Carbon Capture
CDR encompasses myriad techniques and technologies: direct air capture, carbon storage and sequestration in natural basins, bioenergy with carbon capture, reforestation, carbon-friendly soil management practices, ocean enhancement, and many more. Each method has different rates of CO2 uptake, land requirements, energy demands, storage permanence, a... See more
Roger Deane Aines • Carbon Dioxide Removal Primer
At 2.13 GtC equivalent to1 ppm carbon, this means that the current (idealized) costs of AC are about $1 trillion per reduced ppm of atmospheric CO2 at a cost of AC equal to $500/tC.
Bjørn Lomborg • Smart Solutions to Climate Change: Comparing Costs and Benefits
That’s called carbon capture and storage, and it involves installing special devices at fossil-fuel plants to absorb emissions. These “point capture” devices have existed for decades, but they’re expensive to buy and operate, they generally capture only 90 percent of the greenhouse gases involved, and power companies don’t gain anything from instal

Companies are working on new materials that are better at absorbing carbon dioxide, which will make both point capture and DAC cheaper and more effective. In addition, today’s approaches to DAC require a lot of energy to trap the greenhouse gases, collect them, and store them safely. There’s no way to do all that work without using some energy; the
