that utilize alternative feedstocks through multiple levels of maturity and, in some cases, to pre-pilot scale. To accomplish this, the NOFO is divided into two topic areas, each divided into two subtopic areas designed to provide different on-ramps for technologies at different stages of development. Topic Area 1 supports the progression of technologies in the R&D phase. Subtopic Area 1a supports advancing early-stage research to bench scale. Subtopic Area 1b is intended to move projects closer to pre-pilot scale, to a point where critical unit operations must be further developed and demonstrated. Topic Area 2 provides an on-ramp for technologies ready to move from R&D to full pre-pilot scale and operations. Projects applying to Topic Area 2 should aim to advance their technology to design, construct, and operate pre-pilot scale facilities. Both subtopic areas have the same goal—to move technologies into integrated pre-pilot systems and operate them—but allow for two different points of entry. Subtopic Area 2a targets preliminary pre-pilot scale testing of critical unit operations before engineering and design can commence for the entire system while Subtopic Area 2b projects will involve technologies that are ready for design and construction of an integrated pre-pilot facility. Please see the full NOFO document at eere-exchange.energy.gov. Questions regarding the NOFO must be submitted to ASPECT@doe.gov. The required Concept Paper due date for this NOFO is 10/09/2026 at 5PM ET. The Full Application due date for this NOFO is 12/01/2026 at 5PM ET. As stated in the Notice of Intent (search DE-FOA-0003646 in eXCHANGE), a Teaming Partner List has been compiled to encourage collaboration and facilitate the formation of new project teams. Visit: TPL-0000073 Teaming Partner List for DE-FOA-0003646 NOI to Publish DE-FOA-0003647 The eXCHANGE system is currently designed to enforce hard deadlines for Concept Paper and Full Application submissions. The APPLY and SUBMIT buttons automatically disable at the defined submission deadlines. The intention of this design is to consistently enforce a standard deadline for all applicants. Applicants that experience issues with submissions PRIOR to the NOFO Deadline: In the event that an Applicant experiences technical difficulties with a submission, the Applicant should contact the eXCHANGE helpdesk for assistance (exchangehelp@hq.doe.gov). The eXCHANGE helpdesk and/or the EERE eXCHANGE System Administrators (eXCHANGE@ee.doe.gov) will assist the Applicant in resolving all issues. Applicants that experience issues with submissions that result in a late submission: In the event that an Applicant experiences technical difficulties with a submission that results in a late submission, the Applicant should contact the eXCHANGE helpdesk for assistance (exchangehelp@hq.doe.gov). The eXCHANGE helpdesk and/or the EERE eXCHANGE System Administrators (eXCHANGE@ee.doe.gov) will assist the Applicant in resolving all issues (including finalizing the submission on behalf of, and with the Applicant's concurrence). DOE will only accept late applications when the Applicant has a) encountered technical difficulties beyond their control; b) has contacted the eXCHANGE helpdesk for assistance; and c) has submitted the application through eXCHANGE within 24 hours of the NOFO's posted deadline.
