Innovative Method for Affordable Generation IN ocean Energy

Project description

Wave-breaking technology to harness marine energy

In theory, wave energy is more reliable and powerful than other renewables, but it is the least developed. Challenges in device design, durability and placement have inhibited development, not to mention environmental concerns for marine life. The EU-funded IMAGINE project aims to design, fabricate and demonstrate a prototype electromechanical generator (EMG) for wave energy applications that is able to convert slow speed, reciprocating linear motion into electricity. The EMG’s architecture will significantly enhance efficiency (70-85 %), reliability (20 years mean time between failures) and affordability (50 % reduction in capital expenditure). Following testing on a hardware-in-the-loop bench, technological risks will be reduced and a business plan will be developed.

Objective

The IMAGINE “Innovative Method for Affordable Generation IN ocean Energy” project aims at developing the Electro-Mechanical Generator (EMG), an innovative Power-Take Off (PTO) concept for wave energy applications able to convert slow speed, reciprocating linear motion into electricity. The EMG is based on the integration of a recirculating ballscrew and a permanent magnet generator, an architecture that dramatically improves average efficiency (70-85% also when working outside design conditions), reliability (20 years MTBF) and affordability (CAPEX reduction by over 50%) compared to state-of-the-art PTOs. During the IMAGINE project, the EMG technology will be demonstrated through the fabrication of a 250 kW prototype and its testing on a HardWare-In-the-Loop (HWIL) bench. This will allow progressing its TRL from 3 to 5. A range of Wave Energy Converters (WECs) will be emulated on the HWIL bench and the performance of the EMG, under the action of a robust control system, will be measured and extensively assessed. Furthermore, a FMECA analysis and a subsequent accelerated life test will prove the reliability of the system. HWIL tests will allow reducing technological risk in power rating increase, providing an intermediate step between tank tests and sea trials that represents a critical transition for wave energy development. Finally, a techno-economical assessment of the EMG and a complete Business Plan for commercialization will be developed. Such activities will be carried out by an international consortium with multi-disciplinary skills in marine energy, led by a leading-manufacturing company as Umbra Cuscinetti S.p.A.
The IMAGINE project is related to the topic “Developing the next generation technologies of renewable electricity and heating/cooling”, under the category “Ocean Energy: Development of advanced ocean energy subsystems: innovative power take-off systems and control strategies.
