In 2025, India’s maritime sector is witnessing an unprecedented transformation as solar-powered fishing boats begin to replace traditional diesel vessels. These innovations are reshaping the fishing industry, empowering thousands of coastal families, and helping India meet its commitment to sustainable development and carbon neutrality.
The shift from fossil fuels to clean energy isn’t merely a technological upgrade—it’s a lifeline. With over 16 million livelihoods dependent on fisheries, the integration of solar-electric propulsion systems is enhancing efficiency, cutting costs, and reducing pollution across India’s coastlines.
Introduction
Fishing has long been the backbone of India’s coastal economy. From Kerala’s backwaters to Gujarat’s harbors, small fishing boats form the pulse of India’s marine livelihoods. Yet, the sector has struggled under the weight of environmental degradation, rising fuel prices, and diminishing fish stocks. Diesel-powered boats contribute significantly to marine pollution, carbon emissions, and operating costs.
Solar fishing boats—equipped with photovoltaic panels, lithium batteries, and electric propulsion systems—bring new hope. These vessels offer zero-emission operation, silent movement, and drastic cost savings. Coupled with support from the Department of Fisheries, ICAR-CIFT, and Odisha Renewable Energy Development Agency (OREDA), India’s fisheries are embarking on an eco-revolution at sea.

What Are Solar-Powered Fishing Boats?
Solar-powered fishing boats harness solar photovoltaic (PV) energy to drive electric motors, either fully replacing or supplementing conventional diesel engines. Solar panels are installed on the deck or roof of the boat, continuously charging onboard batteries during daylight.
Key Components:
- Solar Panels: Convert sunlight into electricity.
- Battery Packs (Lithium-ion): Store energy to power motors during cloudy weather or night operations.
- Electric Motors: Provide propulsion without emissions or noise.
- Hybrid Engines (Optional): Diesel engines for extended range or heavy-duty backup.
- Energy Management System (EMS): Distributes stored energy efficiently for propulsion and onboard equipment.
These boats are classified into two types:
- Fully Solar-Electric Boats: Operate exclusively on stored solar power.
- Hybrid Solar Boats: Use a mix of solar and diesel energy for reliability on longer routes.
ICAR’s Breakthrough: “Vikalpika” – India’s First Electric Fishing Vessel
In May 2025, the ICAR-Central Institute of Fisheries Technology (CIFT) launched “Vikalpika”, India’s first hybrid electric fishing boat, marking a monumental shift toward sustainable marine operations.
Key Features:
- Length: 7.92 meters (26 feet)
- Solar System: 1.65 kW solar array
- Battery Capacity: 23 kWh lithium pack
- Hybrid Engine: 20 HP diesel (for backup only)
- Range: Up to 10 km offshore
- Endurance: 8–10 hours on a full charge
- Fuel Savings: Up to 70% compared to conventional boats
- Cost of Conversion: ₹15 lakh per vessel
- ROI Period: ~3 years
Developed under the Alternate Fuel and Energy Systems (AFES) Project, Vikalpika’s success story is driving replication efforts in Kerala, Maharashtra, Odisha, and Andhra Pradesh. It’s a clear demonstration of how innovation meets sustainability in India’s blue economy.
Why Solar Fishing Boats Matter for India
1. Economic Relief for Coastal Communities
Fuel costs account for nearly 70% of a fisherman’s operational expenses. Solar boats eliminate fuel dependency and reduce annual spending by up to ₹75,000–₹1 lakh per vessel. As a result, fishermen earn more without increasing effort or environmental impact.
2. Environmental Sustainability
Conventional boats emit harmful pollutants into fragile marine ecosystems. By replacing diesel with solar power, India’s coastal states are reducing CO₂ emissions and improving air and water quality.
3. Quieter Operations
Solar-electric motors allow near-silent propulsion, minimizing underwater noise pollution that scares fish and disrupts aquatic habitats.
4. Empowering Small Fishermen
Low operational costs enable small-scale fishermen to extend trips, add refrigeration systems, and ensure fresher catches, boosting market incomes.
5. Aligning with India’s Climate Goals
Transitioning to solar fishing supports India’s Nationally Determined Contributions (NDCs) and Net Zero 2070 roadmaps, promoting green jobs and local manufacturing.
Case Study: OREDA’s Solar Fishing Initiative – Odisha 2025
Odisha, with its 480 km coastline, is pioneering solar and electric boat deployment through the Odisha Renewable Energy Development Agency (OREDA).
Highlights:
- Investment: ₹20 crore allocated for phase-wise implementation.
- 100 fishing boats to be retrofitted with solar-battery power systems.
- Five solar-powered tourist and fishing boats already operational at Chilika Lake, demonstrating zero-emission navigation.
- Annual operational savings range from 60–70% compared to fuel-powered alternatives.
These clean boats ensure the protection of the Irrawaddy dolphin habitat while offering economic stability to Chilika’s 150,000 fishing families.
The Role of Private Innovators: Navalt, Mazagon Dock, and Others
Private Indian firms such as Navalt Solar & Electric Boats, Mazagon Dock Shipbuilders (MDL), and Innovegic India are scaling India’s clean marine technology ecosystem.
