Grannus LLC | Zero Emission Hydrogen & Ammonia Production

Breaking New Ground

Breaking New Ground.

Grannus is building a next generation hydrogen and ammonia production facility that produces effectively no emissions and meets the efficiencies of today’s best-in-class designs at a fraction of the size.

No Emissions

Effectively No Emissions.

Grannus’ technology and plant design reduces criteria pollutant emissions to “near zero” or unmeasurable, with emissions 100 times or more below the minor source air permit application exemption threshold in most jurisdictions. This has resulted in a precedent setting “exemption from air permitting” from the Federal government that reduces project risk and shortens time to plant operations. The Grannus Process was also entered into the U.S. EPA RBLC clearinghouse as clean technology for the production of hydrogen or ammonia and their derivatives with a “zero emission” limit.

Who We Are

Cleantech Emphasis

Grannus is a Cleantech Project Development Company focused on selecting technologies and processes that improve the project’s environmental profile while simultaneously delivering attractive returns to stakeholders.

Proprietary Process Technologies

Grannus’ patented multi-feedstock Grannus Process™ plant design has been fully commercialized as has been added to the U.S. EPA RBLC clearinghouse for both hydrogen and ammonia production. Grannus Process™ plants can utilize a variety of carbonaceous feedstocks including natural gas, petcoke, and Municipal Solid Waste (MSW).

Partnering for Successful Outcomes.

Grannus’ executives have extensive experience in building consortiums of companies to design and build ‘clean-tech’ production and renewable energy facilities. These consortiums supply key engineering, construction and processing equipment to its projects.

Wide Ranging Experience

Grannus has built relationships with a number of Tier 1 companies that will supply key engineering, construction and processing equipment. It is our intent, in working with our partners, to design and build ‘clean-tech’ syngas, hydrogen, ammonia, and other downstream chemical manufacturing plants that produce virtually no emissions and exceed the efficiencies of today’s best-in-class design at a fraction of the size.
