CO2-EOR Offshore Resource Assessment

Date: 06/2014

            Contact: Evelyn Dale

The Gulf of Mexico accounts for about 20 percent of total domestic crude oil production.  Since reaching a peak of 1.54 million barrels a day in 2003, Gulf of Mexico’s OCS oil production has declined to 1.23 MMB/D, as of mid-2013.  While there is optimism that new discoveries in the deep and ultra-deep waters of the GOM OCS will reverse this decline, another option seems to offer even more promise -- the application of CO2 enhanced oil recovery.


Near-Term Projections of CO2 Utilization for Enhanced Oil Recovery

Date: 04/2014

            Contact: Phil DiPietro

In 2013 a total of 113 CO2-EOR projects inject 3.1 billion cubic feet per day (Bcfd) (60 million metric tons (MMmt) per year) of CO2 for enhanced oil recovery in the United States.  The associated crude oil production in 2012 was 282,000 barrels per day.  Based on the increased volumes of CO2 supplies, the completion of major CO2 pipelines, and the announced new, large-scale CO2-EOR floods, production of crude oil from CO2-EOR floods is forecast to grow significantly, reaching 615,000 barrels per day from at least 124 active CO2 floods by year 2020.  While the Permian Basin remains the largest CO2-EOR oil producer, much of the growth occurs in the Gulf Coast, the Rockies, and the Mid-Continent.

Subsurface Sources of CO2 in the Contiguous United States. Volume 1: Discovered Reservoirs

Date: 03/2014

            Contact: Phil DiPietro

Twenty-one CO2 fields in the contiguous states contain an estimated 311 Tcf of CO2 gas-initially-in-place (GIIP).  Of that, 168 Tcf (54 percent) is estimated to be accessible and technically recoverable.  The estimated economically recoverable resource (ERR) is 96.4 Tcf, based on a CO2 price of 1.06 $/mcf ($20/tonne) at the field gate.  Cumulative production to date is 18.9 Tcf, leaving 77.5 Tcf remaining or net ERR.  The Big Piney-LaBarge field in Wyoming contains an estimated net ERR of 52 Tcf, 67 percent of the total for the United States.  The remaining ERR in reservoirs that feed into the Permian Basin and Gulf Coast is on the order of 10-20 years of supply.


Subsurface Sources of CO2 in the United States. Volume II: Exploration of CO2 Systems

Date: 03/2014

            Contact: Phil DiPietro

A study of the genesis and tectonic setting of subsurface CO2 systems in the United States indicates that undiscovered CO2 reservoirs could contribute materially to CO2 supply for enhanced oil recovery.  Five geographic areas are estimated to contain 42 Tcf of risked technically recoverable CO2 resource (TRR).   Two lead areas near the Permian Basin, Val Verde and San Juan, contain 34 Tcf CO2 risked TRR, an amount roughly equivalent to the remaining TRR in discovered reservoirs that are currently supplying the region.  The number of lead areas studied was limited and the aggregate TRR estimates are not comprehensive.

LCA and the U.S. Natural Gas Resource

Date: 12/2013

            Contact: Timothy J. Skone

From a life cycle perspective, baseload power is NETL's preferred basis for comparing energy sources. For fossil energy systems, the emissions from power plants account for the majority of greenhouse gas (GHG) emissions. However, focusing on the activities that precede the power plant is still necessary in order to identify near-term opportunities for GHG emission reductions. NETL's upstream natural gas model allows detailed modeling of the extraction, processing, and pipeline transmission of natural gas. This model can identify key contributors to the GHG emissions from the natural gas supply chain, and has parameters that can be used to assess opportunities for reducing GHG emissions. The model shows that current domestic natural gas extraction, processing, and pipeline technologies leak 1.2% of the methane that is extracted at the wellhead. Improved practices, such as those in the latest New Source Performance Standards (NSPS), can reduce this upstream methane leakage rate. From a life cycle perspective (1 MWh of delivered electricity), power production from natural gas has lower GHG emissions than power produced from coal. There are several methods and technology combinations that can be used for determining how high the upstream natural gas methane leakage rate has to be in order for the life cycle GHG emissions from natural gas power to equal those from coal power. Ongoing research is developing data that will improve the accuracy of NETL's upstream natural gas model.

Using Life Cycle Analysis to Inform Energy Policy

Date: 12/2013

            Contact: Timothy J. Skone

NETL uses LCA to understand the environmental burdens of energy systems and to inform policy makers. LCA is well suited for energy analysis, but its answers can change depending on what questions are being asked. NETL approaches all LCAs using a consistent method, which ensures comparability among LCAs. The granularity and flexibility of NETL's models makes it possible to identify key contributors to the environmental burdens of a system, as well as the ability to understand how results can change with changes to a given input parameter. In addition to understanding the attributes of a given energy technology, NETL can also perform consequential modeling that allows an understanding of how a given energy technology can affect the performance of other energy technologies. The effect of enhanced oil recovery (EOR) on conventional crude oil extraction is one example of such consequential analysis. The results of consequential analyses have more uncertainty than those for analyses that focus on the attributes of isolated systems, but the conclusions of consequential analyses provide more context for policy makers.


