Project Details


Cement production is one of the most energy consuming and CO2 emitting industries. A vision within this industry is to enable such productions with zero CO2 emissions by 2030. This necessitates efficiency improvements at all levels, from material types and usage to processes and material handling. This project will develop an entirely new efficient drive technology for cement handling systems based on the concept of electro-hydraulic power regeneration networks. The proposed technology utilizes variable-speed motor/pump units as its core and these units share multiple hydraulic lines as well as an electric DC-bus. Combined with multi-objective controls, the technology allows to distribute power between different parts of the system, while enabling individual actuation of these parts. The developed cement handling systems will be highly efficient, highly scalable, durable and commercially feasible compared to state-of-the-art. The proposed technology is developed through thorough understanding of physical features, innovative control methods, cement handling applications and commercial aspects. The goal is a green technology that improves average efficiencies with at least 50% and is scalable up to 250 [kW] output power.
