Our vision is to support human flourishing through secure, affordable, and clean energy. Thiozen began at MIT with a question: what if hydrogen sulfide, a troublesome contaminant found throughout the energy supply chain, were treated as a resource instead of a waste? As a Ph.D. student in MIT's Department of Chemical Engineering, Ryan Gillis worked with Professor William Green to develop and patent a thermochemical cycle that reforms sour gas into clean hydrogen and sulfur products. Ryan and Bill met Ajay Bawa, then at MIT Sloan, in a class called Energy Ventures, where the three founded Thiozen to take the chemistry out of the lab and to market.

That work led to our first field pilot in the Permian Basin and the two products we offer today: Zen, a modular system that removes hydrogen sulfide and recovers elemental sulfur at a fraction of the cost of conventional treating, and ZenH2, which extends the same chemistry to produce zero emission hydrogen and fertilizer.
