Tidal Stream Marches on in Europe

are gaining ground.”Tidal turbines harness the lateral flow of currents to produce clean, predictable renewable energy.The ocean energy industry sees 100GW of tidal and wave capacity being built in Europe by 2050, providing 400,000 jobs and supplying 10 percent of the EU’s current electricity needsFrance has one of the best tidal resources in Europe, a workforce with engineering skills, and coastal supply chains ready to service the deployment of this new industry.  As part of the EU SET plan, targets have been set to reach 10€c/kWh by 2030, well below offshore wind costs

European Commission Okays French Backing of Tidal Energy Test Site

The European Commission has found a French project promoting electricity generation from tidal energy to be in line with EU State aid rules. The measure will contribute to the EU's energy and climate goals without unduly distorting market competition, the Commission said.The Normandie Hydro plant is a demonstration plant for producing electricity from tidal energy. It will be developed by OpenHydro and operated by EDF EN and will be located at Raz Blanchard, west of the Cotentin peninsula, on the English Channel. The demonstration plant will comprise seven turbines with a power generation capacity

German North Sea Wind Production on the Rise

Offshore wind power plants in Germany's North Sea produced 5.15 percent more electricity from January to June than in the same period in 2017 at 8.17 terawatt hours (TWh), TenneT, the grid operator for the region, said on Thursday.On the day of highest capacity use, TenneT said 4,431 megawatts (MW) were tapped. This is equivalent to four to five big nuclear plants, or 44.4 percent of Germany's existing nuclear reactor total.North Sea wind accounted for 15.1 percent of total German wind production in that period, although that is not a fixed number because it depends on weather patterns.If a

on Tuesday it had opted to keep capacity at 49 percent after the sea water cooled to 24 degrees, while closely monitoring water temperatures as the warm weather continued.The 865-megawatt (MW) pressurized water Ringhals 2 reactor is one of four reactors, which produce around 20 percent of Sweden's electricity. While Ringhals 3 and 4 are still online, Ringhals 1 is shut for annual planned maintenance.(Reporting by Anna Ringstrom Editing by Alexander Smith

Equinor Explores Floating Wind Turbines to Power N.Sea Oilfields

Norway's Equinor said on Tuesday it is considering whether to build a pioneering offshore wind farm with floating turbines to supply electricity to two North Sea oilfields as part of a strategy to curb greenhouse gas emissions.The project at the Gullfaks and Snorre oilfields would cost around 5 billion Norwegian crowns ($592 million) and could reduce Norway's emissions of carbon dioxide by more than 200,000 tonnes per year, Equinor said."This could be the first time an offshore wind farm is directly connected to oil and gas platforms," state-controlled Equinor said in a statement.

Marine Survey Work Starts for Greenlink Interconnector

The subsea field work for the Greenlink interconnector, one of Europe’s most important infrastructure projects, gets under way with the launch of the first of MMT’s survey vessels, MV Franklin.The offshore and nearshore surveying along the proposed route of the electricity link between the UK and Ireland is expected to take approximately 40 days, depending on weather conditions. MMT were awarded the contract for the Greenlink Marine Survey (GMS) by Greenlink Interconnector Ltd in August.Further survey work along the 170km marine route will be undertaken by vessels MV Seabeam, MV Edda Fonn

Nexans Wins Triton Knoll Wind Farm Contract

. grid.Located around 30 km off the coast of Lincolnshire, Triton Knoll is being developed by Innogy Renewables UK Ltd, in partnership with J-Power and Kansai Electric Power. It has a planned installed capacity of approximately 860 MW and, once operational will be capable of generating enough renewable electricity to supply over 800,000 UK households. To export the energy generated by the wind farm to the grid, Triton Knoll will rely on Nexans’ 220 kV land export cables, which will transmit the power over a total distance of around 57 km from landfall near Anderby to the new Triton Knoll substation

Subsea’s Future is Blowin’ in the Wind

GWh annually, GE said.Higher power producing turbines offer efficiencies across an entire project by reducing risk and costs for installation (fewer turbines installed), operation, maintenance and repair for developers, which makes offshore wind projects more profitable and ultimately lowers cost of electricity for consumers. The Haliade-X is designed to offer greater power generation efficiency, with a 63 percent gross capacity factor five to seven points above the current industry benchmark, according to GE. Therefore, it will produce more energy per MW installed.Ideol Offshore, STX Europe Offshore

Mexican Wave Energy Project Moving Forward

Energy from the ocean breakers that pound Mexico’s Pacific Coast could soon be turned into electricity as an Israeli joint venture finalizes permits and financing for the country’s first wave energy plant.Wave power development has long lagged renewable rivals such as solar, but Eco Wave Power says it could prove an effective way to deliver power to coastal communities in countries such as Ghana or Kenya that have little access to electricity.“The ocean is the biggest renewable resource that we have and it’s completely untapped, and it has to change,” said Inna Braverman
