Details

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.

Estimated total programme funding: USD 100000000

Expected number of awards: 275

CFDA number(s): 47.041

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this financial & professional services opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
