Pull request overview
This PR updates the cost/energy assumptions for the CO2 liquefaction technology (used for CO2 conditioning/compression for transport) by replacing the previous Mitsubishi/IEA (2004, ship transport) reference with values from the 2024 AIT study, and propagates the update into generated output cost tables (global and US) plus release notes.
Changes:
- Replace
CO2 liquefactionCAPEX/FOM/electricity-input source data with AIT study values (and remove the previous heat-input row). - Update
inputs/manual_input.csvso the compilation pipeline produces the newCO2 liquefactionoutputs. - Add an “Upcoming Release” note documenting the CO2 dense-phase compression update.

Is this really needed in technology data? Consider moving it into config.default in pypsa-eur workflow.

Following the data structure so far. I don't want to break people's code but happy to discuss.

Generally looks good to me, two comments
- consider moving
CO2 liquefaction,carbondioxide-input,0,1,t_CO2/t_CO2,-,,into config.default of the pypsa-eur workflow, as this does not add any new data to technology.data - Add to release_notes the rather big change in CO2 liquefaction capital cost (which make sense as the previous value was simply wrong)
