In 2019, the Swiss start-up, which has raised more than $1bn from investors, predicted it would cut its capture costs from $600 per tonne to roughly $100 per tonne in “another four years”.

In reality the costs are still 2 to 3 times that, closer to $2000 per tonne. And that's not even taking into account the entire running costs of this ridiculous company, only operating their wildly inefficient plants.
If you actually go and divide their 1bn fundraising so far by their a bit over 1000 tonnes removed so far you end up with almost a million dollars spent for every ton of co2 removed, which I know is oversimplified but still shows how ridiculous this entire venture is.
