In a landmark move toward sustainable energy and circular economy, the CSIR–Indian Institute of Chemical Technology (IICT) has inaugurated a pilot-scale facility that converts 15 tonnes of rice husk per day into green hydrogen and biochar, marking a pivotal advancement under CSIR’s Bio-Refinery Mission.
From Husk to Hydrogen
The plant utilizes catalytic steam gasification, a thermochemical process that breaks down lignocellulosic biomass—specifically rice husk—into hydrogen-rich syngas. This is followed by purification stages to isolate green hydrogen, while the residual carbon is transformed into biochar, a soil-enhancing and carbon-sequestering material.
- Feedstock: Rice husk, a byproduct of India’s vast rice industry, is abundant and underutilized.
- Technology: Advanced catalysts and reactor designs developed by IICT ensure high hydrogen yield and minimal emissions.
- Output: Daily production includes clean hydrogen suitable for fuel cells and industrial use, and biochar for agricultural applications.
Strategic Significance & National Alignment
This pilot plant is not just a scientific feat—it’s a strategic asset in India’s National Green Hydrogen Mission, which aims to produce 5 million metric tonnes of green hydrogen annually by 2030. The initiative supports:
- Decarbonization of hard-to-abate sectors like steel, transport, and chemicals.
- Energy independence, reducing reliance on imported fossil fuels.
- Rural empowerment, by monetizing agro-waste and creating local employment.
Collaborations & Future Scaling
IICT’s pilot complements broader efforts across Telangana and India:
- NTPC Partnership: IICT is collaborating with NTPC to scale green hydrogen production using renewable energy.
- Green Hydrogen Valley: Stakeholder consultations led by RICH and DST envision Telangana as a hub for hydrogen innovation.
- Research Synergy: The project aligns with DST-IITH’s ICMAP consortium, which explores AI-enabled catalyst design and multi-stage hydrogen generation from biomass.
Environmental & Economic Impact
- Carbon Neutrality: Rice husk combustion is carbon-neutral, with emissions reabsorbed in subsequent crop cycles.
- Biochar Benefits: Enhances soil fertility, retains water, and immobilizes contaminants.
- Circular Economy: Converts waste into value, reducing landfill and pollution.
What’s Next?
IICT plans to monitor performance metrics and optimize reactor conditions for commercial scalability. The pilot’s success could pave the way for regional hydrogen hubs, integrating agro-waste valorization with clean energy production.
IICT Hyderabad’s pilot plant is more than a technological showcase—it’s a blueprint for India’s green energy future. By marrying indigenous innovation with national policy, it exemplifies how science can drive sustainability, economic resilience, and global leadership in clean hydrogen. Raja Aditya
