Islands of Molokai & Isles of Scilly stores renewable energy as part of the experimental project to test battery storage systems.
The islands are often bereft of natural resources and have to depend on diesel generators for electricity. This could expel carbon dioxide in the environment, which are harmful to human health. Renewable sources such as wind and sun are useful for remote locations however the inability to store these energies for later use decreases its popularity.
According to a new agreement collaboration between the Hawaii Public Utilities Commission and Maui Electric, the renewable energy could now be captured and stored for later use. The Hawaiian island of Molokai with a population of under 10,000 people has some of the most costly electricity in the world at 36 cents per kWh. With the deal the Hawaii Public Utilities Commission purchased energy for the island of Molokai, a 22 year old pact, from a solar-plus-storage system at 50 percent lesser rates— 18 cents per kWh.
A 4.88 MW solar power plant will include a 3 MW, 15 MWh lithium ion battery storage system which will allow electricity to be stored for use during night. Also the residents’ roof top would have solar panels to tap solar power which could be stored for future use. More efficient home heating and electric cars are also part of the program.
A group called Smart Islands will now use Celtic Sea from the southwest tip of England, the Isles of Scilly to test battery storage systems that will bring the benefits of renewable energy.
The system is expected to bring various benefits such as clean environment, decrease in utility bills, minimal pollution, and others. They aim to develop a smart energy island with affordable and easy accessibility to renewable energy.
