German Automakers Working On Hydrogen Fuel Cell Tech (arstechnica.com) 121

Posted by Soulskill from the quick-everybody-reference-the-hindenburg dept.
An anonymous reader writes: For the past several years, Japan has been trying to encourage development of hydrogen fuel cell technology for cars. Now it seems some German manufacturers are getting interested as well. "Audi used last week's North American International Auto Show in Detroit to debut its h-tron Quattro fuel cell SUV concept, and the UK's Autocar is reporting that Mercedes-Benz has green-lit for production a fuel cell version of its GLC SUV." The Audi vehicle has a range of roughly 600km. BMW has been working on this problem too: "For quite a while, the company was experimenting with internal combustion engines that used H2 instead of the traditional hydrocarbon fuel. More recently, it showed us an i8 and 5 Series powered by fuel cells, although neither is set for production."

    What's wrong with these automakers? Haven't they figured out by now that hydrogen is a total waste of time and effort? They tried this silliness back in the 90s and it went nowhere. It's a terrible fuel. It doesn't occur in nature like oil, so you have to use electricity to generate it (like by hydrolysis of water), and it's horrible for storage and handling because it's such a lightweight gas, unlike gasoline and diesel which are relatively easily-handled liquids; you have to have a highly pressurized tank to hold it, and leakage is a problem because hydrogen molecules are so small, so you're not going to get great range, and you've got a highly pressurized tank of highly combustible gas in your vehicle, which is a really bad thing if you have a crash.

    The future is electric cars, not hydrogen, and the intermediate step is hybrids. Tesla has already proven EVs work great, and only need cheaper batteries to be practical for the commuting masses, and the Chevy Volt and Toyota Prius have proven that hybrids are practical now.

          • Not quite. The H2 tanks are hefty, no arguing that, but the energy density of 700 bar Type III tanks is already far higher than the best Li-Po battery.

            • Batteries don't need energy density that high. The conversion efficiency of H2 to torque isn't nearly as high as it is for battery-stored electricity in an induction motor.

      • Teslas can get 170 miles worth of charge in 30 minutes at their Superchargers. For people who take normal rest stops for meals and bathroom breaks, that's not a big problem. And with the huge range they have when fully charged, they have more than enough range for anyone who isn't doing a long road trip, meaning anyone who's a commuter or other normal car user can use them right now without worrying about range (then rent a gas car for road trips).

Keep in mind that 98% of all passenger vehicle trips are less than 100 miles. In fact, nearly all Tesla drivers comment on the lack of lost time due to having to go to charging stations weekly or more. Fcv HAVE to go to fueling stations. Always.

        The charge times are a factor, but mostly it's cost, cost, cost!

        Batteries are economically unsustainable: Li-ion batteries (the type with high energy density that you need in any battery vehicle) cost about 500 $/kWh. You can expect it to drop somewhat through the next decades, say to 300 in 2050, but they are already being mass-produced and unless a significant, revolutionary breakthrough happens, this technology has already delivered what it can.

        Hydrogen storage, instead, costs about 12 $/kWh, much cheape

        • Lol. Tesla and LG are already well below 200/kwh. In fact, gm claimed that lg was below 145/kwh and approaching tesla's costs. Tesla is thought to be below 125/kwh, and says that they will be well below 99/kwh by 2020. So not even close to your rant.
        • And the rest of your rant is way off again. First off, Tesla and LG are thought to have much higher cycles. It is already known that first gen Tesla batteries in roadster went to about 150k before hitting 85% capacity. Now MS has several cars with 125k and are still around 95% capacity. However, where will the fuel cell on fcv be by 100k miles? They will be in the trash because they have to be replaced every 50k miles or so. Then lets add the fact that 96% of all hydrogen in the world comes not from elect

      • Yes, they avoid the problems of batteries, but add the much worse problems with fuel cells and storing hydrogen. The charge time is quicker, but they are worse than batteries in most other ways.

    • The cheapest way to produce large amounts of hydrogen is by hydrocarbon fractionation This process starts with, wait for it, natural gas. It also produces CO2 which is a powerful greenhouse gas.

      • Yep. On top of that, you're using energy to create the hydrogen in the first place, then when you burn the hydrogen in a piston engine, you're limited to the Carnot efficiency, and again are wasting most of the energy as heat. So your overall system efficiency is going to be crap, even worse in fact than with gasoline.

        At least with electric cars, the biggest source of inefficiency is the power plant itself, but there you have flexibility as you can use any power source, whether it's shitty, nasty coal, nu

No, the biggest problem today with fuel cell is that they typically use something like platinum as a catalyst and there's physically not enough platinum in the world to convert the worlds vehicle fleet to fuel cell.

      • Also, hydrogen is an intermediate in the Haber process for producing ammonia for fertilizer. You are essentially burning food.

    • Only Rube Goldberg can build the necessary infrastructure for this. It is totally unreasonable, unless they're making flying cars for outer space.

    • so you have to use electricity to generate it (like by hydrolysis of water)

      Most hydrogen is made by steam reforming [wikipedia.org] of NG, not by electrolysis. Although, if people are going to recharge at home, then electrolysis of water is most likely the way to go.

      EVs work great, and only need cheaper batteries to be practical

      HFCs work great, and only need better fuel tanks to be practical.

      Maybe a trillion dollar industry can explore more than one option.

    • The hydrogen is absorbed in a medium, it's not just pressurized like air or nitrogen. So the overall pressure is lower and in the case of an accident it won't all come out at once Hollywood style. It's roughly about as dangerous as gasoline. Lithium batteries can fail spectacularly in accidents as well, doubly so in a fire.

      Ideally, the best fuel would be something with a high energy per volume, such as the Audi-made synthetic diesel (e-diesel) from CO2 in the air, or perhaps ethanol. Something that doesn't need anything more significant than a liquid storage tank, as opposed to what is needed for CNG, or even LP gas. Cars get into wrecks, and who knows what might puncture the gas tank, so having a complex system is nice, but if it takes out a city block if the vehicle using it gets rear-ended, it isn't workable.

      a) The amount of weight that the cars need to lug around comes down a lot with fuel cells.

      Probably not. You would probably need a variable compression engine to add in H2. CNG or LPG dual-fuel is a simpler retrofit, "all" you need is to add injectors and nozzles and program the computer to handle it, or add another computer. As the VAG smog fiasco demonstrates, you can have multiple sets of maps in the PCM, so it's no problem to switch to different maps for a different fuel. You would also need a PCM with enough injector driver outputs to run a second set of injectors, or some sort of switching
