Sustainable aviation fuel (SAF) plays the same role in aviation as CCS/BECCS/DACCS play for other fossil-fuelled sectors: more a stalling tactic than solution. Good engineers work on SAF, but CEOs/politicians/etc deliberately mis-sell their role in mitigation.

No great answer to this beyond taxpayer but a utility style rate system plus public finance could probably shave off 10-15% of the cost which would be nice. I fantasize about some peak load management + daccs business model but that might be a fantasy. The problem is geoengineering will be too cheap

In a new CONCITO paper we argue for using green electricity and captured CO2 separately, as:
- The climate benefit is double that of e-kerosene
- This displaces more fossil fuel
- It is more cost efficient.

At this point, the carbon offsets that provide irrefutable benefits are when the polluter pays for an equal amount of CO2 to be removed and kept from going back into our polluted atmosphere via DACCS.
Anyways, while people are still flying and such I think they should try to remediate that damage.

Here are the levels of different CDR methods in the 1.5C scenarios (with no or low overshoot) assessed by the IPCC.
In 2050, the IEA NZE2050 has ~1GtCO2 BECCS and about 0.7GtCO2 DACCS.

I think there could be a place for DACCS as part of a serious treatment of GHGs, if they cost less than SCC (i.e., use them to remove emissions that can’t be abated more cheaply by other means). But we should first do everything that costs less. And we’re not moving well on that front.

I was hoping to get some response from people with expertise, but thanks. DACCS does not require hydroxides at all for many of the emerging technologies.
Most advanced DAC facilities use specialized filters to extract the CO₂ from the ambient air.
My favorite technology is biochar btw.

However DACCS can still have a small role to balance remaining emissions and maybe more importantly, if airlines were required to have an fast increasing amount of synthetic fuels with carbon from DAC, the increased cost would dampen the demand for flights and make alternatives more attractive. 3/3

Thank you for your comprehensive answer. I agree totally that those "offsets" which airlines provide are useless (already evident by their low price - if solving the problem was really so cheap we'd already done it). DACCS also has some of the issues, like those mentioned in your post. 1/3

Pour l'instant, c'est une poignée d'entreprises/d'individus qui paient volontairement très chers pour éliminer du CO2 de l'atmosphère dans un monde où la pollution peut se faire encore très librement. Dans un tel monde, la DACCS n'a pas d'avenir et restera anecdotique.
