The Thermodynamics of Advanced Fuels - International Database (TAF-ID) project, which has been running for over 10 years, uses the “Calphad” method to develop a thermodynamic database as a computational tool for understanding fuel materials including advanced technology fuels (ATF). This thermodynamic database allows predicting phase diagrams and thermodynamic properties of the phases.
The project also provides a forum for information exchanges, including on thermodynamic models, reviews of experimental data, software evaluation and thermodynamic assessments. TAF-ID brings together 12 participating organisations from Canada, France, Japan, the Netherlands, Sweden, the United Kingdom, the United States and the European Commission.
On 8 July 2025, version 20 of the database was launched to include new and updated assessments in the following materials systems: Al-N, Ba-Cr, Ba-Fe, Cr-H, H-Ni, H-Si, H-U, Al-N-O, C-Cs-O, C-Fe-H, C-O-Si, Fe-H-Si, Np-O-U.
