Grannus has been chosen as Best Available Control Technology (BACT) by the US Environmental Protection Agency (EPA) for its hydrogen (H2) and ammonia production technology – Grannus Process™.
The designation was achieved because the processes’ emissions levels are well below Federal, State and local permit application requirements – even in non-attainment zones. The reference plant’s design will produce 250 tonnes of ammonia (or the equivalent of 46 tonnes of H2) per day and emit less than 2 pounds per day of criteria pollutants, well below current BACT standards.
Kelly Merritt, Grannus’ Chief Development Officer and co-founder, said, “BACT certification confirms the Grannus Process has the lowest emissions level in the industry for production of H2 while maintaining cost competitiveness at a scale relative to competitors’ designs.”
“With this certification, all new H2-based plants, whether they are greenfield or retrofit projects, will be required to meet the Grannus Process emission levels,” Merritt continued.
In addition to achieving BACT, Grannus announced the issuance by the US Patent and Trademark Office of a new patent encompassing a novel method for production of H2, ammonia and Fischer-Tropsch products. The patent, US 9,957,161 is entitled ‘Polygeneration Production of H2 for use in Various Industrial Processes’.
Grannus CEO Matthew Cox, commenetd, “The BACT designation coupled with our growing portfolio of patents covering ultra-low emission plant designs will accelerate the adoption of the Grannus Process throughout the industry.”
Grannus intends to finalise its licensing plans over the next 90 days that will to enable other H2 and ammonia projects to meet the new BACT requirements in their plant design. The company works with premier technology and equipment suppliers in the design and off-site fabrication of modular subsystems that will be assembled on-site. This construction strategy will reduce both construction time and cost as well as risk of cost overruns.
Grannus was formed in 2012 to develop and bring to market next generation ammonia fertiliser production process technology. Grannus’ patented processes replace the traditional autothermal or steam methane reformation with a more efficient process that creates synthesis gas at the lowest emissions level in the industry at efficiency levels exceeding existing best-of-class plant designs and the least water use. The company intends to increase plant capacity designs to “world-scale” and expand into adjacent markets including H2, methanol and other down-stream chemicals.
