The Grannus Advantage
- Clean hydrogen/ammonia manufacturing with the reduced production and construction costs of traditional “gray” SMR plants.
- Accelerated lower-risk project development due to lack of criteria air emissions. Does not require Federal major source air permits.
- Two-year construction schedule, local ministerial permitting typically 6 to 10 months.
- Repeatable modular phased projects that are ideally sized for financing and supply of regional syngas, ammonia, and hydrogen.
- Requires 80% less water than traditional “gray” SMR plants.
Greener Projects, More Sustainable Futures
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.
The Grannus Process
Grannus’ fully commercialized technology is used to build near zero emission projects that produce synthetic gas for the manufacture of downstream chemical products along with the cogeneration of clean electric power. Our multi-feedstock technology integrates a partial oxidation reactor with a water gas shift and purification process to make synthesis gas into hydrogen gas, ammonia, or other products. Each stage of the process produces steam that is used to generate electricity, thereby increasing total plant efficiency. The process offers flexible hydrogen/carbon ratios that are suitable for use with a number of production processes including Haber-Bosch (ammonia), Bosch-Meisner (urea), or Fischer-Tropsch for sustainable fuels. The Grannus process offers many advantages over steam methane or autothermal reformation traditionally used to produce syngas. By utilizing 100% of plant feedstock for the production of syngas we are able to eliminate the emissions stack associated with a traditional plant design. No emissions stack means no stack emissions. This paradigm shift allows distributed, modular construction of clean, near zero-emissions process plants while maintaining the economic advantages of traditional production designs.
