  • You keep jumping back and forth between biofuel and biomass. You can bury solid biofuel, you can pump liquid biofuel, both are stable if you put them somewhere without much oxygen

    Biomass is something different… Do it right and you can just use it as fertilizer. Just grow a bunch of algae and spray it over dry land… It’s that easy. It’ll feed the soil, which locks up a lot of carbon back into the food chain. Stack wood in a desert, who cares. There’s so many better ways to do this

    And CO2 is a fucking gas. Yes, it’s liquid under pressure or at low enough temp… But it does not stay that way! We live in Earth, and most cavities aren’t able to stay pressurized without leaking





  • I get what you’re saying, it sounds very reasonable conceptually. But the problem is that this is a chain so riddled with weak links it’s infeasible

    You’re right about biofuel… Except that biofuel is already refined biomass. The water is already removed, usually to become as close to pure hydrocarbons as possible. That’s a far more efficient CO2 sink than pure CO2, because the oxygen component is in the atmosphere

    It’s insane to burn biofuels to lower atmospheric CO2.

    And as far as the process being non-destructive… This technology was developed to use pressured CO2 to break smaller pockets in the rock, it’s like using a pressure chamber to deflate foam. Except the rocks aren’t plastic until your get a whole lot deeper, and the amount of pressure means the whole well is being pressurized beyond a level it was ever at naturally

    Can a big cavity in the Earth store gasses? Sure. Can an oil well? Maybe… But so far, the answer is it leaks

    As for your last point… If you instead ask if we should cram biofuels in the ground? That’s a way better idea, there’s something to it. It’s not a solution, it doesn’t scale to the levels where we can keep using fossil fuels everywhere, but it would sequester C02 very effectively. Kind of like it was before we dug it up and burned it


  • The biofuel thing is just further nonsense.

    If you’re pulling CO2 out of the air, why in the world would you turn around and burn it???

    That makes zero sense. For one, biofuels require processing, which means they might even be carbon positive before you burn it, and again, the scale needed to produce it in meaningful quantities is totally impractical.

    And again, you can’t just pump CO2 in the well and put an acme sized plug on it. The structure of the rock is destroyed by the process, it’ll just leak out. We’d need an entirely new method to store it, which was never the plan here

    This whole scheme is a fever dream designed to continue burning fossil fuels while siphoning away money from actual green movements



  • You don’t understand… We already know it doesn’t work. They’ve been doing this for decades, they’ve recently started green washing this fracking technique

    And in case you didn’t know, there’s dozens of oil wells leaking right now. Some is oil in the ocean, some natural gas, some of it is burning underground… And there’s just no known way to stop it. You can’t just seal them back up when you’re done, the structure of the rock is damaged

    And all of the aside, this doesn’t math even if it worked. It takes too much energy to pull CO2 out of the air, and to even make a dent we’d have to put up CO2 condensers on a percentage of earths surface… It’s a dead end tech.

    A distraction from the truth… We just have to reduce emissions. It’s that simple, we have to do it before the systems that keep Earth stable flip and accelerate warming
