ZEST - Zero Emissions Steam Technology
Clean Energy Systems has developed and is advancing a superior power generation technology. The CES team - composed of the world's preeminent aerospace engineers, have developed a system that produces high energy steam that powers turbines to produce inexpensive electricity, with no emissions or pollutants.
The CES power system is based on the combustion of a clean fuel with oxygen in the presence of pure water in a unique steam generator that directly produces a non-polluting, high-temperature, high-pressure gas comprised of steam and carbon dioxide (CO2). The high-energy gases drive multi-stage turbines that, in turn, drive a generator to produce electricity. Exhaust gases from the turbine go to a condenser where gaseous CO2 is separated from liquid water. Most of the water is reheated and returned to the steam generator. The gaseous CO2 leaving the condenser passes to a recovery system where it is processed into marketable gaseous or liquid CO2. Any excess CO2 is economically compressed and cooled to a liquid or supercritical fluid for disposal by sequestration in the earth or ocean. There are no atmospheric emissions from the CES clean, green power system.
The clean fuel used in the CES system can come from virtually any source as long as it is composed almost entirely of the elements, carbon (C), hydrogen (H), and oxygen (O). The primary requirements for the fuel are that it is a fluid and essentially free of ash and elements such as sulfur (S) and nitrogen (N) that can form acid gases. Hydrocarbons such as methane, alcohols, hydrogen, and carbon monoxide are typical suitable fuels. Natural gas, petroleum, and gasified coal or biomass are all suitable fuel sources. Oxygen is used to combust the fuel rather than air as in conventional systems thereby eliminating the formation of NOX and the large volume of exhaust gas. The oxygen is obtained from air, typically in a cryogenic air separation plant.
CES' unique steam generator makes this advanced power system possible. The steam generator embodies numerous rocket-based materials and design features. It is an outgrowth of the knowledge of five company-founding engineers with almost 250 years of combined experience in the design, development, and testing of some of the world's most advanced liquid rocket propulsion systems. These features assure long life, precise and uniform mixing, careful thermal management, and provide residence times appropriate for important rate-limiting reactions to occur. Use of a clean fuel with oxygen negates the possibility of producing pollutants such as SOX and NOX. Proper choice of the fuel/oxygen mixture ratio (i.e., stoichiometric to H2O and CO2), complete mixing, and careful control of operating conditions (temperature, pressure, and residence time) virtually eliminate carbon containing pollutants (CO, VOC's, and particulates). The end result is a small gas generator that produces only steam and CO2 at virtually any desired, controlled temperature and pressure.
