Thorson et al.
Marine energy, including ocean waves, ocean currents, ocean thermal gradients, tides, and river currents, is a vast and untapped resource that can be harnessed to help enable the transition to renewable energy. Marine energy is an attractive renewable resource because of its energy density, predictability, and persistence. Further, marine energy has the potential to provide energy for utility-…

Beyer and Simonsen
The use of marine energies from waves and tides have been discussed since long, however sustained application is rare. Nevertheless, in recent years systems harnessing tidal streams in the MW scale have started commercial operation after a year-long test (OES 2019).
Tidal stream flows have – as compared to other renewable energy flows - a remarkably high predictability. However, this…

Ma et al.
With the increasing scarcity of fossil energy such as petroleum and the increasingly urgent requirements for ensuring energy security and protecting the ecological environment, the development of renewable and clean energy has become a common consensus and concerted action among countries and regions in the world. The proposal of China’s marine power and the “One Belt, One Road” initiative, as…

The present study analyses the combined offshore wind and wave resource potential along the Indian coast. The state-of-the-art ERA5 reanalysis datasets that provide wind fields at 100 m height have been used for the first time to assess wind resources along the Indian Coast. Further, wave parameters were generated using the WAVEWATCH III (WWIII) model. Long-term spatial air density was…

Richardson et al.
This study develops and implements an interdisciplinary framework to provide a holistic examination of the potential for tidal stream turbines (TST) to displace diesel generated electricity in remote coastal First Nations communities in British Columbia. In doing so it seeks to answer the following research questions: what is the distribution of practical tidal resources in the study region,…

Almoghayer et al.
Islands energy systems are often separated from mainland energy markets. Islands routinely rely on a single imported source of energy, which exposes islands to economic risks, and an increased likelihood of system failure. Integrating renewable energy into island energy systems can provide diversity of energy supply and improved system efficiency, potentially yielding cheaper energy for island…

With an increasing demand for ocean resources to fulfil the needs of an ever growing population, humanity has been pushed to utilise the ocean resources. To be successful in these efforts, they have been pushing technological development which in turn has increased the demand for power as most of these developments are power hungry. However, with the present power generation knowledge confined…

Ocean Thermal Energy Conversion (OTEC) relies on the thermal differences between ocean surface waters and cooler waters at c. 1000 m depth. The highest and most reliable thermal differentials are in the low latitudes, 20° either side of the equator, including the Pacific Islands region. Whilst in theory OTEC can utilize an inexhaustible amount of stored energy within the oceans, in practice…

We review wave energy conversion technologies for niche applications, i.e., kilowatt-scale systems that allow for more agile design, faster deployment and easier operation than utility scale systems. The wave energy converters for niche markets analysed in this paper are classified into breakwater-integrated, hybrid, devices for special applications. We show that niche markets are emerging as…

Ocean Energy Systems
Ocean energy is a dynamic and fast-growing sector of the blue economy. There are a number of sectors of the blue economy that depend on access to consistent and reliable energy, including offshore aquaculture, ocean observation, marine robotics and offshore data centers. These offshore applications will require new energy approaches. Ocean energy can provide solutions to support a variety of…

Oliveira-Pinto et al.
Offshore oil and gas platforms have very high-power demands, being the electric power supply usually provided by gas turbines operating with natural gas extracted from the field. Since fields are ageing, the amount of gas available for electric power production is declining. One common alternative is to feed those gas turbines with fuel diesel, which is an expensive solution at remote…

A feasibility study for the installation of Wave Energy Converters (WEC) in a Spanish Mediterranean port is evaluated in this paper. The final aim is to evaluate the possibility of building a new infrastructure which combines a breakwater and a WEC able to provide energy to the commercial port of Valencia. An estimation of the wave power potential is made according to existing databases from…

On July 9th, the Pacific Marine Energy Center (PMEC) and PacWave hosted national and international experts from government, academia and industry, and across maritime sectors, to explore future research and testing opportunities associated with the development of the PacWave testing facilities. This report summarizes the findings from the strategic break-out sessions presents major takeaways…

Marine Energy Wales
Developing marine renewable energy offers Wales a realistic opportunity to deliver a low carbon economy and reduce carbon emissions in response to the Climate Emergency declaration by Welsh Government in 2019. However, the benefits for Wales go far beyond clean energy.
Wales is working hard to gain the early mover advantage and, with ongoing support, can continue to position itself as a…

RenewableUK
The wave and tidal sectors represent a once in a generation opportunity to secure a new low carbon, indigenous source of electricity which delivers significant economic and industrial growth. The UK is home to some of the best marine energy resource in the world. It has an evolving, dynamic marine energy sector which is already achieving outstanding technology progression with many concepts…

Technological advances on the century-old ocean thermal energy conversion (OTEC) concept have advanced this renewable energy system to the point at which power-plant construction on remote islands is close at hand. Research and development efforts on OTEC have introduced new applications for an essential element of the system, namely, the deep, cold, nutrient-rich, pathogen-free sea water.…

The tidal currents in the region of South-Western sea of Korea can be utilized for the development of tidal current power, benefiting many fishing nurseries and nearby islands. Furthermore, it can contribute to promoting energy independent islands. This study focuses on floating-bridge type small tidal current turbine, which can be installed between the small islands limited space unlike large…

Applications including the offshore aquaculture, remotely operated vehicles, data acquisition systems, and desalination can be either supplemented or completely powered by renewable energy. The spar-buoy oscillating-water-column wave energy converter concept, typically studied for large scale wave energy production, can be re-designed to meet the power requirements of such applications, which…

Rapid population growth and industrialization have contributed to a dramatic decline in the supply of freshwater. As a result, desalination is an important choice to solve the global problem of water scarcity. Nevertheless, the hyper-saline by-product, the high capital costs, and the high energy demands currently met by fossil fuels are key obstacles to the widespread adoption of desalination…

In this research, for the study of solar radiation energy and estimation of GHI in the area of radiation component, data were collected for the years during 2005–2014 from ECMWF database. To investigate the ocean thermal energy conversion, vertical changes of water temperature were studied using UNESCO data as seasonal thermocline for the Caspian Sea. Moreover, to investigate the possibility…
