Led by Professor Christophe Gaudin and Dr. Hugh Wolgamot, with coordination by Dr. Wiebke Eberling from the University of Western Australia, the Albany M4 project aims to explore wave energy's potential to support local decarbonization efforts along Australia's Great Southern coast. The project's quarter-scale demonstration model is designed to absorb 1-10 kW in targeted sea conditions. The device is equipped with sensors that will provide real-time data on energy production and performance.
The M4 project is fully open-access, with all data collected during deployment made available to scientists, developers, and the public. By sharing this information, the project aims to encourage further innovation in renewable energy.
The M4, or Moored Multi-Mode Multibody, is a surface-riding wave energy converter that features multiple floats connected by beams, arranged in a 1-2-1 formation. The Albany tests use this configuration, where middle floats support hinges, and the wave-induced relative rotation between the bow and stern floats powers a generator. The M4's single mooring point enables it to naturally align with incoming waves, enhancing energy capture efficiency.
The M4 showcases Manchester's leadership in renewable energy innovation. Developed over the past decade with backing from the Engineering and Physical Sciences Research Council (EPSRC) and the European Union, the project also involved British Maritime Technology (BMT), responsible for the structural and mooring design. Dr. Judith Apsley from The University of Manchester's Department of Electrical and Electronic Engineering led the power take-off (PTO) design, further advanced with the help of Dr. Nuwantha Fernando at RMIT University in Melbourne.
Funded by 4.8 million AUD from the WA state government and the Blue Economy Cooperative Research Centre, with matching in-kind contributions, the project also highlights the broader impact of emerging renewable technologies. Six local contractors and manufacturers contributed to the device's construction, assembly, deployment, and decommissioning in Albany.
Professor Peter Stansby noted: "The M4 wave energy concept has been in development for over a decade, and these ocean trials represent a significant step towards full-scale Megawatt systems. This progress has been made possible thanks to the support of many colleagues at The University of Manchester, our partners, and importantly now the University of Western Australia."
The University of Manchester's Hydrodynamics Lab played a crucial role in the M4's development. This cutting-edge facility in Manchester allows researchers to simulate ocean conditions and test renewable energy technologies. Professor Stansby emphasized its significance, stating, "The Hydrodynamics Lab is vital for advancing renewable energy research. While computational modelling provides valuable predictions, experimental validation is essential for understanding and optimising complex systems."
