India's Energy Import Problem Has a Homegrown Answer: The Case for Biogas

Earlier this month I had the privilege of speaking at the World Biogas Association's eFestival, the global biogas sector's first major virtual gathering, brought forward by circumstance but no less significant for it. I was part of a session focused specifically on biogas potential in India, alongside Atma Ram Shukla, President of the Indian Biogas Association, and Gangagni Rao Anupoju, Senior Scientist at the Indian Institute of Chemical Technology. It was one of the more substantive conversations I have been part of this year, and I want to set out the thinking behind my contribution.

The starting point is a problem that tends to get lost in discussions about India's remarkable economic growth story: India is one of the world's largest importers of oil and gas. That dependency is a strategic vulnerability of significant proportions, expensive in foreign exchange terms, exposed to global price volatility, and increasingly at odds with India's own stated ambitions around energy security and climate commitments. Finding ways to generate fuel locally, at scale, is not an environmental aspiration for India. It is an economic and national security imperative.

The Swachh Bharat Mission as an Energy Framework

Most people are familiar with the Swachh Bharat Mission in the context of sanitation and waste management. What is less widely understood outside the sector is that the same mission creates the policy and infrastructure foundation for a substantial biogas industry.

The logic is straightforward. India generates enormous quantities of organic waste: agricultural residues, food waste, municipal solid waste, and animal manure at a scale that reflects a country of 1.4 billion people with a large rural economy. That waste is currently either left to decompose, releasing methane into the atmosphere as an uncontrolled greenhouse gas, or managed at significant cost to local authorities and communities. Anaerobic digestion captures that methane before it escapes, converts it to usable biogas, and in doing so transforms a waste management problem into an energy asset.

The Swachh Bharat Mission gives that opportunity a policy framework and, critically, a government mandate. The SATAT initiative, Sustainable Alternative Towards Affordable Transportation, has set a target of 5,000 compressed biogas plants across India, producing bio-CNG for transport and industrial use. That is an ambitious target, and delivery has been slower than hoped, but the direction of travel is clear and the underlying resource base to support it is genuinely vast.

What Clarke Energy Brings to This Conversation

Clarke Energy's interest in the Indian biogas market is not theoretical. We have been working in the Indian market long enough to understand both its enormous potential and the very real barriers to realising it, barriers that go beyond policy and financing to include feedstock quality and consistency, digestate management, grid interconnection in rural areas, and the challenge of delivering technically complex plants in locations where support infrastructure is limited.

The engine technology we work with, Jenbacher gas engines manufactured by INNIO, is well suited to the biogas application precisely because it is designed to handle the variability in gas quality that characterises real-world biogas production. That matters in India, where feedstock mixes are diverse and gas composition can fluctuate significantly between seasons and between plant types. An engine that performs reliably across that range is not a luxury specification. It is a prerequisite for commercially viable biogas-to-power projects. Clarke Energy also now offers complementary biogas upgrading systems. This technology cleans biogas, either for grid injection or for use as bioCNG in vehicle refueling stations.

What the session at the WBA eFestival reinforced for me is that the knowledge base within India, represented by organisations like the Indian Biogas Association and research institutions like IICT, is sophisticated and growing. The conversation between Indian technical expertise and international engineering and project development experience is the one that will actually move projects from feasibility to operation. Events like the WBA eFestival matter precisely because they create that space.

The Strategic Case, Simply Stated

India spends billions of dollars every year importing fossil fuels that could, in material part, be displaced by gas produced from organic waste that is currently a cost and an environmental liability. The technology to do that displacement exists, is proven at scale in Europe and elsewhere, and is increasingly competitive on project economics. The policy framework, while imperfect in implementation, is directionally correct. The feedstock resource is enormous and largely untapped.

The missing piece is not ambition. India has that in abundance. It is the acceleration of project delivery: more plants built, more engineers trained, more financing structures tested and refined, more operational data gathered to reduce risk for subsequent investors. That is a decade of work, not a year. But the direction is right, and the potential is as large as almost anywhere in the world.

That is the conversation I was glad to be part of at the WBA eFestival, and it is one I expect to be having for some time to come.
