Alphabet's X division harbors a multitude of experimental ideas. Project Malta was one of them. Malta utilizes easily obtainable abundant materials including salt, anti-freeze and steel to store power at grid scale.
Malta uses the laws of thermodynamics grid-scale energy storage that relies on molten salt to store energy be they renewable or fossil, as heat in molten salt and as cold in low-temperature anti-freeze until it's needed. The future is bright for Malta as renewable energy, the kind that needs storage, is in the rise.
What is more, Malta is working on a pilot plant, backed by $26 million from its first funding round, with backers like Jeff Bezos, Bill Gates and Michael Bloomberg.
Malta’s solution is to store electricity as heat in high temperature molten salt and cold in a low temperature liquid for days, or even weeks, until it’s needed. The key insight behind Malta is that electricity can be stored as heat in high temperature molten salt and cold in a low temperature liquid for days, or even weeks, until it’s needed. Malta uses cheap, common materials — like salt, steel, anti-freeze, and air. Using molten salt to manage energy is not a novel idea. We today have a quite a few projects using such technology. But new products through the same idea, benefits all of us.
