News<\/a> Industry news<\/span><\/a><\/p>\n<\/div> The federal-state working group has recently published the guidance paper on handling lithium-ion batteries (LIB) in accordance with the Ordinance on Installations for the Handling of Substances Hazardous to Water (AwSV). Here are the most important findings and the implications of the paper for the storage industry, particularly for lithium-ion batteries.<\/p>\n<\/div><\/div><\/div> BVES<\/p>\n<\/div><\/div><\/div> 05.08.2024<\/p>\n<\/div><\/div><\/div> The AwSV, the Ordinance on Installations for the Handling of Substances Hazardous to Water (wgS), has a broad scope of application. It aims to protect bodies of water from the harmful effects of these substances. This applies to systems such as heating oil consumer systems as well as slurry, liquid manure and silage seepage systems. Lithium-ion batteries are a new addition and are now also regulated by the AwSV.<\/p>\n The AwSV specifies requirements for the handling of ready-made, stationary battery cells that use lithium in their cell chemistry (lithium-ion batteries, LIB), as well as for the battery modules and sets assembled from them. This includes:<\/p>\n However, the AwSV does not include lithium-ion batteries that are used in mobile or non-fixed applications, such as in electric vehicles, for the transportation of goods or in the private sector. There is also a de minimis limit of 0.22 cubic meters for liquid substances and 200 kg for solid substances hazardous to water (Section 1 (3) AwSV). Installations below this limit are not subject to the AwSV.<\/p>\n The AwSV paper has a key role to play in the approval of Li-ion battery systems. It provides information on technical requirements and obligations for water protection that operators of such systems must comply with. The regulation is aimed in particular at companies that operate systems for handling substances hazardous to water, such as systems for storing, treating or filling these substances. Whether lithium-ion batteries actually involve the handling of substances hazardous to water was a recurring point of discussion during the preparation of the information sheet. After all, batteries have casings that must not be opened during their entire service life. From the point of view of the AwSV, the main focus for stationary batteries is now on leakage and extinguishing water retention.<\/p>\n The BVES participated intensively in the consultation on the draft, with a detailed technical statement. The association argues that batteries do not handle substances hazardous to water (wgS), as is the case with slurry or oil plants, as battery modules must not be opened during their service life. Nevertheless, the BVES gives top priority to the safety of plant operation and environmental protection. Clearly, concerns about water protection in batteries are to be taken seriously and regulated. BVES has provided its expertise on the current state of the art as well as a range of existing regulations and proven safety measures to develop a solution that reconciles water protection standards with sustainable and economical battery operation. Batteries are critical to the transformation to a sustainable energy system and a green industry. Without energy storage, there will be no energy transition. Batteries with different cell chemistries are high-tech products that are already protected by proven norms and safety standards and will have to provide even stricter proof of safe production, transportation and use in the future. The EU Battery Regulation (BattVO), recently enacted, regulates the entire value chain of batteries, from production to recycling, and also addresses safety issues in a new and mandatory way. Fire protection is a central issue when using batteries. Modern battery systems are designed in such a way that the source of a fire is very limited and cannot spread to neighboring modules or containers. The defective module should be able to react without external influence, whereby the escape of hazardous substances into the ground is excluded. The EU BattVO (2023\/1542) now brings the so-called propagation test for stationary storage systems into play at a central point. This test, which has been in use for 15 years, has proven its worth in checking how far a fault propagates within the battery system and whether the battery housing remains intact. The possible results of this test range from no propagation, to propagation only within a battery module but not between battery modules, to complete propagation throughout the battery system. Many battery systems are not designed to be extinguished with water. It is regulated and recommended in fire protection reports and coordinated with the local fire department. In this case, the AwSV information paper also stipulates that extinguishing water retention can be omitted. The BVES fire protection guidelines are now being updated, and the new version will also contain recommendations with respect to the AwSV guidance document.<\/p>\n Water protection is a very serious issue for the storage industry. Safety standards have always been very high, especially in Germany, and will be further increased. This is another reason why there has never been an accident involving a large battery in operation. It is important that the water protection requirements are technically well-founded and easy to implement so as not to hinder the growth of the storage sector. The energy transition needs energy storage systems, and battery storage systems are a vital part of the storage landscape. This requires uncomplicated communication and processes in approval procedures. <\/p>\n<\/div><\/div><\/div>AwSV gui\u00addance paper: Impli\u00adca\u00adti\u00adons for lithium-ion bat\u00adte\u00adries<\/h1>\n<\/div>
