With hydrazine on the list of "substances of very high concern" by the European Chemicals Agency; hence alternative (storable) liquid rocket propellants are being developed which are less hazardous. During this feasibility study, experiments have been performed with a thermal ignition system in combination with hydrogen peroxide and ethanol as green propellants to achieve ignition followed by self-sustained combustion at the lowest possible power consumption. The experiments have been followed up by a computer model that has been simulated in COMSOL.
