Demonstrative Project for Generating Greenhouse Gas Emission-Free Electricity from Fossil Fuel -2009

2009

Abstract

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 benefit is incorporated from the sale of oil barrels obtained by the injection of CO2, as well as the benefit obtained by the environment externalities, the level cost obtained is reduced to 17 USD/MWh.
