STL and Hygenco Spark Sustainability Revolution in Optical Fibre

In a pivotal moment for sustainable manufacturing, STL (Sterlite Technologies Ltd) and Hygenco Green Energies have launched Maharashtra's first green hydrogen and oxygen plant to power STL's optical fibre preform plant in Chhatrapati Sambhaji Nagar.

This landmark project, dubbed Photon Leap, is historic, and enables STL to become one of the first three optical fibre manufacturers in the world to use green hydrogen as part of the manufacturing process.

The facility is operated under a build-own-operate model and was inaugurated on 17 July 2025, and provides Hyderabad guarantees, green hydrogen and oxygen supply for the next 20 years. For Hygenco, the collaboration is their third commercial plant after similar projects in Ujjain and Hisar, as Hygenco ramps the company's vision to install 10 GW of green hydrogen capacity by 2030.

The plant is a technological leap forward, equipped with autonomous energy management systems, real-time monitoring, and AI-driven safety controls. It enables STL to reduce its annual carbon footprint by approximately 30%, aligning perfectly with the company’s Net Zero by 2030 ambition.

This breakthrough not only reinforces STL’s commitment to climate responsibility but also sets a global industry benchmark in clean-tech adoption for fibre optic production. As green hydrogen gains traction in industrial applications, STL and Hygenco's partnership is a transformational blueprint for decarbonizing India’s manufacturing sector—signaling a bold shift toward cleaner, future-ready infrastructure.
