The world’s largest wind-powered cargo ship makes her maiden transatlantic voyage

BY THE OPTIMIST DAILY EDITORIAL TEAM

In a world where the shipping industry is wrestling with its environmental impact, a French startup called TOWT (TransOceanic Wind Transport) is presenting a solution that is both novel and rooted in centuries-old technology: wind. TOWT’s wind-powered cargo ship, Anemos, completed its first transatlantic voyage last month, delivering pallets of champagne, wine, and cognac from France to New York. For the first time in over a century, a major cargo vessel crossed the Atlantic virtually exclusively powered by wind.

“We know the wind is abundant, and we’ve known it for centuries,” says Guillaume Le Grand, TOWT’s cofounder and president. The organization can capture wind in methods that are both reliable and commercially viable due to recent advances in meteorological modeling, satellite communications, and routing technologies. Le Grand affirms: “The technology we have today makes wind a reliable source of propulsion.”

Not your average sailing ship

Humans have indeed powered their boats with wind for generations, however, Anemos is not your typical sailing ship. It is inspired by high-tech racing boats, with carbon fiber masts that are substantially lighter and taller than the wooden masts of traditional ships. This permits the sails to be twice as large and catch more wind, resulting in maximum propulsion. 

Anemos‘ most notable feature is its mechanical sail deployment system. Unlike conventional ships, which need teams of sailors to manage the rigging, Anemos can control all seven sails with a single remote. “You could actually handle the whole rigging—the seven sails on board, and 3,000 square meters of sail—with just one remote control,” Le Grand says. The ship is approximately 265 feet long, slightly larger than the famed Cutty Sark clipper ship, but with a considerably smaller crew—only seven sailors.

Anemos uses unique routing software to optimize wind power on its journeys. It has diesel-electric engines as a backup, yet it can sail completely on wind power for roughly 95 percent of the time. During her inaugural journey, the ship experienced significant delays and had to rely on fuel before departing France, but the final ten days of the voyage were totally powered by sails.

Furthermore, when the ship is traveling at a high enough speed, its propellers can spin in reverse, generating energy from the water’s wake to power onboard electronics. From the kitchen to the ventilation systems, the ship’s operations become more sustainable.

A climate-conscious shipping solution

While the capacity of Anemos—1,000 tons of cargo on pallets—is little in comparison to the 20,000-container capacity of current container ships, its function extends beyond sheer volume. Brands that use the ship’s service are motivated by more than just logistics; they see it as a method to achieve climate goals. According to Le Grand, buyers are willing to pay slightly higher transportation costs to reduce their carbon footprint. 

TOWT sweetens the bargain by providing long-term contracts with fixed prices, which eliminates the wild fluctuations associated with diesel and fuel oil costs. “We offer a predictable price without the swings of fossil fuels,” Le Grand informs me. Furthermore, the green marketing potential is enormous: manufacturers may attach a QR code to their products, which leads to data regarding CO2 savings on each voyage.

This transparency is an important selling factor in a market where consumers are becoming more concerned about their environmental impact. It is not enough to just ship items; it is also necessary to ship them sustainably.

Wind power versus greenwashing

As companies scramble to decarbonize, many are looking at other fuels, but Le Grand feels wind power is a better option. “The shipping industry, even though they seem to be willing to decarbonize, is sort of kicking the can down the road,” he points out. Many people are waiting for what he calls the “Santa” of decarbonized fuels, hoping that a low-cost, dependable alternative will arrive soon. However, Le Grand is wary of several proposed alternatives, including liquefied natural gas (LNG), which has the potential to cause severe pollution through methane leakage. 

Wind, on the other hand, is free, abundant, and ready for use right now. TOWT’s ships provide an immediate solution rather than waiting for technological improvements in alternative fuel sources.

Expanding the fleet and preparing the next generation of sailors

TOWT’s ambitious aspirations do not end with Anemos. The business has already built a second ship and plans to commence monthly transatlantic journeys. After carrying wine and spirits to the United States, the ships will travel to South America to return coffee to Europe. The company has also ordered six additional vessels, which will begin operating in 2026, with the long-term intention of deploying hundreds of wind-powered ships.

TOWT is not only expanding its fleet but also training a new generation of sailors. “We want to formalize and create a proper training for a modern sailing cargo captain, which doesn’t exist,” Le Grand explains. TOWT hopes that by teaching experienced sailors about this burgeoning business, it may create the groundwork for a larger shift in global shipping practices.

The winds of change are here

As the maritime industry faces increasing demand to decrease emissions, TOWT’s wind-powered vessels provide a realistic, modern alternative. With current technology making wind power more reliable than ever, and consumers keen to reduce their carbon footprints, the tide of change may be turning in favor of sustainable shipping.

TOWT’s concept of a fleet of wind-powered ships sailing the world’s oceans might represent a dramatic transition away from fossil fuel-based shipping. And, with firms willing to pay a premium for sustainability, it’s apparent that wind power isn’t a thing of the past—it’s the future of marine transportation.
