FlexEnergy Tackles Military Landfill Gases

FlexEnergy recently revealed that two of their newly developed Powerstation generators will soon go to work converting the gases from the U.S. Department of Defense’s (DOD) landfill at Fort Benning, GA into clean, renewable energy. The plan is part of the DOD’s ESTCP (Environmental Security Technology Certification Program) and, by working with the SRI (Southern Research Institute) the DOD and FlexEnergy expect the installation will provide some valuable information about the greater potential and scalability of the new device.

The Flex Powerstation is a generator that works by converting gas into electricity. What reportedly makes it special is its ability to effectively oxidize air with extremely low percentages of gases and efficiently produce electricity while keeping emissions down to less than 1 ppm.

FlexEnergy says that the Powerstation can reportedly utilize methane percentages as low as 1.5% and, unlike conventional gas power generators, doesn’t require fuel cleaning and moisture removal processes that consume as much as 20% of the energy that gets produced. Those attributes look to make it what seems an ideal candidate for locations such as landfills, where methane percentages are generally dilute and inconsistent.

FlexEnergy is currently running a pilot program at the Lamb Canyon Landfill in Riverside County, California. There, a smaller 10-ton Powerstation is already generating enough electricity to power about 30 homes. The much larger Georgia 250 kW installation, said the company, could potentially provide power for up to 250 homes. If the new DOD  landfill power plant is successful, it could mean our waste will no longer go completely to waste and, instead, become a viable renewable energy source. It will also put a big dent in the 300 million tons of methane gas that seep into our atmosphere each year.
