The costs of Direct Air Capture will not fall as much as hoped. "Efforts to reduce carbon emissions should therefore* continue at pace, says the research team."
*Therefore is problematic here, as it implies that if DACCS was cheap less reductions are needed. No, no, no.

Anders Opedal (CEO of Equinor) said something wrong here.
He said that the IEA said no need for new oil and gas before, now they say more oil and gas needed. This is wrong.
The no new oil and gas is if demand drops in line with 1.5C, and always has been.

The atmospheric increase of CH4 has returned to "normal" levels in the last couple of years, after big increases in 2020-2022.
The 2020-2022 increases were likely anomalies (COVID, weather), and not a change in trend.

Experience curves indicate that successful technologies reduce in cost by ~20% for each doubling of cumulative production.
However, we find that past learning rates are not very predictive of future learning rates, throwing many energy tech cost projections into doubt.
