ARPA-E funds research on and the development of high-potential, high-impact energy technologies that are too early for private-sector investment.

The agency focuses on technologies that can be meaningfully advanced with a modest investment over a defined period of time in order to catalyze the translation from scientific discovery to early-stage technology.

ARPA-E funds transformational research.

Existing energy technologies generally progress on established “learning curves” where refinements to a technology and the economies of scale that accrue as manufacturing and distribution to develop drive down the cost/performance metric in a gradual fashion.

This continual improvement of a technology is important to its increased commercial deployment and is appropriately the focus of the private sector or the applied technology offices within DOE.

By contrast, ARPA-E supports transformative research that has the potential to create fundamentally new learning curves.

ARPA-E technology projects typically start with cost/performance estimates well above the level of an incumbent technology.

Given the high risk inherent in these projects, many will fail to progress, but some may succeed in generating a new learning curve with a projected cost/performance metric that is significantly lower than that of the incumbent technology.

ARPA-E funds technology with the potential to be disruptive in the marketplace.

The mere creation of a new learning curve does not ensure market penetration.

Rather, the ultimate value of a technology is determined by the marketplace, and impactful technologies ultimately become disruptive – that is, they are widely adopted and displace existing technologies from the marketplace or create entirely new markets.

ARPA-E understands that definitive proof of market disruption takes time, particularly for energy technologies.

Therefore, ARPA-E funds the development of technologies that, if technically successful, have the clear disruptive potential, e.g., by demonstrating capability for manufacturing at competitive cost and deployment at scale.

ARPA-E funds applied research and development.

The Office of Management and Budget defines “applied research” as an “original investigation undertaken in order to acquire new knowledge…directed primarily towards a specific practical aim or objective” and defines “experimental development” as “creative and systematic work, drawing on knowledge gained from research and practical experience, which is directed at producing new products or processes or improving existing products or processes.” Applicants interested in receiving financial assistance for basic research should contact the DOE’s Office of Science (http://science.energy.gov/).

Office of Science national scientific user facilities (http://science.energy.gov/user-facilities/) are open to all researchers, including ARPA-E Applicants and awardees.

These facilities provide advanced tools of modern science including accelerators, colliders, supercomputers, light sources and neutron sources, as well as facilities for studying the nanoworld, the environment, and the atmosphere.

Projects focused on early-stage R&D for the improvement of technology along defined roadmaps may be more appropriate for support through the DOE applied energy offices including:
the Office of Energy Efficiency and Renewable Energy (http://www.eere.energy.gov/), the Office of Fossil Energy (http://fossil.energy.gov/), the Office of Nuclear Energy (http://www.energy.gov/ne/office-nuclear-energy), and the Office of Electricity Delivery and Energy Reliability (http://energy.gov/oe/office-electricity-delivery-and-energy-reliability).

Program Overview:
The Aviation-class Synergistically Cooled Electric-motors with iNtegrated Drives (ASCEND) program supports the development of novel lightweight and ultra-efficient electric motors, drives , and associated thermal management system (collectively referred to as the all-electric powertrain) that will facilitate net-zero carbon emissions in the single-aisle, 150-200 passenger commercial aircraft segment.

This FOA represents part of a wider ARPA-E effort in the development of enabling technologies for long-range (≥ 2,800 nautical miles), carbon neutral commercial aviation.

The other part of the wider ARPA-E effort is included in a separate FOA targeting ultra-efficient and lightweight energy storage and fuel-to-electric power conversion system .

The overarching goal of the two FOAs is to reduce the emissions from commercial aviation by developing cost-competitive systems for the efficient conversion of the chemical energy of carbon-neutral liquid fuels (CNLFs) to delivered electric energy, which is then further converted to thrust via propulsors driven by electric motors and associated motor drives.

The focus of the ASCEND program is the development of an all-electric powertrain as the prime mover for long-range, narrow-body aircraft such as the Boeing 73 7.

Current electric powertrains do not have high enough power density and efficiency to enable competitive and fully decarbonized aviation for the narrow-body class of aircraft.

The ASCEND program aims to take advantage of emerging materials, manufacturing techniques, and design topologies, with a focus on the co-design of electromagnetics, power electronics, and thermal management solutions.

The ASCEND program requires demanding figures of merit for specific power ( 12 kW/kg) and efficiency ( 93%) for the fully integrated all electric powertrain systems; these targets, among others, are well beyond the capability of current state of the-art technologies and will require creative thinking and innovation in the electric motor and power electronics space.

The ASCEND program will incorporate two phases.

Phase I calls for conceptual designs and computer simulations of motor, its drive, and their integration, as well as subsystem/component level demonstrations, as necessary, for the proposed key enabling technologies to support the design and simulated performance projections.

Phase I will be 18 months long.

Subject to the availability of appropriated funds, projects that achieve technical success in Phase I may, at ARPA-E’s sole discretion, proceed to the second phase of the program to develop, fabricate, and test an integrated motor and drive developmental prototype (≥ 250 kW) comprised of an electric motor, its drive and associated thermal management system (TMS).

If successful, the ASCEND program will accelerate innovations and cause disruptive changes in the emerging electric aviation field, which is poised to play a significant role in the near- and long-term.

The program will also further enhance the U.

S.

technology dominance in the field of high-performance electric motors for hybrid electric aviation and a full range of other industrial applications beyond aviation, such as electric vehicles, maritime technologies, wind turbines, and off-shore drilling.
