Payne et al.
… typically requires fast and steady rotary motion. This article investigates the performance of a hydraulic transmission system based on Digital Displacement™ technology, which allows variable speed of the tidal current turbine rotor while maintaining constant generator shaft speed. The case study of a generic horizontal axis tidal turbine is considered. Control strategies based on rotor …

Greenwood et al.
… This paper presents results from numerical simulations of three Oscillating Wave Surge Converters (OWSC) using two different computational models, Boussinesq wave (BW) and Spectral wave (SW) of the commercial software suite MIKE. The simulation of a shallow water wave farm applies alternative methods for implementing a frequency dependent …

Ewing et al.
… For established technologies, reliability prediction either involves a statistical assessment of historical failure data, or a physics of failure approach based on dedicated accelerated testing. However, for low/mid Technology … tidal developers these common approaches are difficult. Thus, developers require a method of making reliability predictions for components in the absence of tidal turbine specific failure …

… Wave data analysis from a short-term deployment of a wave buoy and AWAC in the lee of a Hebridean island in the United Kingdom is discussed in this paper. Significant parameters … have been employed to fit the measured data. Results show that while the Atlantic facing side of the island is exposed to a predominant swell based wave regime, the area in the lee features …

… have made substantial progress towards commercialisation. Based on the successful testing of full-scale prototypes, pioneering tidal arrays are currently implemented by means of direct agreements between developers/investors and device manufacturers. The top-ranked risks … are directly intercorrelated as investor confidence mainly depends on track records of continuous device operation. Before becoming recognised as a fully mature electricity …

… the potential power system benefits that the UK stands to gain through the deployment of marine energy technologies (wave and tidal stream) in domestic waters. These system benefits are primarily due to the temporal and spatial offsetting of wave and tidal resource with other, more established variable renewables, such as wind and solar. Wave and tidal generation can be available at times of low wind or solar resource, helping to balance the overall renewable power profile. It has …

Pierart et al.
… In order to design and evaluate the behaviour of a numerically optimised wave energy converter (WEC), a recommended procedure is to initially … up until the full-scale is reached. At any point, an important step is the correct selection of the wave theory to model the dynamical behaviour of the WEC. Most authors recommend the selection of a wave theory based on dimensional …

… in Matlab/Simulink that has been used to study, analyse and improve the network integration of wave energy converters (WECs). It presents and discusses a generic, time domain, resource-to-wire model that can be used to explore the effects of: increased device numbers, array size and physical positioning; and the adjustment of control parameters. The three-dimensional wave field is modelled as non-stationary, with …

… today. Europe’s ocean energy resource is considerable. By 2050, ocean energy can deliver 100GW of capacity – equivalent to 10% of Europe’s electricity consumption today. Flexible and predictable, ocean energy complements … Europe’s technological advantage in ocean energy will ensure European companies a large share of a strong global market, as they do on offshore wind. With zero carbon emissions, ocean energy …

… constrained to a typical, short-term, lunar month-long period. We explore how the selection of particular timeframes skews findings of energy assessments, especially for cross-comparisons across studies. This exercise relies on metrics assessing the magnitude and variability of a tidal signal relative to longer-term nodal cycle quantities. Results based on UK tide gauges …
