The Invisible Danger: how SF6-Free technology can help avoid 6.9 Million tons of CO2e in India

Reading Time: 3min

At Planet2050, we finance catalytic climate solutions that need a strategic bridge to scale. Beyond carbon removal, we also support Super Pollutants like SF6, which is 24,300 times more potent than CO2, and we’re proud to share our new paper with Berlin-based Nuventura on SF6-free switchgear in India.

Summary

  • SF6 is a highly potent greenhouse gas used in power grids, and it can remain in the atmosphere for over 3,000 years.

  • Nuventura’s Dry Air technology replaces SF6 with a zero-warming-potential alternative for switchgear.

  • Carbon finance can help scale the transition by creating carbon credits and future revenue streams.

  • The opportunity in India is large: the growing grid could lock in millions of tons of CO2e if SF6 is not replaced.

  • Planet2050 and Nuventura are showing that sustainable grid technology can also be financially viable.

SF6: The Silent Danger in the Power Grid

While most investors focus on CO2, there are other potent greenhouse gases which deserve attention such as fluorinated gases used in cooling or electrical infrastructure. In power grids, SF6 is commonly used as an insulator in "switchgear" (the circuit breakers that manage electricity flow). SF6 is technically very effective but environmentally devastating. Besides its high warming potential, it remains in our atmosphere for over 3,000 years.

The problem? The infrastructure is often leaky. Moreover, the gas is mishandled during operation or decommissioning. Especially critical: Mid- and low-voltage switchgear lack the valve to safely remove the gas. Hardware stored in landfills eventually rots, and the SF6 then escapes into the atmosphere.

The Solution: "Dry Air" Technology

The good news is that sustainable alternatives exist. Nuventura has pioneered Dry Air insulation for SF6-free switchgears. Made in Germany.

It provides the same high-performance protection for the grid but uses natural air, which has zero global warming potential. The solutions are especially fit for power grid distribution (36 kV switchgears). By replacing traditional SF6 systems with Dry Air alternatives, Indian utilities can eliminate a massive source of "fugitive emissions" and directly support India’s commitment to reduce emissions intensity by 45% by 2030.

How can Carbon Finance Accelerates the SF6 Turnaround


Transitioning electrical infrastructure requires significant capital. 

Our co-authored paper explores how Carbon Finance can bridge this gap:

  • Carbon Credits: by choosing SF6-free technology, utilities can generate verified carbon credits for avoided emissions.

  • New Revenue Streams: these credits can be traded in the future via India’s emerging Carbon Credit Trading Scheme (CCTS) or international markets under voluntary market or through the Paris Agreement carbon market (Article 6).

For carbon buyers and investors, this represents a "high-integrity" opportunity. Such a project isn’t about offsetting emissions; but preventing one of the world's most harmful industrial gases from growing even more into the atmosphere.

The Opportunity in India: Defusing an SF6 Bomb with 6.9 Million Tons of CO2e

India is expanding its power grid at an incredible rate to support its economic and electrification goals. This comes as of today with increased use of SF6, therefore a delayed-emission bomb with additional gases which may leak in 10 years or beyond.

Our joint research highlights the massive scale of this challenge:

  • Current Footprint: As of mid-2025, India’s medium-voltage (MV) switchgear contains approximately 160 tons of SF6,

  • The Forecast: As the grid grows to meet demand, this volume is expected to reach 286 tons by 2035.

  • The Impact: That is equivalent to roughly 6.9 million tons of CO2e carbon dioxide equivalent. This equals the annual emissions of 1.5 million passenger cars.

A Message from the Authors

This paper was a deeply collaborative effort between Amol Patharkar, Cassidy Kuiper, Probal Sarkar, and Planet2050’s Lucas Zaehringer. Published in Berlin on February 12, 2026, it serves as a roadmap for sustainable power infrastructure in India.

"By combining Nuventura’s sustainable hardware innovation with Planet2050’s carbon finance models, we can demonstrate that the sustainable choice can also be the most economically viable choice for the future of power grids, " so Lucas Zaehringer, CEO of Planet2050.
