Hywind Floating Wind Farm
Now Delivering Electricity

Hywind Scotland, the first floating wind farm in the world, has started to deliver electricity to the Scottish grid. The 30-MW wind farm, operated by Statoil in partnership with Masdar, is located 25 km offshore Peterhead in Aberdeenshire, Scotland, and will power approximately 20,000 households. Hywind will provide clean energy to more than 20,000 homes.

Linked to the Hywind Scotland project, Statoil and Masdar will also install Batwind, a 1-MWh lithium battery storage solution for offshore wind energy. Battery storage has the potential to mitigate intermittency and optimize output.


Ecological Surveys on Impact
Of Wave Energy Converters

Plymouth and Exeter Universities have completed the first set of ecological studies as part of the EU Horizon 2020-funded Clean Energy from Ocean Waves (CEFOW) project. The research was carried out at the European Marine Energy Centre’s (EMEC) grid-connected wave energy test site.

As part of the CEFOW project, the ecological surveys will take place over three consecutive summers to investigate the cumulative impact of multiple wave energy converters (WECs) on the seabed habitat and associated ecosystem. Monitoring involves the use of nondestructive towed underwater video systems and baited remote underwater video systems to analyze species and habitats.

The multiyear data set will assist with understanding the degree of natural spatial and temporal variation of marine organisms at EMEC’s test site and provide information to marine energy stakeholders of any positive and negative effects so that they can be optimized and/or mitigated as wave energy technologies develop.


Six Renewables Companies
Awarded Support

The FORESEA program has approved six offshore renewable energy technology projects for support in its third call for applications. The awards highlight the leading role Europe plays in ocean energy globally, with continued strong demand for testing in European ocean energy centers of excellence from both EU and non-EU developers

FORESEA’s user selection board awarded a “recommendation for support” to demonstration projects led by the following technology developers to test at the indicated test center: Blackfish (EMEC); Bombora (EMEC); IDEOL (SEM REV); Interdrones (SEM REV); Kornwerderzand BV (DMEC); and Scotrenewables (EMEC).

Final confirmation of support will be granted to developers upon contract with the relevant test center.

The awards will provide a real boost to technology developers by allowing them to test their technologies at sea. It will also help them attract further investment and move along the path to industrialization.

The fourth and final FORESEA call for applications opened in October 2017 and aims to help technology developers from other offshore sectors transition into the renewable energy market. The call runs until June 29, 2018.


Ocean Thermal Energy
Conversion for Tropics

The Dutch company Bluerise has developed new technology to produce energy from the ocean in the tropics by using the temperature difference between surface water and water at depth.

In the tropics, more than a billion people live close to the coast, and more than half of the energy is used for air-conditioning, which causes large CO2 emissions.

Buildings can be cooled sustainably and at a much lower cost using ocean thermal energy conversion to generate electricity.

Bluerise is working on a project at the airport in Curacao and in the Montego Bay area in Jamaica.


Collaboration to Promote
Wind Tech in Shipping

The World Wind Energy Association (WWEA) has partnered with the International Windship Association (IWSA) in order to further promote the uptake of wind technology by the global shipping fleet. The WWEA will contribute decades of experience in driving industry transition and taking advantage of the power of wind energy technology to plot the commercial course toward full decarbonization. The IWSA, in parallel, will continue to bring together all parties in the development of a wind-ship sector to shape industry and government attitudes and policies.


Funds to Study Tidal
Turbine Impact

Acadia University’s Dr. Richard Karsten is the lead researcher of a project that will receive an Innovation Fund award from the Canadian Foundation for Innovation (CFI). The tidal energy project will receive $1,119,556 from CFI for state-of-the-art field equipment and high-end computing infrastructure.

In the Bay of Fundy, Canada has one of the world’s richest tidal resources and a world-leading test site for large grid-connected in-stream tidal turbines.

However, decisions regarding the development and regulation of the tidal energy industry are hindered by insufficient scientific evidence related to animal/turbine interactions and flow variability.

To fill these knowledge gaps, the funds will enable creation of the world’s first observation and prediction system for investigating the physical and biological marine environment in high-flow conditions at turbulence-resolving scales.


Rovco Contract to Inspect
Gwynt y Môr Wind Farm

U.K. subsea company Rovco has been awarded a three-year contract to support one of the world’s largest offshore wind farms, Gwynt y Môr, which lies 8 mi. off the coast of north Wales.

Gwynt y Môr generates enough energy for more than 400,000 homes.

Rovco will provide its Sub-Atlantic Mojave ROV from its fleet, kitted out with 3D inspection equipment, alongside traditional video, Teledyne BlueView sonar and cathodic protection analysis techniques.

The firm will supply inspection services to the 576-MW wind farm’s offshore assets as part of its ongoing maintenance plan.

The observation-class Mojave ROV is best suited to the strong currents found in the Liverpool Bay area.
