Driving Change
Engineering a Profitable Path to Net-Zero
Saarthi GreenTech was born from this question — not in a lab, but in the real world where diesel engines power logistics, manufacturing, shipping, mining, telecom infrastructure, and essential public services. The world cannot simply replace these engines overnight. Yet the climate cannot wait for long-term transitions.
We realised the world needed a solution that was practical, immediate, and scalable.
This is where our journey began.
Years of experimentation, failures, redesigns, and repeated field trials followed. We went from small engines to heavy trucks, from city buses to remote diesel generators, from testing grounds in India to validation trials across Asia.
Each setback sharpened the clarity of our vision. Each breakthrough confirmed that hydrogen-assisted combustion could become a powerful bridge to a cleaner world.
Our proprietary hydrogen retrofit systems eventually emerged from this long, disciplined pursuit — engineered to deliver both measurable decarbonisation and economic value. This dual benefit defines everything we build.
At Saarthi, we believe sustainability must be:
Practical, not aspirational
Affordable, not elite
Deployable today, not dependent on distant technologies
Scientifically validated, not promised
A catalyst for growth, not a burden on businesses
We exist to solve the world’s diesel problem at scale — by transforming engines already in operation.
Our hydrogen-enabled systems deliver immediate emission reduction and notable fuel savings, creating a path where profitability and sustainability reinforce each other.
Our name reflects who we are. In ancient tradition, a Saarthi is a guide, a navigator, the one who helps others travel farther with clarity and strength.
We stand at an inflection point. Hydrogen-enabled decarbonisation has moved from possibility to proof. The next chapter is scale — across fleets, factories, telecom networks, ports, marine engines, and beyond.
Global adoption of retrofit hydrogen technology
Integration of real-time IoT and ESG intelligence through GreenVision
Partnerships that accelerate emission reduction at enterprise and national levels
Innovation pipelines through GreenLabs to advance hydrogen-based solutions
To make sustainability profitable, scalable, and accessible by engineering hydrogen-enabled solutions that reduce emissions today and build a cleaner tomorrow.
Not merely to innovate, but to create impact.
Not just to build technology, but to shape an ecosystem.
Not just to decarbonise machines, but to empower people and industries to lead the transition.
The journey continues — with purpose, persistence, and an unwavering belief that the future must be built, not awaited.
