Claims vs Record disc-037
claim not supportedtechnical 'Cheap and abundant hydrogen' via a sulfur-iodine process: no hydrogen on record, and the process has never run commercially

The gap: The home page states, in the present tense, that Valar's reactors paired with its sulfur-iodine process produce cheap, abundant hydrogen. It can be read as a description of design intent ('When paired with'), but no hydrogen production is on record, the process has never been deployed commercially (per a Valar investor's own profile), and it needs heat of about 800-1000°C. The only Valar reactor with a public safety paper, the Ward 250 test unit, is limited to 650°C; Valar describes its future designs as hotter, but none has a public safety paper.
In plain termsValar's home page says its reactors, paired with a chemical process called the sulfur-iodine cycle, make cheap and plentiful hydrogen. Read kindly, that describes what the design is meant to do. But no record shows Valar has made any hydrogen, the process has never run commercially anywhere (according even to a Valar investor), and it needs heat of roughly 800 to 1,000°C. Ward 250, the only Valar reactor with a public safety paper, is a test unit limited to 650°C; Valar's future reactors may run hotter, but none has a safety paper yet. The hydrogen plan may come true one day; today it is written as if it already works.
Why it matters: Claims on the company's front page shape what investors, officials and neighbors believe the technology does now.
What would settle it: Valar publishing any hydrogen-production test data, or rewording the page as a goal.
