The University of Illinois is the lead institution in creating a national archive database for alternative jet fuels. The database was developed as part of the Federal Aviation Administration's (FAA) Aviation Sustainability Center of Excellence (ASCENT) program, and aims to consolidate properties and combustion test data for current and emerging alternative jet fuels into a single archive—with the goal of providing a single point of information to aid fuel design, optimization, and testing that meet operational requirements for jet engine combustion.
