Electric boats are water vessels that are powered by electric motors, rather than diesel engines, sail power or gasoline engines. They can be powered by on-board battery packs, solar panels or generators. Electric boats have been used for over 120 years, and were particularly popular from the 1880s to the 1920s. Since the 1970s, interest in electric boats has been increasing, as they are quiet and potentially renewable. Electric boats can be full battery electric, hydrogen fuel cell electric, or electric hybrid.

What You'll Learn
Electric boats are powered by electric motors
Electric boats can be full battery electric, hydrogen fuel cell electric, or electric hybrid. Electric hybrid systems pollute much less than traditional mechanical propulsion engines, as they blend power from both energy storage and generators, giving the vessel operator a dual power source. Electric propulsion systems don't pollute the air with carbon emissions and are too quiet to contribute to noise pollution.
In an electric boat, the energy is stored in the battery. This electrical energy is then transferred to mechanical energy, which powers the motor, drive train and propeller. The force of these moving parts against the water moves the boat. The amount of power required to move the boat depends on the speed and weight of the boat.

Electric boats are propelled by battery packs, solar panels or generators
Electric boats have been used for over 120 years, and were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily, especially as more efficient solar cells have become available.
The energy is stored in the boat's battery, and that electrical energy is transferred to mechanical energy. This powers the motor, drive train and propeller, which put force against the water to move the boat. Higher speed and/or bigger weight require more power transferred from electrical energy to mechanical energy.
Electric boats can be full battery electric, hydrogen fuel cell electric, or electric hybrid. Electric hybrid systems pollute much less than a traditional mechanical propulsion engine, as they blend power from both energy storage and generators to give the vessel operator a dual power source for greater vessel operational flexibility.

Electric boats are quieter than diesel-powered boats
The energy in an electric boat is stored in the battery, and this electrical energy is then transferred to mechanical energy in the motor, drive train and propeller, which put force against the water to move the boat. The speed and weight of the boat will determine how much power is transferred from electrical energy to mechanical energy.
Electric boats can also be powered by hydrogen fuel cells, which provide zero emissions performance and use hydrogen as a fuel to extend the operating range of the vessel.

Electric boats are more environmentally friendly than diesel-powered boats
Electric boats are more efficient than diesel-powered boats because they convert electrical energy into mechanical energy, which is then used to power the motor and drive train, and turn the propeller. This process is more efficient than burning diesel fuel, which produces a lot of waste heat.
Electric boats are also more flexible than diesel-powered boats because they can be powered by a variety of energy sources, including solar panels and other renewable sources. This means that operators can have greater independence by owning their power source.
Overall, electric boats are a more environmentally friendly option than diesel-powered boats because they produce fewer emissions, are more efficient, and are more flexible in terms of power sources.

Electric boats have been used for over 120 years
Electric boats can be full battery electric, hydrogen fuel cell electric, or electric hybrid boats or ships. Electric hybrid systems pollute much less than traditional mechanical propulsion engines, as they blend power from both energy storage and generators, giving the vessel operator a dual power source for greater vessel operational flexibility.
Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily, especially as more efficient solar cells have become available.

Frequently asked questions
An electric boat is a boat or ship whose primary propulsion technology is an electric drive system. It can be a full battery electric, hydrogen fuel cell electric, or electric hybrid boat or ship.
The energy is stored in a battery, which is then transferred to mechanical energy — the motor and drive train and propeller — which put force against the water to do the work of moving your boat.
Electric boats have been used for over 120 years. They were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant.
Electric boats don't pollute the air with carbon emissions and run too quietly to add to noise pollution. They can also be powered by solar panels and other renewable sources, which can provide greater independence by owning your power source.
