A Candela C-8 electric boat travelled from Sotogrande in Spain to Ceuta in North Africa in just over one hour last May. The 24-nautical mile journey consumed only 40 kWh of energy, cutting fuel use by 80% compared to conventional maritime ferries.
While electric cars now rule our streets, electric boats remain ghosts on our waters despite offering the same green promise.
Why Cars Went Electric But Boats Stayed Diesel
Walk down any European street today and you’ll spot Tesla after Tesla, BMW i4s humming past, Volkswagen ID.3s parked at charging points.
Electric cars have become part of daily life because governments pushed hard with subsidies and carmakers responded with better batteries and sleek designs.
Meanwhile, step onto any harbour and diesel engines still chug away like nothing has changed since the 1980s.
The gap feels odd when you consider that maritime transport could benefit even more from going electric. Boats don’t need to worry about finding charging stations in remote mountains or desert highways.
Short ferry routes, harbour shuttles, and coastal trips happen on predictable schedules between fixed points where charging stations make perfect sense.
When Water Fights Back Against Batteries
Of course, boats face problems that cars never encounter, and the biggest one sits right beneath the hull. Water pushes back constantly, demanding more energy than rolling wheels ever need.
Battery technology that works fine for a 300-mile car journey struggles when waves and currents drain power faster than engineers expected.
Range anxiety hits differently at sea too. Run out of juice on a motorway and you call roadside assistance or walk to the nearest petrol station. Run out of power mid-crossing and you’re calling the coastguard, assuming your radio still works.
Then there’s the charging puzzle that nobody talks about enough. Marinas lack the standardised high-power charging networks that now dot European motorways.
Each marina owner installs whatever system seems cheapest, creating a patchwork that confuses boat operators and slows adoption.
Old Salts Don’t Trust New Tech
Technical problems only tell half the story though. The maritime world operates on decades-old thinking that the car industry threw overboard years ago.
Shipping companies buy vessels expecting them to work for 20 or 30 years, so they stick with proven diesel engines rather than gamble on batteries that might not last half that time.
Maritime regulations move at the speed of bureaucracy too, unlike automotive standards that governments pushed through quickly to meet climate goals.
The International Maritime Organisation still debates basic guidelines for electric vessels while European car buyers can choose from dozens of electric models with standardised charging plugs.
Money talks loudest in the end. Governments that handed out generous subsidies for electric cars offer almost nothing for electric boats, despite their potential to clean up coastal air quality.
Marine diesel stays cheap and available everywhere, removing the economic pressure that drove motorists toward electric alternatives.
Mediterranean Geography Offers Europe Advantages
Here’s where geography hands Europe a winning card that America and Asia can’t match.
The Mediterranean works like a giant lake with short crossings perfect for electric propulsion. Compare that to the vast Pacific routes that American and Chinese shipping companies navigate, where electric power makes little sense for now.
European ferry routes between Spain and Morocco, Italy and its islands, Greece and Türkeye already carry millions of passengers annually on journeys well within electric boat range.
Rather than wait for distant competitors to solve electric maritime transport, Europe could test and perfect the technology in its own backyard.
European ports have another advantage worth noting. Many already invest heavily in wind and solar power, creating the clean electricity that makes electric transport truly green.
Port authorities in Barcelona, Marseille, and Naples could work together to build charging networks that serve the whole Mediterranean basin.
A Roadmap: Learning From Car Industry Success
The automotive industry’s electric revolution offers a roadmap for marine transport that Europe could follow. Partnerships between established car manufacturers and innovative boat builders, like the collaboration between
Candela and Polestar, show how automotive expertise can accelerate marine development.
European battery technology, refined through years of car manufacturing, could power the next generation of ferries and coastal vessels. The charging infrastructure that now supports millions of European electric cars provides templates for marine installations.
Government policies that made electric cars attractive could work equally well for boats. Tax breaks, purchase subsidies, and emission zone restrictions helped shift car buyers toward electric vehicles. Similar incentives could persuade ferry operators and leisure boat owners to try electric propulsion.
North African Partners Stand Ready
Mediterranean cooperation extends naturally to North African shores, where countries like Algeria, Tunisia, and Morocco would welcome cleaner ferry connections to European markets. The Maghreb faces growing air quality concerns in coastal cities where diesel ferries contribute to pollution problems.
Electric ferry services could strengthen economic ties while reducing environmental damage. Tourism between European and North African destinations would benefit from quieter, cleaner transport that preserves coastal environments for future visitors.
The Swedish crossing proved that electric boats can handle Mediterranean distances reliably. Regular services between Barcelona and Tangier, Sicily and Tunisia, or Cyprus and Turkish ports would demonstrate commercial viability on routes that matter to millions of travellers.
Rather than waiting for American tech giants or Chinese manufacturers to dominate electric maritime transport, Europe could leverage its Mediterranean geography to become the global testbed for zero-emission ferries.
The infrastructure exists, the distances work, and the environmental benefits are clear.
European shipyards could build the vessels, European ports could install the charging networks, and passengers could enjoy the first taste of truly sustainable sea travel.
