MarineShift360 has disclosed the findings of its recent Impact Accelerator programme, highlighting the lifecycle assessment of BAR Technologies' innovative WindWings® system. The assessment illustrates that WindWings® achieves carbon payback in under six months, establishing a new standard for transparency and lifecycle efficiency in the maritime industry.
This milestone was reached following BAR Technologies' completion of the ten-month Impact Accelerator programme, which focuses on utilising advanced lifecycle assessment (LCA) to enhance sustainability in marine design and supply chains.
Embedded Carbon Emissions
The analysis confirms that the WindWings® system, which contributes to a reduction in fuel consumption of approximately 1.5 tonnes per wing each day, thereby reducing CO2 emissions by 4.7 tonnes daily on global shipping routes, offsets its embedded carbon emissions through operational use in less than six months.
This achievement contests traditional assumptions about carbon costs related to maritime innovations
This achievement contests traditional assumptions about carbon costs related to maritime innovations. By offering verified data, BAR Technologies supports shipowners, regulators, and investors in driving forward rapid decarbonisation efforts.
Commercially Ready Solution
"This is a landmark moment for commercial wind propulsion," stated John Cooper, CEO of BAR Technologies, adding "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."
Revising Composite Layups
According to Ollie Taylor, Director of Marine Futures, "These results show what is possible when organisations commit to fully understanding their impact. LCA gives leaders the data to make better decisions and the confidence to scale those decisions across fleets, supply chains and product lines. As a first year, these results are incredibly encouraging and show what the Impact Accelerator was created to do, which is to catalyse change across our industry."
The LCA, conducted in compliance with ISO 14044 standards, pinpointed metalwork as the largest contributor to embedded emissions (44%), prompting BAR Technologies to pivot procurement towards recycled-content DH32 steel via Electric Arc Furnace processes. Additional carbon reductions are realised by enhancing tooling utilisation and altering composite layups.
New Industry Standard
John Cooper further commented, "This wasn't just a validation exercise. It enhanced engineering reviews, procurement decisions, and customer conversations. We have embedded carbon literacy across every function because sustainable performance must be measurable, verifiable, and repeatable."
The results buttress BAR Technologies' design ethos, applying carbon payback alongside physical and financial performance as a pivotal design metric for all maritime innovations. By prioritising transparency, BAR Technologies is setting an industry precedent and urging others to adopt similar practices.
As the challenge of decarbonising commercial shipping grows, BAR Technologies calls upon the maritime sector to transition from assumption-based to evidence-based strategies. The LCA outcomes of WindWings® demonstrate that genuine, verified sustainability is feasible now and encourage other innovators and stakeholders in marine sectors to engage with the MarineShift360 Impact Accelerator, fostering change with equal transparency and urgency.
