Techno-economic Evaluation of Utility-Scale Power Plants Based on the Indirect sCO<sub>2</sub> Brayton Cycle - Report

Charles White Walter Shelton Nathan Weiland Travis Shultz John Plunkett

This report presents the results of a techno-economic analysis (TEA) of a coal-fired utility scale power plant based on the indirect supercritical carbon dioxide (sCO2) Brayton cycle using an oxy-fired circulating fluidized bed (CFB). A baseline plant configuration was examined as well as three variations to the sCO2 power cycle examining the impact of reheat (Rht), main compressor intercooling (IC), and a combination of reheat and main compressor intercooling (RhtIC). Each plant configuration was assessed at two turbine inlet temperatures of 620 °C and 760 °C.

Performance and Cost Potential for Exemplar Direct Supercritical Carbon Dioxide Natural Gas Plants

Sandeep Pidaparti Charles White Selcuk Can Uysal Eric Liese Nathan Weiland

This report presents the techno-economic analysis (TEA) optimization results of natural gas-fired utility-scale power plants based on the direct supercritical carbon dioxide (sCO2) power cycle. To identify optimum plant configuration, the study also considered three different cases (Case A, Case B, Case C) with varying levels of thermal integration with the plant air separation unit (ASU). A fourth case (Case D), which is based on a patent from 8 Rivers, was also considered and includes thermal integration with the ASU as well as compressed recycle carbon dioxide (CO2) gas. The four direct sCO2 power plants offered similar or slightly higher plant efficiencies than the reference NGCC plants based on an F-class gas turbine with carbon capture and storage (CCS). LCOE of the direct sCO2 plants is 13.5–17.2 percent higher than the reference NGCC plants with CCS due to higher capital costs associated with the ASU and sCO2 power block. Recuperators make up over 50 percent of the power cycle costs. Consequently, any research and development (R&D) efforts to reduce the recuperator capital costs will be beneficial for the technology commercialization. The study also investigated the impact of co-firing landfill gas (LFG) and natural gas on plant efficiency, LCOE, and CO2 emissions. Increasing the LFG co-firing from 0 percent to 50 percent (mass basis), decreased the plant efficiency by 0.3 percentage points and increased the LCOE by 3 percent. Due to high inherent CO2 capture rates, direct sCO2 plants have strong potential to achieve net-zero CO2 emissions with LFG and natural gas co-firing.

Supercritical Carbon Dioxide (SCO<sub>2</sub>) Cycle as an Efficiency Improvement Opportunity for Air-fired Coal Combustion

Walter Shelton Nathan Weiland Travis Shultz Charles White

Coal has been historically the fuel to satisfy the United States' need for baseload electricity generation. Increasingly stringent environmental regulations (specifically uncertainty for CO2 emission regulations), are forcing the electric power industry to scrutinize the long-term viability of new and existing coal-fueled assets. The development of advanced, higher efficiency coal power generation technologies leading to reductions in CO2 and other emissions and competitive costs are one avenue to address these concerns. A goal of this study was initially to identify one or more conceptual designs for a coal-fired power plant that could meet the existing "Carbon Pollution Standard (CPS) for New Power Plants" without dedicated CO2 capture equipment. Since the EPA proposals are still under the review process, this report uses the current limits. Additional goals include: sCO2 cycles systems that achievie an efficiency > 46.7 % HHV and a cost of electricity of < $82.3/MWh.

Two Physically Different Neutron Beta-Decay Half-Life Calculations are in Exact Agreement with the NIST Beam Experiment

Wayne A. Surdoval David Berry Travis Shultz A. L. Ferreira

This paper presents two calculations of the free-neutron lifetime. The calculations reflect two distinct physical viewpoints, and both are in exact agreement with each other, and within reported significant figures, in exact agreement with the NIST Beam Experiment measurement of the neutron lifetime (887.7 (+/- 3.1) seconds (615.3 second half-life)). Both calculations are a priori requiring no arbitrary parameters. CODATA 2018 values used for physical constants. Currently the 'beam' method and the 'magnetic bottle/trap' method are the two primary experiments for determining neutron lifetime. Given the error bands, the results of the experiments are not in agreement. It is considered a significant objective to bring the measurements into agreement or provide a theoretical explanation of why they are different. This paper presents results of two calculations based on different physical origins.The half-life result of both calculations are in exact agreement with the 'beam' experiment.

Cost and Performance Baseline for Fossil Energy Plants Volume 1: Bituminous Coal and Natural Gas to Electricity

Tommy Schmitt Sarah Leptinsky Marc Turner Alexander Zoelle Charles White

This revised report presents an independent assessment of the cost and performance of select fossil energy power systems - integrated gasification combined cycle (IGCC), pulverized coal (PC), and natural gas combined cycle (NGCC) plants - using a systematic, transparent technical and economic approach. The cost and performance of fossil fuel-based generation technologies represented in this report (and the series at large) are important inputs to assessments and determinations of technology combinations to be utilized to meet the projected demands of future power markets. In addition to informing technology comparisons, the reference plant configurations found in this report provide perspective for regulators and policy makers. From a research & development perspective, this report is used to assess goals and metrics and to provide a consistent basis for comparing developing technologies.

Bituminous Coal and Natural Gas to Electricity: >90% Capture Cases Technical Note

Tommy Schmitt Alex Zoelle Sally Homsy Timothy Fout Travis Shultz

This technical note provides cost and performance estimates for post combustion carbon capture (PCCC) systems designed for greater than 90 percent capture on conventional PC- and NG-fueled power plants. The cost and performance estimates provided here were developed using the National Energy Technology Laboratory’s (NETL’s) well-documented methodology for conducting technoeconomic analysis of fossil energy conversion systems and leveraging published performance and cost projections for higher capture rate systems. Included in this technical note is a brief description of the method used to adjust select 90 percent capture cases from NETL’s Cost and Performance Baselines for Fossil Energy Systems Volume 1: Bituminous Coal and Natural Gas to Electricity, hereafter referred to as the Baseline Study. This technical note is intended to serve as an interim update to NETL’s Baseline Study cases by providing cost and performance estimates for high capture PCCC technology that can be deployed in the near-term at fossil-fueled electricity generating units.
