DST Boosts Clean Mobility Push with Type-IV CNG Cylinder Manufacturing Project

Type-IV composite cylinders are considered among the most advanced gas storage technologies currently available globally.

In a major push towards clean energy mobility and advanced indigenous manufacturing, the Technology Development Board (TDB) under the Department of Science & Technology (DST), Government of India, has signed an agreement with Delhi-based NTF Energy Solutions Private Limited to establish a manufacturing facility for next-generation Type-IV Composite CNG Cylinders.

The project marks a significant step in India's efforts to accelerate sustainable transportation infrastructure, reduce carbon emissions, and strengthen domestic capabilities in advanced clean-energy technologies under the Aatmanirbhar Bharat initiative.

The agreement supports the project titled "Establishment of Manufacturing Facility for Commercialization of Type-IV CNG Cylinder," which aims to commercialize cutting-edge lightweight composite gas storage systems designed for India's rapidly expanding compressed natural gas (CNG) mobility ecosystem.

Advanced Manufacturing Facility to Support India's Clean Mobility Transition

Under the project, NTF Energy Solutions will establish an advanced manufacturing facility equipped with state-of-the-art technologies including:

• filament winding systems

• blow moulding technology

• high-pressure testing infrastructure

• composite material processing systems

• advanced quality and safety testing capabilities

The facility will manufacture indigenously developed Type-IV Composite CNG Cylinders intended for use in:

• CNG-powered vehicles

• commercial transportation fleets

• public mobility systems

• clean fuel storage applications

• emerging energy and hydrogen-related sectors

Officials say the project aligns closely with India's broader policy objectives focused on cleaner fuels, reduced fossil-fuel emissions, energy security, and domestic manufacturing self-reliance.

Type-IV Cylinders Offer Major Technological Leap

Type-IV composite cylinders are considered among the most advanced gas storage technologies currently available globally.

Unlike traditional steel cylinders, the new-generation cylinders are built using lightweight composite materials combined with high-strength polymer liners, offering substantial performance advantages.

According to the project details, the indigenous cylinders developed by NTF Energy Solutions can achieve:

• up to 75 percent weight reduction compared to steel cylinders

• improved fuel efficiency in vehicles

• lower overall vehicle emissions

• enhanced operational safety

• longer service life

• improved corrosion resistance

Industry experts say lightweight storage systems are becoming increasingly critical for improving efficiency in alternative fuel vehicles and supporting next-generation mobility technologies.

Indigenous Technology Developed in India

A key highlight of the initiative is that the Type-IV cylinder technology has been developed entirely within India by NTF Energy Solutions Pvt. Ltd.

The cylinders incorporate several advanced engineering features, including:

• corrosion-free polymer liners

• optimized Carbon Fibre Reinforced Polymer (CFRP) layup

• advanced mechanical locking systems

• enhanced vibration resistance

• high-pressure endurance capabilities

• leak prevention technologies

The design reportedly achieves burst pressure resistance exceeding 600 bar, substantially above standard regulatory safety requirements.

Officials say the high-pressure tolerance significantly enhances operational reliability and safety for transportation and industrial applications.

Supporting India's Expanding CNG Ecosystem

India has been aggressively expanding its CNG infrastructure as part of its strategy to reduce dependence on conventional fossil fuels and lower urban pollution levels.

The Government has significantly increased investments in:

• city gas distribution networks

• CNG filling stations

• cleaner transportation systems

• alternative fuel mobility programmes

The rising adoption of CNG-powered commercial vehicles, buses, taxis, and logistics fleets has created growing demand for lighter, safer, and more efficient gas storage systems.

The new project is expected to play an important role in supporting this transition by enabling large-scale domestic production of advanced composite cylinders.

Major Boost for Import Substitution and Manufacturing Self-Reliance

The initiative is also expected to contribute significantly toward reducing India's dependence on imported advanced mobility components.

Officials noted that the project will:

• strengthen indigenous manufacturing capacity

• promote technology self-reliance

• reduce import dependence

• support local supply chains

• encourage advanced materials engineering

• create future-ready manufacturing ecosystems

The facility will utilize locally available raw materials alongside advanced manufacturing processes to create a cost-competitive production environment for high-pressure composite cylinders.

Experts believe the project could help position India as an emerging manufacturing hub for advanced clean-energy mobility components.

Government Highlights Strategic Importance of Advanced Mobility Technologies

Speaking on the occasion, Shri Rajesh Kumar Pathak, Secretary, Technology Development Board, emphasized the strategic significance of commercializing advanced composite cylinder technologies.

"The development and commercialization of advanced Type-IV composite cylinders is important for strengthening India's clean mobility infrastructure and indigenous manufacturing ecosystem," he said.

He further stated that TDB's support reflects the Government's commitment to enabling next-generation technologies that contribute to:

• sustainable transportation

• energy security

• advanced manufacturing

• clean-energy infrastructure

• Aatmanirbhar Bharat objectives

The Government has increasingly focused on supporting deep-technology manufacturing projects capable of strengthening India's position in high-value industrial sectors.

Industry Sees Major Opportunity in Lightweight Composite Technologies

NTF Energy Solutions described the agreement as a major milestone for India's clean-energy manufacturing ecosystem.

Shri Naveen Jain, Managing Director, and Shri Naman Jain, Director of NTF Energy Solutions Pvt. Ltd., expressed gratitude for TDB's support and said the assistance would help accelerate commercialization of indigenous lightweight composite cylinder technologies.

The company stated that the project would contribute to India's transition toward cleaner, safer, and more efficient mobility systems.

Industry observers note that composite cylinder technologies are expected to witness strong global demand growth as countries increasingly adopt cleaner fuels and low-emission transportation systems.

Potential Applications Beyond CNG Mobility

While the current focus remains on CNG transportation, experts say advanced Type-IV composite cylinders could eventually play a broader role in India's emerging clean-energy ecosystem.

Potential future applications may include:

• hydrogen fuel storage

• compressed biogas systems

• industrial gas transportation

• aerospace and defence applications

• energy storage systems

As India moves toward broader decarbonisation goals, lightweight high-pressure storage technologies are likely to become increasingly important across multiple sectors.

Clean Energy Manufacturing Becoming National Priority

The project reflects a broader shift in India's industrial strategy toward combining clean-energy adoption with advanced domestic manufacturing capabilities.

Government initiatives in recent years have increasingly targeted sectors such as:

• electric mobility

• hydrogen technologies

• battery manufacturing

• alternative fuels

• semiconductor production

• advanced materials engineering

Officials say strengthening indigenous innovation and manufacturing capacity in these sectors will be critical to India's long-term economic competitiveness and energy transition goals.

The TDB-backed Type-IV cylinder manufacturing project is expected to contribute to both environmental sustainability and industrial modernization while supporting India's ambition to emerge as a global clean-energy manufacturing hub.
