German startup CargoKite has developed what it calls the “sailing ship of the 21st century” which uses a large kite to pull the vessel along, thereby providing sustainable, clean power. 

Why? 

The new wind-powered micro-ships, developed by CargoKite and Lomar’s corporate venture lab have been designed to tackle a variety of challenges for today’s shipping, including: 

– Ships run on heavy fuel oil (the dirtiest fuel in the world), making global shipping responsible for nearly 1 Gigatonne of CO2 emissions per year (more than all of Germany combined). Although freight ship owners and operators worldwide are working towards improved efficiencies and cleaner fuels, these actions are unlikely to be enough to meet targets for emissions reduction set by the International Maritime Organisation (IMO). This means that heavy fuel oil-powered freight ships in their current form are not sustainable and are contributing to the climate crisis. 

– Ultra-Large Vessels stacked high with containers may be cost-efficient, but only 5 per cent of ports have sufficient infrastructure to accommodate them. On all other routes, small, less cost-efficient ships are in use, which can double transport costs.  

– Just one incident such as a (large) ship getting stuck in the Suez Canal or a labour strike in a port shutting down major parts of global shipping leads to massive congestion and can cost £billions in just a few days.  

– Having to serve thousands of customers with a single ship makes individualised routing and just-in-time delivery very difficult for shipping companies, forcing cargo owners to keep expensive inventory. 

– 98 per cent of ports are not directly connected and time intensive stop-offs and transshipments can slow things down and add unnecessary transportation time. 

Are CargoKite Micro Ships The Answer? 

CargoKite believes the answer to these challenges is to develop the new ship class of ‘micro ships’ using large kite systems as the main method of propulsion and cutting-edge AI for autonomous operation.  

The Kite 

The main propulsion system for the new CargoKite ships is an advanced kite that flies at altitudes between 100 and 300 metres. These are heights where the wind is stronger and more consistent, enabling the kite to effectively pull the ship using wind energy alone. 

How The New Ship Design Meets The Other Challenges 

The design of the new CargoKite ship is able to meet the challenges of today’s freight vessels in the following ways: 

– Reducing heavy fuel oil dependency. Having a wind-powered kite as the main propulsion method eliminates the need for heavy fuel oil. By relying on renewable wind energy instead, the new CargoKite ship is 100 per cent emission-free and is a sustainable alternative that aligns with global emissions reduction targets set by the International Maritime Organisation (IMO). 

– Accessing a broader range of ports (micro ships are smaller). Unlike ultra-large vessels that require substantial port infrastructure, CargoKite’s micro ships are designed to be small (carrying only 16 containers each) and autonomous, enabling them to access a broader range of ports, including those with limited facilities. This decentralised approach allows for more flexible and cost-effective shipping routes, reducing dependency on the 5 per cent of ports capable of handling larger vessels, thus lowering overall transport costs. 

– Minimising congestion and disruption risks. CargoKite’s fleet of smaller, autonomous ships reduces the risk of massive congestion caused by incidents like the Suez Canal blockage. These micro ships can operate independently and flexibly, providing more resilience to the global shipping network. By avoiding the bottlenecks associated with larger vessels and major ports, they ensure more reliable and uninterrupted cargo transport, even in the face of disruptions. They also offer 1.5x higher operation speed, no unnecessary stops (direct transport), and no transshipment, thereby enabling up to 40 per cent time savings compared to today’s transport times. 

– Enabling individualised routing and Just-in-Time (JIT) delivery. The small, autonomous nature of CargoKite ships allows for more tailored and on-demand shipping services / an individualised  taxi-like service for cargo to replace today’s fixed schedules. This means they can travel any route, on-demand, and are fully traceable and just-in-time for cargo owners of every size, from startup to corporate, thereby reducing the need for cargo owners to maintain expensive inventories. This flexibility supports modern supply chain demands and enhances operational efficiency. 

– Enhancing direct connectivity between ports. CargoKite’s ships are designed for direct point-to-point transport, which minimises the need for time-intensive stop-offs and transshipments. This improves overall efficiency by reducing unnecessary delays, thus shortening transportation times. 

CargoKite says that shifting the paradigm from large inflexible freight ships to small autonomous, kite-powered micro ships is the cheapest way to fully decarbonise commercial freight shipping. 

Reframing Port and Maritime Logistics 

Stylianos Papageorgiou, Managing Director of Lomar labs, the company partnering CargoKite to produce the micro ships says: “This radical new ship type has the potential to reframe the way port and maritime logistics are organised. It brings a paradigm shift to operations, which is only now becoming possible thanks to advances made in automation technologies. In addition, it promises to be a groundbreaking decarbonisation solution for shipping.” 

Marcus Bischoff, Co-Founder & CTO of CargoKite says: “This collaboration aims to develop sea transport that is not only 100 per cent emission-free, but also supports the goals of modern supply chains: customisation, just-in-time delivery, full transparency and cost savings”. 

What Does This Mean For Your Business? 

The introduction of CargoKite’s kite-powered micro ships could deliver an important shift for businesses reliant on maritime logistics. By leveraging sustainable wind energy, these innovative vessels provide a 100 per cent emission-free alternative to traditional heavy fuel oil-powered ships, aligning with global environmental targets and significantly reducing the carbon footprint of shipping operations. For businesses, this not only means compliance with stricter environmental regulations but also an opportunity to enhance their green credentials, appealing to an increasingly eco-conscious market. 

CargoKite’s micro ships also appear to offer practical solutions to several longstanding logistical challenges. For example, their smaller size and autonomy enable access to a wider range of ports, including those with limited infrastructure, which traditionally could not accommodate ultra-large vessels. This expanded accessibility could lower transportation costs and provide more flexible routing options, ensuring that goods reach their destinations more efficiently and with fewer delays. 

Also, the resilience and flexibility of a fleet of smaller, autonomous ships could mitigate the risks associated with major disruptions in the shipping industry, such as the disruption, congestion and economic losses caused by the Suez Canal blockage or port strikes. These sorts of issues are less likely to impact a network of decentralised, agile vessels, thereby enhancing the reliability of supply chains, ensuring smoother operations even in the face of unexpected challenges. 

CargoKite’s model also appears to support modern supply chain demands through its ability to provide individualised routing and just-in-time delivery services. This adaptability could reduce the need for maintaining large, expensive inventories and allow businesses to respond swiftly to market changes. The direct point-to-point transport capability could further reduce unnecessary delays, ensuring faster and more predictable delivery times. 

Integrating CargoKite’s sustainable, flexible, and efficient shipping solutions, therefore, could revolutionise how businesses manage their maritime logistics. By adopting these innovative micro ships, companies may be able to achieve significant cost savings, enhance operational efficiency, and demonstrate a strong commitment to sustainability.
