  • Do they think they just sorta dig wells in random spots and never think about the science of it?

    I mean yeah, kinda. The Three Cups of Tea guy built a bunch of schools that are being used for storage sheds because he didn’t have any idea of what it would take to run a school in Afghanistan. Peace Corps is basically make-work projects for idealistic college grads with no real world experience. The Gates Foundation built high tech toilets for rural areas that were stripped for metals pretty much immediately. Tons of nonprofit money is wasted because anyone can raise money thinking the solutions are simple and then discover that the reality is a lot more difficult.

    Effective Altruism had the kernel of a good idea in that it initially proposed that interventions be evidence-based and actually help the most people. But then they got bit by a radioactive Utilitarian or got lots of money from someone who knew that the real purpose of philanthropy is reputation laundering and suddenly it was all about kajillion simulated space consciousnesses and flimsy justifications for protecting the incomes of software engineers at Facebook.


  • Well yeah, degrowth is a precondition to any of the mitigation technologies on that list. The water’s coming in into the boat way faster than we can bail, so the priority should be to plug the leaks.

    The chart reflects the fact that CCS is an immature technology that will be a nice to have if we can drop the energy requirements and store carbon in a form that’s stable at normal room temperatures and pressures. There’s some bench-scale experiments that have had promising results to that effect, so I don’t see any reason not to fund that research. We spend more money on worse stuff by a country mile.

    Plus, all the other bars on that chart have their issues. The mineral requirement to build transmission and storage infrastructure for wind and solar at current rates of energy demand growth will require massive increases in mining for copper and lithium. Agricultural carbon storage has error bars you could drive a truck through because no one can measure it. Attempts to pay farmers for soil carbon sequestration have been a mess and we’re not sure about what the turnover rates for soil carbon pools might be under a warmer and wetter climate. Forest preservation just avoids future emissions and many forests are switching from carbon sinks to sources as they catch fire.

    Fuel switching to natural gas: A recent study suggests NG is probably worse than coal. Plus quantification of leakage is notoriously messy.

    We’re kinda boned and CCS only really makes sense under FALGSC conditions, but it could help if we manage to pull out of our capitalist nosedive.


  • While I get the skepticism about CCS because capitalists are idiots, I don’t know about “can’t work”

    CCS is great if:

    • We have a compact and stable form of storage (salt mines may be leaky or a seismic hazard on the very long term)
    • We’re producing carbon-free energy in excess of what we need for everything else (i.e., China figures out fusion), or we have low-energy methods of extracting carbon from the atmosphere that don’t require substantial power draw from the grid and are easily scalable (certain kinds of catalytic conversion that haven’t made it off the lab bench could work, but the scaling question hasn’t been addressed yet)
    • The captured carbon is not being used to extract more fossil fuels (strange how many people miss this step)

    The elephant in the room here is time, because you can’t just hoover up gigatons of carbon overnight. So long as it doesn’t take resources away from more immediate forms of mitigation and adaptation, I think it’s research worth pursuing. But the IRA’s drafters didn’t get that memo.
