STL [NSE: STLTECH], a global leader in optical and digital network solutions, has taken a groundbreaking step in sustainable manufacturing by partnering with Hygenco Green Energies to commission Maharashtra’s first green hydrogen and oxygen production facility dedicated to optical fibre production.
The new facility, located at STL’s state-of-the-art glass preform plant in Chhatrapati Sambhaji Nagar, marks a global first—STL will now become one of the world’s only optical fibre manufacturers to operate using 100% green hydrogen in its production processes. This move is part of STL’s broader commitment to achieving Net Zero emissions by 2030.
Under the 20-year agreement, Hygenco will build, own, and operate the green hydrogen plant, ensuring long-term, commercially viable supply of green hydrogen and oxygen for STL’s operations.
“By leveraging 100% green hydrogen in glass preform manufacturing, we are setting a new global benchmark for decarbonisation in the optical fibre industry,” said Rahul Puri, CEO – Optical Networking Business, STL. “This collaboration exemplifies our commitment to sustainability, innovation, and operational excellence.”
Green hydrogen and oxygen are essential for optical fibre manufacturing, acting as fuels in high-temperature furnaces that convert silica into glass. STL’s semiconductor-grade preform plant, an Industry 4.0-enabled facility, now features autonomous energy management systems, real-time monitoring, and advanced automation—enhancing both safety and efficiency while cutting carbon emissions by approximately 30% annually.
“Green hydrogen is poised to be a catalyst in India’s clean energy transition,” added Amit Bansal, CEO of Hygenco Green Energies Pvt. Ltd. “Our long-term partnership with STL is a bold step toward decarbonising industrial processes and positioning India as a global hub for green manufacturing.”
