Development of Cost-Competitive Advanced Thermoelectric Generators for Direct Conversion of Vehicle Waste Heat into Useful Electrical Power

General Motors LLC (GM) proposed a project to develop a cost-effective thermoelectric generator (TEG) that is fully integrated into a GM production light-duty vehicle. The project goal was to reduce automotive energy consumption and CO 2 emissions by generating usable electricity from exhaust gas waste heat. The project objectives were to overcome the major obstacles to TEG commercialization and demonstrate 5% fuel economy improvement over the US06 drive cycle. We investigated electrical and thermal management strategies that included: (1) reducing electrical accessory load on the alternator using thermoelectric (TE) generated power; (2) shifting engine-driven accessories to electrical drive to raise the electrical accessory load consumption; (3) attempting to use the excess electrical power for something other than the vehicle electrical load e.g., propulsion (optimal for hybrids); and (4) implementing fast engine/transmission warm-up during cold-start. We developed a TEG system and all vehicle controls and electrical systems for full vehicle integration. The TEG system was modeled and analyzed for performance and cost. Heat exchangers and thermal interfaces between heat exchangers and TE modules were optimized for TE performance. Other objectives of the project were to (1) further optimize compositions and processing parameters for TE materials, (2) develop suitable diffusion barriers, interfaces electrical interconnections, and thermal contacts within TE modules, (3) implement adequate protection of TE materials and modules from degradation during operation, and (4) develop manufacturing and assembly processes for large scale production of TE materials and components that include scale-up plans for the production of 100,000 TEG units per year.

Safeguards in Pyroprocessing: an Integrated Model Development and Measurement Data Analysis

Pyroprocessing is an electrochemical method based on the molten salt electrolyte, mainly the LiCl-KCl eutectic molten salt, to recycle the used nuclear fuel. For a conceptual design of commercial pyroprocessing facility, tons of special nuclear materials, namely U and Pu, may be involved, which could be used for non-peaceful purposes if they are diverted. Effective safeguards approaches have to be developed prior to the development and construction of a pyroprocessing facility. Present research focused on two main objectives, namely calculating the properties of nuclear species in LiCl-KCl molten salt and developing integrated model to safeguard a pyroprocessing facility. Understanding the characteristics of special nuclear materials in LiCl-KCl eutectic salt is extremely important to understand their behaviors in an electrorefiner. The model development for the separation processes in the pyroprocessing, including electrorefining, actinide drawdown, and rare earth drawdown benefits the understanding of material transport and separation performance of these processes under various conditions. The output signals, such as potential, current, and species concentration contribute to the material balance closure and provide safeguards signatures to detect the scenarios of diversion. U and Pu are the two main elements concerned in this study due to our interest in safeguards.

Development of Geomechanical Screening Tools to Identify Risk: An Experimental and Modeling Approach for Secure CO 2 Storage Final Technical Report

CO 2 injection in the subsurface introduces additional complexity in terms of interactions of the reservoir host pore fluid with natural heterogeneity of hydro-mechanical properties of the rock. Natural heterogeneity of the reservoir rock and caprock formations includes spatial variation of hydro-mechanical properties as well as the presence of natural fractures. We developed a coupled mathematical modeling and experimental framework that takes into account the effect of rock heterogeneity on effective mechanical properties of the rock in contact with CO 2 . We performed accurate laboratory experiments to determine the changes in rock mechanical properties due to mineral dissolution in the presence of carbonic acid generated by CO 2 injection. A two-scale adaptive homogenization framework was then developed to consistently upscale petrophysical and geomechanical properties to the field scale. Further, we also developed high-fidelity, numerical solution schemes, non-linear and linear solvers and preconditioners to solve the coupled flow, reactive transport and geomechanical system. The numerical model was then used to study field scale CO 2 sequestration problems for the two selected field sites: (1) Frio formation and (2) Cranfield site. We also developed robust schemes for field data assimilation, model calibration such that the residual uncertainty at the end of the data assimilation procedures can be faithfully represented while taking into account the coupled geochemical and geomechanical processes.

