TDA RESEARCH, INC. — Department of Energy SBIR Phase I: 18d

Description

The electricity produced from fossil fuels is essential to the world’s prosperity and security, but the increasing atmospheric CO2 concentrations caused by the fossil fuel combustion are implicated in global warming. Although there are several methods for separating CO2 from the flue gases, all of them have significant drawbacks, including loss of efficiency and increased capital and operating costs that dramatically increase the cost of electricity. TDA Research, Inc. (TDA) proposes to develop a new class of sorbents to remove CO2 selectively and with high capacity from the flue gases generated from pulverized-coal combustion power plants. The new adsorbent will tolerate moisture and work effectively at a wide range of CO2 concentrations. In Phase I we will prepare various sorbent formulations and screen them to determine their capacity to adsorb CO2 under representative conditions. Based on the performance results, we will carry out a preliminary design of our CO2 capture system, estimate its size and cost, and carry out an engineering assessment to compare it to alternative processes.
