Sweetch Energy raised €5.2M led by new investor Future Positive Capital, and co-led by existing investors Demeter and Go Capital.

Sweetch Energy, a Lorient, France-based producer of an advanced nanotechnology and eco-material science to harness osmotic energy, raised €5.2M ($6.3M).

The money was raised from new investor Future Positive Capital, and co-led by existing investors Demeter and Go Capital.

Other investors such as Dominique Gaillard, co-founder of Ardian, and Fabio Ferrari, founder of Symbio, one of Europe’s pioneers in the hydrogen industry, also participated. ADEME, the French environmental and energy management agency, provided additional funding as well.

Sweetch Energy, founded in 2016 by CEO Nicolas Heuzé and Lyderic Bocquet, CNRS researcher, director of the InstitutPierre-Gilles de Gennes (PSL University) and one of world’s foremost authorities on nanofluidics, is developing proprietary technology to harvest osmotic energy – an abundant and untapped source of renewable energy that is non intermittent and predictable.

Sweetch Energy’s proprietary system combines recent breakthroughs in nanofluidic sciences with low-cost eco-friendly materials to create next-generation membranes, coupled with specifically engineered electrodes and innovative cell designs. The technology yields unrivalled performances in the field and can harness osmotic energy with a level of cost-efficiency never achieved before, opening the door to large-scale deployment of osmotic energy as a competitive market solution.