Domain Specific Language Support for Exascale Application Development

The University of Oregon has produced a Fortran parser based on an SDF (Syntax Definition Formalism) grammar. Primary partners in this effort were Rice University and Lawrence Livermore National Laboratory. The developed Fortran parser incorporates the full Fortran 2008 standard with extensions from the more recent document, TS 29113, “Further Interoperability of Fortran with C,” (to be included in the Fortran 2018 standard). In the final year of the project, the Fortran parser was updated to comply with the complete 2018 standard, as specified in the ISO/IEC document, JTC 1/SC 22/WG 5/N2146. The research explored in this project provided the expression of the Fortran grammar in SDF form for integration with the Rosebud DSL framework developed by Rice University. The Rosebud framework is a cohesive interface allowing modular DSL plugins to be developed independently and then distributed and combined in HPC applications. These plugins implement a form of generalized DSL which includes both concrete languages used to write application source code and abstract languages used within the compilation process. ROSE’s predefined DSL Building Blocks (for example the Fortran base language) are represented as abstract language plugins and DSL developers can use Rosebud to construct additional building blocks in the same way.

Big Area Additive Manufacturing (BAAM) Materials Development and Reinforcement with Advanced Composites

Additive manufacturing (AM) by extrusion deposition is rapidly developing as an energy efficient process that greatly reduces development time for new products including vehicle structures. Development of reinforced thermoplastic compounds that are specifically tailored to the AM process and possess the properties necessary for engineering structures is currently underway. This project focused on developing a fundamental understanding of printability by performing a number of polymer characterization tests, initial printability screenings, and basic mechanical property determinations for a number of compounds. Structural evaluations of more complex printed articles were also performed in order to build a database of mechanical performance for validation of structural simulations planned for Phase II. Included in the structural tests were components that were reinforced using a number of methods including over-wrapping with dry fabric and resin infusing to form an advanced composite having the shape of the 3D printed structure. The results indicate a number of factors that affect printability of materials, and initial structural analysis shows that the data generated will be useful for model validation.

South Carolina Solar Development - Tracking the Effects of Act 236 (2014-2017)

Since 2014, the installed solar capacity in South Carolina (SC) has mushroomed from 5.5 megawatts to more than 354 megawatts today. Concurrently, the number of customer-sited, load-centered solar generation was expected to grow from less than 600 statewide to as many over 10,000 today. This growth was the direct result of a landmark state policy initiative, Act 236, passed by the SC General Assembly and signed into law by the Governor in June of 2014. Local policy makers in SC were ill-equipped to handle the onslaught of solar permitting and zoning requests expected by 2021. Similarly, the state’s building inspectors, first responders, and tax assessors know little about photovoltaic (PV) technology and best practices. Finally, SC’s workforce and workforce trainers were underprepared to benefit from the tremendous opportunity created by the passage of Act 236. Each of these deficits in knowledge of and preparedness for solar PV translated into higher “soft costs” of installed solar PV in SC. The Savannah River National Laboratory (SRNL), together with almost a dozen electricity stakeholders in the Southeast, has studied the ability of Act 236 to serve as replicable model for solar PV cost reduction. In 2015, this study began with a focus on the effects of Act 236 to offer a unique perspective and understanding of the actual impact of rapidly integrating solar energy into the electric grid. This study would analyze the impact of starting at a solar PV penetration of 0.1% and increasing to over 2%, while expanding access, developing regional specific training and educational materials, and developing datasets to support expanding solar markets. Through targeted tracking and analysis, the team developed a baseline of the current market, identified the major obstacles in soft cost reduction, and cooperatively developed stakeholder-centric strategies. This work has enabled us to directly track and report on the growth and effects of recently enacted solar legislation on the industry. This report marks the final in a series of reports examining the effects of Act 236 on the solar economy in SC since 2014.

