The Electro-Mechanical Generator (EMG) is an innovative direct-drive system able to convert linear, reciprocating motion into electricity. It is based on the integration of a recirculating ballscrew and a permanent magnet generator.

In the EMERGE project, the EMG underwent testing in both relevant and operational environments to reach a Technology Readiness Level (TRL) of 7. In particular, it was bench tested with a Hardware-In-the-Loop (HWIL) configuration while submerged in synthetic salt water. Then, it was integrated with a point-pivoted Wave Energy Converter (WEC) and underwent sea trials in the Orkney Islands. This project allowed development of engineering solutions for survivability in the marine environment and gave valuable information concerning the EMG performance in real sea conditions.
