    I was excited for hydrogen back in the day but it seems like we’ve known for years that it isn’t the way to go. Why is anyone still fucking with it? Do these cars get 2,000 mile range or something?

      Hydrogen will be a big chunk of the future but probably not in cars, or generally car-sized vehicles, unless we’re talking stuff like catastrophe relief (and with that ambulances, fire trucks etc) because it’s a good idea to be able to fuel those things even if the grid is down.

      We’ll need hydrogen infrastructure and production anyways for steel smelting as well as the chemical industry, those are things that just don’t run on electricity, no way. With that in place hydrogen is going to be available pretty much all over, similar to how you get natural gas anywhere nowadays. And then you have an unelectrified railway somewhere, electrifying it would cost a fortune and not amortise, but a fuel cell locomotive? Sounds easy and reasonable. Flow batteries are also an option in that kind of operation but you really need a lot of space to get power output from those so they wouldn’t work for an ambulance.

      So if you’re a car manufacturer with your head screwed on right you’re probably not developing and selling hydrogen cars now because they believe they’re the future, you’re doing that to have affluent liberals pay for your ticket to play in the future market of hydrogen utility vehicles.

      Also of note: European car manufacturers at least seem to be completely fine with there being fewer cars on the streets. First, they can also make money off building public transport infrastructure and running car shares, secondly, cheap everyday cars aren’t that profitable, if the cars they then do get to sell are fancy with high profit margin that’s completely fine with them. Their suppliers care even less, a seat manufacturer doesn’t care whether the seat ends up in a car or a train.

        I’m curious how you see hydrogen being used in smelting. Hydrogen fuel cells do just produce electricity. Are you talking about something else, like combusting the hydrogen?

          Iron ore + hydrogen = Iron + water. It’s used to tear oxygen off the ore, currently that’s done with carbon, generally of fossil origin. thyssenkrupp is already doing it at scale. Not all the hydrogen they use right now is green but unlike the old furnaces the new ones are ready to be carbon-neutral, they just have to switch over fuel sources no need to mess with the furnaces themselves.

          It is possible to do the reduction directly with electricity but that’s less energy-efficient than going via hydrogen. For the chemical industry the situation is even more extreme they need hydrogen as an ingredient for the final product, not just as a reactant.

      The problem we have is energy density. Gasoline is pretty damn dense energy-wise. Storing 20-30 gallons of gas in a tank That’s easy and safe to refill is hard to replace.

      Lithium ion and lithium iron phosphate batteries are slow to refill.

      Hydrogen is kind of neat. You can make it from splitting water with solar or nuclear. It’s also a byproduct of the oil industry. And you can fill a tanker up or even an entire train and move fuck ton of hydrogen from one place to another. You can pipe it, people can generated for themselves and get a byproduct of pure oxygen.

      But alas, it’s still hydrogen. Give it access to the air in a little bit of fire and it makes a big boom. The infrastructure is very expensive to build out, and we’re not swimming so much and renewables then it makes sense to bottle it up and sell it to people.

        It can make sense for limited uses like cross country trucking (or maybe airlines) where battery will probably never have the range and you live and die by the schedule and refuel stops need to be relatively quick. Refilling semis at a limited number of truck stops with hydrogen stations can be useful if you can also get non petro-derived hydrogen. But for soccer moms and commuters it makes zero sense. Just charge smaller batteries at home and work and have a good interstate charging network for longer trips. We just need to normalize taking breaks on a road trip. It’ll help make more relaxing drives anyway and people already drive angry.

          I really wanted to see solar to hydrogen storage and then a hybrid fuel cell plus battery powerwall. Use all the solar that you get in the morning and not have to burn a battery pack out every 5 to 10 years.

          You could do the same with the car, throw a small fuel cell plant in there a couple liters of hydrogen and a decent but not too big battery pack. When you park your car at work or at home it just sits there and slowly charges when you’re not paying any attention. If it gets into a true low state or you know you’re going to need it the next day to go further you can plug it into your home electric. It’s just absolutely reasonable to put enough solar on a lot of houses that you could be completely sufficient from the grid.

      Yea it’s such a weird direction to go right night. Manufacturing and delivery of hydrogen for fuel cells is complex, expensive, and poses some unique dangers with the temps and pressure of the hydrogen. It’s cleaner, assuming manufacturing of the hydrogen uses green energy, but right now most energy production isn’t green.

      It has its advantages but some pretty big disadvantages too. I don’t think it’s the way to go just yet. Maybe eventually but not today I don’t think.