RFA for Solar/Geothermal Hybrid Thermal Energy Storage Modeling: Cooperative Research and Development Final Report, CRADA Number CRD-16-646

Hyperlight Energy is an innovative concentrated solar power (CSP) company whose business charter is to commercialize a disruptively low-cost, CSP collector system that is ultimately for providing heat for solar thermal/geothermal hybrid power plants, process heat applications (e.g., enhanced oil recovery), and solar thermal power generation. Hyperlight's CSP collector system utilizes a linear Fresnel reflector (LFR) configuration. This LFR configuration consists of mirrors mounted in low-cost, precision plastic extrusions, which are integrated into raft assemblies and floated on low-cost, sealed waterbeds. Hyperlight's CSP collector technology has been developed under private equity investment, government grant and commercial funding. Hyperlight has been awarded a 1.5-million DOE COLLECTS contract with an additional 1.6 million in matched funds from private investment and the California Energy Commission. This DOE project will support the final steps of product development for bulk commercialization and deployment of the Hyperlight CSP collector system. The work will culminate in a final operational deployment at a commercially relevant site. Several such site options are currently under evaluation, including two geothermal sites. Hyperlight identified a very low-cost way to put renewable energy electrons on the grid at peak times, upgrading underutilized geothermal plants with Hyperlight's low cost CSP and thermal energy storage (TES). While Hyperlight's CSP collector work is maturing quickly for commercial pilot launch, an optimal TES system for solar thermal/geothermal hybridization needs to be evaluated and ultimately developed so Hyperlight can develop commercial retrofit projects at a scale of hundreds of megawatts of renewable energy power output at sites across the United States, followed by greenfield projects in a multi-GW sized market.

NREL and Be Power Tech, Inc. (Be Power) will jointly develop a new combined cooling, heating, and power (CCHP) system that uses desiccants in combination with evaporative cooling and fuel cells. The combined system will have better economics and business case than a separate desiccant enhanced air conditioner and fuel cell system. The overall system is expected to become a net revenue generator by delivering power and air conditioning to a building while inputting natural gas and water. This development effort will revolve around adapting NREL's desiccant cooling technology to work with Be Power's proprietary system integration design for CCHP systems. The objective of the CRADA is to develop, then commercialize this CCHP system by jointly developing the system integration design, testing methods, and hardware for this system. The commercial name given to the CCHP system is BeCool.

Development of Preliminary VERA-CS Crud Induced Localized Corrosion Modeling Capability

The objective of this milestone was to develop a crud-induced localized corrosion (CILC) screening capability in VERA-CS using existing codes and capabilities that had been developed in the Consortium for Advanced Simulation of Light Water Reactors (CASL) as part of the efforts to resolve the crud challenge problem. The milestone work focused on improving existing CASL software and implementing clad corrosion modeling into VERA-CS. Clad corrosion modeling was implemented by creating an application interface (API) in the Cicada software so that its clad heat transfer and corrosion models could be used in VERA-CS. Cicada was coupled to the subchannel code CTF for solving crud and corrosion growth. Additionally, a clad corrosion model was added directly to CTF to serve as an alternate approach. The rod thermal hydraulic reconstruction (ROTHCON) process, which is used for capturing computational fluid dynamics (CFD)-predicted rod-surface heat and turbulence behavior that can impact crud-induced power shift (CIPS) and CILC prediction, was also implemented into VERA-CS. Usability improvements were made to this feature, which was developed over several previous milestones, so that the VERA-CS user can link spacer grids in a VERA-CS model to an applicable pregenerated spacer grid data file if available. Several assessments were performed to demonstrate the proper functioning of the new capability. Sensitivity studies were performed to demonstrate the effect of crud lithium content, oxide thermal conductivity, Cicada mesh refinement, and ROTHCON coupling mesh refinement on predicted amounts of crud and oxide growth. A full-scale demonstration was performed by running Seabrook Cycle 5 with the CILC capability. Some general observations were made from the assessments. It was observed that predicted corrosion thickness is less than anticipated for CILC cases, so further work is needed to better understand and improve the corrosion modeling. Refining the coupling mesh in the ROTHCON process leads to increased corrosion and crud thickness, which can affect where crud and corrosion grow, how thick it gets, and how many rods experience crud and corrosion growth. Results indicate that applying the ROTHCON process and refining the coupling mesh leads to only a slight increase in total core maximum crud and corrosion thickness, but it leads to a significant increase in the number of rods with a maximum thickness that surpasses a set threshold value (i.e., more rods grow thicker corrosion and crud). Computational performance of the simulation is degraded by a factor of 5{6 with high coupling mesh refinement. The impact of the ROTHCON coupling mesh refinement on total core crud mass is less significant; however, using the ROTHCON process with CFD-generated data over the Yao{Hochreiter{Leech (YHL) model in CTF leads to significantly different amounts of total core crud mass. Future work on the CILC screening capability will include model improvement and validation, development and testing of a CILC-risk screening criteria, and performance improvements.

