Abstract

Wave energy is gaining increasing attention in worldwide energy planning strategies as key enabling factor for reaching the ambitious carbon neutrality targets. Therefore, a seamless access to the energy resource is needed, as well as the productivity of various wave energy converters, to probe the potential of installing farms in a given location. This paper presents and uses the novel web-based MORE-EST Platform (Marine Offshore Renewable Energy – Energy Security Transition), which aggregates information for wave resource assessment, bathymetry and marine space use. This work includes the mathematical modelling of the underlying technology database: 1) an Oscillating Surge Wave Energy Converter, to discuss the importance of including directionality in productivity assessment; 2) a Heaving Point Absorber and its techno-economic optimisation, comparing various proxies for capital expenditures. Results demonstrate that: 1) neglecting directionality may lead to errors in the productivity estimation, up to 31% in a site with a narrow wave rose, and up to 46% in a site with a widespread wave rose; 2) different optimisation objectives lead to dramatically different devices.
