Source Review: Lyon Industries — ISRU 2026 ("Oxygen Ready, Water Not")
Summary
| Verdict | Count |
|---|---|
| Consistent | 5 |
| Different conclusion | 0 |
| Novel supporting | 2 |
| Merits investigation | 1 |
| Not relevant | 0 |
Claim 1 — Oxygen ISRU TRL synthesis
Quote: "TRL 6" Sierra carbothermal; MRE TRL 4-6 (Lunar Resources + Blue Origin); H2/CO reduction TRL 5-6 for equatorial sites.
Verdict: Consistent (q3.c3)
Why: Matches my derived TRL distribution. Adds Lunar Resources + Blue Origin to the MRE landscape (I had only Sadoway lab + Helios in my calc — see Schreiner extract).
Claim 2 — Carbothermal production rate
Quote: Sierra Space carbothermal "140 kilograms of oxygen per year" single reactor melt-cycle equivalent.
Verdict: Consistent (q3.c12)
Why: Matches NASA Sanders 2025 figure of 140 kg O2/yr equivalent from single-melt runs.
Claim 3 — Oxygen extraction efficiency
Quote: "Greater than 20 grams of O₂ per kilowatt-hour of thermal input" → 50 kWh/kg O2.
Verdict: Consistent (q3.c2)
Why: Direct support for the 50 kWh/kg O2 wall-plug figure used in my calc's process feasibility matrix.
Claim 4 — Oxygen-from-regolith provides 75-80% of propellant
Quote: "75 to 80 percent of propellant mass with the fuel still shipped from Earth"
Verdict: Novel supporting (q3.c4, q3.c5)
Why: Crisp framing of why oxygen-only ISRU still wins the bulk of the propellant battle. Aerospace America cites 70-80% for the same ratio. Supports my q3.c5 conclusion that even without lunar fuel, the LOX portion of LH2/LOX is a meaningful ISRU prize.
Claim 5 — "The rocks are ready, the ice is not"
Quote: "The rocks are ready" — oxygen and metals from dry regolith are now a "manufacturing and integration problem"; "The ice is not" ready — still a "prospecting problem."
Verdict: Novel supporting (overall feasibility verdict)
Why: Concise summary of the lunar ISRU landscape that aligns exactly with my framework. The "manufacturing and integration" framing is consistent with anti-pattern #11 — the remaining problem is not science but engineering execution under whichever acceleration regime obtains.
Claim 6 — OxEon water electrolyzer TRL 5
Quote: OxEon SOE stack at "TRL 5" producing "0.9 kg/hr of oxygen and 0.12 kg/hr of hydrogen from electrolyzed water."
Verdict: Consistent (q3.c14)
Why: Direct source for the OxEon TRL 5 + production rate claim.
Claim 7 — Polar ice extraction TRL 4-6
Quote: Water extraction approaches at "TRL 4 to 6"; "extraction efficiency from ice cores: 43 to 56 percent of contained water from 5cm diameter cores."
Verdict: Consistent (q3.c4)
Why: Confirms polar-ice extraction sits at TRL 4-6 for the extraction step even though resource characterization remains the binding gate.
Claim 8 — Resource knowledge gap
Quote: "Lacking sufficient resource knowledge to proceed without significant risk" — "how much water there is per kilogram of regolith, what mineral or physical form it takes."
Verdict: Consistent (q3.c4)
Why: Direct support for the prospecting-gated H2 ISRU framing.
Claim 9 — Prospecting timeline
Quote: Artemis IV 2028; VIPER late 2027; ESA PROSPECT 2026; Chang'e-7 August 2026; JAXA-ISRO LUPEX + Korea KIGAM LUVED "next two years."
Verdict: Merits investigation
Why: A coordinated 2026-2028 prospecting wave will dramatically change H2/H2O resource confidence. Could spawn tree node: "How does the 2026-2028 prospecting wave shift q3's polar-ice claim trajectory under TAI-C vs BAU?"
