Beyond Fossil Fuels: Can an Indian deep-tech startup completely eliminate fossil fuels from global manufacturing?

In this episode, we sit down with Ashish Sethi, one of the three co-founders and CEO of Trigen Decarbonisation, an IIT Madras-incubated company that is rewriting the rules of clean tech and industrial decarbonization.

Industrial heat generation may sound like a boring topic, but it affects each of us because it accounts for a staggering amount of global carbon emissions. While the world has focused heavily on greening the grid with solar and wind, the massive, fossil fuel-guzzling boilers inside factories have remained notoriously difficult to clean up.

Enter Trigen DC. By engineering indigenously built, high-temperature heat pumps capable of breaking engineering barriers, this "Made in India" startup is proving that the future of heavy industry can be entirely electrified, zero-combustion, and highly profitable.

What We Discuss in This Episode: From the Peaks of Ladakh to the Factories of Odisha: Discover the unbelievable versatility of Trigen's tech. Their ultra-low ambient heat pumps are deployed to provide crucial space heating for defence troops in extreme sub-zero conditions (-30°C and below) in regions like Ladakh, while simultaneously delivering localised cooling to dramatically improve working conditions for factory workers facing gruelling heatwaves in places like Odisha.

A Rarity on the Global Stage: Achieving commercial steam and pressurised hot water up to 120°C–145°C via electrical heat pumps is a milestone only a handful of technical organisations worldwide have ever mastered. Ashish explains how Trigen became a global outlier in the deep-tech space.

The Gulf War Catalyst: Why global geopolitical shifts and energy volatility tax are forcing massive industrial clients to drastically advance their timelines for installing clean thermal infrastructure.

The Multi-Million Dollar ROI: How replacing legacy diesel and gas boilers with intelligent, closed-loop heat pump systems cuts energy bills by up to 50%, or even more, saving manufacturers millions while hitting aggressive net-zero and ESG targets. Whether you are passionate about climate action, sustainable manufacturing, or the rise of Indian deep-tech innovations, this conversation offers an evidence-based masterclass in how hardware engineering can solve our biggest environmental challenges.
