Sacchi and Bauer's final report is dated 21 June 2024. It describes attributional Swiss residential PtX chains with UVEK:2022, IPCC 2013 GWP100, cumulative energy demand and Swiss Ecological Scarcity 2021. The 2023 Zenodo release 1.0.1 is an earlier model stage; its 94% H2-boiler and 53% SOFC thermal efficiencies and allocation/storage assumptions differ from the final report and current compiler. They are not replacements for current recipes. Year 2020 in the original workbook is a scenario declaration, not every CLIC input's measurement year.

Publication and review
The two official PDFs have identical main 159 pages; FOEN appends Frischknecht's six-page review of 27 June 2024, v1.1. The imprint's DOI 5156043 resolves to vehicles; body section 1.3.7 correctly links residential concept 7955951 and release 8043744. A repeated workbook filename does not establish byte identity across later reviews. No standalone coefficient corrigendum was established. FOEN is commissioner, PSI the authors' institution and Frischknecht/treeze the external reviewer; those roles do not establish a grant number or funding of CLIC.
System boundary: One kilogram of the linked producer, 2.63e−10 liquid-storage-tank units and 0.5 tkm truck delivery per kilogram supply. Fuel combustion is a separate end-use process.
Technology description: Methanol provision from the linked coal producer, with a separate storage and freight wrapper.
Intended application: Methanol supply from coal under the retained production and delivery boundary.
Use limitations: Delivery and carbon origin
Freight of 0.5 tkm/kg is a 500 km equivalent, representing two 250 km segments rather than a 250 km total route. Exact producer and fossil/non-fossil carbon origin remain as archived. Biomass/coal boiler nodes already include direct delivery and must not receive this wrapper a second time.

Version metadata	Limitations on use	Final2024report and2023repositoryrelease1.0.1are different stages. Original2023allocation keys, boiler efficiency94percentLHV, losses/storage and SOFC53percent thermal efficiency differ from finalreport/current111percentH2boiler and33percentSOFC. Do not revert current recipes to earlier coefficients. OriginalfileYear2020is a scenario declaration, not proof of every later CLICrecord's reference year. The report imprint DOI5156043resolves to vehicles, whereas section1.3.7correctly links7955951, whose latestrelease8043744contains the originalworkbook. Both officialPDFs have identical main159pages; FOENadds six-pageFrischknechtreview27June2024v1.1. No standalone coefficient corrigendum found; reviewnames later dated versions of the sameworkbook, not proof that the June2023archive is the finalmatrix. Current4872is a distribution/loss auxiliary service: it purchases only0.006914348kgH2loss makeup perkgdeclared output, while source full-supply case includes1kgbasefuel. Current heat/electricityH2references buy genericmarketH2and do not explicitly call4872. Names/annotations mentionPEMgrid/pipeline, and someelectricity annotations sayAEC. Verify exact supplier and composition contracts before adding baseH2or delivery a second time; do not describe these as demonstrated completePEMgrid supply chains. Currentpaired fuel, water and leakage arithmetic agrees with stated final efficiencies and exergykeys. Published watercells inkg are about1million lower than physically normalized CLICwater afterkg/m3conversion. Preserve stoichiometric9kgwater/kgH2and1.125kgwater/kgmethanol relationships; do not copy printed decimal/unit conflicts as corrections. CHPsource25mgNOx/kWhthermal is reused as an end-use proxy. Currentheat6.944e-6kg/MJand electricity2.5e-5kg/kWhare independently fixed; recombining outputpairs does not conserve that common-combustion thermal basis. Two coupled conditional candidates would partition one sharedfactor usingexergy. Confirm common-emission ownership and reject if independent product-specific factors were intended; not a published erratum or measuredmanufacturer correction. Equipment burden formulas use input-relatedkWdenominators even where supplied equipment references are expressed peroutputcapacity. CHP/PEM/SOFCpower ratios and stated efficiencies are not consistently aligned. Common/heat-only/electric-only components, lubrication, fuelcell replacement and assembledsystem sizing require coordinated reconstruction; no isolated asset rescale proposed. SOFCcurrent allocation0.0816448898implies the same effective heat-exergyfactor as PEM85/40degree assumptions, not CHP60/35. This is inferred currentcompilerbehavior, not an explicit temperature table in the finalSOFCsection. H2boiler auxiliaryelectricity0.000734kWh differs from original2023andfinal2024printed0.00264kWh byabout3.6; the actual source-service unit must be checked before changing it. Currentmethanol boiler uses9kWoutputbasis, unlike printed6.61e-7unit using10kWinputbasis; do not apply a common rescale across devices. Reportexecutivesummary and appendedreview disagree on fixed combined-output basket ratios. Neither is automatically the physical co-product ratio implied by each technology's efficiencies. Use explicit oneMJheat/onekWhelectricity references and documentedpaired allocation; no mixedbasket comparison or macro-system investment conclusions from current attributional single-technology models. Methanol freight0.5tkm/kgis a500km-equivalent route (two250kmsegments), not evidence of a250kmtotalroute. Current4911/12already add0.0277778tkm/MJdirectly; do not add a supplywrapper again. Currentcoalmethanolcarbon is fossil, biomass/DAC cases non-fossil. Preserve currentfixes; biomethane/LPGandcoal gas references remain supplier-specific proxies, not reported complete dedicated fuel-chain recipes. Gas boiler/SNG/biomethane/LPGuse common LHV48MJ/kgand109.5percentLHVboiler assumptions in the compiler. These are not verified LPGcomposition/efficiency or methane purity. Condensing efficiencies above100percent onLHVbasis are not by themselves energy-creation errors. Methanol uses20MJ/kg and90percent; finalreportalso prints19.9MJ/kg and a different oil-boiler coefficient. Keep these conflicts explicit. SNG2082/4880is named catalytic methanation, but its actual supplier is named electrochemical methanation with atmospheric carbon. Verify the actual supplier technology before claiming the published catalytic pathway. The source pathway name alone is insufficient. Grid-balancing2105applies0.25percentproduction plus30percent*(1percentstorage+1.3percentcushion)loss to fuel makeup0.0094kg, but purchases geologicalstorage for1.0094kginstead of only30percent. Review partialcycling, initialcushion and whether loss totals useoutput orinput bases before quantity changes. Its30barPEMprovider,80baroutput and0.88kWhcompression are specific assumptions, not a full time-resolved dispatch model. FOENis reportcommissioner, PSIauthors' institution, andFrischknecht/treezethe external reviewer. No grantnumber or inferred financialfunding added. The appended review itself notes singleexpert/singlescore limitations and attributional microscale scope; it is not independent certification of the laterCLICadaptations.	Delivery and carbon origin Freight of 0.5 tkm/kg is a 500 km equivalent, representing two 250 km segments rather than a 250 km total route. Exact producer and fossil/non-fossil carbon origin remain as archived. Biomass/coal boiler nodes already include direct delivery and must not receive this wrapper a second time.
