Wastewater Feed for Fuel for Near Zero Engine Vehicles
California’s South Coast Air Quality Management District has moved closer to supporting a $25.5 million Kore Infrastructure project to produce RNG/renewable natural gas from municipal waste-derived biomethane – and use it to power vehicles with the new Near Zero variant of the 8.9-liter Cummins Westport ISL G engine.
SCAQMD proposes to ante $1 million, plus $1.5 million from the BP Arco Settlement Projects Fund, in support of the project in Rialto, immediately west of San Bernardino. Kore’s share is $23 million.
“Kore Infrastructure is proposing to construct a new full-scale modular biomethane production facility in Rialto, using a proprietary process developed and demonstrated over a six-year period at a local wastewater plant,” AQMD says.
‘A Fully Integrated System’ for RNG Production
“The proposed facility will utilize a fully integrated system to process biosolids into RNG, utilizing biosolids from local wastewater agencies and converting the energy into RNG that can be used locally as transportation fuel in the next generation natural gas engines that are certified to achieve 90% lower NOx emissions than the existing 2010 heavy-duty engine exhaust emissions standard.”
Kore has a patented five-state process, the agency notes, consisting of material handling, drying, pyrolysis, pyrolysis gas conversion to RNG, and compression.
Cummins Westport ISL G NZ
SCAQMD and partner agencies are already backing the placement of transit and refuse vehicles with the Cummins Westport ISL G NZ (F&F, May 13), and shortly after the engine’s certification was announced last year moved to support development of a Near Zero variant of the 11.9-liter ISX12 G (F&F, October 13, 2015).
Advantages of the Near Zero-biomethane combination of combination have been detailed by Fleets & Fuels publisher Gladstein, Neandross & Associates in a 192-page white paper dubbed Game Changer (F&F, May 10). SCAQMD helped fund GNA’s Game Changer initiative, as did the Southern California Gas and Pacific Gas and Electric utilities, the California Natural Gas Vehicle Partnership, the American Gas Association, Agility Fuel Systems and Clean Energy Fuels.
