About us

Not the Biggest Name.
Just the Best Results.

We’re problem solvers. While they kept selling the same broken systems, we started over and built a faster, longer-running catalyst from the ground up.

Founder Mike Callaway spent 40 years in oilfield chemistry. He saw the gaps in the market and created a dry catalyst that exceeds the capabilities of all others on the market.

We’re family-owned, agile, and committed to working directly with you to uncover the right solution, not just the easy one.

Real Feedback

Nothing Beats Real Experience.

"Met all expectations — and then some."

“We had a great experience working with H2SZERO. Drew was incredibly easy to work with—he took the time to explain the entire process clearly and thoroughly, which made everything smooth and stress-free. His support throughout was top-notch. The vessels themselves performed exceptionally well, meeting all expectations and then some. We were very satisfied with both the service and the product.”
