An innovative project could transform global shipping by using gigantic cylinders to propel cargo ships by the wind.
Today’s cargo ships, mostly powered by highly polluting diesel engines, are in line for a green revolution. A professor at the University of Miami is proposing a unique technology that could drastically reduce their greenhouse gas emissions.
The problem of diesel cargo ships
Diesel engines on cargo ships are responsible for massive air pollution. They emit significant quantities of greenhouse gases, contributing to global warming. Today, the International Maritime Organization is aiming for a net zero emissions reduction by 2050.
To achieve this goal, several solutions are being considered. Some are betting on high-tech sails, while others are exploring nuclear technologies. However, none of these options seems totally satisfactory.
Revolutionary technology: giant cylinders
Professor GeCheng Zha proposes an astonishing alternative. Instead of sails, he uses giant cylinders mounted vertically on ships. These cylinders can be lowered to fit under decks, offering unprecedented flexibility.
The technology used, called CoFlow Jet, draws air through the cylinders, compresses it and releases it to create thrust. According to simulations, this could reduce fuel consumption by 50%.
Using coflow jet technology
Initially developed for aircraft, CoFlow Jet technology is now being designed and simulated for ships. It is already being used by NASA for the exploration of Mars. This technology could make ships much more efficient than existing wind-powered propulsion systems.
By drawing air over the top of the wing, the technology compresses and releases it to propel the aircraft. Transposed to ships, this method could revolutionize maritime transport, reducing both costs and carbon footprint.
Reducing marine pollution
Use of advanced technologies
Flexibility in ports
This project is still in its infancy, but is already attracting a great deal of interest. The idea of replacing polluting diesel engines with giant wind-powered cylinders is an attractive one. Could tomorrow’s ships be more sustainable and environmentally friendly thanks to this innovative technology?
