Keynote at iCANOE’25 at CUSAT

Marine transport has been central to global trade and human progress for centuries. Ships connect continents, enable commerce, and move 90% of the world’s goods. Yet, today the very systems that built global prosperity contribute significantly to environmental damage.

Climate change is no longer an abstract threat – it is measurable, accelerating, and deeply linked to human activity. Among the greenhouse gases, carbon dioxide (CO₂) remains the most significant driver of global warming. When we break down emissions by sector, marine transport contributes roughly 3% of global CO₂ emissions – a seemingly small percentage, but one that becomes enormous when measured in millions of tonnes and growing maritime trade.

So how do we change this trajectory?


The Sun: Our Primary Source of Energy

Every form of clean energy eventually traces back to the sun.

  • Solar panels convert sunlight into electricity.
  • Solar heat differentials create wind, which can be captured to generate power.
  • Heat also drives the water cycle, producing rain, rivers, and hydropower.
  • Electricity from renewables can be converted into clean fuels like hydrogen using electrolysis.

In theory, a relatively small area of solar panels – if efficiently deployed – could supply all the energy humanity requires.

But there is one unavoidable challenge:
The sun does not shine 24 hours a day.

This makes energy storage essential, not optional.


Transport Decarbonisation: Some Paths Easier Than Others

When we examine transportation sectors, electrification progresses differently:

  • Rail is the easiest – fixed routes, predictable loads, overhead power feasible.
  • Road transport is advancing quickly: batteries for cars, swappable packs or fuel cells for trucks, and even charging while driving is emerging.
  • Marine transport is more complex – energy requirements are high and charging offshore is difficult.
  • Aviation faces similar constraints, with weight and energy density being the core issues.

Marine decarbonisation demands a combination of technological innovation and economic viability.


Technology + Economics: A Turning Point

Two core technologies are driving the shift:

Solar Panels

Photovoltaic technology has existed for over a century, but large-scale manufacturing only took off in the last five decades. The breakthrough came in the past decade when adoption surged—and costs fell dramatically.

Lithium Batteries

Similarly, lithium-based storage has existed for decades, but only recently became affordable, scalable, and energy-dense enough for marine use.

These cost curves changed everything.


A Journey of Experiments, Failures, and Breakthroughs

Our story began in 2009 with SunRIder, an experimental solar boat. It earned a place in the Limca Book of Records as India’s fastest solar-powered vessel at the time.

In 2011, we experimented with retrofitting a fishing boat in Gujarat. The lesson was clear: electrification works—but retrofits don’t suit every application. Purpose-built electric vessels perform dramatically better.

Then, in 2014, came Aditya.

A solar-electric ferry built for Kerala’s State Water Transport Department, Aditya solved both technical challenges and economic ones: no diesel consumption, low operational expenditure, and reliable daily operations. Around nine years of data prove its success, transforming global perception of solar boats.


Scaling the Vision: More Boats, More Possibilities

From that breakthrough, the portfolio expanded:

  • Tourism boats like Avalon, Marsel, Destiny, Limo, Indra – even with air conditioning powered by solar.
  • Fishing boats with strong economics and social impact, including the Srav model developed with Shell Foundation.
  • Government-backed pilot projects such as IDEX electric boats for Navy, Tamil Nadu’s solar-wind hybrid fishing boat.

We are now building:

  • solar-electric RORO ferry – double-ended, catamaran hull, aluminium structure, delivering in 2026.
  • Defense patrol boats (FC series) with strong economic advantages.
  • High-speed foiling vessels that drastically reduce drag and energy use.
  • Autonomous surface vessels (ASVs) for research and monitoring.
  • Amphibious electric crafts.
  • Green tugs equipped with large thrusters and high-capacity batteries.
  • next-generation green ship with hydrogen fuel cells, wind turbines, megawatt-scale batteries, and high-efficiency propulsion – demonstrating future oceanic performance.

Where We Stand Today

What started as a single prototype is now a global movement.

  • 77 boats designed
  • A rapidly growing operational fleet
  • Multiple vessels under construction across applications

The momentum is real – and accelerating.


Our Mission: Cleaner and Quieter Oceans

The transition to sustainable marine transport is no longer a question of if – but when and how fast. By aligning technology, economics, and ecological responsibility, marine mobility can become not just cleaner, but better.

Our vision is simple yet ambitious:

Our vision is to to become the world’s foremost marine technology company, pioneering the electrification of marine transport.

Because the future of marine transport isn’t just electric –
it’s silent, sustainable, and regenerative.
