Renewable Biofuels for a Cleaner Tomorrow
Sai Bioenergy’s Renewable Biofuel platform begins with carefully selected feedstock. It continues through advanced conversion and purification. Our process creates clean fuel and by-products like biofertilizer, Carbon-dioxide and Sulphur. New value is created for agricultural communities.
Our Bikaner, Rajasthan plant produces 10 tonnes per day (TPD) Compressed Biogas for real-world energy applications. Plants at Maharashtra, Chatthisgarh, Telangana, Karnataka and Ghana, internationally, are also under development.
What Powers a Cleaner Future?
Renewable Biofuels are transforming the way the world produces and consumes energy. Unlike fossil fuels, they are produced from renewable biomass. They help reduce greenhouse gas emissions while making productive use of agricultural residues and dedicated energy crops. At Sai Bioenergy, we are building a diversified renewable fuel portfolio designed to meet today’s energy needs while preparing for tomorrow’s low-carbon economy.
Compressed Bio Gas
High-purity biomethane produced from organic biomass. Undergoes advanced anaerobic digestion and upgrading technology. A cleaner alternative for transportation, industrial heating and commercial energy applications.
Liquefied Bio-Methane
Renewable biomethane in liquefied form. Useful for long-distance transportation and high-energy-demand applications. Offers greater storage and transport efficiency.
Renewable DME
A next-generation clean fuel for industrial heating, commercial cooking and transport. Provides a low-emission alternative to LPG and diesel.
Green Methanol
A renewable, low-carbon fuel. It is the first, matriarchal fuel from which other renewable biofuels can be created.
Sustainable Aviation Fuel
Sai Bioenergy is developing a biomass-to-methanol-to-SAF pathway. This approach can convert agricultural biomass into valuable aviation fuel.
Future Green Molecules
Ongoing research into next-generation renewable fuels. They will support hard-to-abate sectors and accelerate the global energy transition.
Turning Biomass into Useful Energy
Renewable biofuels are made from biological resources. These resources include agricultural residues and Energy Crops. They can replace fossil fuels across mobility, industry and commercial energy. They can also create new value from materials that farmers already produce through the 3F™ Circular Impact Model – Feedstock to Fuel to Fertilizer.
Our current focus is high-purity Compressed Biogas. Our wider platform includes Liquefied Biomethane, Green Methanol, Renewable DME and Sustainable Aviation Fuel. Our research programme also covers future green fuels and bio-based chemicals.
Compressed Biogas (CBG) – A Direct Replacement to Compressed Natural Gas (CNG)
Compressed Biogas is purified biomethane. It has the same core fuel application as Compressed Natural Gas. Since CBG has a similar if not greater calorific value as CNG, it is also known as Bio-CNG.
CBG also reaches wider markets through gas companies and Oil Marketing Companies (OMCs). These routes include organisations such as GAIL, Gassonet, Torrent etc,. They can connect CBG with customers beyond our direct logistics network. CBG gives customers a renewable fuel option within familiar CNG systems.
Who Uses Compressed Biogas (CBG)? Connecting Renewable Fuel With Real Customers
Mobility
CBG can fuel cars, buses, trucks and commercial vehicle fleets. It can serve customers who already use CNG. It can support cleaner transport without changing the basic fuel application.
Cooking & Industrial Energy
CBG can enter PNG networks for home or commercial cooking. It can support pipelined connections at homes, hotels, restaurants, institutions and food-processing facilities.
For industries, CBG can support boilers, furnaces, dryers and process heating.It can serve industries that currently use natural gas or other fossil fuels.
Gas & Oil Marketing Companies (OMCs)
Gas companies can distribute CBG through pipeline networks. Oil marketing companies can distribute CBG through retail outlets. Logistics companies can transport CBG through cylinder cascades.
These channels expand market access and improve evacuation capacity.
CBG and Gobar Gas – Different Feedstocks. Different Purity. Different Uses.
Sourcing the Feedstock is the most important step of the process of manufacturing Compressed Bio Gas (CBG). CBG can be manufactured from agricultural waste residue (paddy, wheat, corn etc.), Energy Crops (Napier Grass, Maize, Sorghum etc.), organic fraction of municipal waste and animal waste like cow dung.
The usage of different feedstock material can affect the purity of CBG as each material has different methane content and the process of purifying is also different.
Biogas and CBG: When feedstock undergoes anaerobic digestion, the resultant gas is made of 45-50% Methane, 40% Carbon Dioxide and gases like Nitrogen, Hydrogen Sulphide (impurities) etc. This raw gas that has not been purified is known as Biogas. When this raw Biogas undergoes purification where Carbon Dioxide, Nitrogen, Hydrogen Sulphide and other by-products are removed, pure Compressed Bio Gas (CBG) is obtained.
Gobar gas and CBG: When cow dung is used as feedstock, the resultant raw biogas that has not been purified is called Gobar gas. This can only be used for cooking. While CBG is the highly purified form that be used as fuel for vehicles. However, the feedstock source can vary.
Paddy Straw
Paddy straw has high levels of carbon, cellulose, hemicellulose, and lignin, which hold stored chemical energy that releases heat or creates gas when processed. Millions of tons of rice straw are left over after every harvest, creating a steady and abundant local supply of raw material.
Napier Grass
Napier Grass produces a massive amount of fast-growing biomass rich in fermentable sugars and fibres that convert efficiently into biofuels like CBG and electricity. It matures quickly and allows for 4 to 6 multiple harvests (cuts) per year, an additional farmer income.
Maize Stalks
Maize is a C4 plant that converts sunlight and carbon dioxide into organic matter very efficiently, leaving behind massive quantities of post-harvest stalk residue. They produce high amounts of fibrous biomass rich in cellulose, hemicellulose, and lignin that can be converted into Biofuels.
Biomass Sorghum
Grows up to 20 feet tall in a single season. Farmers grow it for its massive yield of stems and leaves which are burned or converted into cellulosic biofuels. It survives and thrives in dry areas.
Sai Bioenergy 3-step Membrane Purification for CBG
- Sai Bioenergy’s 10 TPD CBG plant in Bikaner, Rajasthan, produces Compressed Bio Gas (CBG) of purity >= 98%, unparaled in the market.
- It undergoes an intense purification process where impurities like Carbon Dioxide (CO₂), Nitrogen (N₂), Hydrogen Sulphide (H₂S) are removed.
- The H₂S Scrubbing system, Sulfa Clean of our partner, Atrium Innovations, is a captive technology.
A three-membrane purification system removes further impurities.
