Renewable Biofuels
Convert agricultural biomass into Compressed Biogas (CBG), Renewable DME and future renewable fuels through advanced circular resource management.
The Future Cannot Wait
Building Tomorrow's
Circular Energy Ecosystem
The future of energy isn't built by a single technology — it's created through connected solutions. Sai Bioenergy develops integrated renewable biofuels, long-duration battery energy storage and circular resource management solutions that transform agricultural biomass into clean energy, strengthen energy security and accelerate the transition towards a Net Zero future.

Who we are
Engineering tomorrow's energy ecosystem
Sai Bioenergy is a renewable energy company committed to accelerating the transition towards a cleaner and more sustainable future. As part of the Atri Energy Transition ecosystem, we combine expertise in biofuels, long-duration energy storage, sustainable agronomy and engineering to develop integrated energy solutions that address some of the world's most pressing energy and environmental challenges.
Our approach extends beyond producing renewable fuels. We build interconnected systems that strengthen energy security, enable circular resource utilisation, support rural livelihoods and contribute towards a low-carbon future.

Our approach
Every energy transition begins with a resource
Every day, valuable agricultural biomass is left unused or burned. At Sai Bioenergy, we see renewable energy waiting to happen. Through our 3F™ Circular Impact Model, agricultural residues become renewable biofuels, nutrients return to farms as biofertilizer and cleaner energy creates stronger communities.
Feedstock
Agricultural residues and energy crops, responsibly sourced
Fuel
CBG, LBM and renewable DME for transport and industry
Fertilizer
Nutrient-rich biofertilizer returned to the soil

What we do
Two technologies.
One shared mission.
Sai Bioenergy develops integrated clean energy solutions by combining renewable biofuels and long-duration battery energy storage. Together, these technologies help industries reduce emissions, improve energy resilience and accelerate the global transition towards a low-carbon future.
Energy Storage
Deploy Vanadium Redox Flow Battery (VRFB) technology for safe, scalable and long-duration Battery Energy Storage Systems (BESS).
Looking ahead
Future technologies
Ongoing research into next-generation renewable fuels and intelligent energy systems — green methanol for marine and chemical markets, AI-enabled energy management, virtual power plants and emerging long-duration storage chemistries that will support hard-to-abate sectors.
- Green Methanol
- Future Green Molecules
- AI Energy Management
- Virtual Power Plants
- Grid Flexibility
Technology
The platforms behind the portfolio
Proven process technology, engineered for Indian feedstock and Indian operating conditions — then extended into storage and carbon markets.
DRANCO
Dry anaerobic digestion for high-solids feedstock — a small footprint, low operating cost route to biogas from agricultural residue.
Liquefaction
Cryogenic upgrading to Liquefied Bio-Methane, creating a virtual pipeline for long-distance transport and high-demand industrial users.
BESS
Vanadium and organic flow battery systems delivering safe, long-duration storage with exceptional cycling life and 30+ year design life.
Carbon Credits
Measurable, auditable emissions reduction from displaced fossil fuel and avoided residue burning — structured for carbon market participation.
