Bloom Energy to transform waste into clean community electricity

In the US, The Fayetteville Public Works Commission (PWC) and Bloom Energy, which is a leading distributed energy company, have announced plans to install and operate 1.5 megawatts of solid oxide fuel cells. Creating renewable energy from multiple biogas streams in the region, the new project will reduce emissions and advance the Fayetteville community’s efforts to meet North Carolina’s clean energy standards.

Bloom Energy’s fuel cells combine ambient air with fuel, such as biogas, to create electricity without combustion. Generating power from multiple biogas streams, the fuel cell installation – to be located adjacent to PWC’s P.O. Hoffer Water Treatment Facility – will be one of the first of its kind to blend multiple waste gas sources to produce clean, carbon-neutral electricity. The project will use biogas captured from PWC’s Cross Creak Water Reclamation facility, an adjacent landfill, and methane gases captured from local and neighboring swine farms.

As nations and cities continue to grow and urbanize, waste generation is expected to increase by 70 percent by 2050. Currently, waste gas generated from the wastewater treatment process and landfills is flared, a commonly used and controlled method for releasing the gas into the atmosphere, which contributes to air pollution. By reducing biogas flaring at the wastewater and landfill facilities, local emissions are averted, helping to improve air quality. The project will also use methane -- a potent greenhouse gas that accounts for 50 to 70 percent of biogas – from swine farms that would otherwise be released into the atmosphere.

By utilising multiple biogas streams, the waste-to-electricity project will provide reliable, always-on, and carbon-neutral electricity to meet the power demands equivalent to more than 1,000 homes. Bloom Energy’s fuel cells will complement PWC’s existing renewable energy sources, helping meet PWC’s North Carolina Renewable Energy and Energy Efficiency Portfolio Standard requirements.

“PWC is excited to collaborate with Bloom Energy to bring a first-of-its kind clean energy project to our community to serve our customers,” said Elaina Ball, CEO and general manager, PWC. “This project is an anchor for the broader plan to remediate and establish a Cleanfields Renewable Energy Demonstration Park in the community.”

“Producing resilient and renewable energy from waste sources is a critical component of decarbonized and sustainable circular economy,” added Chuck Moesta, vice president, gas management, Bloom Energy. “Our waste-to-energy solutions are garnering increasing interest from communities and municipalities. We look forward to bringing this innovative project alive with Fayetteville's municipal utility, setting an important example for other communities around the U.S. wishing to transition to clean, carbon-neutral energy.”
