Analysis of Natural Gas-to-Liquid Transportation Fuels via Fischer-Tropsch

Date: 09/2013

            Contact: Erik Shuster

This study models a GTL system that nominally produces 50,000 bbl/day of fuels fungible in the refined product infrastructure without further refining steps. Specifically, the system produces 15,460 bbl/day of finished motor gasoline and 34,543 bbl/day of low-density diesel fuel. The study provides an updated evaluation of cost, technical, and environmental performance. With an estimated total as-spent capital cost of 4.3 billion dollars (3.7 – 5.6 billion dollars) or $86,188 ($73,260 - $112,045) per bbl of daily production of Fischer-Tropsch liquids, such a facility would be commercially viable should the market conditions (liquid fuel and natural gas prices) remain as favorable or better throughout the life of the project than during the middle of May 2013. The life cycle GHG emissions for GTL diesel and gasoline when based on current practices in the natural gas industry are 90.6 g CO2e/MJ and 89.4 g CO2e/MJ, respectively. If the natural gas extraction and processing sector complies with NSPS, the upstream GHG emissions from natural gas are reduced by 23 percent. The key challenges of GTL are the risk associated with varying gas and product prices, the lack of sustained effort in its development, and its high capital costs. A robust research and development program, besides driving capital cost reductions, can serve the role of sustaining the deep knowledge base in GTL.


Assessment of the Distributed Generation Market Potential for Solid Oxide Fuel Cells

Date: 09/2013

            Contact: Katrina Krulla

NETL analyzed the strengths of the solid oxide fuel cell (SOFC) system in conjunction with distributed generation (DG) market segments in the U.S. and determined that natural gas compressor stations, grid strengthening, and data centers were potential early market-entry opportunities. These three DG market segments are projected to demand two gigawatts of additional power between now and 2018 and 25 GWs through 2040. This analysis showed that the DG SOFC system becomes cost competitive with other fossil-fuel based DG technologies after 25 MWe of installed capacity, around 2025. The SOFC DG application validates and enables utility scale fuel cell systems with carbon capture, and forms an essential first phase of the NETL technology development roadmap.

Potential Impact of Improved Sensors, Controls on Coal-Fired Power Plant Forced Outages

Date: 03/2013

            Contact: Katrina Krulla

NETL is funding advanced sensors and control technologies research that has the potential to decrease the number of forced outage hours experienced by Coal-Fired Power Plants. Historically, a coal-fired unit is forced to shut down between 200 and 600 hours per year due to unexpected component failures or human errors. These forced outages represent a significant loss of revenue to the utility with an average sized unit losing $15-$20 Million per year. This paper examines the potential economic impact of improvements in unit availability due to advances in sensors and controls technology.


Advanced Sensors and Controls - Techno-Economic Analysis for Existing Coal Generating Units

Date: 03/2013

            Contact: Katrina Krulla

NETL collected data from previous coal-fired power plant sensor and control projects and used this data to establish cost and performance ranges to determine the economic opportunity for future advanced senor and control retrofits. Unit-level economic analyses were performed on coal-fired power plants in the U.S. by calculating the net present value (NPV) of cash flows that occur after the installation of new advanced sensor and control technologies in 2020. The results indicate that all 863 coal-fired units in the U.S. would meet a 24-month payback criterion assuming that availability and heat rate would improve consistent with prior senor and control projects.

Evaluating the Impact of R&D and Learning-by-Doing on Fossil Energy Technology Cost Reductions: There Can be No Learning if There is No Doing

Date: 02/2013

            Contact: Katrina Krulla

Historical data has shown that as new technologies penetrate the market, costs are often reduced with each doubling in capacity because employees learn-by-doing. Learning curves are used by many models to forecast future capital costs for energy technologies including carbon capture. Caution should be taken when using learning curves to predict future capital costs because of the wide variation in learning rates and inability to separate the impacts of R&D. It is important to note that while learning-by-doing can bring costs down once a technology deploys, R&D is still necessary for the technology to become cost competitive.

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

Date: 11/2011

            Contact: Timothy Skone

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. The model determines the life cycle GHG emissions of biomass feedstocks from planting the biomass to delivery to the bioenergy plant gate ("farm-to-hopper”). Included are emissions associated with feedstock production, transportation, and processing (corn grain, corn stover, switchgrass [SG], mixed prairie biomass [MPB], 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 Updates to the model include several additions and corrections to CUBE 1.0. In particular, the functionality and scope have been expanded by adding two additional feedstocks (corn stover and hybrid poplar) and by increasing the number and complexity of processing and transport choices. Major modifications are summarized in corresponding Model Documentation.

