  • Waymo arson in San Francisco sparks new debate on self-driving cars

    Jump

  • The solution is to eliminate self-driving cars and instead invest more in mass transit and walkable neighborhoods.

  • Dude, where’s my self-driving car? The many, many missed deadlines for a fully autonomous vehicular future.

    Jump

  • China is merging hundreds of small banks to fend off financial stress

    Jump

  • It could mirror the economic stagnation of Japan that begun in the 1990s. Very similar set of circumstances.

  • America Is Missing Out on the Best Electric Cars: Whatever kind of EV you might want, chances are China has it.

    Jump

  • You’re better off spending it on stuff like mass transit and the like. It won’t just all disappear at some point in the future.

  • America Is Missing Out on the Best Electric Cars: Whatever kind of EV you might want, chances are China has it.

  • You won't be saying that once the market crashes. You'll realize that there are much better ways of spending that money. Like far more practical emissions reducing solutions.

  • Not really. It's mainly about gaining market dominance on a technology they think is the future. They'll build them right next to the massive coal plant alongside a million other things they're subsidizing.

  • It's the result of massive subsidies. When they stop, this market will crash like a house of cards.

  • Toyota’s chairman doubles down on his electric car skepticism, forecasting that EV adoption will peak at just 30%

    Jump

  • That's just BS. The longevity of everything is comparable to that of natural gas related equipment. It will be much cheaper than massively expanding the grid and build batteries for everything. Not to mention that you can reuse much of the natural gas infrastructure.

    Green hydrogen is growing exponentially in the same way wind and solar grew. The upside of something that isn't dependent on finite fossil fuels. It will eventually be available in vast quantities and at a very low price.

    Jump

  • At the end of the day, you are just turning sunlight/wind and water into a fuel. The marginal cost is nearly zero. Which is why the development trajectory will be the same as the rise of wind and solar energy. Both of those ideas also had nearly zero marginal cost. As a result, you can expect hydrogen fuel to be extreme cheap and basically inexhaustible. That is a major advantage and there is nothing batteries can ever do to match that.

    I wonder if you are projecting here: Hydrogen, not batteries, have many more applications. You can't even make the steel used to make a car without a reducing agent like hydrogen. Same is true of the metals in the battery itself. So if we want to hit zero emissions for real, hydrogen is mandatory, but batteries are not. In fact, BEVs are totally dependent on green hydrogen to real reach zero emissions. Everything from industry to long-duration energy storage all requires hydrogen. You can skip BEVs altogether but you cannot avoid hydrogen.

  • Those are wildly exaggerated. The main limitation is that society hasn't invested enough in hydrogen infrastructure. At least not yet. The problems would quickly go away if we did.

    You also forget that we've poured many billions of dollars into electrification and battery production. That amount of investment would have solved a lot of those limitations.

    As green hydrogen is made from water, there is basically no battery chemistry that can rival it in terms of availability. It is basically the best energy storage mechanism of this type already. Saying that batteries can get better is just misdirection. Also, you can have plug-in hydrogen cars too. The natural path is probably hybrids - PHEVs - plug-in FCEVs. Pure BEVs are in many ways a side-trip.

  • You mean from 20% to 80% charge? Which is realistically only 150 miles of gained range, and that's assuming everything is working at full power. The alternative gives you 0-100% in 5 minutes consistently. And best of all, it can be scaled up to trucks and above without suddenly realizing you need megawatts of power per station.

    In reality, the charging solution is much harder. We've just normalized the idea of using electricity to charge things when it is actually a bigger challenge than dealing with fuels.

  • One refueling station can serve thousands of customers, but a charging station needs multiple hours to charge each car. So you need far fewer gas stations. This is why the economics of gas stations worked out in the first place. Before, people bought tanks of gasoline and refueled at home. The gas station model was cheaper.

  • Not everyone can recharge at home. Hydrogen have all of the same advantages except recharging at home (and even this is a "kinda", because home refueling is possible, and plug-in cars exist).

    The problem is that we are hitting the limits of the BEV, and no amount of handwaving is going to make the problems go away. This mirrors the push for ethanol powered cars, and sudden realization that we cannot grow enough corn to make it happen. And fantasies about how China or whatever solving the problems is just a repeat of cellulosic ethanol, which was suppose to magically solve the problems of ethanol production.

  • Again, not everyone can do this. You will have to have public chargers. Plus fast charging for long distance driving. This will still require millions of charging stations, far more than any technology that allows you to refuel.

  • Toyota’s chairman doubles down on his electric car skepticism, forecasting that EV adoption will peak at just 30%

    Jump

  • That's the point: If you can refuel instead of recharge, you don't need that many stations. The number of hydrogen stations would be the same as the number of gas stations. And you have it backwards: You need vastly more charging stations than refueling stations. The US has something like 150k stations, and it's not even close to being enough.

  • Then you are just being old and outdated. It is totally safe.

  • You will need millions of charging stations everywhere. Both AC and DC charging stations. It is actually less straightforward once you go beyond home recharging.

    Jump

  • And a lot of people can't charge at home. You will still need public stations.

    In the end, this is just the whining of a handful of rich people. If it is more straightforward to get everyone to refuel at public stations, it is the better solution.

  • 2/3 is still not 100%. And you can refuel at home if you really wanted. In fact, you can even refuel a gasoline car at home. But in reality this was never a major selling point. It's just the crutch BEV fans are relying on. The refueling infrastructure is the only thing that really matters.
