Promus Renewable Natural Gas (RNG) Projects
Promus Outlook Granger Project (Operational)
The Promus Outlook Granger (POG) Project converts organic waste from roughly 5,500 dairy cows into over 900,000 gasoline gallon equivalents per year of pipeline quality renewable natural gas (RNG), bio-fertilizers, and fiber products. Because the project reduces greenhouse gas emissions (primarily methane), it has an ultra-low carbon intensity score (-240 gCO2e/MJ) and generates high-value marketable environmental attributes (in particular, state low carbon fuels standard credits and federal renewable fuel credits), as well as revenue from commodity energy sales.
The RNG is transported through a dedicated project pipeline and interconnect facility, where it is injected into the existing interstate pipeline grid for use by natural gas vehicles – transit busses, delivery vans, airport shuttles, garbage trucks — in West Coast states with clean fuels programs (CA, OR, WA).
Promus Biogas to Electricity (EV) Projects
Following Promus’ successful development and operation of the Promus Outlook Granger project, Promus has contracted with multiple dairies listed below to build and operate additional dairy digester-based projects across West Coast States. To position itself on the leading edge of the transportation sectors transition to the widespread adoption of electric vehicles, Promus has broadened its focus towards also developing biogas to electricity for electric vehicles projects. Rather than upgrading biogas to pipeline quality natural gas, many of Promus’ next projects will instead run biogas through either a combustion generator or a fuel cell and export the electricity to the grid. The addition of electricity projects allows Promus to work with dairies previously deemed too small for an RNG project and ensures long-term market access in low carbon fuels markets.
