Abstract
The increasing global demand for sustainable energy has sparked interest in combining renewable technologies to leverage their synergies. This thesis presents a pre-feasibility study of a combined offshore wind and wave energy farm located off the coast of Galicia, Spain.
In collaboration with Wavepiston, a Danish developer of wave energy converters (WECs), the study evaluates the integration of their technology with a planned offshore wind power plant (WPP) in the same area. A structured methodology was applied, including site selection, WEC analysis and dimensioning, wave energy farm (WEF) output simulation, system design, and economic evaluation.
The results indicate that the integration of wave energy with offshore wind power can... (More)
The increasing global demand for sustainable energy has sparked interest in combining renewable technologies to leverage their synergies. This thesis presents a pre-feasibility study of a combined offshore wind and wave energy farm located off the coast of Galicia, Spain.
In collaboration with Wavepiston, a Danish developer of wave energy converters (WECs), the study evaluates the integration of their technology with a planned offshore wind power plant (WPP) in the same area. A structured methodology was applied, including site selection, WEC analysis and dimensioning, wave energy farm (WEF) output simulation, system design, and economic evaluation.
The results indicate that the integration of wave energy with offshore wind power can increase total power production and create a more stable and predictable generation profile. While standalone wind and wave systems experience periods of zero energy output, the combined system eliminates these entirely, though some low-output periods remain due to lower wavecapacity. Shared use of space and infrastructure enhances energy density and reduces the levelized cost of energy, particularly when WEC conversion equipment is housed within wind turbine towers.
Despite higher capital costs for wave energy, projected efficiency improvements suggest future cost reductions. Socially and environmentally, the project supports EU marine planning goals by offering low-impact, locally sourced renewable energy and job creation. Overall, co-located wind and wave energy farms appear technically feasible and economically promising, though further real-world testing and refinement are needed. (Less)
