Our Investment Portfolio

Clean Energy Systems (CES) * has developed an oxy-fuel combustion technology to generate electric power with zero or near-zero NOx, SOx, toxins or greenhouse gas emissions. Fuels include both gaseous fuels such as natural gas, syngas from coal, biomass or landfill gas biodigester gases and liquid fuels including glycerin from bio-diesel production facilities, refinery residues and oil-water emulsions. Using pure oxygen to burn hydrocarbon fuels produces tremendous amounts of heat energy, and only CO₂ and water as byproducts. If this exhaust stream is used to turn a steam turbine and then the CO₂ is injected deep into underground sandstone formations, there is no pollution and no CO₂ emissions.
