The world continues to move forward in search. clean and sustainable energy to bury forever the dependence on oil, coal and gas. Renewable sources are increasingly used to reach electricity, and others such as geothermal, hydroelectric or wave energy are added to solar and wind power generated from waves. But now, a Brazilian company has created a turbine to harness the propulsion of underwater currentsa world of all hitherto unexplored possibilities.
TidalWatt has developed a new generation of underwater turbines designed to extract energy from the ocean in a completely sustainable way. According to Mauricio Queiroz, founder and CEO of TidalWatt, the oceans are currents have already been extensively mapped and characterizedIt has become the only safe renewable energy source due to its stability and predictability.
These turbines act similarly, but use underwater currents, as wind turbines do when harnessing wind power in the atmosphere.
Three times more energy than a wind turbine
According to the company’s website, a TidalWatt turbine with a diameter of 3 meters can practically generate 5 MW of energy at a current of 1.87 knots. The same power delivered by a wind turbine with a diameter of 180 meters.
This is a remarkable efficiency case: the TidalWatt turbine with a diameter of 60 times smaller produces the same power and also due to the constant availability of the source, It can generate power 90% of the time, as opposed to 30% that a wind turbine produces on average.
“This means that these turbines, which are 3,600 times smaller in terms of coverage, can produce three times as much energy,” explains company president Mauricio Queiroz.
Company plans to install its turbines in places with an average current speed of more than 1 nautical mileIt produces 5 MW with turbine capacity ranging from 70% to 95%.
This is not a reference generation, because it is far from it. Based on the average consumption in Brazilian homes, each appliance can power approximately 22,800 families.
TidalWatt declares its commitment to the conservation and protection of marine life. Responsibles say the installation sites were chosen away from coral reefs to protect the surrounding ecosystems. Not only that: “Artificial reefs will be created at the base of the turbines so that various marine species can safely live and reproduce.”
Alliance with the John Cockerill Group
For the development of the first test model, TidalWatt has partnered with the John Cockerill Group, which is dedicated to developing large-scale technology solutions. This prototype setup and recently obtained official permission from the state of Rio de Janeiro to conduct testing with the Brazilian National Institute of Metrology, Quality and Technology (INMETRO).
“We are ready technically and scientifically. “LabOceano’s testing will help us take action to launch our subsea power plant projects and will open up investment opportunities for anyone who wants to have the latest form of clean and renewable energy generation with all the benefits that come with it.”
