Powerfiller introduces groundbreaking gas upgrading and energy storage technology. The Smart to Gas Activator enhances the volume of 100% fuel gas by up to 25%. More economically available gases are incorporated to increase the volume and create "activated gas." The activated gas has a higher calorific value compared to the original gas. The activator significantly increases the calorific value of all combustion gases with minimal capital investment. Powerfiller's solution enables sustainable, long-term storage of excess green energy. The technology enhances the efficiency of fuel gases such as natural gas, propane, and biogas. The increased calorific value of gases leads to improved economic efficiency and flexible temporal consumption of stored electricity. Powerfiller's technology offers modularity and high mobility, serving as an alternative to "Power to Gas" technology. The design is scalable and modular, allowing phased construction and expansion from small-scale systems to large-scale projects.
