OPAL Fuels Welcomes Congressman Eugene Vindman to Prince William County Renewable Natural Gas Facility

MANASSAS, Va.--(BUSINESS WIRE)--OPAL Fuels (Nasdaq: OPAL) a leading vertically integrated producer and distributor of renewable natural gas (RNG) welcomed Congressman Eugene Vindman (VA-07) to its RNG facility at the Prince William County Landfill in Manassas, Virginia. The visit included a tour of the facility and a meeting with OPAL Fuels Co-Chief Executive Officer Adam Comora to discuss the role of domestic RNG production in providing a cost-effective, lower-emissions alternative to diesel fuel that strengthens American energy security and supports economic growth in Northern Virginia.

“We were honored to host Congressman Vindman and show him firsthand how the Prince William RNG facility turns a local waste stream into homegrown American energy,” said Adam Comora, Co-Chief Executive Officer of OPAL Fuels. “Renewable natural gas strengthens our nation’s energy security, supports jobs and investment here in Northern Virginia, and gives heavy-duty fleets a proven, cost-effective way to cut emissions. Our partnership with Prince William County spans more than two decades, and this facility demonstrates the lasting impact that RNG can have on local communities and the nation's energy future.”

"The Prince William County RNG facility demonstrates how public-private collaboration can create economic, energy, and environmental value for local communities," said Congressman Eugene Vindman. "This facility puts a local resource to productive use while supporting American energy production and contributing to economic growth in Northern Virginia. I commend the OPAL Fuels and Prince William County teams for building a model partnership that is delivering tangible benefits for the community, the economy, and our energy future."

The Prince William RNG facility captures naturally occurring methane from the decomposition of organic waste at the Prince William County landfill and converts it into pipeline quality RNG that powers heavy-duty fleets across the country. Wholly owned by OPAL Fuels, the plant began commercial operations in 2024 and has a nameplate design capacity of approximately 1.7 million MMBtu, or roughly 12 million gasoline gallon equivalents (GGE), per year. Operating at approximately 92% efficiency, the facility refines gas that was previously combusted onsite into a usable clean fuel, cutting methane emissions at the landfill by approximately 95%.

The longstanding partnership between OPAL and Prince William County Landfill has delivered significant value through a shared commitment to operational excellence. The landfill’s best-in-class disposal practices, combined with OPAL’s enhanced wellfield management and optimization initiatives, have increased landfill-gas recovery by approximately 20% over the past year. OPAL believes there is additional opportunity for improvement over the coming months as optimization efforts continue. OPAL also extends its sincere thanks to the Prince William County team for its longstanding support and collaboration, which have been instrumental to the project’s success and continued performance gains.

In addition, the visit comes on the heels of Prince William County's first Environmental Sustainability Annual Report, released in April 2026 by the county's Office of Sustainability, which features the Prince William RNG facility as a case study in how long-term infrastructure investment and public-private partnership can advance the county's climate and air-quality goals. The facility captures methane that would otherwise be released or flared and converts it into a domestically produced fuel for heavy-duty transportation. According to the report, emissions of key pollutants at the landfill, including carbon monoxide, sulfur dioxide, nitrogen oxides and volatile organic compounds, have declined by more than 90% since the facility began operations, and methane emissions fell by more than half between 2023 and 2024. The report also notes that, according to the U.S. Environmental Protection Agency's landfill gas database, the Prince William facility is the only operating landfill-based RNG project in the Washington, D.C., metropolitan region.
