May 2, 2025. The American biogas industry is entering a historic growth phase, fueled by surging demand for reliable energy, the need to reduce waste, and a massive pipeline of untapped development opportunities across all 50 states, according to new data released by the American Biogas Council (ABC) at its annual BIOGAS AMERICAS trade show and conference.
The numbers – which tally potential biogas projects in each state and represent the most comprehensive collection to date – show that with nearly 2,500 operational biogas systems already in place and an estimated 17,000 additional projects ready for deployment, the U.S. stands on the brink of a transformation where food waste, sewage, manure and other organics are optimized for clean energy.
Last year, 125 new projects came online, totaling $3 billion in capital expenditures.
“Biogas is no longer a niche technology – it’s spreading economic growth nationwide across the energy, waste and agriculture sectors,” ABC Executive Director Patrick Serfass said at the conference, held this year in Denver. “We’re seeing record investment and record momentum, and we’re just getting started.”
Despite this progress – and biogas systems operating in all 50 states – the U.S. has only scratched the surface of its biogas potential. Just 14.7% of all potential biogas facilities have been built.
Additionally, the ABC highlighted new polling data at BIOGAS AMERICAS that demonstrates broad interest by American voters in energy solutions that reduce waste and produce reliable, renewable power among a variety of national issues.
The industry’s momentum was on display at this year’s conference, which featured 350 exhibits, 2,200 participants, breaking attendance records for the fourth year in a row.
