ISRO’s Innovation: Using Semi-Cryogenic Engine Kerosene as Rocket Fuel

Indian Space Research Organisation (ISRO) is known for its cost-effective missions throughout the world. This organisation is rapidly paving its way towards innovation and the latest one is the ongoing development of the semi-cryogenic rocket engines that will use refined kerosene as the jet fuel.


The current fuel utilised is the basic jet fuel that is a combination of liquid hydrogen and liquid oxygen. The main problem with this fuel is that it is very heavy as well as needs to be kept in freezing temperatures of -253°f approximately. The refined kerosene that will be used by the semi-cryogenic engines is lighter than the normal jet fuel and produces more thrust. Therefore, this fuel will not only help in increasing the payload capacity of the carrier from four to six tons, it’ll also help in reducing the cost of keeping the jet fuel in freezing temperatures.


It was claimed by the ISRO researchers that if everything goes according to the plans, ISRO will launch carriers with semi-cryogenic engines by 2021. It was also stated by a spokesperson of ISRO that these engines will be highly efficient and that the spaceships having these engines will be utilized for releasing satellites in the space and also for deep space missions. Space agencies like NASA and ROSCOSMOS are already utilizing this technology. USA’s first commercial space company, SpaceX has also included this technology in their rockets.

Overall we can say that ISRO is slowly moving towards the path of turning into one of the most successful space organisations in the world. With doing new innovations every day, ISRO has established its name as one of the most promising and innovative space Organisations!
