Project Description

TDA Research, Inc. (TDA) is demonstrating the technical and economic viability of a new Integrated Gasification Combined Cycle (IGCC) power plant designed to efficiently process low-rank coals. The plant uses an integrated carbon dioxide (CO2) scrubber/water gas shift (WGS) catalyst to capture more than 90 percent of the CO2 emissions, while increasing the cost of electricity by less than 10 percent compared to a plant with no carbon capture.
TDA is optimizing the sorbent/catalyst and process design, and assessing the efficacy of the integrated WGS catalyst/CO2 capture system, first in bench-scale experiments and then in a slipstream field demonstration using actual coal-derived synthesis gas. The results will feed into a techno-economic analysis to estimate the impact of the WGS catalyst/CO2 capture system on the thermal efficiency of the plant and the cost of electricity.

Project Benefits

Gasification of coal or other solid feedstocks (wood waste, petroleum coke, etc.) is a clean way to produce electricity and produce or co-produce a variety of commercial products. The major challenge is cost reduction; current integrated gasification combined cycle (IGCC) technology is estimated to produce power at a cost higher than that of pulverized coal combustion. However, the Gasification Program is supporting research and development (R&D) to develop technologies with the potential to produce electric power with greater than 90 percent carbon capture at a cost of electricity (COE) that will be lower than the COE of any other coal-fueled power generation technology with carbon capture. The public benefits of the Gasification Program are significant—lower cost power, cleaner environment, reduced carbon footprint, less water use, reduced dependence on imports, increased U.S. technological competitiveness, and high-value U.S. jobs.

Approximately 50 percent of the coal produced in the United States is low-rank coal (sub-bituminous coal and lignite). Low-rank coal has less energy per pound than higher-ranked eastern (bituminous) coal, but costs much less. In alignment with Department of Energy (DOE) Gasification Program goals, the National Energy Technology Laboratory (NETL) is partnering with TDA Research, Inc. (TDA) to demonstrate the technical and economic viability of a new IGCC power plant designed to efficiently process low rank coals

The successful development of advanced technologies and innovative concepts that reduce emissions of CO2 into the atmosphere is a key objective to help mitigate the effects of climate change. The project will promote the commercialization of low-ranked coal-based IGCC with carbon capture by advancing technologies to make the process more economical. The project supports the DOE’s goal of using gasification to provide power from coal with 90 percent carbon capture, utilization, and storage at minimal increase in the cost of electricity. DOE is developing advanced technologies to ensure the nation’s abundant energy resource can be used in a manner that strengthens the economy and protects the environment.
