Sweden - School relies on safety regarding power storage

Sweden - The city of Uppsala installed a safe and environmentally friendly GREENROCK saltwater power storage at the new Tiunda-school.

On the occasion of the grand opening of the school in late August 2018 the key representatives presented the new Tiunda-school. Politicians of the municipality of Uppsala, STUNS as a foundation for cooperation between schools, universities and public institutions and BlueSky Energy’s managing director Hansjörg Weisskopf were present. The leading representatives of the project talked at a press conference.

Arguments speaking for the use of saltwater energy storage

The city of Uppsala states in a press release the following arguments: Today lithium batteries are the standard when storing electricity. Lithium is expensive and its explosive properties can pose a risk to users. Lithium mining is not considered sustainable and has a negative impact for both people and the environment. Finding alternatives to lithium, especially for large scale energy storage, is one of the largest challenges to date for the transition to renewable energy sources. Salt water batteries are an environmentally friendly alternative to using a material with both environmental and public health consequences.

“It is thanks to the municipality’s high set climate goals and ambitions to be completely nontoxic in its school environments that we are now testing this battery, which its main content is saltwater, at Tiunda school. Uppsala welcomes the opportunity to share its experiences regarding smart climate and environmental solutions with other municipalities in Sweden and internationally” says Maria Gardfjell (Environmental Party) commissioner responsible for environmental and climate issues.