Near-Term Opportunities for Integrating Biomass into the U.S. Electricity Supply: Technical Considerations

Date: 08/2011

            Contact: Timothy Skone

In light of potential regulatory limits on greenhouse-gas (GHG) emissions, requirements for greater use of renewable fuels, and higher prices for some conventional fossil resources, over the course of the next few decades, biomass is expected to become an increasingly important source of electricity, heat, and liquid fuel. One near-term option for using biomass to generate electricity is to cofire biomass in coal-fired electricity plants. Doing so allows such plants to reduce GHG emissions and, in appropriate regulatory environments, to generate renewable-energy credits to recover costs. This report focuses on two aspects of biomass use: plant-site modifications, changes in operations, and costs associated with cofiring biomass; and the logistical issues associated with delivering biomass to the plant. The authors find that the main challenge is maintaining a consistent fuel supply; technical and regulatory factors can drive the decision to cofire; cofiring can increase costs, decrease revenue, and reduce GHG emissions; densification does not reduce plant costs but can reduce transportation costs, however current markets cannot support use of densified fuels. This study was sponsored by the National Energy Technology Laboratory. The report is available on the RAND web-site at www.rand.org/pubs/technical_reports/TR984.html.

Supplying Biomass to Power Plants: A Model of the Costs of Utilizing Agricultural Biomass in Cofired Power Plants

Date: 08/2011

            Contact: Timothy Skone

U.S. power plants seek to diversify their fuel sources. Biomass energy is a renewable resource, generally with lower emissions than fossil fuels, and has a large, diverse base. To make decisions about investing in a facility that utilizes biomass, prospective users need information about infrastructure, logistics, costs, and constraints for the full biomass life cycle. The model developed in this work is designed to estimate the cost and availability of biomass energy resources from U.S. agricultural lands from the perspective of an individual power plant. As an illustrative example, the model estimates the availability and cost of using switchgrass or corn stover to power a cofired power plant in Illinois and estimates the plant-gate cost of producing biomass fuel, the relative proportions of switchgrass and corn stover, the mix of different land types, and the total area contributing the supplied energy. It shows that small variations in crop yields can lead to substantial changes in the amount, type, and spatial distribution of land that would produce the lowest-cost biomass for an energy facility. Land and crop choices would be very sensitive to policies governing greenhouse-gas emissions and carbon pricing, and the model demonstrates important implications for total land area requirements for supplying biomass fuel. This study was sponsored by the National Energy Technology Laboratory. The report is available on the RAND web-site at www.rand.org/pubs/technical_reports/TR876.html.

            Contact: Maria A. Hanley

Uniquely correlating the increased number of larger and longer-lasting frequency excursions in North American Interconnections with electricity market design and frequency control regulations, the report connects direct (technical) and indirect (non-technical) causes, both the physics of the problem and the regulatory environment (i.e., regulations, standards, and policies). The physical laws governing the frequency stability phenomenon and system control efforts are responsible for maintaining the nominal system frequency. However, the regulatory environment impacts policy on market design, affecting frequency stability and policies directly affecting frequency control practices. The report covers both technical and policy aspects to improve frequency stability.


Technical and Economic Analysis of Various Power Generation Resources Coupled with CAES Systems

Date: 06/2011

            Contact: Ryan Egidi

Compressed air energy storage (CAES) is an energy storage application with the potential to supplement intermittent power sources, such as wind and solar generators, and to enable better load following for more constant power sources such as coal combustion generators. To better understand CAES’s potential to provide practical energy storage for intermittent and constant-output power sources in the U.S., three practical considerations important to CAES planning and operations were analyzed: 1. Siting decisions 2. Development of optimal charge-discharge strategies 3. Design and operating factors that affect efficiency. These three analyses form the major sections of this study.

Current and Future IGCC Technologies: A Pathway Study Focused on Non-Carbon Capture Advanced Power Systems R and D Using Bituminous Coal - Volume 1

Date: 10/2008

            Contact: John G. Wimer

The impact of a portfolio of advanced technologies in DOE's Clean Coal R&D Program were evaluated in gasification-based power plant configurations (without carbon capture and sequestration) resulting in power plants that are significantly more efficient and affordable than today's limited set of fossil energy technologies. In the IGCC process alone, the study estimates that an 11 percentage point efficiency improvement over conventional gasification technology is possible. With fuel cell technology, process efficiency improvements upwards of 24 percentage points are potentially achievable. Capital cost reductions result not only from less expensive technology alternatives such as warm gas cleanup and ITM air separation, but also from increased power generation brought about by advanced technology such as syngas turbines, resulting in cumulative total plant cost reductions by as much as $700/kW. Improvements in process efficiency, reductions in capital and operating expense, and increase in capacity factor all contribute to decreased cost of electricity (COE), projecting an overall decrease by more than 3 cents/kW-hr, or a decrease of 35 percent.

Potential Application of Coal-Derived Fuel Gases for the Glass Industry: A Scoping Analysis

Date: 12/2004

            Contact: John G. Wimer

The objective of this study is to explore the economic viability of producing coal-derived fuel gases for use in the glass manufacturing industry as an alternative to natural gas. In this study small-size gasification systems that suffer adversely from economics of scale were not considered. Instead, full-scale commercial gasification systems were analyzed that could produce enough fuel gas and electric power for several manufacturing plants. The possibility exists to gather a number of large manufacturers in a geographically centralized location in an Industrial Gasification Island (IGI) complex so that a central coal gasification plant could economically provide fuel and power to all of these industries.
