E-fuels or storage – how to make the most of clean electricity and captured CO2 Clean electricity and captured CO2 have multiple uses. Regulation should aim for prioritizing these resources for applications with the highest climate benefit

Speaking of not being given other options… use of hydrogen for carbon based fuels (e.g. aviation fuel) is a poor use of ressources.
Just store the carbon needed for synthesis instead.

Thanks for sharing the numbers!
Did you make a table? It seems relevant to try to construct a carbon storage supply curve. If the value of additional storage is 100-300 €/ton CO2, then I would suspect you could find significant additional room underground.

Has anyone looked into using CaO instead? Same result but only 30 % of the mass.
Calcination with CCS would need to be done on land.

Thanks for sharing! Have you made any assessments of how the overall ESR target compliance is coming along? www.transportenvironment.org/uploads/file...

Any recording of your keynote or link to the presentation?

If its “long-term” you could bring down temperatures again using negative emissions. Question is who is going to pay.

Thanks! Flaring is bad, but also a much smaller problem than energy use.

And higher EU ETS prices.
Do you have the numbers for energy use emissions?

Graph of the climate benefit from a kWh of green electricity used on various purposes, clearly showing that e-fuels is last in line

🛫 More routes to climate-neutral aviation! 🛫

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.

What about round trip efficiency? I’ve heard they’re unfortunately only getting about 50 %.

Do you have a graph showing fuel costs in USD/litre?

Yes. When assuming that the upgrading plant is paid for and in operation already it’s fairly cheap to transport and store the CO2 removed in upgrading.
