scalum® is our Alkaline Water Electrolysis (AWE) module. It marks a significant milestone in our unique development path. We combine about 300 high-efficiency cells into one powerful unit with a system capacity of 20 MW. Designed as a standardized modular solution that can be easily interconnected and scaled up unit by unit. With scalum® we can realize and match highest demands: The prefabricated AWE units can be easily transported, installed and interconnected to obtain the desired plant capacity, up to several hundred megawatts or even gigawatts as a cost efficient, highly modularized solution for large-scale green hydrogen production. Shaping a new era of clean energy with green hydrogen at industrial scale.
