Green Fuel-HAN

The Indian space agency, ISRO (Indian Space Research Organisation), has been developing an environment-friendly propellant to power Indian satellites and spacecrafts. This ‘green fuel’ is meant to replace the usual hydrazine fuel mixture, which is known to be toxic and the carcinogenic chemicals.

• Scientists from ISRO’s Liquid Propulsion Systems Center (LPSC) have been experimenting with a new propellant blend that’s based on hydroxy lammonium nitrate (HAN). The reason hydrazine is usually preferred for fuel is because of its high performance.
