YESEN Technologies Pvt Ltd, formed in 2019, is an engineering and technology company focused on developing, integrating and delivering sustainable products.
We support green technology initiatives and believe that innovation becomes meaningful only when it solves real human problems.
Our focus is on practical engineering solutions, especially in the marine sector, where cleaner alternatives are urgently needed.
2019
Year founded
YESEN Technologies Pvt Ltd was founded to develop, integrate, and deliver sustainable marine products. We support green technology initiatives with practical engineering solutions — from vessel design and fabrication to testing, launching, and commissioning.

To develop green technologies that make economic sense, so they can be used by people anywhere — from smart cities to the remotest parts of the earth.

To design, develop and patent greener products, intelligently adapting global technologies into solutions communities can maintain with local resources and local talent.

A more equal world where everyone has access to affordable, reliable and sustainable energy — reducing economic disparity while tackling climate change.
Every point below is something already built, certified, or in service.
Founded in 2019. Our solar-electric ferry entered regular passenger service on Vembanad Lake, Kerala in 2021 — the CIAL Vembanad project.
The B-KOOL pack is IRS-approved: Tier-1 LFP cells, integrated BMS, liquid cooling, and WiFi/Bluetooth monitoring.
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+ MNRE-registered solar installations across Kerala, plus completed commercial projects in Guam and Abu Dhabi.
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.
Every battery we ship is certified. Every vessel we fit is watched, live, from anywhere.
B-KOOL supports CAN & Modbus data protocols for integration with vessel management systems, with real-time WiFi and Bluetooth monitoring built in.
Live vessel data, battery status, motor performance, and system health, at your fingertips.
Track energy usage, predict maintenance needs, and optimize routes with actionable insights.
Web & mobile apps with data mining and predictive insights for proactive fleet management.
New electric boats and conversions of existing vessels — no sound, no vibration, no fumes.
Our E-Marine systems remove boating emissions and support sustainable boating to a new level — no sound, no vibration, no fumes, no breakdowns. We have delivered comprehensive e-boating systems in India and Australia.
Marine systems built for daily service — IRS-approved battery packs, intelligent monitoring and safety layers engineered for life on the water.

Electric vessels delivered with YESEN systems — tourism boats, ferries and houseboats running on our lithium packs — plus new solar-electric builds now under construction.
