"Our plants require less land than other techniques. E.g., on a land area of 0.42 acres, our Orca plant can remove 4,000 tons of CO₂ from the air every year, which is almost 1,000 times more effective than trees. The same land would host around 220 trees with an estimated capacity of 22kg each"

How much land, in solar panels for example, is required to power this?

Also what's the carbon waste that this generates? Is there a synergistic use for it?

The way I see it is that we are way beyond all reasonable bounds already, concerning co2 ppm in the air. Even if we stop all emissions this very moment, there’s still way too much already in the atmosphere. So, we are going to need co2 removal either way if there shall be any hope of ever returning to a world climate similar to before 1980.

I am no expert in the field, but this is an area that at least gives me some positive outlook on the future. I could imagine, for example, that we start over provisioning electricity with renewables; and instead of scaling them down when there is no energy demand, we will redirect the superfluous energy into carbon capture.

I've wondered the same about these carbon capture plants. Is this literally just elemental carbon in some kind of dust/sand at the end of the day? Could this be a raw material input for carbon fiber production?

Superfluous renewable energy already has to go to hydrolysis to produce hydrogen to be saved for times whenever renewables don't produce energy.

It says "The CO₂ can then be safely and permanently stored underground by our storage partners — Carbfix in Iceland."

So my assumption was that the collectors are located there as well and using Iceland's abundant geothermal electricity.
