- Removed geothermal-sourced heat pumps and fixed previously underestimated costs for geothermal heat source. Recommendation: Use excess-heat-sourced heat pump data for geothermal-sourced heat pumps (only the heat pump part of the costs!) and consult the DEA technology catalogue.
- Removed water-sourced heat pumps, as cost assumptions (based on higher uncertainty range in DEA tables) are a) likely overestimates and b) break pessimistic/optimistic scenarios. Recomendation: Use excess-heat-sourced heat pump data or see DEA data on seawater-sourced heat pumps.

Updated technologies (based on reviewer comments and subsequent investigation): (cf.`Pull Request #57 <#57>`_) - Methanation:
- Less optimistic number from report comparing multiple sources (incl. the source of the original number)
Fischer-Tropsch: + Mature technology (Hydrogen + Syngas to FTFs) + Account for economies of scale (previous numbers for very small installations) + Do not take value from DEA which is more focues on integrated Power-To-Liquid plant with low integration TRL + Use same value for Fischer-Tropsch and Methanolisation based on source report + Remove VOM for FTF, not reported in many sources and DEA numbers not reproduceable with original source
Methanolisation: + Mature technology (Hydrogen + CO2 to MeOH) + Account for economies of scale (previous numbers for very small installations) + Do not take value from DEA which is more focues on integrated Power-To-Liquid plant with low integration TRL + Use same value for Fischer-Tropsch and Methanolisation based on source report
Ammonia cracker: + Mixed existing/new technology with existing large plants (for different purpose) + Consider plant size: Higher scale up based on previously considered reference with expected economies of scale
H2 liquefaction: + Consider larger plant sizes based on recent IRENA report leading to economies of scale + added: lower 2050 value + Match plant size to other similar facility sizes (LOHC hydrogenation) in repository

This release allows to include uncertainty bounds from the Danish Energy Agency (DEA), fixes inconsistencies with the handling of combined heat and power plants, and includes the latest data from the DEA on carbon capture technologies.
It is released to coincide with PyPSA-Eur Version 0.3.0 and PyPSA-Eur-Sec Version 0.4.0, and is known to work with these releases.
Features in more detail:
- Using the
expectationparameter inconfig.yamlyou can control whether the upper and lower uncertainty bounds on technology parameters are read in from the DEA datasets. - The biomass and gas combined heat and power (CHP) parameters
c_vandc_bwere read in assuming they were extraction plants rather than back pressure plants. The data is now corrected and they are implemented in PyPSA-Eur-Sec Version 0.4.0 with a fixed ratio of electricity to heat output. The old assumptions underestimated the heat output. - The updated assumptions from the DEA for carbon capture technologies have been incorporated, including direct air capture and post-combustion capture on CHPs, cement kilns and other industrial facilities. These are then used in PyPSA-Eur-Sec Version 0.4.0.
This is the first release to coincide with the release of PyPSA-Eur-Sec Version 0.2.0.
