About Us

Who We Are


Grannus was formed in 2012 to develop and bring to market next generation ammonia fertilizer production process technology.  Having developed technology that offers significant advantages over current steam methane reformer based designs; our patent pending technology creates synthesis gas that can be used as a feedstock in the production of ammonia and urea with virtually no emissions. The possibility of this technology was acknowledged at the 2013 Global Clean Tech Open where it was a Finalist in the National Competition. As air quality control measures become more stringent, Grannus’ technology becomes all the more attractive. But this ‘green’ advantage also comes with efficiency gains that enable Grannus plants to produce fertilizer at the lowest ‘landed’ cost in the industry.



As a next generation company, Grannus actively seeks a “portfolio shift to green” throughout its development pipeline. Implementing this philosophy means that we work to make each project we undertake greener than what it replaces, thereby doing our part to move the world towards a sustainable future. We aim to do this through process innovation, integration of renewables, combined heat and power, clean energy production, greenhouse gas reduction and sequestration, byproduct utilization, and emission credit creation.
