Summary of Program Requirements Engineering (ENG): Chemical, Bioengineering, Energy, and Transport Systems (CBET) The U.S. National Science Foundation Directorate for Engineering (NSF ENG) supports foundational engineering research for chemical, bioengineering, energy, and transport systems through the following programs: The Chemical Process Systems (CPS) program supports foundational engineering research in chemical and biochemical processes for chemicals, fuels, energy, and materials.

The Engineering Biological and Biomedical Systems (EBBS) program supports foundational engineering research on platforms, devices, organisms, tissues, and processes that advance knowledge and control of biological functions. The Energy, Water, and Resource Engineering (EWRE) program supports foundational engineering research to manage energy, water, minerals, and material resources.

The Transport Phenomena (TP) program supports foundational engineering research to understand, model, and control the transport of mass, momentum, energy, and species across multiple scales. NSF ENG anticipates a portfolio of ENG: Chemical, Bioengineering, Energy, and Transport Systems (CBET) awards with a range of budgets and durations.

Estimated program budget, number of awards, and average award size/duration are subject to the availability of funds. NSF ENG is particularly interested in intellectually ambitious and potentially transformative foundational research. Proposals need not promise a near-term product, deployment, or commercial outcome, nor need they address later-stage development to be competitive.

The U.S. National Science Foundation (NSF) supports foundational research that leads to scientific breakthroughs and opens new frontiers of human knowledge. NSF investments in scientific discovery underpin technological innovation across industries, strengthening U.S. economic competitiveness, enhancing national security, and improving quality of life for all Americans.

NSF's priority under this funding opportunity is to advance foundational research, spanning both incremental advances that build systematically on prior scholarship and bold, high-risk inquiries capable of reshaping entire fields.

NSF places particular emphasis on projects that challenge prevailing paradigms, ask important questions, develop new theories or methods, create research tools or datasets that enable further research, or open new lines of inquiry. Proposals need not promise a near-term product, deployment, or commercial outcome, nor must they address later-stage development in a named technology priority to be competitive.

NSF further recognizes that the most consequential discoveries increasingly emerge at the boundary between disciplines, and it therefore strongly encourages proposals that forge novel connections across scientific domains.

Within this mandate, NSF is especially interested in intellectually ambitious and potentially transformative research; work that creates opportunities for exceptional early-career investigators; and proposals that leverage emerging technologies, including AI, advanced computation, and automation, to make new modes, methods, or scales of science possible. The use of these tools should be scientifically justified rather than incidental.

Beyond accelerating existing workflows, such tools open fundamentally new scientific questions, reveal patterns invisible to prior methods, and enable experimental and analytical capabilities. To support this vision, NSF seeks proposals spanning a wide range of funding levels and project durations.

NSF is working to expand opportunities at both ends of this spectrum, including rapid grants that allow researchers to quickly test exploratory ideas and longer, larger awards that provide sustained support for ambitious, transformative research. For preliminary or time-sensitive work, NSF encourages investigators to use mechanisms such as Planning Proposal, RAPID, EAGER, and RAISE (see Chapter II. F of the PAPPG for more information).

Where longer awards would benefit the pursuit of ambitious, transformative research and reduce administrative burden on investigators, NSF encourages proposals requesting up to five years of support. Investigators may consider the options above, and others, outside of the project sizes and durations specified in this funding opportunity.

NSF welcomes submissions from all researchers, particularly those earlier in their careers and those working in the foundational research areas highlighted in the Administration's FY28 Research and Development Budget Priorities Memorandum .

NSF also expects the highest standards of scientific rigor, transparency, reproducibility, research integrity, and adherence to tenets of Gold Standard Science in proposals, as appropriate for the field of science and research modality.

In alignment with the Administration's Fiscal Year 2028 Research and Development Budget Priorities Memorandum, the NSF Directorate for Engineering (ENG): Chemical, Bioengineering, Energy, and Transport Systems (CBET) solicitation supports foundational engineering research that involves the transformation and/or transport of matter and energy by chemical, thermal, or mechanical means.

Through ENG: CBET, the physical, chemical, and biological sciences are integrated in foundational engineering discoveries. The investment delivers the chemical and process engineering that turns laboratory breakthroughs into scalable methods for U.S. industry to grow domestic production in semiconductors, advanced materials, biotechnology, and energy systems.

ENG: CBET investments leverage artificial intelligence (AI) to solve challenging problems in fluid dynamics, chemical process control, advanced materials, synthetic and engineering biology, and energy management.

The solicitation promotes the use of AI as an instrument for discovery when scientifically appropriate, in areas such as quantum biosensors, biomanufacturing, chemical and bioreactor design, and multiphase flow systems that support nuclear technologies. Previous ENG: CBET investment in foundational engineering research has resulted in transformative advances.

NSF-supported recombinant DNA research showed that bacteria could be made to produce certain proteins humans rely on, leading to biosynthetic insulin and helping to launch the modern biotechnology industry. NSF-supported foundational engineering research on how cells attach to and grow within three-dimensional scaffolds resulted in methods used to replace damaged skin and bone.

NSF-supported foundational research in high-performance membranes, electrochemistry, process design, and modeling has led to reverse-osmosis becoming the dominant method for water desalination in the U.S. and the world.

NSF-supported foundational engineering research has also led to new electrochemical methods and the discovery of new high-performance catalysts that together convert agricultural waste into high value chemicals for manufacturing a variety of products and fuels. The ENG: CBET solicitation is managed by the Directorate for Engineering. This solicitation covers submission to the following ENG: CBET programs.

Research that fits within a single program and multidisciplinary research that spans more than one of these programs are welcome.
