Materials Research and Development: Enabling Materials Technologies to Meet Vehicle Technologies Office Goals The U.S. Department of Energy’s Vehicle Technologies Office (VTO) is pleased to introduce the FY 2013 Annual Progress Report for the Propulsion Materials Research and Development Program. Together with Department of Energy national laboratories and in partnership with universities and private industry across the United States, the Propulsion Materials Program continues to invest in research and development (R&D) that provide enabling materials technologies for fuel-efficient and environmentally friendly commercial and passenger vehicles. This introduction summarizes the objectives and progress of the program in fiscal year 2013. The Propulsion Materials Program actively supports the energy security and reduction of greenhouse emissions goals of VTO by investigating and identifying the materials properties that are most essential for continued development of cost-effective, highly efficient, and environmentally friendly next-generation heavy and light-duty powertrains. The technical approaches available to enhance propulsion systems focus on improvements in both vehicle efficiency and fuel substitution, both of which must overcome the performance limitations of the materials currently in use. Propulsion Materials Program activities include work with national laboratories, industry experts, and VTO powertrain systems (e.g., Advanced Combustion Engines [ACE], Advanced Power Electronics and Electrical Machines [APEEM], and fuels) teams to develop strategies that overcome materials limitations in future powertrain performance. The technical maturity of the portfolio of funded projects ranges from basic science to subsystem prototype validation. Propulsion Materials Program activities are structured to serve as an enabling partner and supporter of the following VTO R&D activities: Hybrid and vehicle systems Energy storage APEEM ACE Fuels and lubricants Projects within a Propulsion Materials Program activity address materials concerns that directly impact critical technology barriers within each of the above programs, including barriers that impact fuel efficiency, thermal management, emissions reduction, improved reliability, waste-heat recovery, and reduced manufacturing costs. The program engages only the barriers that result from material property limitations and represent fundamental, high-risk materials issues. Enabling Advanced Technologies A Propulsion Materials Program activity focuses on key technical deficiencies in materials performance that limit the expanded capabilities of advanced combustion engines, electric-drive systems, and fuels and lubricants. It provides materials R&D expertise and advanced materials testing and development that support the goals of combustion, hybrid, and power electronics development. The program provides enabling materials support for combustion, hybrid, and power electronics development, including the following: 1 Propulsion Materials FY 2013 Progress Report Materials for high-efficiency combustion strategies such as homogenous-charge compression ignition Materials for 55% thermal efficiency for heavy-duty diesel engines Materials for waste-heat recovery using mechanical (such as turbo compounding) and solid-state approaches, with the potential for a 10% increase in fuel efficiency Materials technologies for effective reduction of tailpipe emissions, including diesel particulate filters, low-temperature catalyst development, characterization and testing, and exhaust gas recirculation coolers Materials technologies for electric and hybrid-electric vehicles, including thermal management of advanced power electronics materials and reducing dependence on rare earth elements in electric motors Materials for alternate-fuels, including engine and exhaust aftertreatment materials compatibility and corrosion in biofuels Support for the Materials Genome Initiative through identifying effective computational approaches and tools to accelerate the development and deployment of new materials with improved properties. The program supports these core technology areas by providing materials expertise, testing capabilities, and technical solutions for materials problems. The component development, materials processing, and characterization that the program provides are enablers of the successful development of efficient, durable, and emissions-compliant engines. Program Organization The Propulsion Materials Program consists of the following four R&D projects, which support VTO propulsion technologies.
