Unveiling the Green Revolution: BAR Technologies' WindWings® Achieves Carbon Payback in Just Six Months
The Maritime Industry's Carbon Conundrum: A Game-Changer
The shipping industry has long grappled with its environmental footprint, and the quest for sustainable solutions is more urgent than ever. But here's where it gets controversial: traditional assumptions about the carbon cost of maritime innovation may be misleading. BAR Technologies, a pioneering company at the forefront of sustainable marine technology, is challenging these assumptions with its groundbreaking WindWings® system.
A Six-Month Carbon Payback: A New Benchmark
In a remarkable achievement, BAR Technologies has validated that its WindWings® system achieves a carbon payback in under six months. This is a significant breakthrough, as it demonstrates that the system not only reduces fuel consumption and CO2 emissions but does so in a remarkably short time frame. The study, conducted as part of the Impact Accelerator program, sets a new benchmark for transparency and lifecycle performance in the maritime sector.
Challenging Industry Assumptions
The WindWings® system, which already reduces fuel consumption by an average of 1.5 tonnes per wing per day, is offsetting its embedded carbon emissions in operational use in less than half a year. This challenges long-held industry assumptions about the carbon cost of maritime innovation. By quantifying the true environmental return on investment, BAR Technologies is providing shipowners, regulators, and investors with verified data to support rapid decarbonisation.
A Design Approach Focused on Sustainability
"This is a landmark moment for commercial wind propulsion," said John Cooper, CEO of BAR Technologies. "To demonstrate a sub-six-month carbon payback shows that WindWings® is not only delivering immediate environmental benefit but is a commercially ready solution that meets the industry’s urgent decarbonisation needs."
Will Hopes, Simulation and Performance Engineer at BAR Technologies, added, "Seeing the payback come out in months has validated our design approach. WindWings® are designed to decarbonise shipping as quickly as possible, and the study shows that this is what they are doing. LCA is a core part of every design review, not a separate consideration."
A Call to Action for the Maritime Sector
As decarbonisation becomes a defining challenge for commercial shipping, BAR Technologies urges the maritime sector to shift from assumption to evidence. The LCA results from WindWings® are proof that credible, verifiable sustainability is achievable today. We encourage other innovators and marine stakeholders to take part in the next MarineShift360 Impact Accelerator and drive change with the same transparency and urgency.
About BAR Technologies
BAR Technologies, with its impressive heritage from Great Britain’s former America’s Cup Team, provides a wide range of design and engineering consultancy services across commercial ships, workboats, leisure boats, and engineered solutions. The company boasts a team of world-leading naval architects, optimisation specialists, fluid dynamists, and system engineers, all focused on delivering next-generation maritime technology.
About WindWings®
BAR Technologies’ patented three-element wing design is unique in the marketplace, delivering 2.5 times the lift of a single-element wing. Unlike other wind-assisted propulsion systems, WindWings® require no continuous power for suction fans or mechanical spinning. They automatically adjust camber and angle of attack for optimised efficiency at the most angles and wind speeds, offering a proven, scalable solution for emissions reduction.
About MarineShift360
MarineShift360 is dedicated to driving meaningful change, providing the tools and resources required to significantly and permanently reduce the marine industry’s environmental impact. The project is centred around an innovative Life Cycle Analysis (LCA) tool that empowers the global marine industry to make data-driven sustainability decisions. Developed in partnership with 11th Hour Racing and Marine Futures, the tool provides comprehensive assessments across multiple environmental impact categories, helping organisations reduce their ecological footprint and transition to a circular economy.
