What we do
Solutions and products built for a warming world
01 / 03
Products
In our fight against climate change we work with established energy technology manufacturers such as Phocos and V-Sun, trusted for high performance and reliable trouble-free operation. Alongside them we build our own indigenous range — T-Secure, P-Secure and H-Secure — for energy security, health security and waste management.

Why YESEN
Proven on the water,not just on paper.
Every point below is something already built, certified, or in service.
2019founded
In passenger service since 2021
Founded in 2019. Our solar-electric ferry entered regular passenger service on Vembanad Lake, Kerala in 2021 — the CIAL Vembanad project.
IRSapproved
Marine-certified battery systems
The B-KOOL pack is IRS-approved: Tier-1 LFP cells, integrated BMS, liquid cooling, and WiFi/Bluetooth monitoring.
10+vessel types
Retrofit or new build
E-MARINE kits electrify houseboats, shikaras, ferries, RORO and barges. We also deliver new-build vessels end to end — design, fabrication, testing, launch, commissioning.
200+installs
Work on land as well as water
200+ MNRE-registered solar installations across Kerala, plus completed commercial projects in Guam and Abu Dhabi.
3 yrpayback
The economics work out
No fuel, no emissions, and far fewer moving parts than an IC drivetrain — typically a three-year payback once fuel and maintenance savings are counted.
