As the energy demand has become insatiable with the ever-growing population and its needs, renewable energy has become the primary source of interest, since it is produced by a source that does not run out. The biggest challenge is storing renewable energy until it is needed. Enter Green Power Island. Solar, wind, hydro, geothermal, and biomass are all renewable energy sources, but some of them are now being stored at Green Power Island. Does that not sound familiar? It’s not the end of the world, as long as you know there is a reason why some people call the island the “blue battery” over the sea.
Why proper storage of renewable energy matters
Think about it. Energy consumption is at its peak during specific times of the day. Energy sources such as wind and solar fluctuate constantly, and they might not produce the required energy needed during peak consumption times. That is why the biggest challenge in transitioning to a renewable energy-based system is aligning energy production with the demand for energy consumption.
The ideal solution is to store excess solar and wind power energy on a large scale, ensuring the power supply’s efficiency, stability, and security. Unfortunately, this ideal solution is easier said than done for the world’s many low-lying, flat coastal regions. They are ideally located for wind farms, both on land and at sea, but they lack the necessary systems to store electricity on a large scale. That is, until the revolutionary concept of Green Power Island was born.
The visionaries behind Green Power Island
The project’s visionaries are Gottlieb Paludan Architects and the Risø National Laboratory for Sustainable Energy under the Technical University of Denmark, with support from Danish and international advisors. They were inspired by methods practiced by mountainous countries such as Norway. Their demand for energy consumption at peak times is met by pumping large volumes of water into high-altitude reservoirs and then leading the water back down through turbines to generate electricity. They refer to this method as hydropower.
Artificial energy islands are the way of the future
Thus, the creation of Green Power Island began. The project proposes that artificial energy islands will be manufactured to store renewable energy whenever the total energy generated exceeds the actual demand. The electricity is initially produced on the island by wind turbines or solar-power arrays that float in the reservoir lake. The islands have deep gorges, so when energy is in excess, seawater is pumped out of the gorges. When energy consumption demand rises, seawater is guided back into the gorges through turbines, regenerating 75% of the energy. Hence, people refer to Green Power Island as a blue battery.
The project can be used for multiple practices
As amazing as Green Power Island already sounds, there’s even more good news behind the project. The artificial islands’ gorges are never completely emptied, which means they can be used for other practices such as aquaculture. Mussels and algae can be raised, or algae can be cultivated for biomass provisions or animal fodder.
The energy storage can also be used in conjunction with a wide range of synergistic motives. This, of course, depends on the size and location of the islands. Accordingly, artificial islands such as Green Power Island serve as “energy hubs” in larger, combined energy systems.
This innovative project will definitely act as an incentive for a full-blown switch to a green energy standard. Artificial islands, such as Green Power Island, offer a creative and international approach to large-scale energy storage, an element often seen as the “missing link” in transitioning to a fossil-free society. We cannot wait to see how this project changes the future.
