BAR Technologies Advocates Wind Propulsion – A new report from the UCL Energy Institute has revealed an impending crisis for the maritime sector, warning that the accelerating energy transition could result in the premature scrapping of over a third of the global fleet, valued at more than $400 billion USD. Without substantial retrofitting, many vessels may be rendered obsolete due to increasingly stringent greenhouse gas (GHG) regulations and shifting fuel economics. However, wind propulsion is emerging as a viable solution, offering immediate emissions reductions and positioning vessels for long-term compliance.
A Crisis of Emissions and Obsolescence
The report highlights that both existing vessels and those currently on order are set to emit twice the permissible GHG emissions under a 1.5°C-aligned carbon budget. This poses a significant risk of supply-side asset stranding, where ships are forced out of operation before the end of their commercial lifespan. Additionally, there is a growing demand-supply imbalance, as operators scramble to align with carbon intensity indicator (CII) benchmarks.
Among the leading voices advocating for wind propulsion as a critical decarbonization tool is BAR Technologies, a pioneering firm specializing in aerodynamic solutions for shipping. The company emphasizes that wind-assisted propulsion can provide an immediate and cost-effective reduction in fuel consumption, mitigating risks associated with fuel market volatility and regulatory pressures.
Wind Propulsion: A Strategic Hedge Against Market Uncertainty
The maritime sector is facing an uphill battle as cleaner fuel options become more expensive and competitive, particularly against aviation and other industries vying for the same limited resources. This is particularly challenging for smaller operators, who lack the purchasing power of the largest shipping lines. According to Alphaliner data, out of the top 100 container lines, 76 operate fewer than 50 vessels, and 28 have fleets of 10 or fewer ships.
With the introduction of multi-fuel strategies, operators face uncertainty over long-term fuel availability and pricing. Wind-assisted propulsion eliminates this dependency by leveraging an abundant and freely available energy source. Unlike conventional fuels, wind is not subject to geopolitical instability, refining bottlenecks, or volatile pricing, making it an attractive alternative.
John Cooper, CEO of BAR Technologies, reinforced this point, stating:
“The shipping industry must now take wind propulsion seriously as a keystone resource and engage more deliberately to debunk concerns around operational complexity and reliability. The data is very clear: when averaged out over time, wind represents a steady, reliable, and highly abundant resource, which can be effectively ‘bunkered’ along many trade routes.”
Advancing Wind-Assisted Propulsion Systems (WASP)
BAR Technologies has been at the forefront of developing cutting-edge wind propulsion solutions designed for commercial viability and seamless integration into existing maritime operations. These include:
- WindWings® – A patented three-element wing design that delivers 2.5 times the lift of a single-element wing, automatically optimizing efficiency while consuming minimal power.
- AeroBridge® – An advanced aerodynamic superstructure designed to reduce fuel consumption and emissions by enhancing airflow around a ship’s hull.
- Hull Optimization – AI-driven hull designs for newbuild vessels, achieving double-digit fuel savings through enhanced hydrodynamic performance.
At last week’s RINA Conference, wind propulsion experts explored new techniques for maximizing wind bunkering yields, leveraging course and speed corrections to optimize performance. Mr. Cooper added:
“The digital technology exists to support officers and crew in applying effective wind-harvesting techniques. With decades of meteorological data, modern routing software, and our WindWings technology, we are confident that shipping can achieve a self-sourced fuel advantage that other industries simply cannot replicate.”
Conclusion: The Need for Immediate Action
With regulatory pressures mounting and fuel costs becoming increasingly unpredictable, wind propulsion is no longer an experimental concept—it is a necessity. The International Maritime Organization’s decarbonization targets will only become more stringent, and shipowners must look beyond traditional fuel alternatives to secure long-term competitiveness.
By embracing Wind-Assisted Propulsion Systems (WASP) and innovative aerodynamic solutions, the industry can future-proof its assets, avoid the looming $400 billion scrapping crisis, and take a significant step toward a zero-emission future.
