Funding Agency:
Department of Energy

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. For the latest news and information about ARPA-E, its programs and the research projects currently supported, see:

This FOA will only accept applications in prespecified Targeted Topics. Specific areas of interest and relevant deadlines will be posted on the ARPA-E eXCHANGE website ( For your convenience you can subscribe to the ARPA-E mailing list to receive ARPA-E newsletters and news alerts, as well as updates on when new Targeted Topics are posted. 

Each technology specific Targeted Topic announcement will be visible on ARPA-E eXCHANGE as a supporting FOA document. Targeted topic details will only be visible in eXCHANGE while the notice is accepting applications. Once the topic deadline has passed the notice will be taken down and ARPA-E will no longer be accepting applications in that area. ARPA-E will only review applications that are scientifically aligned with the Targeted Topic(s) open at the time the application is submitted.

Areas of Interest

Targeted Topics:

A. Extremely Durable Concretes and Cementitious Materials
Full Application Submission Deadline: 9:30 AM ET, February 18, 2019
ARPA-E is interested in receiving Full Applications in support of advancing extremely durable concretes and cementitious materials. This topic seeks research towards concrete that outlasts conventional concrete, reduces lifetime O&M expenses and their associated energy requirements, and therefore greatly reduces cement/concrete. Work under this program will consist of early stage research.


B. Leveraging Innovations Supporting Nuclear Energy
Full Application Submission Deadline: 9:30 AM ET, February 18, 2019
It is clear that a substantial reduction of construction cost, O&M cost, and construction time, in combination with targeting reactor plant operation for commercial viability, is required to fundamentally enhance the competitiveness and attractiveness of nuclear energy. The ARPA-E MEITNER Program (DE-FOA-0001798)[1] is already investigating several innovative technologies that forward this goal. The purpose of this Targeted Topic is to address key technology gaps in the portfolio.

C. Downhole Tools to Enable Enhanced Geothermal Systems
Full Application Submission Deadline: 9:30 AM ET, February 18, 2019
ARPA-E seeks novel low-cost sensor technologies capable of mitigating risks and lowering costs in EGS development by better characterizing rock formations and fluid enthalpy at depth. Technologies of interest include but are not limited to fiber-optic sensors and enthalpy measurement devices, as well as companion electronics and communications equipment. Successful projects will facilitate reservoir creation and maintenance, reduce unexpected reservoir behavior, and ultimately lower costs associated with EGS. Successful technologies developed for this purpose may also offer side benefits in applications including O&G, subsurface energy/CO2 storage, aerospace and automotive engineering, nuclear energy, and space exploration.

D. Diagnostic Resource Teams to Support the Validation of Potentially Transformative Fusion-Energy Concepts
Full Application Submission Deadline: 9:30 AM ET, April 15, 2019

ARPA-E supports the exploration and development of potentially transformative fusion-energy concepts, with key aims of significantly lowering development costs and accelerating the timeline to commercial fusion energy. Most of the ARPA-E-supported fusion experiments would benefit from definitive diagnostic measurements to firmly establish the level of performance that has been achieved and/or to clearly identify issues if measured performance is worse than expected. In particular, several of these concepts are showing evidence of thermonuclear neutron production that could be consistent with ion temperatures above 1 keV (approximately 10 million degrees K). Measurements of key plasma parameters in these experiments are needed to confirm the observed neutron yields and determine whether they are consistent with thermonuclear plasma conditions. Such measurements would improve our understanding of these concepts and help identify and correct any deficiencies, if necessary. All of the concepts, including those not yet at keV-level temperatures, would benefit from multi-point, spatially and temporally resolved measurements of plasma parameters and their spatial profiles to experimentally infer particle, energy, and magnetic-field transport.

Eligibility Requirements

This FOA is open to U.S. universities, national laboratories, industry, and individuals. 

ARPA-E is not limiting the number of submissions from Applicants. Applicants may submit more than one application to each Targeted Topic attached to this FOA, provided that each application is scientifically distinct.
