NETL Fischer-Tropsch Black Box Model

Date: 9/15/2015
Contact: Timothy J. Skone, P.E.

The purpose of the Fischer-Tropsch (F-T) Black Box Model is to allow for the screening of the impacts of F-T finished fuels production based on the input of a unique syngas composition. Utilizing the composition of the raw syngas, the model calculates the following outputs based on a facility sized to produce 50,000 bbl/day of liquid product: CO2 emissions, liquid product flows, required syngas input, and the net export electricity from the facility. NETL completed this model/study for the Connecticut Center for Advanced Technology (CCAT) to provide techno-economic and life cycle analysis modeling support for CBTL alternative jet fuel production, which forms key references to their report to the Defense Logistics Agency (their project sponsor/funder).


Coal and Biomass to Liquids (CBTL) Greenhouse Gas Optimization Tool Documentation

Date: 3/11/2015
Contact: Timothy J. Skone, P.E.

This report is the user documentation for the NETL CBTL Jet Fuel Model submitted under a separate approval routing. The documentation is intended to accompany the model. The documentation explains how to the use the model. The documentation does not contain any energy analysis findings. NETL completed this model/report as part of a study for the Connecticut Center for Advanced Technology (CCAT) to provide techno-economic and life cycle analysis modeling support for CBTL alternative jet fuel production, which forms key references to their report to the Defense Logistics Agency (their project sponsor/funder).


Coal and Biomass to Liquids (CBTL) Greenhouse Gas Optimization Tool

Date: 3/11/2015
Contact: Timothy J. Skone, P.E.

The purpose of the model is to perform scenario analysis to optimize GHG performance under varies CBTL configurations.  This model expands upon the NETL CBTL Jet Fuel Model by providing the user the ability to choose from three coal types (Illinois No. 6 bituminous coal, Montana Rosebud sub-bituminous coal, or North Dakota Lignite) and three biomass types (Southern pine, switchgrass, or municipal solid waste). The model will also allow the user to adjust the fraction of the captured CO2 that is vented and adjust the overall efficiency of the plant.  The model includes environmental performance data for CBTL plants modeled under the CCAT case studies and two additional NETL studies: Production of Zero Sulfur Diesel Fuel from Domestic Coal: Configurational Options to Reduce Environmental Impact and Cost and Performance Baseline for Fossil Energy Plants Volume 4: Coal-to-Liquids via Fischer-Tropsch Synthesis.


CBTL Jet Fuel Model

Date: 2/27/2015
Contact: Timothy J. Skone, P.E.

An Excel-based model was developed to allow in-depth user access to the technological process, economic, and life cycle environmental results that were completed in support of this study, for each of the different CBTL jet fuel production scenarios (total of 49 unique result sets when counting both TRIG and EFG scenarios). The CBTL Jet Fuel Model incorporates a stochastic analysis of modeled results, drawing on input statistical distributions for the 17 environmental and 40 economic parameters. A stochastic analysis was performed by using the Palisade Corporation’s @RISK Excel add-in. NETL completed a CRADA with Connecticut Center for Advanced Technology (CCAT) to provide techno-economic and life cycle analysis modeling support for CBTL alternative jet fuel production, which forms key references to their report to the Defense Logistics Agency (their project sponsor/funder).


Grid Mix Explorer (Model)

Date: 1/28/2015
Contact: Timothy J. Skone, P.E.

The goal of the Grid Mix Explorer is to allow the user to customize the makeup of their electricity grid specific to their life cycle case or desired scenario, and to generate a life cycle inventory for that particular mix of technologies.


Power Plant Flexible Model

Date: 11/8/2013
Contact: Timothy J. Skone, P.E.

The Power Plant Flexible Model (PPFM) is an Excel-based tool that simulates coal combustion-based power plant electrical output, emissions, materials usage, and costs for a fully-configurable mix of boiler and steam plant types, feedstocks, and emissions control equipment. The technical documentation and user's guide for the model are included in the download package. PPFM is not engineered to be a consumer-level product and requires knowledge of coal combustion power plants and processes to yield reasonable results.


Power Systems Life Cycle Analysis Tool (Model)

Date: 6/1/2013
Contact: Justin Adder

The Power Systems Life Cycle Analysis Tool (Power LCAT) is a high-level dynamic model that calculates production costs and tracks environmental performance for a range of electricity generation technologies: natural gas combined cycle (NGCC), integrated gasification combined cycle (IGCC), supercritical pulverized coal (SCPC), existing pulverized coal (EXPC), nuclear, and wind (with and without backup power). All of the fossil fuel technologies also include the option of carbon capture and sequestration technologies (CCS). The model allows for quick sensitivity analysis on key technical and financial assumptions, such as: capital, O&M, and fuel costs; interest rates; construction time; heat rates; taxes; depreciation; and capacity factors. Power LCAT is targeted at helping policy makers, students, and interested stakeholders understand the economic and environmental tradeoffs associated with various electricity production options.


Calculating Uncertainty in Biomass Emissions Model, Version 2.0 (CUBE 2.0): Model and Documentation

Date: 11/15/2011
Contact: Timothy J. Skone, P.E.

CUBE 2.0 was designed to facilitate examination of the sources and magnitude of uncertainties in GHG emissions resulting from cultivation, preparation, and delivery of biomass feedstocks and to allow exploration of the sensitivity of net emissions to these various uncertainties. Included are emissions associated with corn grain, corn stover, switchgrass, mixed prairie biomass, and hybrid poplar and two biomass residues: forest residue and mill residue. This model is an update to the CUBE 1.0 model released in March 2010.


Life Cycle Greenhouse Gas Analysis of Advanced Jet Propulsion Fuels: Fischer Tropsch Based SPK-1 Case Study (Model)

Date: 9/1/2011
Contact: Timothy J. Skone, P.E.

In response to the Energy Independence and Security Act (EISA), NETL conducted an LCA of 10 fuel production pathways using Fischer-Tropsch synthesis. These pathways use varying combinations of coal and swithgrass feedstocks and two options for carbon management (sequestration or enhanced oil recovery). Only greenhouse gas (GHG) emissions are inventoried. Comparative analysis of the results demonstrate that higher percentages of biomass result in lower life cycle GHG emissions when using switchgrass. The choice of carbon management strategy has an effect on the results.


NETL Upstream Dashboard Tool

Date: 8/1/2011
Contact: Timothy J. Skone, P.E.

The goal of the Upstream Tool is to allow the user to customize key parameters specific to their Life Cycle case study or desired scenario, and generate customized Upstream Emissions results quickly and simply.


CBTL Jet Fuel Model

Date: 2/16/2011
Contact: Timothy J. Skone, P.E.

The Connecticut Center for Advanced Technology (CCAT) has received funding from the Defense Logistics Agency (DLA) Energy to demonstrate how liquid fuel can be produced from coal and meet the Energy Independence and Security Act (EISA) of 2007 greenhouse gas (GHG) requirement for DOD fuel purchases of synthetic fuel. Section 526 of EISA requires that any fuel purchases have a life-cycle CO2 emission less than conventional petroleum fuel. This model evaluates different scenarios for the conversion of coal and biomass to jet fuel using oxygen blown, transport reactor integrated gasifier and Fischer-Tropsch catalyst configurations.