Status Report on the Component Models Developed in the Modelica Framework: Reverse Osmosis Desalination Plant & Thermal Energy Storage

This report has been prepared as part of an effort to design and build a Modeling and Simulation (M&S) framework to assess the economic viability of a Nuclear-Renewable Hybrid Energy System (N-R HES). In order to facilitate dynamic M&S of such an integrated system, research groups in multiple national laboratories and universities have been developing various subsystems as dynamic physics-based components using the Modelica programming language. In Fiscal Years (FYs) 2015, Idaho National Laboratory (INL) performed a dynamic analysis of two region-specific N-R HES configurations, including the gas-to-liquid (natural gas to Fischer-Tropsch synthetic fuel) and brackish water Reverse Osmosis (RO) desalination plants as industrial processes. In FYs 2016–2017, INL developed two additional subsystems in the Modelica framework: (1) a high-temperature steam electrolysis plant as a high priority industrial plant to be integrated with a light water reactor within an N-R HES and (2) a gas turbine power plant as a secondary energy supply. In FY 2018, the RO desalination system model developed in FY 2015 has been updated such that the model is compatible with the most recent version of the ThermoPower library. Special attention has been given to the controller settings based on process models, aiming to improve process dynamics and controllability. A dynamic performance analysis of the updated RO desalination plant was carried out to evaluate the technical feasibility (load-following capability) of such a system operating under highly variable conditions requiring flexible output. Simulation results involving several case studies show that the suggested control scheme could maintain the controlled variables (including the variable electrical load and RO feed pressure) within desired limits under various plant operating conditions. The results also indicate that the proposed RO plant could provide operational flexibility to participate in energy management at the utility scale by dynamically optimizing the use of excess plant capacity within an N-R HES. For a small-scale energy storage system, a sensible Thermal Energy Storage (TES) model has been developed in the Modelica Framework in FY 2018.

Final Report - Sensor Development for Future e + e - Colliders

This project advances electromagnetic calorimeter sensor development for future electron-positron colliders, particularly the International Linear Collider (ILC). The ILC, under consideration for construction in Japan, will collide electrons and positrons at a 500 GeV baseline center-of-mass collision energy. The multi-volume ILC Technical Design Report describes two detector concepts, SiD and ILD, based on their “Detailed Baseline Design” documents. SiD and ILD are continuing to develop their technologies in anticipation of a positive decision from Japan in 2018. The ILC and its detectors will make unprecedented precision measurements relating to the Higgs boson and the top quark, and search for new phenomena that could be missed at the LHC, such as electroweak particles expected in some beyond the standard models. The sensor development covered by this project primarily pertains to the electromagnetic calorimeters (EMCal). This work continues conceptual work towards realistic modules. It is important to emphasize that the HEP sensor development on this project will enable applications beyond HEP. It does not include detector engineering. This proposal is a collaboration among one National Laboratory and four universities from Japan and two National Laboratories and four universities from the U.S.

