Today, global energy production is dominated by the use of fossil fuel such as coal, oil and natural gas but this type of energy production cannot be sustained. Marine energy offers potentially large resource with low environmental impact. The technology for marine energy conversion is now progressing through the prototype stage and research in this field has advanced these devices and systems into useful products, which are becoming economically viable for an increasing range of applications. The high load factors resulting from the fluid properties and the predictable resource characteristics make marine currents particularly attractive for power generation and advantageous when compared to other renewables.
Ifremer have launched a research program, based on PhD works [1 ; 2 ; 3], for the better knowledge of horizontal axis marine current turbines behaviour in harsh environments. The obtained results have been valorized through several scientific papers :
- some experimental developments for the evaluation of turbine performance and interaction effects :
- Tidal Energy Round Robin Tests. Comparisons between towing tank and circulating tank results, B. Gaurier, G. Germain & al., Int. J. of Marine Energy, Marinet special issue, Vol. 12, 2015
- Experimental study of the turbulence intensity effects on marine current turbines behaviour,
- specific studies to characterize the impact of turbulence and waves on the performance and loadings acting on tidal turbine :
