    This is my main problem with hydrogen cars. I think it’s a very cool concept that might eventually overtake pure electric cars but there’s almost no places to get hydrogen yet.

      It also requires dedicated infrastructure. EVs can have charging stations at basically anywhere with a power hookup (or a genset. A grocery store here puts small VAWTs to charge off of in their parking lots. And every new-ish building has added charging stations to some of their spaces.

      Hydrogen cars would need refueling stations with dedicated pressurized gas hookups, tanks, and fill machines. And the tanks and the tankers to keep the tanks full.

      Finally the ultimate problem is it’s rather low energy density.

        And all that infrastructure is a problem that doesn’t need solving with EVs. An entire industry we don’t need to build/rebuild

      Something else no one has said yet (I think) is that most hydrogen is produced from natural gas, so this is in no way a climate solution. It’s been sold as one and it’s bullshit.

        Yes but not for long.

        As (generally climate denying) people love to point out, wind and solar is erratic power generation. For this reason you need triple capacity Vs requirements.

        This means that for a huge amount of time you’ll have excess energy, once we start to be predominantly renewables, battery storage is expensive. One of the solutions is to create hydrogen, also pumped hydrogen, etc.

      They’re still electric cars at their base. They just use a hydrogen reactor in lieu of a battery to power the motors.

      I don’t see a future where hydrogen supplants electric cars, unless there’s some revolution in storage technology for it. In that case, progress in battery tech is more likely.

      I dunno, everything I’ve always seen on it made it seem like a hyper-specific solution that’s more suited to a few edge cases that could have their specific infrastructure.

      For the average consumer, the recharging of EVs is actually Not A Big Deal™️. It seemed like one at first. Now all it does is ensure I take hourly short breaks which I should have been doing anyways, basically. The only big upside of Hydrogen is the ability to refill very quickly, but you pay with a whole bunch of downsides like inefficient generation, inefficient transportation, secondary infrastructure, energy inefficiency, etc.

      Another problem to the already mentioned ones (expensive, expensive dedicated infrastructure needed) is the range. Hydrogen is not very energy dense. For example the Toyota Mirai has a range of 500 km (310 miles) and its a pretty big, fuel-efficient car and the fuel storage is as big as the vehicle allows it.

      So while you can refuel faster than electric, you need to do it more frequently and its less convenient.

        The XLE does 410 miles. Few electric vehicle can touch that and EV ranges decline over time so almost no EV that’s more than a couple years old could match it.
