Agency Overview: The Advanced Research Projects Agency Energy (ARPA-E), an organization within the Department of Energy (DOE), is chartered by Congress in the America COMPETES Act of 2007 (P.L. 110-69), as amended by the America COMPETES Reauthorization Act of 2010 (P.L. 111-358), as further amended by the Energy Act of 2020 (P.L. 116-260): (A) to enhance the economic and energy security of the United States through the development of energy technologies that (i) reduce imports of energy from foreign sources; (ii) reduce energy-related emissions, including greenhouse gases; (iii) improve the energy efficiency of all economic sectors; (iv) provide transformative solutions to improve the management, clean-up, and disposal of radioactive waste and spent nuclear fuel; and (v) improve the resilience, reliability, and security of infrastructure to produce, deliver, and store energy; and (B) to ensure that the United States maintains a technological lead in developing and deploying advanced energy technologies. ARPA-E issues this Notice of Funding Opportunity (NOFO) under its authorizing statute codified at 42 U.S.C. 16538. The NOFO and any cooperative agreements or grants made under this NOFO are subject to 2 C.F.R. Part 200 as supplemented by 2 C.F.R. Part 910. ARPA-E funds research on, and the development of, transformative science and technology solutions to address the energy and environmental missions of the Department. 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: http://arpa-e.energy.gov/. 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 develop drive improvements to 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. In 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 better than that of the incumbent technology. ARPA-E will provide support at the highest funding level only for submissions with significant technology risk, aggressive timetables, and careful management and mitigation of the associated risks. 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 clear disruptive potential, e.g., by demonstrating capability for manufacturing at competitive cost and deployment at scale. ARPA-E funds applied research and development (R&D). 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 (defined by the Office of Management and Budget as experimental or theoretical work undertaken primarily to acquire new knowledge of the underlying foundations of phenomena and observable facts ) 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 and Carbon Management (https://www.energy.gov/fecm/office-fossil-energy-and-carbon-management), the Office of Nuclear Energy (http://www.energy.gov/ne/office-nuclear-energy), and the Office of Electricity (https://www.energy.gov/oe/office-electricity). ARPA-E encourages submissions stemming from ideas that still require proof-of-concept R&D efforts as well as those for which some proof-of-concept demonstration already exists. Submissions can propose a project with the end deliverable being an extremely creative, but partial solution. Program Overview: The IGNIITE 2026 program is designed to support a new cohort of early-career innovators to develop the most disruptive and unconventional ideas into transformative new technologies across the full spectrum of energy applications. This announcement is purposefully broad in technical scope, but eligibility is limited to early-career researchers as defined in Section II.A. In addition to research, awardees will engage with ARPA-E, fellow awardees, investors, and other government stakeholders through dedicated events, meetings, and mentorship activities. Submissions to this solicitation must propose transformational R&D that has the potential for high impact. If successful, a project could create a new class or new trajectory for an energy technology, with the potential to substantially contribute to ARPA-E s statutory goals (see Public Law 116 260). Awards under this program may take the form of exploratory research that provides the agency with information useful for the subsequent development of focused technology programs. Alternatively, awards may support proof-of-concept research for a particular new technology in an area not currently supported by the agency.

Improved Oil and Gas Recovery and Produced Water Management Technologies

open

National Energy Technology Laboratory

Modification 000003: The purpose of this modification is to revise NOFO Part 1. Section I.A.1 is revised to correct the Topic Area 1b cost share to 20% and Section IV.C.2 is revised to delete the Environmental Considerations Summary and Environmental Impact Volume from the Summary of Application Requirements table. This Notice of Funding Opportunity (NOFO) will seek proposals for specific research and development (R&D) projects to improve recovery efficiency from unconventional oil and natural gas reservoirs and to advance technologies for the treatment of flowback and produced water from oil and natural gas production operations. Despite increasing energy for demand, recovery efficiency for oil and natural gas from unconventional reservoirs can average less than 10 percent. This NOFO will enable rapid field deployment of a variety of novel technologies and processes related to improving primary and enhanced recovery with the goal of significantly improving resource recovery and accelerating industry uptake. This NOFO will also support the field testing and validation of water treatment technologies of produced water from oil and natural gas production operations to avoid deep well injection and potential issues with induced seismicity and interaction with underground sources of drinking water.
