Could the ocean be the future of energy storage?
There's no doubt that wind and solar energy would have taken over the world by now if it wasn't for the problem of intermittency. The power sources provide clean energy alternatives that are good for the environment.
This brings us to the question: what can be done about storage? There is the option of lithium-ion batteries, but it's a costly one. The lithium-ion levelized cost of storage is currently $131 to $232 MWh. Ouch!
So, researchers have begun looking into using the world's oceans as a potential energy storage solution. In this video, YouTuber Matt Ferrell explores the many technologies out there tackling this innovative goal and how they work.
Most of the solutions discussed in the clip are incredible from a technological perspective using the latest advancements to come up with options for storing energy inside the ocean. And they are as varied in terms of execution as possible.
They do, however, all share one thing in common: at the moment they are very expensive. Will the future see these innovations reduce their costs enough to be a viable energy storage option? This video answers this crucial question while bringing you in-depth illustrations of each of the different technologies and the ingenious ways in which they work.
