"Nankun", A massive floating power station powered by Ocean wave, all you need to know!
Can you think of living without ELECTRICITY ? Well, people lived right! Before! But... there is a big but. Without electricity means no internet, no internet?? Impossible!!
We all know that non-renewable energy is not going to last forever, don't you? Well non-renewable energy will barely last this century. Research and statistics says that we will be running out of non-renewable energy 100 years from now. This time could increase or decrease, it depends on our uses of this energy. But, what then? Well, here's renewable energy comes to save us with a great hug, feels so good inside right? Obviously, why not.
But, still this field is not well researched. We've plenty of resources available in nature but still we haven't discovered them yet and the few we've discovered we don't have proper technology to make them useful. Some of them are risky and hard to maintain. Today we're going to learn about a renewable energy generator that deals with one of the toughest but powerful renewable energy source available on the mother earth.

Talking about "NANKUN", an ocean wave based energy generator also called "Mobile Power bank". Not your kinda mobile power bank, an energy generator that floats on water and stores energy that it generates. You will get to know further how much energy it generates.
Nankun is designed by the "Guangzhou Energy Research Institute of Chinese Academy of Sciences". It's construction was undertaken/it's builder "Guangdong COSCO Shipping Heavy Industry, China". It's a triangular shaped floating power station that can produce 24,000 kWh of electricity per day. And it's massive!
So, How it works?
The Nankun has three sides, as it is in triangular shape. Each sides has five floating plates, makes a total of fifteen plates, which are driven upward and downward by the force of ocean wave. It's a three stage energy conversion, wave energy to hydraulic to electric energy. When plates are moved upward and downward it then causes the hydraulic rods to move back and forth, which produces hydraulic energy, and later hydraulic energy is being converted into electrical energy. And it's just not only produces green electric energy, but also it stores it as a power bank. That's why it is called a "mobile power bank"!

Nankun can be remotely controlled. So, it doesn't need any crew or to be controlled manually. It is now on operational trials of the coast of Zhuhai city of Guandong province. This amount of megawatt wave energy generation system shows China's great advancement in wave energy sector as well as technological advancement in renewable energy. Specially for the remote offshore island, Nankun could be the best choice ever until a new efficient offshore technology arrives. It's an example of being conscious about energy and environment as it is our greatest concern now.
China's development in clean energy is largely recognizable. According to "China Electricity Council" it's offshore wind power ranked top in 2021, worldwide. According to "China daily" China has reached 31.89 million kilowatts of offshore wind power, that's half of the worlds total offshore wind power/energy.

So, vessels like Nankun can be the savior of our future generation. We all know the effects of global warming besides the alarming decreasing rate of fossil fuels. So we need be more concern about this sector and invest more and more after renewable energy project specially in wave based energy generation, cause this sector has great potential but less researched. A great tribute to China for their technological advancement on renewable energy sector and specially praise for those people who were involved building the project "Nankun". That's it for "Nankun" today.
Some extra related information:
Wave energy: Using ocean waves to generate energy/renewable energy. This sector has a great potential with lot difficulties.
Difficulties of wave energy generations: Fluctuation of wave, turbulent wave, energy conversion efficiency of wave technology, tough sustainability with ocean storm. This industry faces with technological advancement and costly difficulties.
Wave energy applications: It's wider in range. Supporting marine observation, deep sea research and development of aquaculture, offshore energy supply, energy generation for the mass households, etc.
*Renewable energy is also called Green Energy, Clean Energy or Sustainable Energy.
*WEC stands for Wave Energy Converter.
