Hydrogen-enabled retrofits, IoT-powered carbon intelligence, and engineered decarbonisation for fleets, DG sets, marine engines and industrial equipment — without replacing existing engines.
This episode was originally recorded with @ABPNews and is shared here with their permission.In this in-depth podcast conversation, we discuss how hydrogen can function as an enhancer—not a replacement—for diesel, enabling meaningful emission reductions across real-world applications such as commercial trucks, generator sets, buses, and marine engines, without requiring changes to existing infrastructure.The discussion also touches on the journey of building climate-focused innovation at scale, and why sustainability does not need to come at the cost of performance or profitability. Clean energy solutions, when designed right, can be practical, measurable, and economically viable.
Explore StoryIndia’s green hydrogen drive could spark a new era of clean industrial power, but high delivery costs and patchy availability may derail the momentum. Could decentralised, point-of-use hydrogen be the real game-changer?
