In a landmark address at the National Workshop on Hydrogen Fuel Technologies and Future Trends held at Alliance University, Bengaluru, ISRO Chairman Dr. V Narayanan declared hydrogen as the cornerstone of India’s space propulsion and clean energy ambitions. From mastering cryogenic engines to pioneering fuel cell applications, hydrogen is no longer a distant promise—it’s the beating heart of ISRO’s technological evolution.
Here’s a comprehensive breakdown of the announcement, its implications, and the broader hydrogen ecosystem India is building.
1. Hydrogen at the Core of ISRO’s Space Success
- ISRO’s 100th successful mission, the GSLV Mk III launch in January 2025, was powered by a cryogenic stage using liquid hydrogen and liquid oxygen
- Cryogenic propulsion, once denied to India, is now a domain of mastery, with three systems currently flying
- ISRO has achieved global benchmarks in engine development timelines and stage testing:
- First flight using just three engines
- Engine development completed in 25 months (global average: 34 months)
- Stage test completed in 34 days (global average: 10 months)
- The NASA-ISRO NISAR satellite launch featured a high-value Indian-built payload, showcasing India’s leap in space technology
2. Beyond Rockets: Hydrogen’s Expanding Horizon
- Hydrogen’s role extends to aircraft, trains, automobiles, and fuel cells
- In 2010–11, ISRO and Tata Motors collaborated to build a hydrogen fuel cell-powered bus, which was successfully tested
- In June 2025, five hydrogen-powered buses began commercial operations, marking a milestone in clean public transport
- Companies like BHEL and NTPC are actively developing hydrogen systems and gas turbine engines for broader industrial use
3. Fuel Cells and Clean Energy Innovation
- ISRO demonstrated a 100-watt oxygen-based fuel cell in space last year
- A 20-kilowatt version is currently under testing, aimed at powering future space missions and terrestrial applications
- Hydrogen fuel cells offer a clean by-product—pure water—making them ideal for sustainable energy systems
- These innovations align with India’s National Green Hydrogen Mission, launched in January 2023, which aims to produce 5 million metric tons of green hydrogen by 2030
4. Safety and Sensor Technology: A Critical Focus
- Dr. Narayanan emphasized the need for advanced hydrogen sensors, warning that hydrogen flames are colorless and pose serious safety risks
- Current sensors have a 3–4 second response time; ISRO is pushing for millisecond-level detection to prevent accidents in large-scale hydrogen facilities
- Safety protocols and sensor innovation will be key to scaling hydrogen infrastructure across sectors
5. National Green Hydrogen Mission: A Strategic Push
- The mission focuses on indigenous technology development, infrastructure for storage and transport, and utilization across industries
- With over ₹8 lakh crore in projected investments, the initiative is expected to create 6 lakh jobs by 2030
- India aims to become a global leader in green hydrogen production and export, reducing dependence on fossil fuels and driving sustainability
Closing Thought: Hydrogen as India’s Launchpad to Leadership
Dr. V Narayanan’s remarks underscore a pivotal shift—hydrogen is no longer just a fuel, but a strategic enabler of India’s space ambitions and clean energy future. From cryogenic breakthroughs to commercial buses, ISRO’s hydrogen journey reflects a fusion of innovation, resilience, and vision. As India accelerates toward a hydrogen-powered economy, the message is clear: the future isn’t waiting—it’s already lifting off.
