:: CES Technology Meets Market Needs

CES technology satisfies needs in several market sectors, including: -
• Natural gas-fueled, zero-emission base-load and peaking electric power plants • Coal and biomass-fueled zero-emission power plants. • Enhanced fossil fuel recovery (oil, natural gas, coal-bed methane) from CO2 injection. • Re-powering of existing fossil fuel power plants to decrease atmospheric emissions. • Co-production of electricity and hydrogen from gasified solid fuel.

:: Electricity Generation

The U.S. Energy Information Administration forecasts the planned U.S. capacity additions from new generators from fossil based fuels will increase by 15,500 to 24,600 megawatts annually from 2007 through 2010 with a total of 76,500 megawatts needed during that four-year period. Global new capacity needs for the same four-year period are expected to be approximately 280,000 megawatts.

Peaking Power Generation

“Peaking power” is required on short notice to meet utility system demand during periods of high electricity demand. The CES technology is well-suited for small to medium sized peaking power plants. Its attributes are fast-start and low capital cost. Additional benefits can accrue by using the cold air emanating from a CES peaker plant as inlet air to co-located gas turbines or industrial air compressors.

Range of Power Plant Sizes

Future power generation is expected to be conducted at multi-hundred MW central power plants and at 50 – 100 MW distributed generation sites located closer to urban or industrial load centers. CES technology is scalable and can serve a wide range of size requirements. CES zero-emission technology will be easier to permit and will allow installation close to the locales of need.

:: Small Power Plants

Future power generation is expected to be conducted on a smaller scale, from distributed plants closer to the large urban or industrial load centers. CES zero-emission technology will be easier to permit and will allow installation close to the locale of need, where conventional power plant technologies would not be permitted.

:: Repower Existing Power Plants

CES technology can supplement or replace existing fossil-fueled boilers by generating steam for electricity generation. The CES-cycle reduces or eliminates atmospheric emissions including pollutants and carbon dioxide from conventional power plants.

:: Enhanced Hydrocarbon Recovery

For more than 40 years, CO2 has been injected into exhausted oil wells to increase oil production. This enhanced oil recovery (EOR) flooding process is in use at more than 40 oil fields domestically, and approximately four percent of the U.S. crude oil supply is produced from CO2 injected fields. The benefits from this flooding in the U.S. is estimated at 150,000 barrels per day. Extrapolating EOR to the entire U.S. oil production capacity, total CO2 needs are equivalent to the CO2 production from 90,000 megawatts of new gas fired power plants.

:: Non-Attainment Air Emission Regions

Very little new capacity is being constructed in large urban areas due to emissions constraints, and when combined with the bottleneck in transmission capacity, the net effect can result in local blackouts and high energy prices. The zero-emission aspect of CES technology allows power plants to be sited near load centers, with reduced transmission costs and losses.

Hydrogen and Electricity Co-Production

Gasification of solid fuels such as coal or biomass produces a synthetic fuel (syngas) containing both carbon monoxide and hydrogen. Hydrogen in the syngas can be separated and made available for fuel-cell or vehicle use. The resulting hydrogen-depleted syngas can be used in the CES oxy-fuel combustor to generate thermal energy or electricity.