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.


An In-Depth Look at "Next Generation" CO2 EOR Technology

Date: 09/2013

            Contact: Phil DiPietro

This analysis takes a more in-depth look at the "Next Generation" CO2-EOR concept and defines distinct areas of technology development that comprise it. The CO2-PROPHET model is used to simulate the application of the four main "Next Generation" technologies to a database of 1,824 Lower-48 onshore oil reservoirs, first applied singularly and then in combination. The simulations indicate significant synergy when the technology areas are applied jointly. The results show that "Next Generation" CO2 EOR can provide positive impacts – 2 MMbpd of domestic oil production for 50 years - but it is not free. "Next Generation" CO2-EOR designs require capital outlays two times higher than current best practices.


CO2 STORAGE AND UTILIZATION NEAR MINGO COUNTY, WEST VIRGINIA

Date: 09/2013

            Contact: DiPietro, Phil

Six oil fields within 100 miles of the planned coal-to-liquids facility in Mingo County were found to be prospective for miscible CO2-EOR. Four of the oil fields fall along a straight line and could, in concept, be developed sequentially along a single CO2 pipeline. The total demand for purchased CO2 from these four fields is estimated to be 47 million metric tons (890 Bcf) over 20 years. Four saline formations within Mingo County could accommodate 50 million metric tons of CO2 (accounts for uncertainty and a &"buffer zone”). The combined storage capacity – EOR within 100 miles of Mingo County and saline within Mingo County – can accommodate 3 million metric tons per year of vented CO2 for over 30 years Conclusion: there is enough potential for CO2 utilization and storage that a next level of study is a reasonable course.

Conventional Generation Asset Management with Renewable Portfolio Standards Using Real Options

Date: 05/2013

            Contact: Peter Balash

The transition to a more renewable generation mix under a competitive electricity market will require individual power producers to use sophisticated tools to value conventional generators. Owners will need to understand what market prices signal new investments, temporarily suspending operation, reactivating mothballed generators or permanently abandoning a plant. Net present valuation from a traditional discounted cash flow analysis is limited in capturing the value of generation technologies, and it does not provide an optimal investment criterion. We present and evaluate a closed-form decision support framework using a Spark Spread Real Options approach to value generation assets and to capture optimal market price signals that minimizes financial risks of individual power producers under a transition towards a more renewable energy fleet.

A Forecast of Crude Oil Production from Carbon Dioxide Enhanced Oil Recovery in the United States through 2018

Date: 03/2013

            Contact: Phil DiPietro

CO2 supply for enhanced oil recovery operations in the United States is expected to increase 64% between 2012 and 2018, from 3.3 BCFd to 5.4 BCFd. The CO2 utilization rate (URNet the amount of CO2 supplied per incremental barrel of crude oil produced) can be used to estimate crude oil production based on CO2 supply rate. Based on compiled historical data we estimate the following regional CO2 Utilization rates: Permian basin, 8,500 scf/bbl, Rocky mountain, 8,000 scf/bbl, Gulf Coast, 25,000 scf/bbl. Applying these rates to the regional forecast for CO2 supply we forecast production from CO2 EOR in the United States in 2018 will be 500,000 bpd.


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.

This model includes costs from initial regional geologic evaluation through site characterization, permitting, injection/MVA operations, post-injection site care to final site closure and transfer to long-term stewardship. A geologic and cost database was developed to support this model.

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.

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.


Improving Domestic Energy Security and Lowering CO2 Emissions with “Next Generation” CO2-Enhanced Oil Recovery (CO2-EOR)

Date: 06/2011

            Contact: Phil DiPietro

NETL has revised its national resource assessment for carbon dioxide enhanced oil recovery (CO2 EOR). Under a current technology scenario, 1,200 reservoirs in the lower 48 states are amenable to CO2 EOR. At an assumed crude oil market price of $85 per barrel, these reservoirs represent 24 billion barrels of economic reserves. Under a next generation scenario the economic supply from CO2 EOR increases to 60 billion barrels. The resource assessment unveils a strong dependence on CO2 capture technology, as the equivalent of 60 - 90 GW of coal-fired plants with 90% capture will be needed to supply EOR floods.

Analysis of Natural Gas Fuel Cell Plant Configurations

Date: 05/2011

            Contact: Walter Shelton

This report presents the results of a Pathway Study for natural gas fueled, fuel cell (NGFC) power systems with carbon capture and sequestration (CCS). The results quantify the performance and cost benefits for a series of projected gains made through the development of advances in the component technologies or improvements in plant operation and maintenance. The design and cost bases for this pathway study closely follows the bases applied in the NETL, 2010, Bituminous Baseline report so that direct performance and cost comparisons can be made with the conventional fossil-fuel power plant results estimated in that report. Performance and cost projections for a baseline integrated gasification combined cycle (IGCC) power plant, a baseline natural gas combined cycle (NGCC) power plant, and prior coal-based integrated gasification fuel cell (IGFC) pathways, are compared with the results for the NGFC pathways. The results represent the potential future benefits of NGFC technology development. They also provide DOE with a basis to select the most appropriate development path for NGFC, and to measure and prioritize the contribution of its R&D program to future power systems technology.


