Bengaluru-based Pranos Fusion: India’s Answer to Fusion Energy

Inside Pranos Fusion: The Indian Startup Taking on Fusion Energy

Nuclear fusion has long promised an extraordinary energy source: electricity generated by combining atomic nuclei, using the same fundamental process that powers the Sun. Unlike conventional nuclear fission, which splits heavy atoms, fusion aims to release energy by joining lighter nuclei under extreme temperatures and pressures. Reproducing those conditions in a controlled machine, however, remains one of the most difficult engineering challenges in science.

Founded in 2024 by Dr. Shaurya Kaushal and Roshan George, Bengaluru-based Pranos Fusion is attempting to tackle that challenge as a private Indian deep-tech company. Rather than concentrating on a single experimental device, it is building an integrated technology platform spanning reactor hardware, specialised magnets, and software for designing and controlling fusion machines. The company is incubated at the Jawaharlal Nehru Centre for Advanced Scientific Research and the Institute for Plasma Research, with connections to India’s wider plasma-physics research ecosystem and the international fusion community.

Its approach reflects a shift from studying fusion physics alone toward developing the engineering systems required to turn experimental machines into repeatable, scalable technology. Pranos is still at an early stage, but its ambition is to contribute to the infrastructure that could eventually make fusion-generated electricity commercially practical.

Building the Sun on Earth: The Technology Behind Pranos Fusion

Pranos organises its technology around three connected components: PRAGYA, JENGA, and MAGGA.

• PRAGYA is its compact, small-aspect-ratio tokamak, a type of fusion device that uses powerful magnetic fields to confine extremely hot plasma. Keeping this plasma stable and controlled is essential because it must reach the conditions required for fusion without damaging the surrounding machine.
• JENGA is the company’s machine-design and plasma-control software, intended to connect physics simulations, engineering design, and operational control. This digital layer can help researchers test configurations, model machine behaviour, and shorten the cycle between simulation and physical experimentation.
• MAGGA focuses on high-temperature superconducting magnets, which are critical to generating the intense magnetic fields needed for compact magnetic-confinement systems.

By developing these components together, Pranos aims to coordinate reactor geometry, magnetic-field design, and control systems instead of treating them as independent engineering problems. The company announced that the first plasma in PRAGYA was a target for 2026, an important milestone in moving from design and construction toward experimental operation.

Achieving first plasma would demonstrate that the machine can generate and confine plasma, but it would not by itself prove net energy production or commercial viability. Those goals require progressively more demanding evidence involving plasma performance, operating duration, system reliability, and the overall energy balance.

Can Pranos Fusion Help Power India’s Energy Future?

In March 2026, Pranos Fusion raised $6.8 million, approximately ₹63 crore, in a funding round co-led by pi Ventures and Ankur Capital, with participation from existing investor Industrial47 and other backers. The investors included Groww co-founder Lalit Keshre, the founders of Razorpay through Mars Shot Ventures, and Bhukhanwala Industries.

The funding is intended to advance the company’s fusion technology, expand testing infrastructure, and grow its engineering team. The investment is notable because commercial fusion requires sustained funding across several disciplines long before a company can sell electricity.

For India, a domestic fusion venture could eventually help build expertise in superconducting magnets, plasma-control systems, advanced manufacturing, and reactor engineering, even while commercial power remains distant. Rising electricity demand from industrial expansion, electrification, and energy-intensive computing makes reliable low-carbon power an important long-term objective.

Fusion could potentially contribute to that future because its fuel cycle offers the prospect of abundant energy with no carbon emissions from the fusion reaction itself, although practical fuel supply, waste from activated materials, operating costs, and engineering constraints remain significant challenges. Pranos must still demonstrate that its integrated technology can work reliably under demanding experimental conditions and progress toward a viable energy balance.

Its $6.8 million round provides resources to pursue those milestones, not proof that the commercial problem has been solved. If the company can translate its software, magnets, and compact tokamak designs into validated experimental performance, it could become an important contributor to India’s emerging fusion-energy ecosystem.
