New environmental efficiency knowledge show that Qnergy’s PowerGen system is the primary generator to allow 100% methane destruction. This Free Piston Stirling Engine (FPSE) demonstrates superior environmental efficiency, exceeding Environmental Safety Company (EPA) tips by orders of magnitude, in response to impartial third-party testing. The outcomes present that, for the primary time, environmentally-friendly, utility-grade electrical energy will be sourced from methane technology on the website, utilizing a generator with zero methane slip. The confirmed system is already in use on greater than 1000 websites throughout the Americas, the place it has delivered greater than 15 million hours of dependable energy, with a maintenance-free engine.
Qnergy’s PowerGen expertise relies on an exterior combustion engine, with a clean-burning exterior combustor designed to work with any gaseous gasoline. It makes use of energy electronics and software program to regulate for variable uncooked supply gasoline feedstocks. Third-party researchers examined the efficiency of the PowerGen, discovering that combustion resulted in >99.998% (~100%) methane destruction effectivity, with particulate matter, carbon monoxide, and nitrogen oxide emissions ranges at 0.11, 0.30, and 1.1 g/kWh, respectively, that meet and exceed EPA emission standards.
Methane is a potent greenhouse gasoline, with 84 instances the worldwide warming potential of carbon dioxide over its first 20 years when allowed to flee into the environment. The productive use of methane waste is a world problem, given the numerous distributed sources, from upstream nicely pads within the vitality business to farms and natural waste websites. These numerous methane sources all require energy to seize, retailer, and/or convert methane into helpful vitality.
Traditionally, services that emit methane have been unable to make use of uncooked gasoline methane as a gasoline, because of the challenges of corrosive contaminants, fluctuations in move, and purity. Typical turbines based mostly on inner combustion engines carry out poorly, requiring common upkeep and struggling ongoing corrosion and excessive working prices. As well as, these typical engines don’t totally combust methane, resulting in methane slip, or discharge to the environment.
“Addressing and mitigating distributed methane sources is a key pillar in curbing local weather change,” mentioned Ory Zik, CEO of Qnergy. “The issue is that methane manufacturing is distributed throughout so many websites and that the power to seize and stop emissions at these websites requires energy. Utilizing the uncooked gasoline itself to generate utility-grade electrical energy for native use is a perfect answer, however provided that the generator will be assured to emit close to zero methane missions.
“This analysis demonstrates how the seize and conversion of methane generally is a excellent detrimental emissions supply – turning a dangerous greenhouse gasoline into ultra-low emission vitality.” added Zik.
These outcomes corroborate earlier third-party testing carried out by the Canadian Emissions Discount Innovation Middle (CanERIC), which additionally licensed the PowerGen as the one generator examined to attain 100% methane destruction.
