STL, a global leader in optical and digital solutions, has achieved a major milestone in sustainable manufacturing by collaborating with Hygenco for Maharashtra’s first green H₂ and green oxygen production facility for optical fiber. The green H₂ project, centered in Chhatrapati Sambhaji Nagar, Maharashtra, will supply green H₂ and oxygen to STL’s glass preform facility.

This green H₂ facility will enable STL to become one of the world’s first optical fiber manufacturers to deploy 100% green H₂ in its production processes and support its goal to achieve net zero by 2030. Hygenco will build, own and operate the facility, ensuring a reliable and commercially viable supply for 20 years.

Speaking on the successful commissioning of the green H₂ plant, Rahul Puri, CEO – Optical Networking Business, STL, said, “By leveraging 100% green H₂ for its glass preform manufacturing, STL is setting a new global benchmark for decarbonization in the optical fiber industry. Our collaboration with Hygenco exemplifies our commitment towards sustainability and operational excellence. We are proud to lead the way in integrating green H₂ into large-scale manufacturing and look forward to continuing our efforts to build a greener, more resilient future for India and the world.”

“Green H₂ has the potential to be a game-changer in India’s journey towards sustainability. Our long-term engagement with STL represents a bold step forward in decarbonizing industrial processes. We are proud to enable STL to lead the global optical fiber industry into a new era of green manufacturing,” said Amit Bansal, CEO, Hygenco Green Energies Pvt. Ltd.

STL’s semiconductor-grade Glass Preform manufacturing facility in Chhatrapati Sambhaji Nagar is Industry 4.0-enabled plant. It focuses on producing Glass Preforms, essential for creating high-quality optical fibers. H₂ and oxygen play a vital role in the optical fiber manufacturing process, serving as fuel in blast furnaces to convert silica particles into glass. Through a strategic green H₂ collaboration with Hygenco, STL aims to reduce carbon emissions by ~30% annually. The plant now features advanced autonomous energy management systems, real-time monitoring, and automated control technologies, enhancing safety and operational efficiency.
