EU-funded researchers have developed new tools for designing and analysing the economic reliability and environmental performance of wave and tidal-energy power farms. These are currently being implemented and validated in real-life situations, while the DTOCEAN consortium has secured further EU funding.EU-funded researchers have developed new tools for designing and analysing the economic reliability and environmental performance of wave and tidal-energy power farms.
