1 (pump cold box 1), et cetera. During shipping via Schnabel everyone wants to take a look and people worried/ignorant about technology have fits about possible nukular explosions.

    Here's the Chevron/Texaco fact sheet. It's just a demo site to fuel five experimental Hyundai SUVs, and it's located at a Hyundai R&D center.

    It makes its own hydrogen, though, from natural gas.

      I've read some articles that say corn-based ethanol is pretty much a scam to raise the demand for (and price of) corn. Apparently producing corn ethanol requires a shit ton of energy and fossil fuels. People are tripping over themselves to create "clean" and "renewable" energy, but they're losing sight of the big picture and the laws of physics.

      I'm not going to find a site because it's late.

    Just where do you think the hydrogen comes from? The cheapest way to get hydrogen is by cracking natural gas. So much for getting away from fossil fuels. Also, anyone who thinks that only water (vapor) comes out of the exhaust is wrong. That would be true if all that went into the engine were hydrogen and oxygen. Guess what? The air is 80% nitrogen. NOx formation can be a problem with hydrogen engines. The hydrogen itself also has properties that make for a bad fuel: it has such a low density that it is hard to carry much fuel and hydrogen can find the smallest holes to escape from that other gases would not.

    Sorry, but you're mistaken on America's commitment to Biodiesel. Your comment on Biodiesel giving American farms a reason to exist again is well heeded by the powers that be, who are sick of providing subsidies to farmers so they'll stop growing. For more info, go here.

    Actually, they've gone to some real trouble to make carbon-fiber-reinforced tanks that are *very* hard to bust. I've seen the test footage, and when they finally did manage to bust one (which was no mean feat), it slowly leaked the hydrogen out. What is more, when they ignited the leaking hydrogen, it just burned, Just Like Gasoline; it did not explode.

    Incidentally, leaking H2 is somewhat safer than leaking gasoline, because it tends to float up and away instead of accumulate in a growing pool on the ground.

    FIRST: you assume 10 percent efficiency, whereas average decent cells nowadays are more like 20 with good ones around 30

    NEXT you assume only one square metre of solar cell space.... how big is your house? mine is around 8*20 metres = 160 m^2

    SO if you take my house as an example, you are looking at 160m^2 * 200w (say)per m^2 * 8 decent sunlight hours per day = about 250 KWhours per day IF i cover my entire roof with panels, plenty to power multiple cars and the house and the neighbours house etc etc.

    THE only problem with this scenario? due to a lack of widespread investment in solar technology, as opposed to oil or other fossil fuels, solar cells still cost about 5 bucks a watt, so your looking at an upfront investment of about 160 grand to cover my roof in panels. Now obviously i dont quite need that much power, but either way itll be a fair whack of money at current prices (otherwise i wouldve done it long ago). Hopefully some of the new thinner solar technologies coming out soon (within a year or two) will lower prices to a more reasonable level.

    CNG is available in the vast majority of service stations. It blew me away when I first got here - being an American, I had no idea it was in widespread use.

    Good points:
    - It's a lot cheaper than gasoline, about .40 AUD per liter vs. 1 AUD for gasoline (and Australia has some of the lower gas prices in the world)
    - A liter of CNG gets you (just about) as far as a liter of gasoline
    - It's less polluting

    Most of the Sydney-area taxis use CNG for precisely this reason. The one person I know who owns a CNG-fueled automobile for personal use has a brother-in-law who owns a taxi company, so he got a stock vehicle, and had it painted (Sydney taxis are white)... He loves it.
