About Us

Who We Are


Grannus develops and commercializes next generation syngas, hydrogen and ammonia production process technology. Its patented Grannus Process™ offers significant advantages over current steam methane reformer-based designs – it creates hydrogen that can be used as a feedstock in the production of ammonia and urea with effectively no emissions. Grannus received accolades at the 2013 Global Clean Tech Open as a Finalist in the National US Competition for best innovators in clean-tech. 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 product at the lowest ‘landed’ cost in the industry.



As a next generation clean-tech 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, beneficial reuse of waste products, and emission credit creation.
