In response to a new study by UMAS and the UCL Energy Institute’s Shipping and Oceans Research Group, which highlights the challenges faced by developing nations in accessing affordable financing for e-fuel production, BAR Technologies is calling for a broader, more inclusive debate on the future of shipping fuels.
While BAR welcomes the ongoing conversations around the development of alternative fuels such as e-ammonia, the company believes there is one fuel source that is consistently overlooked and must be seen as an integral part of the fuel mix: wind.
The report underscores the financial disparities that will drive the cost of e-fuels in developing nations significantly higher than in developed economies, even when they have superior renewable energy resources such as onshore wind and solar. As the shipping industry grapples with the cost of capital challenges in the global south, BAR Technologies insists that wind propulsion, a zero-emission, self-sufficient, and abundant energy source, should play a key role in helping to close the energy transition gap.
John Cooper, BAR Technologies CEO, said: “As the debate on new fuels heats up, it’s important not to overlook the most readily available energy source we have at our disposal: wind. While e-fuels hold promise, they come with significant costs and financing challenges that could hinder the global effort to decarbonise the shipping industry, especially in developing economies. Wind-assisted propulsion systems (WAPS) like WindWings will provide a scalable and commercially viable solution that not only helps meet decarbonisation targets but does so in a way that is accessible to all nations, regardless of their economic status.”
The study by UMAS and the UCL Energy Institute found that countries in the global south, despite having some of the best renewable resources, could face an additional financial barrier that would prevent them from competing with projects in developed economies. By 2030, the IMO’s strategy for achieving zero or near-zero emission fuels in shipping will require an estimated US$ 1.6trn in investment, with US$ 400bn needed by 2030 alone. If left unaddressed, the financial constraints identified in the study could exacerbate the existing inequalities in the shipping industry’s transition to greener fuels.
Cooper continued: “The solution isn’t to put all our eggs in one basket with costly e-fuels that will further disadvantage developing nations. Instead, we need to leverage the wind that’s already available and deploy technologies like WindWings, which deliver immediate fuel savings and emissions reductions without the need for complex and expensive new infrastructure. Wind-assisted propulsion offers a low-cost, scalable alternative that can be part of the broader mix, complementing the transition to cleaner fuels.”
The WindWings technology is considered to offer a proven solution for reducing fuel consumption and emissions, already helping ships worldwide achieve significant operational cost savings. BAR Technologies offers a range of WindWings models in three sizes: 37.5m, 24m, and 20m, designed to meet the diverse needs of the shipping industry. The systems employ a patented three-element rigid wing design inspired by aerospace engineering and optimised for modern wind-assisted propulsion. Harnessing the power of wind, this eco-friendly and reliable fuel source should help vessels reduce reliance on costly and volatile fossil fuels.
While the debate on new fuels and their financial implications continues, BAR Technologies remains committed to the wider adoption of wind-assisted propulsion as a critical component of the shipping industry’s decarbonisation strategy. With the IMO’s 2030 emissions targets fast approaching, the company is urging both the industry and participants at MEPC 83 in April 2025 to fully recognise wind’s potential as a key part of the solution. This is considered essential to ensuring that the transition to a zero-emission future is not only achievable but fair for all stakeholders. According to BAR, WAPS needs to be embraced as an integral element of shipping’s sustainable future.
Cooper concluded: “The winds of change are already here, and it’s time the shipping industry harnesses this abundant resource. We welcome all debate on the future of shipping fuels. Still, it’s crucial that wind propulsion is recognised as an essential, viable, affordable option to reduce emissions and cut fuel dependency to be able to achieve a just transition for all nations.”
