In response, BAR Technologies is calling for a broader discussion on shipping’s future energy mix, emphasizing the role of wind propulsion as a viable alternative.
The study underscores disparities in financing that could make e-fuels significantly more expensive in developing nations, despite their access to renewable energy sources like onshore wind and solar. With the International Maritime Organization (IMO) estimating that $1.6 trillion will be needed to achieve zero or near-zero emission fuels by 2050—including $400 billion by 2030—concerns are growing over the financial burden on less developed economies.
John Cooper, CEO of BAR Technologies, stated that while e-fuels are a promising solution, their high costs and financing barriers could slow down decarbonization efforts, particularly in emerging markets. He argues that wind-assisted propulsion systems, such as BAR Technologies’ WindWings®, offer an immediate and scalable solution without requiring extensive new infrastructure.
“Our industry must consider all available options rather than relying solely on costly e-fuels,” Cooper said. “Wind propulsion is an abundant and self-sufficient energy source that can help reduce fuel consumption and emissions without disadvantaging developing economies.”
BAR Technologies has developed WindWings® in three sizes—37.5m, 24m, and 20m—designed to support fuel savings and emissions reduction. The company states that its technology, inspired by aerospace engineering, enables vessels to reduce dependence on fossil fuels while improving operational efficiency.
As discussions continue ahead of the IMO’s MEPC 83 meeting in April, BAR Technologies is advocating for wind propulsion to be recognized as a key component of shipping’s decarbonization strategy. The company argues that incorporating wind into the energy mix will help ensure a fair and accessible transition for all stakeholders in the industry.
