U.S. Dairy Biogas Systems Have Doubled Since 2020

Coming off June Dairy Month, the American Biogas Council released new data on the continued growth of dairy-based biogas systems in the U.S.  According to the Council, the number of operational dairy biogas systems has more than doubled since 2020, with more than $53 billion invested in renewable energy and methane capture infrastructure.  As of June 2025, 471 dairy biogas systems are in operation.

Collectively, these operations capture over 144,000 cubic feet per minute of biogas.  That total is the equivalent of powering approximately 615,000 homes annually.  While the systems reduce methane emissions and create renewable energy, they also recycle the manure from about 2.3 million cows, producing natural fertilizer and animal bedding while reducing odors.  That’s about 15 billion gallons of manure put to beneficial use every year. 

ABC says these operations also eliminate almost one million tons of methane emissions each year. Also, an estimated 2,980 additional dairies are still eligible for biogas development.

Here in the Northwest, 49 systems are on-line in Washington, 48 are operational in Oregon, while Idaho has 32 systems up and running.  For a state by state breakdown o the systems on-line, as well as potential systems into the future, Click Here.
