ARPA-E focuses on next-generation energy innovation to create a sustainable energy future. The agency provides R&D support to businesses, universities, and national labs to develop technologies that could fundamentally change the way we get, use, and store energy. Since 2009, ARPA-E has provided approximately $2 billion in support to more than 800 energy technology projects. Last month, we introduced a new series to highlight the transformational technology our project teams are developing across the energy portfolio. Check out these projects turning ideas into reality.

Newest ARPA-E Program Director Dr. Robert (Bob) J. Ledoux’s professional experience ranges from professor to entrepreneur and his patents from nonintrusive cargo inspection to medical technologies. Recently we had a chance to visit with Dr. Ledoux to discuss how he will bring his experience to bear to further ARPA-E’s mission.

Here at ARPA-E, we’re constantly looking for new white space where we can innovate American energy technologies to increase efficiency and decrease emissions. How people get around has always been an area of interest to us. For instance, we’ve launched programs focused on developing transportation technologies that use smart connected vehicles or alternative power sources and storage technologies for electric motors. Now, our Program Directors are looking at developing transportation programs in a different space – one that has required them to look to the sky.

Every year, convention centers around the world fill with eager attendees looking for a chance to experience firsthand the latest and greatest in the world of automobile innovation. Whether you’re a classic gearhead or technology enthusiast, the auto manufacturers’ annual showcase season is truly a sight to behold. To celebrate car show season, here’s a quick look at some of ARPA-E’s transportation portfolio and a few projects that could one day shape how Americans get around.

Electric propulsion for air vehicles requires a high-power density and high-efficiency electric storage and power generation system that can operate at 35,000 feet in altitude to meet economic and environmental viability. Tennessee Technological University will combine a stack comprised of tubular Solid Oxide Fuel Cells (SOFCs) with a gas turbine combustor to address challenges faced in all electric propulsion-based aviation. The combined SOFC-combustor concept maximizes power density and efficiency while minimizing system complexity, weight, and cost.

Small regional aircraft operations are challenged by high fuel cost, noise restrictions associated with small regional airports, and high maintenance cost of twin gas turbines. A battery/gas turbine hybrid series small regional aircraft, enabled by ULTRA COMPACT driven propulsors, addresses these issues, and could reduce passenger mile energy consumption.

The CO-POWER project will enable a commercial narrow body electric aircraft by developing an ultra-efficient and lightweight fuel to electricity power generation system that includes the use of supercritical carbon dioxide (sCO2) as a working fluid. The proposed approach combines decades of knowledge in gas turbine engines with novel advances in additive manufacturing research and sCO2 power generation experience to increase the overall power system efficiency and its power density.

Precision Combustion (PCI) is proposing an advanced energy storage and power generator design for meeting aggressive specific power and energy targets for all-electric propulsion of narrow-body commercial aircraft. Key enablers are an exceptionally power-dense solid oxide fuel cell system operating with energy-dense carbon neutral liquid fuels and a hybridized system architecture that maximizes component efficiencies for ultra-high system efficiency. PCI will validate compliance via component demonstration and develop a verifiable model for scale-up.

Fuceltech proposes to develop an innovative low-cost, lightweight Energy Storage and Power Generation (ESPG) system for commercial aircraft. Fuceltech will develop a monopolar wound single fuel cell potentially as high as 10 kW rating and a novel stacking approach to deliver hundreds of kWs of power from a single small and lightweight stack. Fuceltech will use ethanol as a fuel and a reformer that delivers extremely low CO concentration in the reformate to the fuel cell.
