HydroQuest
HydroQuest SAS is a French developer of vertical-axis turbines, generating electricity from river and tidal currents. The company was founded in 2010, in Meylan, Grenoble, and is based in the Inovallée science park. They have installed several small in-river turbines, in France and French Guiana. They also tested a 1 MW tidal stream turbine off the coast of Brittany from 2019 to 2021. HydroQuest and other partners are developing the 17.5 MW FloWatt project, comprising seven tidal stream turbines, expected to be built by 2027. Device concept The HydroQuest turbine is a double vertical-axis design, with counter-rotating blades inspired by Darrieus and Achard turbines. The river turbine can be adapted for most rivers with a depth of greater than . The tidal stream turbine design has two pairs of turbines stacked vertically on two parallel shafts. Each turbine has three blades, and the upper turbine is rotated 60° relative to the lower turbine, so the blades are ...

Paimpol–Bréhat Tidal Farm
The Paimpol–Bréhat tidal farm is a tidal stream turbine demonstration site, located northeast of Île-de-Bréhat near Paimpol, Brittany, France. It was initially developed by Électricité de France (EdF), initiated in 2004 and construction work began in 2008, but the project was subsequently cancelled by EdF in 2018. This project was to use OpenHydro turbines, with two briefly installed in 2016, but they were later removed. Paimpol–Bréhat is now used as a test site, owned by EdF and managed with support from Seeneoh and Bretagne Ocean Power. In September 2022, the 2 MW three-phase AC grid connection was upgraded, allowing devices to be connected above the water without the need for divers. The test site is about 10 km offshore and covers a rectangular area approximately 140 m × 250 m. Water depths vary across the site at 26 m to 42 m below LAT, with a tidal range of about 11.5 m. Telemac 2D modelling gives a depth averaged velocity o ...

Génissiat Dam
The Génissiat Dam ( French: ''Barrage de Génissiat'') is a hydroelectric dam on the Rhône in France near the village of Injoux-Génissiat. Construction began in 1937, but was delayed by World War II, and the dam did not start generating power until 1948. By 1949 it had the greatest capacity of any dam in Europe. Background The concept of damming the Rhone had been discussed since the 19th century. In 1906 the Harlé-Blondel-Mähl group published a proposal for a great dam at Génissiat. They were supported by the Groupe Giros-Loucheur and by Schneider. They had to compete with a rival proposal by a Franco-Swiss group, and both groups appealed to geologists to support their claims. The French speleologist and expert on limestones Édouard-Alfred Martel declared that the Génissiat scheme was pure folly: It would be impossible to anchor the dam in the limestone, which was anyway porous and would not retain the water. The Swiss Maurice Lugeon, a specialist in large dams, refut ...

Tidal Power
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun. Among sources of renewable energy, tidal energy has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability. However many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed and that economic and environmental costs may be brought down to competitive levels. Historically, tide mills have been used both in Europe and on the Atlantic coast of ...

European Union
The European Union (EU) is a supranational union, supranational political union, political and economic union of Member state of the European Union, member states that are Geography of the European Union, located primarily in Europe. The union has a total area of and an estimated population of over 449million as of 2024. The EU is often described as a ''sui generis'' political entity combining characteristics of both a federation and a confederation. Containing 5.5% of the world population in 2023, EU member states generated a nominal gross domestic product (GDP) of around €17.935 trillion in 2024, accounting for approximately one sixth of global economic output. Its cornerstone, the European Union Customs Union, Customs Union, paved the way to establishing European Single Market, an internal single market based on standardised European Union law, legal framework and legislation that applies in all member states in those matters, and only those matters, where the states ...

Front-end Engineering
Front-End Engineering (FEE), or Front-End Engineering Design (FEED), is an engineering design approach used to control project expenses and thoroughly plan a project before a fix bid quote is submitted. It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning. Overview FEED is basic engineering, which comes after the Conceptual design or Feasibility study. FEE design focuses the technical requirements as well as rough investment cost for the project. FEED can be divided into separate packages covering different portions of the project. The FEED package is used as the basis for bidding for Engineering, Procurement and Construction contracts ( EPC, EPCI, etc) and is used as the design basis (or Basis of Design). A good FEED will reflect all of the client's project-specific requirements and avoid significant changes during the execution phase. FEED contracts usually take around 1 year to complete for larger- ...

Normandy
Normandy (; or ) is a geographical and cultural region in northwestern Europe, roughly coextensive with the historical Duchy of Normandy. Normandy comprises Normandy (administrative region), mainland Normandy (a part of France) and insular Normandy (mostly the British Channel Islands). It covers . Its population in 2017 was 3,499,280. The inhabitants of Normandy are known as Normans; the region is the historic homeland of the Norman language. Large settlements include Rouen, Caen, Le Havre and Cherbourg-en-Cotentin, Cherbourg. The cultural region of Normandy is roughly similar to the historical Duchy of Normandy, which includes small areas now part of the departments of Mayenne and Sarthe. The Channel Islands (French: ''Îles Anglo-Normandes'') are also historically part of Normandy; they cover and comprise two bailiwicks: Bailiwick of Guernsey, Guernsey and Jersey, which are British Crown Dependencies. Normandy's name comes from the settlement of the territory by Vikings ( ...

Raz Blanchard
The Alderney Race is a strait that runs between Alderney and Cap de la Hague, a cape at the northwestern tip of the Cotentin Peninsula in Normandy. A strong current runs through the race north of the Passage de la Déroute, a treacherous passage separating the Cotentin from the Channel Islands. The current is intermittent, varying with the tide, and can run up to about during equinoctial tides. The French call it ''Raz Blanchard''. In Norman French it is called ''L'Raz''. Location The Alderney Race is across and located roughly between Alderney, in the Bailiwick of Guernsey, and La Hague, France. It constitutes the northeastern limit of the Gulf of Saint-Malo. Sea conditions When the wind and the race current flow in opposite directions, the sea becomes particularly chaotic: wave heights can reach and have wavelengths smaller than . The waves break with violence, thus making shipping conditions particularly dangerous. On the contrary, when the wind and the stream flow in ...
