BAR Technologies Promotes WindWings® for Emission Cuts

Following the International Maritime Organization’s (IMO) Marine Environment Protection Committee (MEPC) 83rd session, BAR Technologies is emphasizing the immediate benefits of Wind-Assisted Propulsion Systems (WAPS), particularly their WindWings® technology, for reducing maritime emissions.

The MEPC 83 session, held in London from April 7 to 11, 2025, focused on strategies to cut greenhouse gas (GHG) emissions from ships. Discussions included a new two-tiered GHG intensity reduction plan, which requires ships to progressively lower their well-to-wake GHG fuel intensity starting in 2028. Targets are set against 2008 levels, with reductions ranging from 4–17% in 2028 to 30–43% by 2035. The committee plans to review and potentially tighten these targets for 2036–2040 during its 2032 session.

Despite the session’s progress, it was marked by discord. The United States withdrew from negotiations, citing concerns over economic impacts and fairness. Meanwhile, a coalition of countries, including China and Brazil, proposed a credit trading system as an alternative to a flat carbon tax.

Amidst these discussions, BAR Technologies highlights wind propulsion as an immediate solution that doesn’t require lengthy deliberations or waiting until 2032. “Wind propulsion is a ‘no-brainer’ solution that significantly reduces emissions while offering economic returns,” said John Cooper, CEO of BAR Technologies. The maritime sector is already advancing, with wind technology installations doubling this year to over 100 ships. The potential for further adoption remains significant, offering immediate emissions reductions and economic benefits.

Additionally, starting May 1, 2025, the Mediterranean Sea will be recognized as an Emission Control Area (ECA) for sulphur oxides (SOx), requiring vessels to use fuel with a sulphur content not exceeding 0.10%. WAPS, including WindWings®, can help vessels meet these stringent requirements by reducing overall fuel consumption and emissions.

BAR Technologies’ WindWings® system features a patented three-element wing design that delivers 2.5 times more lift than traditional configurations. This advanced design provides greater thrust and adaptability, enabling consistent performance across global trade routes. By harnessing wind as a free, zero-emission energy source, WindWings® offers ship operators a practical pathway to reduce fossil fuel dependency and enhance operational resilience.

Each WindWing® can save approximately 1.5 tonnes of fuel and reduce CO2 emissions by 4.7 tonnes per day on average global shipping routes. The system’s scalability is demonstrated by the introduction of its 20m and 24m models, making WAPS accessible to a broader range of vessels, including handysize bulkers and chemical tankers, further expanding their impact on the industry’s carbon footprint.
