Scientific Publications

From its inception, ALACAES was committed to pursue high quality scientific work  in the development of its technologies. Therefore, close collaborations were initiated with renowned academic institutes across Switzerland.

Today, ALACAES collaborates closely with ETH Zurich, EPFL , SUPSI and PSI in order to support its innovative technological development with high quality research.

ALACAES is proud to be the main industrial partner for several nationwide, cross-institutional R&D projects funded by the SCCER, SNF and the Swiss Federal Office of Energy.
