Store heat to fight global warming?
We are creating a new method for storing energy in the form of heat during the summer. During the winter, the heat is used to heat water and indoor air.

Sand battery as part of a plan for crisis management?
We are looking at the possibility of installing sand batteries in connection with schools and other public buildings. Sand batteries would not only save electricity through more efficient heating, but also serve as an important part of emergency preparedness.

Store heat to fight global warming?
We are creating a new method for storing energy in the form of heat during the summer. During the winter, the heat is used to heat water and indoor air.
Renewable energy is one of the UN's global goals. In the same spirit as the sand battery's objective, number seven is to "ensure access to economically affordable, reliable, sustainable and modern energy for all"
A large percentage of our greenhouse gas emissions come from the way we extract, convert and use fossil energy, not least for heating. For a normal Swedish villa, approx. 70% of the energy consumption is estimated to be used for heating hot water and indoor air.
Renewable energy solutions are becoming cheaper, more reliable and more efficient every day. The sand battery can be an important contribution to this development as it offers a solution to one of energy production's biggest challenges, namely a source of even energy supply all year round.
Solar energy stored in sand can keep the heat for months, which means that heat generated during the summer can be used to heat houses and water during the winter months. The sand battery is right on time: green, clean energy that is stored in sand, which is a cheap raw material with a low climate impact.
