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.
