FlexEnergy Capturing the Low Btu Gas Market Available to No One Else! www.flexenergy.com Edan Prabhu, Founder Tom Smith, CEO

FlexEnergy: 

FlexEnergy The Flex-Microturbine (“Flex”) is the only ultra-low Btu power plant that can use fuel with a concentration level as low as 15Btu/scf - pipeline gas is 1,000 Btu/scf Low Btu gas is a costly problem for industry - the Flex turns this into a revenue opportunity Reduces NOx and carbon footprint - NOx below .1 ppm or one tenth of any other system Low Btu fuel is a multi-billion dollar untapped market opportunity
