The bureaucracy slows the implementation of the marine elica – La Provincia

The absence of administrative authorizations balks the take off of offshore wind energy throughout Spain and, with it, the leading role that in this chapter of the fight against climate change is called to play the Archipelago. Technology advances, as demonstrated by the pilot projects developed in the Canarian coast, and the interest of investors increases, but the bureaucracy does not follow the same pace.

With the environmental and energy competencies grouped in the same ministry – Ecological Transition – it is political instability, the difficulty in forming a central government, which prevents progress.

This week, during the celebration of a day dedicated to marine wind turbines, the general director of the Wind Business Association (AEE), Juan Virgilio Márquez, encouraged the Executive to take a step forward and establish an auction schedule as well as It does regularly with other technologies. For this, he recommended including a specific chapter in the National Integrated Energy and Climate Plan.

Europe does advance

Spain is falling behind. Last year, 2.65 gigawatts of wind power were installed in Europeoff shoreand the total existing to date is 19 gigawatts. It is true that the high depth of the Spanish coasts has so far prevented the country from being in the top positions, but the tests carried out in the waters of the Islands with floating platforms are a success.

The Elisa project, developed by the architectural and engineering consultancy Esteyco, continues to be developed alongside the Canary Islands Oceanic Platform (Plocan), in the bay of Las Palmas de Gran Canaria. The wind turbine located there pours the energy into the electricity grid. However, the most important part of this project goes through the notable reduction of transport and installation work. It crawls along the folded marine surface and rises taking advantage of the telescopic structure of its mast once it reaches the indicated place.

Also near the Plocan was until three weeks ago the prototype led by engineering EnerOcean, Andalusian root and based in the capital of Gran Canaria. He tested for four months – three were initially planned – his W2Power technology. In addition to also seeking a reduction in installation costs, this ingenuity doubles the production capacity with very low space consumption by housing two turbines of six megawatts of power on a single platform.

It is a prototype built in the shipyards ofPort of La Luz and Las Palmasto one sixth of the actual size. During the time he spent in the water, he demonstrated resistance to large waves. "We are still analyzing the data in detail, but we are very happy with the result," explained the company's technical director, Pedro Mayorga.

Among the parameters tested are the maximum angles reached by the machine and the correct orientation. Because another of the improvements introduced by W2Power is the ability to rotate through a central axis so that the blades maximize the wind force at all times.

For the development of the prototype, EnerOcean and its partners invested two million euros. The test has encouraged them to start the marketing phase. "The full-scale prototype is already designed," Mayorga announced. The demand exists and the logic dictates that the waters that have hosted the first test on the ground are also capable of housing the first units capable of pouring energy into the network.

In large part, that will depend on the momentum that this technology receives from the Administration. Thegeneral electionsTomorrow they are another opportunity to consolidate an Executive with greater capacity to make decisions than the current one.
