Andhra Sugars Ltd has started supply of liquid hydrogen, cryogenic fuel to the Indian Space Research Organisation (ISRO).

Liquid hydrogen is used as a propellant in the Geostationary Satellite Launch Vehicle (GSLV) by the national space agency.

GSLV is used in placing bigger satellites in a stationery orbit. India is testing its capabilities in this area. The liquid hydrogen tanker was flagged off by Mr S. Ramakrishnan (Director – LPSC) and Mr P. Narendranath Chowdary, Joint Managing Director of Andhra Sugars today from the Tanuku plant.

According to Mr Chowdary, the company has set up a facility to liquefy hydrogen gas with the technical guidance from ISRO.

In ISRO's satellite launch vehicle's solid propellant is used in the first stage, liquid propellant in the second stage and cryogenic propellant in the third stage of GSLV. All these propellants are now manufactured by Andhra Sugars.

The Tanuku-headquartered company has been supplying propellant's to the ISRO for some time as part of its national commitment and indigenous technology capability demonstration.
