Could tidal energy take off in Ireland? Irish company, ÉireComposites, is leading a new €3.9m project to develop and market a marine hydrokinetic (MHK) turbine. The MHK turbine, which is placed below the water's surface, generates renewable electricity from tidal streams, ocean and river currents. It is estimated some 615 terawatt-hours per year could be produced using Ireland's as yet untapped tidal sources. To put that in context, that estimated energy creation is approximately 20 times Ireland's annual electricity consumption. Sustainable ÉireComposites has partnered with the Ocean Renewable Power Company and National University of Ireland Galway to commercially develop the turbine. The marine hydrokinetic turbines sit below the water's surface and generate electricity by harnessing tidal streams, ocean and river currents.
