"Each site would have carbon-sucking vacuums that could eliminate up to one million tons of carbon dioxide annually. This is equal to the yearly emissions of 445,000 gas-powered cars."
Another way to put it is, if we could instantly build 10,000 of these facilities today (which don't exist and are supposed to capture orders of magnitude more CO2 than any existing plant) and ignoring the cost/emissions from the construction and operation, and they instantly stored their ~1million tonnes of emissions, this would almost be enough to sequester ~1/3rd of last years emissions.
- mrweiner 3y agoHow’s your math work? If they sequester 1 million per year and we produce 5,600 million per year, 10,000 of these would capture nearly 2x one year of emissions, not 1/3.
- sillywalk 3y agoI'm terrible at math, so here goes: Global emissions of around 36+ Billion Tonnes/yr, so 10k facilities * 1Mtonnes_removed/year/facility = 10 Billion Tonnes removed /year. = < 1/3rd global emissions. not included: + all the wildfire emissions + whatever emissions it takes to actually create 10k+ DAC facilities, and operate them forever,
- mrweiner 3y agoAh, global emissions. I was confused because you’d responded to the comment about US emissions. Thanks for clarifying.
