Wave Devouring Propulsion: Harnessing the Power of Waves to Propel Ships

Cranfield University Researchers Develop Innovative Wave Energy Propulsion System

In a groundbreaking study published in the journal Renewable and Sustainable Energy Reviews, academics from Cranfield University have unveiled a new form of wave devouring propulsion (WDP) that could revolutionize the maritime industry. Inspired by the efficient movement of a whale’s tail fin, the researchers have developed a method to harness the power of waves for propulsion, offering a sustainable and cost-effective solution for ships. This innovative technology has the potential to significantly reduce greenhouse gas emissions and contribute to the industry’s carbon reduction targets.

1: Unraveling the Secrets of a Whale’s Fins

To understand the mechanics behind wave energy propulsion, the research team closely studied the structure and movement of a whale’s tail fin. Through a combination of simulations and experiments, they successfully integrated a simplified version of the whale’s tail fin action into a ship’s power system. By emulating the way whales effectively use wave energy for propulsion, the researchers have paved the way for a transformative approach to ship propulsion.

2: The Advantages of Wave Devouring Propulsion

Wave devouring propulsion (WDP) offers a multitude of benefits, making it an attractive solution for the maritime industry. One of its key advantages is the significant reduction in fuel costs. By harnessing the power of waves, ships can tap into a renewable energy source, reducing their reliance on fossil fuels and lowering operational expenses. Additionally, WDP technology enhances marine craft propulsion, allowing ships to achieve greater thrust and efficiency.

3: A Green Technology for a Sustainable Future

The integration of WDP technology into the maritime industry aligns with the sustainable development goals of the shipping sector. This innovative solution can be seamlessly incorporated into hybrid propulsion systems, including those powered by electricity, hydrogen, or fossil fuels. It also has potential applications in small, unmanned vessels, further expanding its versatility. By adopting WDP, the shipping industry can make significant strides towards meeting carbon reduction targets and contributing to a more sustainable future.

4: The Vision for Maritime Sustainability

Dr. Liang Yang, the lead researcher and a lecturer in marine renewable energy systems at Cranfield University, envisions WDP as a transformative force in maritime sustainability. He emphasizes that this technology goes beyond emissions reduction, aiming to align the shipping industry with sustainable development goals. With the boundless energy of waves at their disposal, ships can navigate towards a future where carbon reduction targets are met, and the industry embraces sustainable practices.


The innovative wave devouring propulsion (WDP) technology developed by researchers at Cranfield University holds immense promise for the maritime industry. Inspired by the efficient movement of a whale’s tail fin, this groundbreaking solution harnesses the power of waves to propel ships, significantly reducing fuel costs and enhancing marine craft propulsion. By integrating WDP into hybrid propulsion systems and small vessels, the industry can make substantial progress towards carbon reduction targets and contribute to a more sustainable future. With WDP at the helm, the maritime industry is poised to navigate towards a greener and more efficient era.
