Solstice energy storage

We're revolutionizing the storage of solar energy! Every night the sun sets and 60 % of the time the wind is not blowing. For this reason, no electricity grid can rely fully on only these two renewables. Today this shortcoming is backed up by a planned energy source, usually fossil coal, oil or natural gas. The natural alternative is energy grid storage, which today costs 4000 SEK/kWh limiting its adoption. Solstice utilizes a highly efficient solar collector in concert with an innovative transfer medium allowing the efficient use of low cost thermal storage in sand. This lowers the cost of storage with more than 89 % making energy storage competitive. Join us in our journey to enable the further use of renewables and making our electricity grids fully renewable with affordable energy storage.
