Cooperative self-assembly for structure and morphology control of energetic materials

The performance of energetic materials (EM) varies significantly across production lots due to the inability of current production methods to yield consistent morphology and size. Lot-to-lot variations and the inability to remake the needed characteristics that meet specification is costly, increases uncertainty, and creates additional risk in programs using these materials. There is thus a pressing need to more reliably formulate EMs with greater control of morphology. The goal of this project is to use the surfactant-assisted self-assembly to generate EM particles with welldefined size and external morphologies using triaminotrinitrobenzene (TATB) and hexanitrohexaazaisowurtzitane (CL-20) as these EMs are both prevalent in the stockpile and present interesting/urgent reprocessing challenges. We intend to understand fundamental science on how molecular packing influences EM morphology. We develop scale up fabrication of EM particles with controlled morphology, promising to eliminate inconsistent performance by providing a trusted and reproducible method to improve EMs for NW applications.

Technical Assistance in Fabrication and Testing of MEAs: Cooperative Research and Development Final Report

Altergy's fuel cell cost is highly dependent on expensive purchased membrane electrode assemblies (MEAs), which amount to 42¢/watt in a 5kW system. In order to better compete with other power solutions, the company has identified an MEA breakthrough cost of 20¢/watt to unlock new, major markets for its fuel cell products. Since Altergy presently does not have an accurate cost model for the real costs of these MEAs, it is difficult to know whether the company goal is achievable. Altergy seeks to leverage NREL expertise to reduce cost and improve performance for Altergy's fuel cell products. The objective of this Small Business Voucher (SBV) project therefore will be for NREL and Altergy to work together in three major task areas: 1) demonstrating the fabrication of MEAs at NREL using NREL non-proprietary methods, to the intent of potentially fabricating MEAs at Altergy to reduce product costs; and, 2) creating a cost model to assist Altergy in manufacturing decisions.

Materials and Device Architectures for Organic Solar Cell Applications: Cooperative Research and Development Final Report, CRADA Number CRD-09-355

The Centre for Organic Photonics & Electronics (COPE) at UQ has been successful in acquiring funding from the Australian Center for Advanced Photovoltaics (ACAP), which is the Australian partner of the Australia-US Institute for Advanced Photovoltaics (AUSIAPV). NREL is a key partner in AUSIAPV (along with other US research institutions (ASU, Sandia NL, LBNL, Stanford, Georgia Tech and UCSB). NREL will collaborate with COPE to advance the science and technology of organic materials for solar cell applications. COPE has significant programs in the development and understanding of new materials for organic optoelectronic applications and, in particular, for thin film bulk heterojunction (BHJ) solar cells and Organic Photodiodes (OPDs). NREL has significant established research programs in all aspects of organic photovoltaic technology and has well-developed expertise in the area of materials characterization, photocarrier transport measurements as well as device fabrication, scale-up and stability. This collaboration will combine the expertise of the two institutions to work towards demonstrating the scalability of organic materials for BHJ and OPD applications by measuring the fundamental properties of the materials as a function of processing and evaluating their performance and stability in photovoltaic devices under simulated illumination conditions. Currently, both NREL and UQ have individual organic material development and processing efforts and have independently demonstrated several prototype materials and device architectures as promising candidates for organic solar cells and OPDs. This CRADA will align these efforts building upon strengths of the two institutions to further design and demonstrate materials and device architectures to advance organic BHJ solar cells and OPDs. It should also be clearly noted that we foreshadow possible expansion of collaborative research activities between COPE and NREL, which currently lie outside the scope of the current statement of work, which will be amended as required by mutually executed written modifications to this CRADA.

Cordova Electric Cooperative Energy Storage Evaluation

The community of Cordova, Alaska currently uses diesel and run-of-river hydro generation for its electricity needs. In the past, 60% of the Cordova summer load was supplied by the run-of-river generation. The majority of the time, the load was supplied only by the run-of-river generation. The bulk of generated electricity is delivered to Cordova's industrial fish processing plants and to other industrial loads. With the expansion of Cordova's fishing industry, the run-of-river generation is less often able to supply 100% of the load demand. When the run-of-river generation is not able to supply 100% of the load demand it has to be supplemented by diesel generation. There are also many times when the load demand is low and the available run-of-river generation has to be curtailed by spilling water which could be stored in an energy storage system. Sandia National Laboratories and Alaska Center for Energy and Power collaborated to evaluate how an energy storage system can be used to capture the spilled water and how it can economically and technically benefit Cordova during the fishing season and other times throughout the year. Results from this study are summarized in this report.

Cooperative Research and Development Agreement between Applied Minerals, Columbian Chemicals Company and National Energy Technology Laboratory

NETL researchers will be collaborating with Applied Minerals, Inc., and Columbian Chemicals Company, to leverage NETL's patented work in chemical looping to commercialize an efficient and a cost-effective process for production of hydrogen and carbon from natural gas. This hybrid chemical looping process of production of hydrogen and carbon combined with heat production using an oxygen carrier is a promising technology but finding an appropriate oxygen carrier to perform all the functions has been a challenge. NETL has developed a novel dual function oxygen carrier containing copper oxide - iron oxide. This oxygen carrier in the reduced form functions as catalyst to produce carbon and hydrogen from methane and heat required for this endothermic process is provided by either combustion of hydrogen or oxidation of the reduced oxygen carrier. This process is cost effective, energy efficient and environmental friendly with minimal CO2 mitigation costs. The objective of the project is to obtain data necessary for economic evaluation of the process to produce carbon suitable for applications at Columbian Chemicals Company and Applied Minerals Inc.

Array Effects in Large Wind Farms: Cooperative Research and Development Final Report, CRADA Number CRD-15-590

The effects of wind turbine wakes within operating wind farms has a substantial impact on the overall energy production from the farm. The current generation of models drastically underpredicts the impact of these wakes offshore leading to non-conservative estimates of energy capture and financial losses to wind farm operators and developers. To improve these models, detailed research of operating wind farms is necessary. Cornell University is a world leader of wind farm wakes effects and would like to partner with NREL to help improve wind farm modeling (by gathering additional wind farm data), develop better models and increase collaboration with European researchers working in the same area.

Multifamily Building Stock Modeling: Cooperative Research and Development Final Report, CRADA Number CRD-17-00701

U.S. multifamily buildings house 35 million households, consuming 4 quads of source energy and spending $48 billion on utility bills every year. Almost all of these households live in urban areas, where cities are taking the lead on setting aggressive energy goals. Cities currently do not have the data and tools necessary to identify and target opportunities to save energy in their building stock. Building on the open-source, OpenStudio-based ResStock platform, this project will extend the publicly-available ResStock modeling capabilities to the multifamily sector, enabling Radiant Labs, and others, to partner with cities to market and strategically deploy cost-effective, energy efficiency (EE) upgrades directly to high-priority households. Radiant Labs has been successful in using ResStock's single-family capabilities to provide value to the City of Boulder, Colorado. However, lack of multifamily capabilities in ResStock is a roadblock for Radiant Labs working with New York City, San Francisco, Washington, D.C., and other cities that have expressed significant interest in working with them. In addition, other cities, companies, and utilities can use these open-source capabilities to grow their EE portfolios, thereby multiplying the impact of this project. This work also enables national-scale analysis of EE potential in multifamily buildings, which is of strong interest to a variety of stakeholders, including the U.S. Department of Energy (DOE) Office of Energy Policy and Systems Analysis (EPSA), DOE Weatherization Assistance Program (WAP), U.S. Department of Housing and Urban Development (HUD), and the Bonneville Power Administration (BPA).
