Tidal Turbine :How the world’s most powerful tidal turbine works

0

Tidal Turbine is new invention in the world. Scottish company Orbital Marine Power has launched the world’s most powerful floating tidal power plant – similar to the Orbital O2 spacecraft

What does a Tidal Turbine look like?

On April 22, 2021, Orbital Marine Power launched an O2 Floating Tidal Power Plant (TPP) with a total capacity of 2 MW. The 72 has a total weight of 60 tons, and the unit reaches a length of 64 meters.

O2 is located on a system in the Arkansas, north of Scotland. Where the structure will be connected to the European Marine Energy Center (EMEC) network. The design of the O2 is similar to that of a future space plane, but the technically very simple central element is a floating platform with two wings attached.

How do Tidal Turbine work?

Each has a capacity of 1 MW, equipped with two-blade turbines at the ends. And here’s how O2 works: The pontoon is anchored to the bottom by the front and rear anchors.
The turbines are lowered into the water at an angle of 45 degrees using hydraulic cylinders. Liquid-optimized blades rotate and continue to work during high tide. Electricity is transmitted to the grid through an underwater cable located behind the pontoon.
O2 capacity will be enough to power 1,000 households in the UK, with representatives of Orbital Marine Power promising to consume one kilowatt-hour of electricity “at a competitive level”.
In addition, the use of O2, a “green” power plant, can offset about 2,200 tons of carbon dioxide emissions per year.

What this means 02

The O2 launch comes in the context of UK industry and research incentives. Creating a floating tidal power plant could revolutionize the entire tidal energy sector.
Unlike the currently extensive coastal tidal power plants, floating “underwater wind turbines” do not require a huge dam.
Its construction takes a long time and involves a large financial investment.

Thus, theoretically, the cost of one kilowatt-hour of electricity generated by floating TPPs can be significantly cheaper than that of classical TPPs. Also, the maintenance of these national power plants can be done by small ships, which allows you to respond quickly in case of emergency.

The development of orbital marine power is in line with the UK’s ambitious plan to reduce carbon dioxide emissions and develop renewable energy sources. Companies and associations in the sector are hoping for government support to promote tidal power – from setting a 1 gigawatt target for “underwater wind turbines” by 2030 to introduce special mechanisms to support the industry in the form of contracts for differences.
