The main activities currently performed for the development of HNF-based propellants are presented. The objectives and approach adopted are described. The results obtained on the HNF decomposition mechanism and on the re- and co-crystallisation of HNF with potential propellant ingredients are presented. The experimental activities for the screening of a number of HNF-based propellant candidates are discussed. Current limitations and open points are identified, and the future steps for consolidating the interest and feasibility of an HNF-based propellant development are indicated.
