Hygenco India to supply green hydrogen to optical firm STL

India-based Hygenco has sealed a long-term off-take contract to supply green hydrogen to the manufacturing plants of local optical and digital technology firm Sterlite Technologies Ltd (NSE:STLTECH), or STL.

Under the agreement, Hygenco will build, own and operate a new green hydrogen facility for STL for 20 years. The site is expected to become operational in the next 15-18 months, STL said on Thursday.

STL needs hydrogen as a key component in the production of optical fibre. The gas is used as fuel in blast furnaces to produce glass from silica particles.

The partnership with Hygenco will see the replacement of STL’s current electrolysers running on conventional energy with renewable energy-based ones installed by Hygenco. This will allow the optical fibre manufacturer to advance its decarbonisation efforts, reducing its carbon emissions by about 30% year-on-year.

This agreement reached is described as the very first green hydrogen project in India's optical industry. It is aligned with STL's Net-Zero by 2030 strategy.
