RFI-0000095: Announcement of Teaming List: Advanced Stimulation and Enhanced Recovery Technologies The Advanced Research Projects Agency — Energy (ARPA-E) is considering issuing a Notice of Funding Opportunity (NOFO) to catalyze transformative breakthroughs in domestic energy and critical minerals extraction.

This initiative aims to achieve step-change improvements by developing and field-validating integrated stimulation and enhanced recovery technologies for low-permeability subsurface formations, reducing both costs and wastewater generation. This Teaming Partner List announcement facilitates the formation of new project teams to respond to the potential NOFO.

Any NOFO issued in the future would provide specific program goals, technical metrics, and selection criteria. If there are any inconsistencies between this announcement and the potential NOFO, the NOFO language would be controlling.

This potential NOFO aims to address persistent technical barriers that impede efficient recovery from diverse low-permeability subsurface resources, including unconventional oil and gas, geothermal energy, and mineral systems.

The program’s goal is to double the per-well recovery efficiency (or recovery factors) of energy and critical minerals from low-permeability formations, while maintaining or reducing both per-unit cost and wastewater volumes relative to state-of-the-art.

Achieving this goal requires innovative approaches to stimulation and enhanced recovery processes supported by rigorous laboratory experiments, numerical modeling, and downhole monitoring. After successful laboratory proof-of-concept, technologies would undergo field validation to ensure a practical path to real-world deployment.

Applicants can choose from one of two categories: Category A (Shale and Tight Oil & Gas) and Category B (Other Low-Permeability Subsurface Resources). ARPA-E anticipates that Category A will comprise the majority of projects selected under this potential program.

Success will not only revolutionize subsurface resource recovery but also contribute to ARPA-E’s goals of reducing foreign energy imports and enhancing energy infrastructure resilience.

Expertise in the following areas may be useful in responding to a potential NOFO: Reservoir, Petroleum, and/or Mining Engineering Chemical Engineering, Chemistry, and Material Science Numerical Modeling and Data Science Sensors and Instrumentation Commercial Deployment (e.g., oil and gas companies, geothermal developers, mining firms with access to field sites, permitting experience) ARPA-E strongly encourages outstanding scientists and engineers from different organizations, scientific disciplines, and technology sectors to form new project teams.

DE-FOA-0003467: Seeding Critical Advances for Leading Energy technologies with Untapped Potential (SCALEUP) Ready The Seeding Critical Advances for Leading Energy technologies with Untapped Potential (SCALEUP) Ready Notice of Funding Opportunity (NOFO) provides a vital mechanism for the support of innovative energy R&D that complements ARPA-E’s primary R&D focus on early-stage transformational energy technologies that still require proof-of-concept.

An enduring challenge to ARPA-E’s mission is that even technologies that achieve substantial technical advancement under ARPA-E support face significant remaining technical and commercial risks upon completion of an award's funding period, and thus are at risk of being stranded in their development path once ARPA-E funding ends.

Experience across ARPA-E’s diverse energy portfolios, and input from a wide range of investors and industry stakeholders, indicates that pre-commercial “scaling” projects are critical to establishing that performance and cost parameters can be met in practice for these potentially transformative technologies.

These pre-commercial scaling projects aim to translate the performance achieved at bench scale to commercially scalable versions of the technology, integrate the technology with broader systems, provide extended performance data, and validate the manufacturability and reliability of new energy technologies.

Success in these scaling projects should enable industry, investors, and partners to justify the substantial commitments of financial resources, personnel, manufacturing facilities, and materials necessary to subsequently deploy the technologies at commercial scale. The objective of SCALEUP Ready is to support the scaling of high-risk and potentially disruptive new technologies across the full spectrum of energy applications.

This NOFO focuses only on scale-up and pre-pilot projects of promising technologies that ARPA-E has previously funded – following highly competitive selection processes – and for which the scale-up award would substantially build upon innovations achieved under the original ARPA-E award. This NOFO will remain open until closed or modified. Applications will be accepted any time while this NOFO remains open.

