Quirapas and Narasimalu
This workshop looks at the opportunities and barriers to local adoption of ocean renewable energy in islands and remote coastal areas of the Asian region from the perspectives of various stakeholders and the possible solutions to address the challenges. It also tackles the crucial roles of the different stakeholders (academia, policy-makers, industry and end-users) that each has to play to…

In the present work the wave energy propagation patterns in the western side of the Iberian nearshore were evaluated. This assessment takes into account the results provided by a wave modelling system based on spectral phase averaged wave models, which considers subsequent computational domains with increasing resolution towards the coast. The system was previously validated against both in…

Australia has considerable wave and tidal ocean energy resources. Development of the emerging ocean renewable energy (ORE) industry in Australia offers opportunities to build Australia's blue economy, while actively contributing to committed carbon mitigation measures. Many interdisciplinary challenges are currently hampering development of the industry in Australia, and globally, including…

Oregon Department of Energy
In 2017, the Oregon Department of Energy, recognizing that the energy world has changed
dramatically since the 1970s, introduced HB 2343. The bill charged the department with developing a new Biennial Energy Report to inform local, state, regional, and federal energy policy development and energy planning and investments. This report – based on analysis of data and information collected… - Journal Article:

The extraction of kinetic energy from tidal flows is an interest of the renewable energy industry with large scale assessments of the potential resource already conducted. These assessments however, use the natural kinetic energy flux as the primarily metric of the available resource. This approach has significant limitations when it is applied to tidal channels, particularly those tidal…

Over the next decades, tidal stream energy aims to become a fully commercially viable energy source. For this purpose, complete knowledge regarding tidal stream resource assessment is essential. In this context, the International Electrotechnical Commission has developed a technical standard for the assessment of the tidal stream resource, “IEC 62600-201 TS: Marine energy - Wave, tidal and…

In many regions strong tidal flow occurs only in areas with restricted water depths, typically within estuaries or rias. Although in some of these areas the depth constraint may preclude the exploitation of this resource, in others it is exploitable – and substantial. The objective of this work is twofold: (i) to develop a tool, the Tidal Stream Exploitability (TSE) index, to facilitate the…

The Orkney archipelago has a rich heritage that includes the Heart of Neolithic Orkney World Heritage Site, Viking settlements, harbours supplying Hudson's Bay Company ships, and the wartime naval base of Scapa Flow. This rich history has left its mark on the seabed but accurate maps showing the location and character of surviving seabed archaeology do not exist to the same…

Hydrodynamic changes imposed by tidal energy converters on extracting energy on a real case scenario
The development on tidal turbine technology is ongoing with focus on several aspects, including hydrodynamics, operation and environment. Before considering an area for exploitation, tidal energy resource assessments in pre-feasibility energy extraction areas must include the relevant characteristics of the device to be used. The present paper uses the momentum source approach to represent a…

Tides can be a vast and predictable source of renewable energy. Due to the solar and lunar influx on our planet, they move large amounts of water periodically, and this energy can be harnessed using devices designed and positioned adequately, such as current turbines. However, the relation between the energy obtained with actual devices and the economic and environmental cost of their…

Energy from marine currents offers the promise of regular and predictable electrical generation at higher power densities than other renewables. The marine current resource is potentially large but mainly concentrated in a number of sites around the world. The power density for a horizontal axis turbine operating in such currents has a similar form to that of a wind turbine and is dependent on…

During the last decade, tidal stream and wave energy technologies have made significant progress. A number of large-scale prototypes have been deployed around the world. In this article, the recent development in some western countries and China is presented. Taken as the representatives from European and American continent, UK, Portugal and US are chosen to compare with China in resource…

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…

Malaysia is heavily dependent on non-renewable energy sources for electricity generation, particularly fossil fuels such as coal, oil, and gas. However, the alarming increase in CO2 emissions and the depletion of fossil fuel reserves have given rise to imminent challenges in meeting the strong demand for electricity in Malaysia. Thus, this paper explores various types of tidal…

The paper combines hydrographic surveying techniques with numerical modelling to evaluate the spatial and temporal distributions of tidal power in a confined channel located in Portugal (Faro Channel in the Ria Formosa). The channel is characterised by strong currents with depth-averaged velocities exceeding 2 m s−1. The model was successfully validated against harmonic analysis…

During the last years the interest of supplying the energy needs by means of renewable energy sources has risen sharply. The objective of this work is to investigate the viability of the implementation of a tidal farm to fulfill the electricity demands of the Port of Ribadeo, which is located in a tide-driven estuary (Ria de Ribadeo, NW Spain). For this purpose a 3D hydrodynamic model of the…

With lack of convergence on any single wave or tidal technology, test centres have a unique role in the marine renewable energy industry. Test centres facilitate real testing at sea for devices and components at various TRLs (Technology Readiness Level), reducing the time, cost, and risks faced by marine energy developers. META (Marine Energy Test Area) is a £2.7M project managed…

In order to facilitate development of tidal power, a high-resolution survey with unprecedentedly fine grids has been made for marine hydrokinetic (MHK) energy at the seashore of New Jersey (NJ) and its neighbor states (Tang, Kraatz, Qu, Chen, Aboobaker, Jiang.

To predict tidal current movement accurately is essential in the process of tidal energy development. However, the existing methods have limits to meet the need for accuracy. Recently, artificial intelligence technology has been widely applied to solve this problem. In this paper, a tidal current prediction model combining numerical simulation with deep learning methods is proposed. It adopts…

The first and a crucial step in development of tidal power, which is now attracting more and more attention worldwide, is a reliable survey of temporal and spatial distribution of tidal energy along coastlines. This paper first reviews the advance in assessment of tidal energy, in particular marine hydrokinetic (MHK) energy, and discusses involved challenges and necessary approaches, and then…
