Feasibility Studies to Improve Plant Availability and Reduce Total Installed Cost in IGCC Plants

Project Description

General Electric (GE) sees opportunity in the global trend for cleaner power production using its IGCC technology. The company believes that power can be economically and cleanly produced from coal through the use of its technologies and desires to utilize its coal gasification and power generation technology expertise to meet this goal. The objective of this 3-year project is to evaluate potential improvement in total installed cost and availability through deployment of a multi-faceted approach encompassing technology evaluation, constructability assessment, and design methodology. Eastman Chemical Company is supporting the GE effort by providing consulting on the evaluation and technology transfer phases of the project. The end result is to reduce the time to technological maturity and enable plants to reach higher values of availability in a shorter period of time at a lower installed cost.


Program Background and Project Benefits

Gasification is used to convert a solid feedstock, such as coal, petcoke, or biomass, into a gaseous form, referred to as synthesis gas or syngas, which is primarily hydrogen and carbon monoxide. With gasification-based technologies, pollutants can be captured and disposed of or converted to useful products. Gasification can generate clean power by adding steam to the syngas in a water-gas-shift reactor to convert the carbon monoxide to carbon dioxide (CO2) and to produce additional hydrogen. The hydrogen and CO2 are separated—the hydrogen is used to make power and the CO2 is sent to storage, converted to useful products or used for EOR. In addition to efficiently producing electric power, a wide range of transportation fuels and chemicals can be produced from the cleaned syngas, thereby providing the flexibility needed to capitalize on the changing economic market. As a result, gasification provides a flexible technology option for using domestically available resources while meeting future environmental emission standards. Polygeneration plants that produce multiple products are uniquely possible with gasification technologies. The Gasification Systems program is developing technologies in three key areas to reduce the cost and increase the efficiency of producing syngas: (1) Feed Systems, (2) Gasifier Optimization and Plant Supporting Systems, and (3) Syngas Processing Systems.

Gasifier Optimization and Plant Supporting System technologies under development are targeted at increasing gasifier availability and efficiency, improving performance, and reducing the capital and operating costs of advanced gasification plants. Ongoing R&D projects are developing more durable refractory materials, creating models to better understand the kinetics and particulate behavior of fuel inside a gasifier, and developing practical solutions to mitigate the plugging and fouling of syngas coolers. Future work will focus on the development of cutting edge gasifier technologies, which will start with multiple competing concepts and continue with support of the most aggressive and successful technologies being developed, both in the Gasification Systems program and other DOE programs, to reduce the cost of coal gasification. Future work will also aim to reduce the amount of water used in gasification plants and integrate technologies throughout the plant and beyond in a holistic approach to increase efficiency and reduce costs (e.g., the optimization of gasification plants to sell CO2 for EOR applications).

This General Electric Company project focuses on studying the feasibility of improving plant availability and reducing total installed costs in integrated gasification combined cycle (IGCC) plants, by developing and improving operating methodologies, simulations, and control philosophies. The project targets reducing the time to technological maturity and enabling plants to 90 percent availability in a shorter period of time and at a lower installed cost. Specifically, this project will develop techno-economic studies using cost and availability data.


Project Scope and Technology Readiness Level

In this project, GE will perform techno-economic studies on its IGCC technology focused on cost and/or availability criteria. The scope of work includes the identification of system- and component-level requirements for each task and subtask; the development of designs and materials as required for technical evaluation of concepts, validation, and testing of components/sub-systems; and the development of appropriate operating methodologies, simulations, and control philosophies where applicable.

The Technology Readiness Level (TRL) assessment identifies the current state of readiness of the key technologies being developed under the DOE’s Clean Coal Research Program. In FY 12, this project was assessed a TRL of 2.

The TRL assessment process and its results including definition and description of the levels may be found in the "2012 Technology Readiness Assessment-Analysis of Active Research Portfolio".
