Clarke Energy, a Rehlko company, has successfully commissioned its first membrane-based biogas upgrading plant in India, marking a significant milestone in the country’s clean energy transition. The facility is located at a municipal solid waste anaerobic digestion site operated by Srinivas Waste Management Services Private Limited (SWMS) in Chetpet, Chennai.
The SWMS site processes biodegradable organic food waste from the surrounding region, converting it into biogas and soil improver—delivering meaningful sustainability benefits to the local community.
This project directly supports India’s SATAT (Sustainable Alternative Towards Affordable Transportation) initiative, which aims to establish 5,000 bio-CNG plants nationwide. Clarke Energy’s membrane-based upgrader offers a scalable, efficient, and locally manufactured solution to meet these ambitious targets.
Building on Clarke Energy’s 30-year presence in the Indian biogas sector, this project showcases the company’s capability to deliver advanced renewable gas solutions that support India’s circular economy. The new system replaces a pressure swing adsorption (PSA) unit with a membrane-based purification system capable of upgrading 600 Nm³/hr of raw biogas into high-purity biomethane.
The integrated solution includes a biogas dryer, scrubber, low-pressure compressor, two-stage membrane separation system, and complete instrumentation and interconnection piping. Key components were sourced locally, ensuring competitive delivery timelines and sustainability benefits. Initial commissioning results confirm the system is meeting guaranteed performance levels at part load, with methane purity exceeding 97.4%, while minimizing methane losses.
“This project marks the first biogas upgrader system fully designed, developed, and manufactured in India by Clarke Energy. It’s a significant milestone for our Indian operations by demonstrating how we’re combining international expertise with local execution to deliver state-of-the-art renewable gas solutions that support India’s clean energy future,” said Kyle Quinn, President, Clarke Energy.
Clarke Energy’s membrane-based upgrader offers higher methane recovery, potentially lower operational costs, and modular scalability – making it ideal for urban waste-to-energy applications.
