A 40 kWh GREENROCK salt water electricity storage system optimises the self-consumption of a residential complex in Wörgl, Austria. The storage unit is part of the Smart Cities funding campaign of the Climate and Energy Fund. This project promotes the expansion of public housing to encourage energy self-consumption. In addition to the connection to the district heating supply, which is fed by industrial waste heat, and the installation of a PV system on the roof of the building, the salt water electricity storage system complements the increasing relevance of ecological and sustainable building projects.
