Hydrogen Injection Supplier Comparison

Most units on the market are alkaline cells sold on subscription with sizing benchmarks carried over from industrial applications. The differences below are the ones that change cost of ownership.

What to compare

Criterion	HydroHub™	Typical market offer
Cell technology	PEM, solid polymer membrane	Alkaline KOH bath
Gas purity	99.99%+	Scrubbed alkaline stream
Sizing basis	Engine displacement	Fixed gas-volume benchmark
Commercial model	Outright purchase, published prices	Subscription or lease, quote on request
Trial	Buy a unit and trial it yourself	Vendor-run trial with vendor-held data
Delivery	Free worldwide delivery, DDP where permitted	Freight quoted separately

Buy it and test it yourself

We publish prices and sell outright, so a fleet can put a unit on its own truck, log its own data and reach its own conclusion without entering a multi-year agreement. That is deliberate: the only trial data worth acting on is data you collected.
