… Of the cost centres that combine to result in Levelised Cost of Energy (LCOE), O&M costs play a significant part. Several developers have calculated component costs, demonstrating how they can become commercially competitive with other forms of renewable energy. However, there are uncertainties relating to the O&M figures that can only …

… government and devolved administrations. Attention has been drawn to this resource as a number of locations with high tidal current velocity have recently been leased by the Crown Estate for … velocity is too low for any power generation. However, it has been proposed that a portfolio of diverse sites located around the UK will deliver a firm aggregate output due to the relative phasing of the tidal signal around the coast. This paper analyses whether firm tidal power is feasible …

… One of the key challenges in marine energy is to achieve funding for commercial-scale project … the necessary capital investment, the expected profit margins, and the corresponding cost of capital. The paper examines this relationship for tidal current schemes and provides a method … de-risk early-stage project initiatives. The possibility to select a preferred ratio of ‘capital investment’ to ‘profit’ widens the circle of potential investors and accelerates the …

… This paper presents a detailed parametric analysis on various input parameters of two different numerical models, namely Telemac3D and Delft3D, used for the simulation of tidal current flow at potential tidal energy sites in the Pentland Firth in Scotland. The motivation behind this work is to investigate the influence of the input parameters on the above 3D models, as the majority of past research has mainly …

… Two different concepts of wave energy converter coupled to the novel C-GEN linear generator have been studied numerically, including the evaluation of different buoy sizes. The first concept has a slack connection between the buoy and the … system with active rectification. The radiation forces originating from the oscillatory motion of the buoy have been approximated using the transfer function in the frequency domain and the …

… and impacting on the design conditions. Changes to the wave climate depend on the strength of the current and the relative wave direction. SWAN simulations of the wave climate around the Orkney Islands, with and without currents, show that considerable changes in the wave climate occur near sites of interest to wave and tidal energy project developers. Using circular statistics the effect of …

… to additional, associated, expense. Overdesign is commonly driven by a limited understanding of the conditions at the deployment site. The RealTide project aims to tackle this conservative design by producing an open-access database of field and experimental data, providing a fuller understanding of the spatial and temporal variation of these conditions and the interaction of real-world …

… Despite this, currents are often ignored and wave buoy data is processed without consideration of the current or the wave-current interaction. This data is subsequently used in design, yet sea … may have significant errors. Here we present a novel framework for the processing of wave buoy data to account for the effect of a current. We use a mesh adaptive direct search (MADS) algorithm to solve for the current and …

… 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 …

… 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 …

… Anglesey. In order to investigate the disturbance to the local flow field due to the operation of tidal arrays and evaluate the extractable power at the site, a two-dimensional depth-averaged shallow water model of the naturally occurring tidal dynamics of the south-west UK and Irish Sea has been developed and validated. In the model, the effect of …
