Claim
The reported seawater-hydrogen system operated stably for 100 days at 20 kW, producing 3.8 Nm³ h⁻¹ hydrogen and 1.2 kg h⁻¹ freshwater; at 250 kW it produced 48 Nm³ h⁻¹ hydrogen and 31.6 kg h⁻¹ freshwater, with 14.4% higher electrical efficiency than alkaline electrolysis using freshwater alone.

Assessment
Supported
Main unresolved issue: 3 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:29526bc5-3f22-89b3-ab1a-2ab1739dba48
Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage from nature.com was not found on the page when Galedra fetched it.
Why?
Strongest counted support: The study reports 100-day stable 20-kW operation and 250-kW scale-up with specified hydrogen, freshwater, and efficiency results. weight 2.000000 evidence
Suppressed as dependent: The passage directly reports 20-kW 100-day operation, 250-kW outputs, and the 14.4% efficiency comparison.
Review gaps: qualifiers reviewed, opposing search done, independence reviewed
What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

Threads
None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Summary
Supported. The main support is: The Nature Energy report directly documents the 20-kW pilot's 100-day operation and the 250-kW scale-up outputs and relative efficiency improvement described in the claim. 481722b8
