CAGE has developed a suite of gas engine control and combustion technologies. CAGE technology marries precise control with optimized engine systems to minimize emissions and improve efficiency and performance. CAGE engines provide a plug-and-play solution for biogas produced from anaerobic digestion and residual landfill gas. Easy to install and simple to use, CAGE generator runs on raw biogas with 45% or higher levels of methane, requiring no methanation system. CAGE generator is a perfect economic solution for small-scale local use of biogas with similar performance to equivalent-size diesel engines.
