… 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 …

… in resource rich deeper more distant waters. The development in these fields is often ahead of policy, regulation and infrastructure. Previous studies often utilise spatial analytics to … make assessments but often overlook grid requirements. In order to address this issue a series of spatial analytic and electrical power flow models have been established to form a novel … power flow dispatch model. It was found that sensitivity analysis was needed at each stage of the modelling process. However, it forms the basis of strategic development tool that could be …

… Wave Energy Converter structures are associated with the highest percentage share of LCOE costs, however, existing geometry optimization studies just consider maximization of power production and, in some cases, mass as a proxy for structural costs. How to include cost … discussed here. Two different methodologies - depending on the available information and goal of the study - are presented, and example cases for these are given. The results show the …

… This work investigates potential cost reduction trajectories of three emerging offshore renewable energy technologies (floating offshore wind, tidal stream, … SET-Plan levelised cost targets. Component-based experience curves have been applied as part of the methodology, characterised through the comparative maturity level of each technology-specific cost centre. The resultant early-stage target costs are then compared …

… predictable renewable energy. New technology is needed to decrease the levelized cost of energy and to make this energy sector competitive in the energy market. A key area where … costs is mitigating the hydrodynamic load fluctuations, and thus increasing the fatigue life of the turbine. Here, we formulate a passive morphing blade concept that aims to mitigate the … elastically can suppress virtually all fluctuations without varying the mean loads. The effect of the hydrodynamic and blade's inertia, the material damping, and the radial shear stress, …

… generators and energy storage are becoming cost competitive. Diesel usually provides about 10% of the demand because most renewables are non-dispatchable and thus the complete decarbonisation … storage and renewable generation capacities. Here a framework for the design and optimisation of HES using wind, wave and solar generation and DSM is introduced. For the Mediterranean it is … has lower benefits because waves act as an energy store for the wind. Thus, the combination of wave energy converters (WECs) and wind turbines significantly reduces the need for backup …

… revenue, and reducing unexpected maintenance will reduce operation and maintenance cost. Both of these help to reduce levelized cost of energy, in order to enhance tidal energy competitiveness. This paper presents a novel control … to reduce the loadings on tidal current turbines, while still enabling a significant amount of the available power to be extracted. The control strategy is based on adjusting the axial …

… Much attention has been paid in recent years to the determination of design loads for moored floating structures and the application of established methodologies for fixed structures have been found to be ineffective. This paper experimentally investigates extreme responses of a lazy S moored 1:20 scale model of Mocean Energy’s Blue Star wave energy convertor (WEC) …

Consequently, the choice of renewable energy technologies should be based on a comprehensive assessment addressing the … that are affected. Clean energy technologies are traditionally evaluated on the basis of their techno-economic performance. Such an approach penalises emerging energy technologies … that are generally more capital-intensive given their innovation requirement and the lack of support mechanisms facilitating their industrial roll-out. In this paper, a multi-criteria …

… This paper examines technical and non-technical factors that are critical to the viability of commercialization of wave energy converters in off-grid luxury resorts and small utilities. Critical factors are found by investigating Levelized Cost of Energy, and using the tools PESTEL and Porter’s five competitive forces. Identified factors …

… could be achieved through blades that passively and elastically adapt their camber and angle of attack to counteract unsteady flow conditions. Firstly, we discuss the underlying principles of unsteady thrust mitigation. We show that complete cancellation of the thrust fluctuations would be possible if every blade section could pitch passively and …

… 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 …
