The TIDES project will deliver one of the first tidal energy farms, located 2km off the Co. Antrim coast of Northern Ireland. Objectives include addressing technical problems associated with the environment, deployment, power generation and yield assessment. TIDES is led by DP Marine Energy, a Cork-based marine renewable energy development company. TIDES will lead to the deployment of a tidal energy demonstration array off Fair Head, Nothern Ireland. The aim is to calculate the total lifetime CO2 emissions of the tidal energy development. This is crucial for benchmarking tidal energy against other low-carbon electricity sourcs such as offshore wind.
