We often talk about offshore wind but where are we with this renewable source? What are the offshore plants operational and which are under construction? This September, a report was produced which offers a detailed overview of the spread of offshore wind farms. The report is available free of charge in PDF and has not received any third party funding for its writing. The entire analysis was handled by Main (e) International Consulting LLC.

From a first overview, we note that the projects already started mainly concern Japan with 8 offshore plants. Some of which will go into operation during the next year, for others extensions are planned but the dates have not yet been defined. Without making any distinction between the technologies used (Spar, Semi Sub, TLP, floating ... ..) and without making a difference between operational projects in the test phase and projects that are only in the initial phase, we can propose a list of the countries that are approachingoffshore wind with a defined number of implants.

  1. Japan - 8 plants
  2. Norway - 4 plants
  3. USA - 3 plants
  4. France - 3 plants
  5. Netherlands - 3 plants
  6. Germany - 2 plants
  7. Sweden - 2 plants
  8. Spain - 1 plant
  9. Denmark - 1 Plant
  10. United Kingdom - 1 Plant

When it comes to offshore wind, the floating turbines they represent a delicious dish for companies in the sector. In the waters of the Mediterranean, the first floating plant in the world is being tested. An article published on Financial Times explains that the Japanese interest inoffshore wind grew up following the Fukushima disaster. Japan is strongly interested in technology offshore due to the scarce availability of terrestrial soil. An industry engineer received $ 160 million in funding to initiate a preliminary test to set up wind turbines right in the Fukushima area. If the test phase is successful, the area will be able to host 150 floating wind turbines with a total capacity of one gigawatt by the end of this decade.

Even if theoffshore wind energy it is more expensive thanterrestrial wind power, comparing costs to energy production, the advantage remains: the wind is stronger and more constant in the open sea, so offshore energy production is more reliable. This was demonstrated by the tests onoffshore wind implemented in Germany. Furthermore, to establish the cost ofwind power it is also the estimate of the land. In countries like Japan where land is quite expensive, the economic gap between onshore wind and offshore wind can be negligible.
