“…The net plant efficiency with CO 2 capture is between 23% and 26% (LHV) [53]. For retrofitting a higher efficiency supercritical PC plant, the energy penalty of CO 2 capture is much lower: the total energy output of the plant is reduced by about 20% and conditions are even more favorable for new supercritical PC plant with a net efficiency of about 34% (LHV) [54].…”

“…In new designs there is a possibility to place a larger part of the superheater into the furnace but for retrofit of existing plant the balancing would need to be done both by the control of the rate of flue gas recirculation and possibly also by shunting off excess steam before the superheater when necessary. The excess steam may be used in the ASU plant [54].…”

Electric power generation system development is reviewed with special attention to plant efficiency. It is generally understood that efficiency improvement that is consistent with high plant reliability and low cost of electricity is economically beneficial, but its effect upon reduction of all plant emissions without installation of additional environmental equipment, is less well appreciated. As CO 2 emission control is gaining increasing acceptance, efficiency improvement, as the only practical tool capable of reducing CO 2 emission from fossil fuel plant in the short term, has become a key concept for the choice of technology for new plant and upgrades of existing plant. Efficiency is also important for longer-term solutions of reducing CO 2 emission by carbon capture and sequestration (CCS); it is essential for the underlying plants to be highly efficient so as to mitigate the energy penalty of CCS technology application. Power generating options, including coal-fired Rankine cycle steam plants with advanced steam parameters, natural gas-fired gas turbine-steam, and coal gasification combined cycle plants are discussed and compared for their efficiency, cost and operational availability. Special attention is paid to the timeline of the various technologies for their development, demonstration and commercial availability for deployment. r

Liquid transportation fuels derived from coal and natural gas could help the United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal-and natural gas-based Fischer-Tropsch (FT) liquids, as well as to compare production costs. The results show that the use of coal-or natural gasbased FT liquids will likely lead to significant increases in greenhouse gas (GHG) emissions compared to petroleumbased fuels. In a best-case scenario, coal-or natural gas-based FT-liquids have emissions only comparable to petroleumbased fuels. In addition, the economic advantages of gas-toliquid (GTL) fuels are not obvious: there is a narrow range of petroleum and natural gas prices at which GTL fuels would be competitive with petroleum-based fuels. CTL fuels are generally cheaper than petroleum-based fuels. However, recent reports suggest there is uncertainty about the availability of economically viable coal resources in the United States. If the U.S. has a goal of increasing its energy security, and at the same time significantly reducing its GHG emissions, neither CTL nor GTL consumption seem a reasonable path to follow.

For CO 2 capture and storage deployment, the impact of impurities in the gas or dense phase CO 2 stream arising from fossil fuel power plants, or large scale industrial emitters, is of fundamental importance to the safe and economic transportation and storage of the captured CO 2 . This paper reviews the range and level of impurities expected from the main capture technologies used with fossil-fuelled power plants in addition to other CO 2 emission-intensive industries. Analysis is presented with respect to the range of impurities present in CO 2 streams captured using pre-combustion, post-combustion and oxy-fuel technologies, in addition to an assessment of the different parameters affecting the CO 2 mixture composition. This includes modes of operation of the power plant, and different technologies for the reduction and removal of problematic components such as water and acid gases (SO x / NO x ). A literature review of data demonstrates that the purity of CO 2 product gases from carbon capture sources is highly dependent upon the type of technology used. This paper also addresses the CO 2 purification technologies available for the removal of CO 2 impurities from raw oxy-fuel flue gas, such as Hg and noncondensable compounds. CO 2 purities of over 99 % are achievable using post-combustion capture technologies with low levels of the main impurities of N 2 , Ar and O 2 . However, CO 2 capture from oxy-fuel combustion and integrated gasification combined cycle power plants will need to take into consideration the removal of non-condensables, acid gas species, and other contaminants. The actual level of CO 2 purity required will be dictated by a combination of transport and storage requirements, and process economics.
