SaltX Hack #2: The off-grid turn-on

Hack energy storage for everyone, utilizing SaltX Technology.

Background
There are many places around the world where electricity grids do not yet exist, in other words these places are “off-grid”. Therefore there is a great need for off-grid solutions, especially in developing regions like India and Africa. A small and simple product such as an off-grid fridge or water heater can ease the daily life for families in rural areas. The technology available today are often not healthy, environmental friendly and expensive.

Challenge
Change the everyday life for people in development countries, and come up with a cost effective off-grid solution using renewable energy.

You should make a customer-oriented business case. Think globally and create a simple and robust solution. The biggest challenge with this is to create an innovative concept that is it affordable for the billions of people living in these areas.

Who are you?
You might be an entrepreneur, a creative, a business student or an engineer. We need all competences to solve this challenge.

The technology
The key in the technology of SaltX is that the salt can be charged and discharged thousands of times without losing its characteristics. The technology works very much like a battery. A simple way to describe it: salt water is boiled which leads to the salt and water being separated from each other. Dry salt is what remains in the chamber. The boiling water ends up in a second and separate vessel. A valve is closed and keeps the two from each other, the boiling water condenses.

When opening the valve, the water then reunites with the salt, a chemical reaction takes place, and heat energy is released. The vessel where the water has been during the separation gets very cold due to an equalization of the energy balance. The charge and recharge process of the salt takes place in a closed vacuum system. Therefore, it can be repeated almost unlimited number of times. The salt can be heated/charged with any energy, from renewable energy to waste heat from an engine or a gas burner.
