Offshore Wind Energy, Current,Tidal and Wave Energy andOffshore Electricity Grid Infrastructure

The ContextImportance of climate mitigation through development ofmarine renewable energy such as offshore wind farms,and ocean current, tidal and wave facilities.As well as generating energy, the oceans play a ne vitalrole in transmitting renewable energy through longdistance high voltage transmission lines and offshoregrid infrastructure.Marine renewable energy can play a vital role inmitigating and adapting to climate change and oceanacidification.Key example being energy and water nexus, and role thatrenewable energy can play in desalination of brackishand salt water to meet freshwater needs globally.Marine renewable energy planning and designs canenhance marine biodiversity and ecosystem , and theecosystem services benefits necessary to communities.

Marine Renewable Energy in the Context ofSustainable OceansOffshore wind farms and wave and tidal projects could havecomplimentary impacts on birds, fish, marine mammals,and marine and coastal ecosystem and support sustainableoceans industries such as fisheries and tourismFor example, appropriate implementation could enhancefisheries productivity through no-take zones and increasedfisheries breeding zones and habitat.Caution needs to be exercised with new technology. Forexample, electro-magnetic fields associated with the highvoltage transmission lines and hubs of proposed electricitygrids may have impacts on certain species (sharks, skatesand rays) and benthic organisms on the seabed.Ongoing monitoring and modification of offshore wind farms,current, tidal and wave projects, and related gridinfrastructure can positively address biodiversity andecosystem concerns through the construction,authorization, operation and maintenance, and theabandonment and reclamation of these facilities.

Small Island Developing States andLeast Developed EconomiesUnique and dual role of wind and ocean energy indeveloping small island states and the coasts of lessdeveloped countries to achieve sustainabledevelopment and poverty alleviation.Ongoing issues of capacity, technology development &transfer that need to be addressed.For example, offshore and on land wind farms (as wellas ocean energy), combined with hydrogenstorage/dams and hydraulic storage, can substitutefor imported diesel fuel electricity generation.Wind, ocean and other renewable energy can becombined with desalination facilities to alleviate thewater shortages caused by higher temperature andchanging precipitation patterns, thus assisting SIDSand developing countries to adapt to climate change.

Off Grid SustainableEnergy Solutions:Ramea Island,Newfoundland,CanadaThe electrical grid of Ramea Island relies on diesel andwind power and will incorporate a hydrogen storageand generator system. In this isolated remote powersystem, hydrogen will be produced from waterelectrolysis when the wind power output exceedsdemand. The hydrogen gas is placed in storagetanks. When the power output from the windturbines is not sufficient to meet the communityload, the stored hydrogen powers a generator whichprovides electricity for the community.

Global Future of Wind EnergyEurope is biggest growth market for offshore windfor next five years, but after that China will lead.Along with China, Brazil and India become active.The Middle East and North African market willgrow very quickly over with most of theinvestment from solar technologies replacing oil-fired power plants.Most growth in developing economies of India, theMiddle East and North Africa, Africa and LatinAmerica.By 2020, the markets outside of the Europe, US,Canada and China will be 50% of world demand.

Future Offshore Wind Technology for DeeperSeas : Floating Offshore Wind Farms

Sustainable Cities and Regions &Role of Sustainable Seas andRenewable Marine EnergyWater and Energy Nexus: RenewableEnergy and DesalinationSustainable London and LondonArrayState of Hawai’iGalapagos Islands and sustainableenergy development in a fragileenvironment

Water and Energy Nexus:Renewable Energy and DesalinationDesalination by renewable wind and solar energy is currentlybeing evaluated in a variety of European and internationalforums and projects.Windenergy modeling and studies of various wind energypowered desalination plants and prototypes underway.Important technological problems such as the intermittency ofwind, and counter measures such as electricity storage andhybrid energy systems are being considered.Replacing fossil fuel by renewable energy such as sun and windto desalinate seawater could reduce costly energy imports,eliminate greenhouse gas emissions, and support adaptationto climate change for higher temperatures, less precipitation,saline infiltration of aquifers, and growing water scarcity.Large scale desalination brings environmental challenges in theextraction of sea water and the release of heated brine intocoastal and marine ecosystems, but these concerns can bepartly addressed in the design of intake and outlet systems.
