EquiMar involved about 60 scientists, developers, engineers and conservationists from 11 European countries working together to find ways to measure and compare the dozens of tidal and wave energy devices, proposed locations and management systems currently competing for funds, so governments can invest in the best ones and get marine energy on tap fast. The team has delivered a suite of “high level” protocols – general principles to allow fair comparison of marine energy converters testing and evaluation procedures. EquiMar protocols cover site selection, device engineering design, scaling up designs, deployment of arrays, environmental impact on flora, fauna & landforms, and economic issues. The final EquiMar protocols establish a sound base for future marine energy standards currently being developed by IEC Technical Committee 114.
