Greenwashing? Cargill Tests Wind-Powered Cargo Vessel

The world’s largest agricultural trader, Cargill Inc., has retrofitted one of its bulk carriers with two massive steel sails. The sails, called WindWings, are designed to reduce the ship’s fuel use by roughly a fifth.

The ship, the Pyxis Ocean, is an 80,000-ton vessel that just completed her maiden voyage between Shanghai and Singapore. The installation of the WindWings, each 37.5 meters (123 feet) high, took place at a Cosco shipyard in Shanghai. 

Designed by BAR Technologies and produced by Yara Marine Technologies, they say the WindWings can save the ship about 1.5 tons of oil-derived fuel per day. And with these sails, the Pyxis Ocean can save about 1,095 tons of fuel a year, almost 20% of what a Kamsarmax ship typically annually consumes.

The shipping industry is a major polluter, emitting about 3% of global greenhouse gas emissions. The International Maritime Organization, the industry’s global regulator, has set a goal of reducing emissions by 50% by 2050.

Wind-assisted propulsion is one of a number of technologies that the shipping industry is exploring to reduce emissions. Other technologies include using alternative fuels, such as biofuels and hydrogen, and improving the efficiency of ships’ engines.

The installation of the WindWings on the Pyxis Ocean is a significant step forward for the use of wind power in shipping. It is the first time that a large commercial vessel has been retrofitted with this technology.

If the trial on the Pyxis Ocean is successful, it could pave the way for the wider adoption of wind-assisted propulsion in the shipping industry.

Critics on social media have accused the country’s largest private company of greenwashing, pointing out that the math may not all make sense, considering the weight of the massive sails.

Some have also questioned the high cost of installing and maintaining the sails.

But Cargill is looking farther ahead. It is hoping to add sails to as many as 10 more vessels in the future. 

“It’s going to make the new fuels a lot more affordable,” Jan Dieleman, president of Cargill’s ocean transportation business told Bloomberg. “Wind is there for free.”