Hydropower Development Opportunities for Alaska Native Villages

This report consolidates efforts among Oak Ridge National Laboratory (ORNL), the United States Department of Energy's (DOE) Office of Indian Energy Policy and Programs, and the Alaska Energy Authority (AEA) to evaluate opportunities for hydropower development among 171 Alaska Native villages. This research builds upon new stream -reach development (NSD) research [3] conducted by DOE/ORNL and geospatial modelling provided by the Bureau of Indian Affairs (BIA) [ 2 ]. Based on that information, ORNL has developed a model that evaluates village diesel (gallons) consumption, cost, price per gallon, and kilowatt-hours produced and purchased [4], in conjunction with the past analyses of DOE and BIA, to identify potential benefits of diesel offset from hydropower development on a yearly and 50-year (assumed hydro project lifespan) basis.

Development and Characterization of High Performance and Robust Mixed Conducting Cathodes Supportive of Lower Cost Solid Oxide Fuel Cells (Final Report)

The objective of the proposed research is to advance an existing partnership between the University of South Carolina (USC) and LG Fuel Cell Systems, Inc. (LGFCS) to research and develop mixed electronic and ionic conducting cathode materials for durable and robust low-cost solid oxide fuel cells (SOFCs). The first task is to develop mixed ionic and electronic conducting doped (Pr,Nd)NiO 4 (PNNO)-based cathodes. This task is built on a prior collaborative work with LG Fuel Cell System, which showed that doped PNNO could exhibit phase stability at high temperatures. The initial focus will be on investigating the durability and endurance of its electrochemical performance and the temporal evolution of microstructures. In-situ high temperature neutron diffraction and x-ray diffraction will be used to study the structures of these phase stable compounds. PNNO doped with Ca and transition metal elements will be synthesized. Physical properties of these materials with respect to coefficient of thermal expansion, electrical conductivity, diffusion coefficient, and nonstoichiometry will be measured. The benefits of dense versus porous barriers will be studied and the role of barrier layer will be identified and a guideline will be provided to choose the maximum porosity for durable and robust cathode performance with co-doped PNNO as the cathodes. LSCF6428 will be used to compare its power density with that of co-doped PNNO in the absence of Cr, but some studies comparing Cr tolerance will be performed towards the end of the project. The conditions at which preferred nickelate phases are stable will be defined, including sintering temperature, operating temperature, and composition range. The second task will focus on the investigation of the location of degradation by using differential relaxation time (DRT) analysis, coupled with least squares fitting and systematical post analyses. DRT analysis can provide (1) a direct access to the kinetic parameters of the underlying processes in both cathode and anode, and (2) a clearer picture of SOFC operation, which allows loss factors to the changes of microstructures or activities of either electrode to be distinguished, and a better target fuel cell development to be enabled. The third task aims at applying the accelerated testing protocol to investigate the microstructural evolution of the cathode candidates identified in this research. Technical approaches will be developed to mitigate and improve the durability of cathode materials by choosing the right chemistry and tuning cathode microstructures.

