Abstract
The presentation focused on results obtained in the research project SafeBESS – Technology and building design for safe operation of battery energy storage systems. The project focuses on identifying hazards related to large battery systems installed in buildings, both related to the battery technology itself and also the battery room design. Through a thorough literature review and mapping of existing battery installations, it has been discovered a lack of standards related to risk assessment, requirements for battery installations and battery
rooms. Also, the project has performed fire testing of battery cells, modules and racks, where different extinguishing and suppression strategies were explored. This work also includes
wastewater chemical analysis to investigate toxicity levels of water used for suppressing or extinguishing battery fires. The main goal of the project is to establish required knowledge for developing national standards and regulations in Norway for design of battery rooms in buildings, ensuring safe operations of larger Li-ion battery systems.
