This week’s super cute illustration comes from our friend Gebelia – [http://www.gebe.it](http://www.gebe.it)

Swedish power company Vattenfall is testing a technology developed by SaltX that stores energy in salt, with a goal of proving whether the process would be useful for storage of renewable energy such as from wind and solar farms.

The process essentially mirrors how batteries work, except that instead of electricity, the system stores heat. SaltX says it has also patented a way of covering the quicklime with tiny particles — known as a nano-coating — to prevent it from lumping together after several heating and cooling cycles.

Energy stored chemically in this way can retain its heat for “a day, week or even a year without losing the energy over time”, unlike water, which cools rapidly by comparison.