UW Translational Imaging Biomarker and Therapeutic Development

The development and validation of radiotracers is a critical step in the clinical translation of molecular imaging and theranostics to support personalized medicine. The proposed program is to support such efforts by an interdisciplinary team of investigators at the University of Washington (UW) and Fred Hutchinson Cancer Research Center (FHCRC) and to provide opportunities for trainees to learn the spectrum of translational research in imaging biomarkers and therapeutic development. The proposed translational research projects include "Preclinical Evaluation of PET Imaging for Use in the Translation of Targeted Alpha Therapy of Blood-Related Cancers to Clinical Studies" (Project 1-Wilbur, leader); "Hypoxia Imaging: Radiopharmaceuticals, Preclinical Studies, Mechanisms and Clinical trials" (Project 2-Krohn, leader); and "Diagnostic Applications of Radiolabeled Biologics in Solid Tumors" (Project 3-Minoshima, leader). These projects use radiotracers with long half-lives, such as F-18, Zr-89, I-124, and At-211, that can potentially be handled commercially if translation research is successful. The proposed research method is to use an interdisciplinary 'team' of expert investigators and trainees working on a specific project for 1 or 2 years along the timeline and milestones set by the Program Directors. Each team includes 1) a clinician expert; 2) a radiochemistry expert; 3) an imaging or radiation therapy expert; 4) a physicist; 5) trainees; and 6) a UW technology transfer officer. Two groups of trainees will be involved: clinical and basic science (radiochemistry) trainees. Clinical trainees will be recruited from 3 training programs: Nuclear Medicine Resident Program; Radiology Residency Program; and Residency Program in Radiation Oncology. Basic science trainees will be graduate students from degree-awarding departments (chemistry, material sciences, bioengineering) or post-doctoral students (radiology, radiation oncology, or collaborating departments). A goal of training is to develop future investigators who will be able to conduct independent translational research with knowledge and expertise earned in this interdisciplinary team environment. To address clinically relevant questions, the program will organize regular brainstorming meetings participated by clinicians from various medical disciplines; program investigators; trainees; technology transfer officers to discuss medical questions, relevant targets, and technical feasibility. UW provides outstanding research and clinical facilities and resources that can be accessed by investigators. The Departments of Radiology and Radiation Oncology at UW have been at the forefront of translational imaging and therapeutics research efforts in cancer, neurological disorders, and cardiovascular diseases. This funding opportunity will solidify ongoing efforts of interdisciplinary collaborations at UW into a cohesive program that will train a new generation of investigators. This will, in turn, accelerate the translational potential of new radiotracers by rapid developments of proof-of-concept and first-in-man studies along with in vivo validations in a clinically relevant context.

Developing a Human Factors Engineering Program Plan and End State Vision to Support Full Nuclear Power Plant Modernization

The Light Water Reactor Sustainability (LWRS) Program, which is sponsored by the United States (U.S.) Department of Energy (DOE), conducts research and development (R&D) to establish the technical bases to sustain U.S. nuclear assets. One area in the LWRS program is the Plant Modernization pathway, which includes human factors R&D, human factors engineering (HFE), and ergonomics. LWRS program researchers in this pathway conduct targeted R&D to address aging and reliability concerns with the legacy instrumentation and control (I&C) and related information systems in commercial nuclear power plants (NPPs). One key aspect of this pathway is to develop a strategy for full nuclear plant modernization, which previous LWRS plant modernization milestone reports have begun to describe. To further support this comprehensive plan and vision for full plant modernization, additional details need to be further developed. In particular, a core aspect of a strategy for full nuclear plant modernization is an HFE program plan and an end state vision for plant modernization that is well-integrated with both 1) a technically defensible approach to migrating the existing, mostly analog I&C infrastructure to a digital I&C infrastructure, and 2) a valid business case methodology to cost-justify the modernization activity. Thus, the purpose of this LWRS R&D activity and milestone report is threefold. First, the report provides guidance for operating commercial NPPs to support their development and evaluation of an HFE program management plan (HFE PMP) and an end state vision for plant modernization. The report presents best practices and lessons learned related to HFE PMPs based on MCR modifications in which analog systems were replaced by digital I&C systems. Second, the report summarizes the rationale for full digital I&C integration, highlights a number of factors that are critical to consider, and describes how HFE should merge with full digital I&C integration. Finally, the report summarizes and integrates the economic factors that must be considered to cost-justify HFE involvement in plant modernization.
