Renewable energy is plentiful; we need only develop the technology to harness and distribute it efficiently and economically. The conversion of energy to electricity continues to be an area of interest for engineers and researchers. Tidal energy has been classified as one of five energy innovations that could transform our world—the others being fuel cells, lithium–air batteries, the smart…

Thomaz et al.
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 be reduced through lessons learned at sea. This…

This study quantifies 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…

Milone et al.
The importance of renewable energy exploitation reduces the energy dependence on fossil fuels. Despite technological progress, in several remote areas and small islands the energy production is nowadays dominated by the utilization of fossil fuels. With new, increasingly stringent laws on polluting emissions and the need to lower production costs, it is necessary to exploit as many renewable…

This work assesses the effect of long-term changes in the wave climate on the optimal sizing and performances of oscillating water column wave energy converters along the coastline of the Mediterranean basin. Trends are evaluated based on the projections of future wave climate to 2100 delivered by the Climate Data Store of the Copernicus Climate Change Service under representative atmospheric…

Ruiz-Minguela et al.
The development of new renewable energy technologies is generally perceived as a critical factor in the fight against climate change. However, significant difficulties arise when estimating the future performance and costs of nascent technologies such as wave energy. Robust methods to estimate the commercial costs that emerging technologies may reach in the future…

Baca et al.
As the world faces increasing threats from climate change, the importance of developing renewable energy technologies and reducing their costs has similarly increased. Marine energy technologies (which include wave, tidal, ocean current, ocean thermal, and salinity gradient resources) are a nascent suite of renewable technologies. There are vast marine energy resources available around the…

Present study deliberates on the numerical analysis of a new, bean-shaped, multi-body floating wave energy converter (BFWEC) using an open-source time-domain modeling tool called WEC-Sim (Wave Energy Converter SIMulator). The proposed device is a directionally-insensitive, floating-point absorber with a set of bean-shaped floats attached circumferentially around a central cylinder or buoy (CB…

Goss et al.
Costs of tidal stream energy generation are anticipated to fall considerably with array expansion and time. This is due to both economies of volume, where arrays comprising of large numbers of turbines can split fixed costs over a greater number of devices, and learning rates, where the industry matures and so arrays of the same size become cheaper due to lessons learned from …

This deliverable, D7.9 LCOE Analysis for baseline project scenarios, aims to present the baseline financial models built in the Exceedence software, ExFin, and exported to a summary report for a range of combined offshore renewable energy projects, based on data provided by the consortium partners and from wider industry information.
This report introduces the metric Levelised Cost of…

Weinstein et al.
Principle Power Inc. and National Renewable Energy Lab (NREL) have completed a contract to assess the technical and economic feasibility of integrating wave energy converters into the WindFloat, resulting in a new concept called the WindWaveFloat (WWF). The concentration of several devices on one platform could offer a potential for both economic and operational advantages. Wind and wave…

The cost metrics presented throughout this document are derived or estimated from known Pelamis P2 costs for components that were selected based on optimising the Levelised Cost of Energy (LCoE) for the Pelamis as a whole.
All of the costs included in this document are discussed in more detail in the relevant cost metrics reports:

This report sets out the Pelamis experience with Cost of Energy (CoE) modelling, summarises the various tools developed and results obtained through the programme, and highlights the key insights it gave. It also draws conclusions and recommendations from the experience.
This report is written to provide insight into how the Pelamis models and projections moved and developed with time…

The System Advisor Model (SAM) developed by the National Renewable Energy Laboratory with funds by the U.S. Department of Energy is a free, publicly available modeling software designed to evaluate renewable energy system design, performance, and project economics. Since the software’s launch in 2007, new versions have been released annually, adding to the collection of technologies and…

McCabe and Haji
To assess the techno-economic prospects of wave energy devices, the metric typically used is the levelized cost of energy (LCOE). For early-stage projects where proper LCOE calculation is premature, LCOE proxies such as ACE (the ratio of average climate capture width and characteristic capital expenditure) are used instead. However, LCOE-based comparisons fail to capture some of wave energy’s…

The deployment of offshore wind, wave, and ocean current technologies can be coordinated to provide maximum economic benefit. We develop a model formulation based on Mean-Variance portfolio theory to identify the optimal site locations for a given number of wind, wave, and ocean current turbines subject to constraints on their energy collection system and the maximum number of…

Can pressure retarded osmosis (PRO) reduce or eliminate diesel dependency in Bella Coola, British Columbia? This study looked into the possibility of using PRO to replace diesel in Bella Coola by analyzing the energy potential of six watersheds in the region, comparing the levelized cost of electricity (LCOE) of PRO to current diesel prices, and examining potential environmental impacts…

Wave Swell Energy Ltd (WSE) has commissioned the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) to provide an independent analysis of the cost benefit for using wave power as a reliable supply of renewable energy. Previous studies from CSIRO have suggested that the strength and reliability of wave power along Australia’s southern coastline has the potential to…

Based on multi-objective particle swarm optimization (MOPSO) algorithm, with considering levelized cost of energy (LCOE) and exergy efficiency as two different objective functions, an innovative Organic Rankine Cycle (ORC) model based Ocean Thermal Energy Conversion (OTEC) system is investigated for trade-off Pareto optimization. In the present study, six key parameters including evaporating…

Wind-wave hybrid floating systems are subject to active research and development in academia and industry. Industrialization of hybrid wind-wave energy systems will benefit from modular designs, allowing floating platforms to be used with or without wave energy converters (WECs). This work explores the design process to use oscillating water column (OWC) WECs as modular add-on features to…
