Joint project: ChemEFlex - feasibility of load flexibilization of electrochemical processes in industry


The ChemEFlex research project aims to identify and economically evaluate flexibility potentials of electrochemical processes in the chemical industry. One of the goals is to demonstrate the technical and economic feasibility of a fluctuating mode of operation in such processes. The process- and reaction-related requirements as well as the economic efficiency of an implementation under different market scenarios are examined. The research project focuses on the real technically and economically feasible load management potentials associated with chlor-alkali electrolysis.

Modelling and evaluation of chlor-alkali electrolysis and other processes

The following four chairs at TU Berlin participate in this project: Energy Engineering and Environmental Protection (ETUS) (project management), Process Dynamics and Operations (dbta), Chemical Engineering / Electrocatalysis - Materials (ECEMS), and Chemical Engineering / Reaction Engineering of Heterogenic Systems (TC-MR). They are responsible for essential scientific analyses of chlor-alkali electrolysis (CAE) and alternative electrochemical processes. For CAE, an optimized flexible process control under the general conditions of the electricity market and technical restrictions is developed. For the alternative processes, the technical feasibility of a flexible operating mode is investigated. The technical flexibility potentials identified are evaluated from a business and macroeconomic point of view and their potential future contribution to energy system transformation is determined.


The ChemEFlex research project is funded by the Federal Ministry of Economic Affairs and Energy within the framework of the 6th Energy Research Programme.