Full Application Submission Deadline: TBD To access the Teaming Partner List for this announcement, click here . RFI-0000086: Announcement of Teaming Partner List for NOFO: SCALEUP Ready The Advanced Research Projects Agency – Energy (ARPA-E) has issued Notice of Funding Opportunity (NOFO) SCALEUP Ready to support the scaling of promising ARPA-E-funded technologies into early commercial products.

The purpose of this announcement is to facilitate collaboration among potential performing teams to respond to the SCALEUP Ready NOFO. The NOFO provides specific program goals, technical metrics, and selection criteria. NOFO terms are controlling.

The SCALEUP Ready program provides a vital mechanism for the support of innovative energy research and development (R&D) that complements ARPA-E’s primary focus on early-stage transformational energy technologies that still require proof of concept. ARPA-E intends for this NOFO to remain open until closed or modified. Applications will be accepted at any time while this NOFO remains open.

ARPA-E’s mission is to develop and deploy transformational energy technologies in support of U.S. national security and economic competitiveness goals. ARPA-E funds the R&D of energy technologies that, among other goals, reduce imports of energy from foreign sources; reduce energy-related emissions, including greenhouse gases; and improve the energy efficiency of all economic sectors.

ARPA-E’s authorizing statute directs the Agency to ensure that the U.S. maintains a lead in developing advanced energy technologies through accelerating transformational technological advances that industry by itself is not likely to undertake because of technical and financial uncertainty.

Technologies that achieve substantial technical advancement under ARPA-E support may still face significant technical and commercial challenges upon completion of an award's funding period, and thus are at risk of being stranded in their development path once ARPA-E funding ends.

Experience across ARPA-E’s diverse energy portfolios, and input from a wide range of investors and industry stakeholders, indicate that pre-commercial scaling projects are critical to establish practical performance and cost parameters.

These pre-commercial scaling projects aim to 1) translate the performance achieved at bench scale to commercially scalable versions of the technology, 2) integrate the technology with broader systems, 3) provide extended performance data, and 4) validate the manufacturability and reliability of new energy technologies.

Successful scaling projects should enable industry stakeholders to justify the substantial commitments of financial resources, personnel, manufacturing facilities, and materials necessary to subsequently deploy the technologies at a commercial scale. The SCALEUP Ready program seeks to scale the most promising technologies previously funded by ARPA-E.

The possibility of ARPA-E funded technologies becoming stranded along their development pathways leaves substantial intellectual property developed with American taxpayer dollars vulnerable to adoption by foreign competitors, who capture it for continued development and economic benefit overseas.

This harms national competitiveness, as U.S. industries often fall behind on the development, scaling, and manufacturing of technologies necessary to compete in rapidly evolving global energy markets. Thus, projects selected for the program will meet ARPA-E’s statutory goals by “accelerating transformational technological advances in areas that industry by itself is not likely to undertake because of technical and financial uncertainty.

” ARPA-E strongly encourages different organizations with outstanding entrepreneurial scientists and engineers along with commercialization and financial entities across diverse sectors to participate in this program.

Interdisciplinary and cross-sector collaboration spanning organizational boundaries enables and accelerates the achievement of scientific and technological outcomes that were previously viewed as extremely difficult, if not impossible.

ARPA-E is compiling a Teaming Partner List for SCALEUP Ready as an optional tool that applicants may choose to utilize to facilitate the formation of new project teams and identify possible collaborations. Teaming Partners include organizations and individuals who can offer expertise, facilities, or other complementary resources toward a potential ARPA-E project.

The teaming list includes fields for potential partners’ capabilities and areas of interest, understanding that expertise in one field can often be applied successfully to another field. The Teaming Partner List is being compiled to facilitate the formation of new project teams. ARPA-E intends to make the Teaming Partner List available on ARPA-E eXCHANGE ( http://arpa-e-foa.
