Mobile Propulsion and Fixed Power Production with Near-Zero Atmospheric Emissions

1. ABSTRACT: The US Military needs reliable, secure, and low-environmental impact sources of base and shore power for its installations. US Navy ships need generating systems for main propulsion, on-board power, catapults, heat/air conditioning, and other applications. These needs can be met with a unique, drive-gas generator that produces a high enthalpy mixture of high purity steam and carbon dioxide (CO2), with little or no nitrogen or sulfur oxides (NOx, SOx), volatile organic compounds (VOCs), or particulate material in the effluent. The steam mixture (5-10% CO2) exits the power cycle as pure water and readily captured CO2. This system can burn a wide range of fuels with oxygen, and is applicable for fixed and mobile applications. It could be used in fixed-base and shipboard power systems, or be incorporated into improved-efficiency steam power plants.
