While capturing and liquifying the CO2 may prevent immediate release into the atmosphere, you still have to do something with it. Where would you sequester a billion gallons of liquified CO2 each year?
- m_mueller 10y agoThat is exactly the issue. If you really want to solidify the carbon for long term storage, you'd have to spend more energy than you gain in the first place. At least I'm not aware of a process that could capture CO2 for long term storage with only a fraction of the Carbon-to-Carbon binding energy (which is what you gain when burning, minus the C-O2 binding.
- infinite8s 10y agoThis is exactly what photosynthesis accomplishes, using energy from the sun.
- m_mueller 10y agoAt which point you can just use solar cells and batteries? I mean you do get high energy density with coal, but the downsides just seem too much.
- adamiscool8 10y agoIsn't liquid CO2 used as a coolant? Sounds like we have our global warming solution.
- Johnny555 10y agoOnly if by "Global Warming Solution" you mean that it will cause more global warming. Liquid CO2 boils away (solid CO2, i.e. "dry ice" sublimates) as it cools, so it'll still be released into the atmosphere.
