Demonstrative Project for Generating Greenhouse Gas Emission-Free Electricity from Fossil Fuel -2009
One of the greatest technological challenges of the energy sector is to achieve a reduction of CO2 emissions produced by electric power plants. CO2 is also a widely used product in the oil industry to improve extraction. We propose the execution of a demonstrative project in the Gulf of Mexico between the national companies PEMEX and the Federal Electricity Commission (CFE), where a portion of the CO2 present in emissions from a CFE power plant would be captured; subsequently, it would be pressurized and transferred to a PEMEX depleted field where it would be injected to stimulate oil production (EOR for its acronym in English). We evaluated different technological options for electricity generation from a technical, economic and environment point of view, having carbon and/or petroleum coke as fuels. The option which had the lowest cost of electricity generation was the option of coal-red power stations with a circulating fluidized bed with petroleum coke as fuel, in which the unit cost of investment is 4,098 USD/kW and a level cost of 135 USD/MWh. However, if the economic benefit is incorporated from the sale of oil barrels obtained by the injection of CO2, as well as the benefit obtained by the environment externalities, the level cost obtained is reduced to 17 USD/MWh.
