Kailash, for the mountain that stands unmoved. Urja, for the energy that moves everything else.
Kailash Urja is an Indian renewable energy company. Our first project is a compressed biogas (CBG) plant fed by napier grass: a perennial energy crop that is fermented in sealed digesters and refined into a fuel that runs cars, trucks and factories.
Nothing is wasted in the process. The digested slurry that remains is fermented organic manure, and it goes back to the same plantations the grass came from.
We are developing our first site now: securing land, establishing napier plantations, completing approvals, and assembling the team and partners to build well.
It starts in the field
Napier grass grows past head height in months, gives several harvests a year, and keeps yielding for years from a single planting. We grow it deliberately, as a crop whose harvest is energy.
From grass to fuel, in four steps
Compressed biogas is not experimental chemistry. It is a proven industrial process, running at hundreds of plants worldwide, that we are pairing with a crop grown for it.
Grow
Napier grass is planted once and harvested for years, several times a year, on plantations around the plant. Each harvest is chopped and ensiled on site, so the digesters are fed year-round.
Digest
Inside sealed anaerobic digesters, microbes break the ensiled grass down over several weeks, releasing raw biogas of roughly 55 to 60 percent methane.
Purify and compress
The gas is scrubbed of carbon dioxide and hydrogen sulphide, upgraded past 90 percent methane, and compressed to 250 bar. It now meets IS 16087, the Indian standard for automotive biogas.
Return
CBG is filled into cascades for fuel stations and industry. The digestate left behind goes back to the plantations as fermented organic manure, closing the loop it started in.
Why compressed biogas
Of every renewable technology we could have started with, CBG is the one that pays farmers, cleans the air and fuels vehicles at the same time.
- Interchangeable with CNG
- Purified past 90 percent methane and compressed to 250 bar, CBG runs in the same vehicles, cylinders and pipelines as CNG, without modification.
- Carbon already in the loop
- The carbon dioxide released when CBG burns was pulled from the air by the grass only months earlier. Diesel adds ancient carbon to the sky; CBG recycles recent carbon through it.
- A crop built for energy
- Napier grass is planted once and harvested for years, and it thrives on land that struggles with food crops. Every acre under it earns steady, contracted income for the farmer who grows it.
- The second product is soil
- Digestion leaves behind fermented organic manure rich in nitrogen, phosphorus and potassium. Returned to farms, it cuts the need for chemical fertiliser.
- Assured national demand
- Under the SATAT initiative, India's oil marketing companies offer long-term offtake agreements for CBG, with a national target of thousands of plants.
- Energy security, locally made
- Every cubic metre of CBG made from Indian fields displaces imported natural gas, and the money for it stays in the district that grew the grass.
What we are building
The first plant
Site development, feedstock agreements and statutory approvals for our first compressed biogas facility.
A plantation network
Napier cultivation with nearby farmers and landowners on long-term terms, so the plant never waits for raw material and the farm never waits for payment.
A renewable portfolio
CBG is where we start, not where we stop. We intend to build and operate a growing portfolio of renewable energy assets, adding capacity where we can run it well.
Compressed biogas, in plain terms
The questions we hear most from landowners, offtakers and investors, answered briefly.
What is compressed biogas (CBG)?
CBG is biogas purified to at least 90 percent methane and compressed to 250 bar, as specified by the Indian standard IS 16087. Its properties are close enough to CNG that the same vehicles, cylinders and pipelines run on either. It is made by fermenting organic material, in our case napier grass, in sealed oxygen-free digesters.
Is CBG the same as bio-CNG?
Yes. Bio-CNG and CBG are two names for the same fuel: purified, compressed biomethane. CNG is compressed fossil gas; CBG matches its specification but comes from plants that grew a few months earlier.
What is the SATAT initiative?
SATAT (Sustainable Alternative Towards Affordable Transportation) is a Ministry of Petroleum and Natural Gas initiative, launched in October 2018, targeting 5,000 CBG plants producing 15 million tonnes a year. Under it, India's oil marketing companies sign long-term CBG offtake agreements with producers. Around 130 plants had been commissioned by early 2026, so the build-out is still early.
Is anyone required to buy CBG?
Yes. The CBG Blending Obligation makes blending mandatory for city gas distribution: 1 percent of CNG and PNG volumes in FY 2025-26, rising to 5 percent from FY 2028-29. Between the obligation and SATAT offtake agreements, demand for CBG is written into policy.
Why napier grass instead of waste?
Waste streams are seasonal, dispersed and contested; a dedicated energy crop is none of those. Napier grass is a perennial planted once and harvested several times a year for years, including on land that struggles with food crops. Growing feedstock around the plant gives the digesters a predictable year-round supply, which is the hardest part of running a CBG plant well.
Can farmers and landowners work with Kailash Urja?
Yes, that is the model. We contract napier cultivation with farmers and landowners near our plant on long-term terms, and the fermented organic manure from the plant returns to those fields. If you have land or grow napier within reach of our site, write to info@kailashurja.com or use the form below.
What stage is Kailash Urja at?
We are developing our first plant: securing land, establishing napier plantations and completing statutory approvals. We are actively talking to CBG offtakers, investors and engineering partners.
Build it with us
We are looking for landowners and farmers for napier cultivation, CBG offtakers, engineers and investors. One message reaches the people making the decisions.
