Adoption of anaerobic digestion (AD) of dairy manure has grown in New York state and across the U.S. in recent years, driven primarily by strong market value for use of biogas as transportation fuel under national and state-level fuel standards (e.g., California’s Low Carbon Fuel Standard and Oregon’s Clean Fuels Program). Cornell CALS PRO-DAIRY estimates that over 15 million gallons of diesel consumption is reduced per year from the currently operating dairy manure AD systems in NY that provide biomethane , also known as renewable natural gas (RNG). Additional on-farm AD systems in NY are generating approximately 38 million kWh of electricity per year, equivalent to over 30 MW of solar PV capacity. While the recent growth has predominantly occurred on dairy farms with more than 2,000 milking cows, technology is widely available to scale down AD for even the smallest dairy operations . The challenge in successful adoption then lies in the economic feasibility and practical consideration of the impacts to the farm operations.
