Abstract [en]

To decelerate climate change and global warming a transition from fossil fuels to renewable energy is necessary. However, integrating a high share of renewable energy sources in a power system introduces challenges in balancing load with generation, and to maintain system reliability. As a result, the interests of energy storage technologies have increased. Northvolt plans to build the largest battery factory in Europe, located in Skellefteå (Sweden), which will produce lithium-ion batteries based on a 100 % renewable energy supply. An overall energy mapping was carried out to study how and where the energy is used in the battery manufacturing process of Northvolt Ett. Focus of this study was on the preparation of active cathode material due to it’s an energy intensive process step and had the most data available. The energy mapping aimed to enable the procedure of locating heat recovery proposals for optimal use of energy in the factory. Two strategies for heat recovery were performed, one theoretical based on Pinch Analysis (PA) and a practical developed by a dialogue with Alfa Laval. The result of this study is increased knowledge of the energy use in the battery manufacturing process, an estimation of potential heat recovery and proposal for a method for further work to identify maximum energy recovery.
