Provenance Record

Clear, well-structured News piece (574 words, in range) with a sound Overview / What We Know / What We Don't Know / Analysis arc. Technical depth is appropriate and the article transparently surfaces the source conflicts in its own copy rather than papering over them.

All 4 source snapshots read from disk (gunzip) and verified. source-0.html.gz (Chronicle.lu, 200): confirms FID announced by Enovos on Tuesday 9 June 2026, 5 MW electrolysis unit, construction Q4 2026, commissioning 2027, EU/Clean Hydrogen Partnership/Luxembourg government backing, and the Anouk Hilger quote verbatim with correct title 'Head of Renewables Luxembourg'. source-1.html.gz (EU Clean Hydrogen Partnership listing, 200): confirms 650 ton/y, overall budget EUR 39,108,678, EU contribution EUR 7,999,999 (20.5%), project duration 1 Nov 2023 - 31 Jan 2029, 19 partners from 7 countries, mobility 69% (private & public buses, light industrial vehicles) / industry 31% (metal and glass manufacturing). source-2.html.gz (Encevo, pre-FID, 200): confirms Bascharage south Luxembourg, Enovos & LuxEnergie as Encevo subsidiaries, Ceratizit replacing natural-gas-derived hydrogen, Sales-Lentz & TICE FCH buses, University of Luxembourg as main coordinator through Prof. Bradley Ladewig, the Ladewig quote verbatim, ~EUR 39M budget with EUR 8M from the Clean Hydrogen Joint Undertaking. This older source lists the 6 MW design and the 1,750 kg/day figure. source-3.html.gz (University of Luxembourg, 200): confirms 5 MW electrolysis unit, construction late 2026, ready to produce hydrogen in 2027, coordinated by University of Luxembourg.

Strong. The two flagged source conflicts are handled honestly: the article uses the FID-era 5 MW capacity (corroborated by both Chronicle.lu and uni.lu), explicitly labels the older 6 MW as 'Earlier project descriptions circulated before the FID', and OMITS the conflicting 1,750 kg/day daily figure entirely, citing only the EU listing's 650 t/y. Budget, output, partner count and offtaker specifics are attributed to the EU primary listing / Encevo per Rule 9. No paywalled or 403 outlets (Hydrogen Insight, gasworld, fuelcellsworks) are cited. Internal cross-reference to the 2026-04 MIT 1S1 Energy article resolves to an existing file. One minor sourcing imprecision: the sentence 'brings together 19 partners from seven countries, with the University of Luxembourg as coordinator' attributes both facts to the EU Clean Hydrogen Partnership listing, but that listing states only the 19-partners/7-countries figure; the coordinator fact is sourced from Encevo and uni.lu, not the EU listing. The coordinator fact is true and independently verified in two other cited sources, so this is a recoverable misattribution documented in the corrections record. (Note: Encevo's pre-FID page says 17 partners; the article correctly uses the post-FID EU listing figure of 19.)

Substantively accurate, well-sourced News piece that handles the capacity (5 MW vs 6 MW) and output (650 t/y vs 1,750 kg/day) source conflicts honestly. The single recoverable issue is a coordinator-fact misattributed to the EU listing rather than to Encevo/uni.lu, which a corrections note covers cleanly. APPROVE_WITH_CORRECTIONS.
