Affordable, reliable, sustainable
Energy access as an equaliser
Climate action with real economics

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.

The Technology

Engineered cell to cloud — not just charged and shipped.

Every battery we ship is certified. Every vessel we fit is watched, live, from anywhere.

B-KOOL Battery Technology

Certified from the cell up

B-KOOL supports CAN & Modbus data protocols for integration with vessel management systems, with real-time WiFi and Bluetooth monitoring built in.

IRS Approved LFP Marine BatteryCertified marine-safe, not just marketed that way

Certified Safe