Life Cycle Greenhouse Gas Analysis of Natural Gas Extraction & Delivery in the United States

Date: 05/2011

            Contact: Timothy Skone

On May 12, 2011 NETL provided the following presentation at the Cornell University lecture series on unconventional natural gas development. The presentation summarizes the life cycle analysis (LCA) greenhouse gas (GHG) research on natural gas extraction and delivery in the United States (on a lb CO2e/MMBtu basis) and a comparison of the life cycle GHG profiles of average natural gas and coal-fired power production and delivery to an end-user (lb CO2e/MWh basis). Specifically, the presentation details seven natural gas profiles: onshore conventional gas, associated gas, offshore gas, tight sands (gas), shale gas (based on Barnett Shale), coal bed methane gas, and the year 2009 domestic average mix. Each natural gas source is upgraded in a gas processing plant, compressed, and delivered to a large end-user (e.g., power plant).


Thermal Plant Emissions Due to Intermittent Renewable Power Integration

Date: 05/2011

            Contact: Maria A. Hanley

Answering the question of whether operating one or more natural-gas turbines to firm variable wind or solar power would result in increased Nitrous oxide (NOx) and Carbon Dioxide (CO2) emissions compared to full-power steady-state operation of natural-gas turbines, the analysis demonstrates that CO2 emissions reductions are likely to be 75-80% of those presently assumed by policy makers. NOx reduction depends strongly on the type of NOx control and how it is dispatched. For the best system examined, using 20% renewable penetration, the NOx reductions are 30-50% of those expected; in the worst, emissions increased by 2-4 times the expected reductions.

            Contact: Walter Shelton

This report presents the results of a Pathway Study for coal-based, integrated gasification fuel cell (IGFC) power systems with carbon capture and sequestration (CCS). The results quantify the performance and cost benefits for a series of projected gains made through the development of advanced technologies or improvements in plant operation and maintenance. The results represent the potential future benefits of IGFC technology development. They also provide DOE with a basis to select the most appropriate development path for IGFC, and to measure and prioritize the contribution of its R&D program to future power systems technology. The IGFC plants in this study apply advanced, planar, solid oxide fuel cell (SOFC) technology with separate anode and cathode off-gas steams, and incorporate anode off-gas oxy-combustion for nearly complete carbon capture. The SOFC simulations utilize the expected operating conditions and performance capabilities of this solid oxide fuel cell technology, operating initially at atmospheric-pressure. The power plant cost and performance estimates reflect performance projections based on the current state of SOFC development, as well as projecting a pathway of SOFC technology development advances.

Carbon Capture Approaches for Natural Gas Combined Cycle Systems

Date: 01/2011

            Contact: Walter Shelton

This study develops ASPEN PLUS simulation models and cost estimates for Natural Gas Combined Cycle plants with CO2 capture. Three approaches for carbon capture are examined: pre-combustion, post-combustion and oxy-combustion. In pre-combustion carbon capture, the carbon in the fuel is converted to CO2 and removed before the combustion process, whereas in post-combustion, the more dilute CO2 is separated from the flue gas at a lower pressure. Oxy-combustion technologies use nearly pure oxygen as the oxidant so that the flue gas consists primarily of CO2 and water vapor. Case results are compared with a reference plant based on an 7F frame combustion turbine.

Framework and Guidance for Estimating Greenhouse Gas Footprints of Aviation Fuels

Date: 04/2009

            Contact: Phil DiPietro

This report provides framework and guidance for estimating the life cycle greenhouse gas emissions for transportation fuels, specifically aviation fuels. The focus on aviation fuels was driven by the patterns of fuel use by the federal government. Policies such as those outlined in Section 526 of EISA 2007 cause federal agencies to institute enforceable guidelines for procuring low carbon alternative fuels. Federal consumption of fuels is dominated by the Department of Defense and the Air Force consumes more fuel than any of the other military services or federal agencies (Defense Science Board 2008). Thus, aviation applications may become early adopters of low carbon transportation fuels. The U.S. Air Force convened a working group of individuals from government agencies, universities and companies actively engaged in assessing greenhouse gas emissions from transportation fuels, and requested that this group develop guidance on procedures for estimating greenhouse gas emissions in aviation applications, using currently available data and tools.

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.

Impact of Sulfur Oxides on Mercury

Date: 09/2007

            Contact:

In order to gain a more complete understanding of the impact of SOx on ACI, mercury capture was tested under varying conditions of SO2 and SO3 concentrations using a packed bed reactor and simulated flue gas (SFG). The final mercury content of the activated carbons is independent of the SO2 concentration in the SFG, but the presence of SO3 inhibits mercury capture even at the lowest concentration tested (20 ppm). The mercury removal capacity decreases as the sulfur content of the used activated carbons increases from 1 to 10%. The results suggest that mercury and sulfur oxides are in competition for the same binding sites on the carbon surface.
