There’s no doubt that tidal power is acutely backward behind other forms of renewable energy like wind and solar power. However, as two-thirds of the Earth’s apparent is covered by water, we’d be crazy not to try and accouter energy from water that’s continuously in motion.

Given the high costs of creating new technology and the fact that there is yet to be an agreed upon design that works, the tidal energy industry is yet to take off. Germany based company, REAC Energy GmbH wants to change that.

They have developed the StreamCube, a scalable, cube-shaped water wheel that might be what the market has been cat-and-mouse for to make tidal power commercially viable. The device is agnate to the accepted water wheel, only it’s anchored deep underwater and uses currents to aftermath energy.

The module works using vertical rotor axes that are set in motion by the burden of flood water. Depending on the accession of the rotor, the blades fold on or off. The StreamCube units can also be lined up or ample depending on what they are being used for.

Tides are caused by the gravitational pull of the sun and the moon on the ocean. They are approved and anticipated and they aftermath less alternate energy than wind or solar power. Check out NASA’s decision of the earth surface currents:

REAC afresh completed testing the StreamCube in Orkney with the help of all-embracing marine contractors, Leask Marine. This location, off the north coast of Scotland, has become a hot-spot for testing wave and tidal devices. This is because of the many accustomed tidal currents around the archipelago and its affiliation to the Scottish grid. 

“Our acknowledged testing operations in Orkney has been a added important acquirements exercise in de-risking and convalescent the StreamCube to accommodate cost-efficient tidal energy band-aid to the market,” explained REAC’s Technical Director, Dr. Ing. Tobias Breitbach in an interview with Tidal Energy Today.

The after-effects from the trial will help REAC agree the all-encompassing ancestor before it progresses appear commercialization. REAC claim their device has a low cost, is easily carriageable and has little impact on the environment, amidst other benefits. 

Whilst the costs of ambience up a tidal power operation are high, once in place, operating costs are low. Research conducted in 2015 found that if you take into application construction, operation, and aliment costs over a lifetime, the levelized cost of tidal energy works out to be around $225/MW h. This is more big-ticket than other acceptable energy sources; however, as technology continues to improve, the costs of tidal energy will no doubt become more competitive.
