Let‘s talk about energy storage with Dr. Matthias Schulz

We asked our department head for stationary energy storage Dr. Matthias Schulz: what are the two biggest trends in energy storage today? And which three challenges must we overcome to reach our energy transition goals? Do you agree with his observations? Which trends and challenges would you add? Let us know in the comments!
Let's continue the conversation at the ees - electrical energy storage from June 14-16 at Messe München! Visit us at 𝗕𝗼𝗼𝘁𝗵 𝟯𝟳𝟵 in 𝗛𝗮𝗹𝗹 𝗕𝟭 and learn more about our ceramic battery technology for stationary energy storage as well as our solutions for the hydrogen market ramp-up.

Hello Mathias, I saw some of your earlier videos about the sodium Nickel batteries. Do you have some information about their performance such as round trip efficiency, and standby losses etc.? Where can I find this information? I am interested to compare it with a Zinc - Chlorine Hydrate storage system. Thanks.

Hello Greg, sorry it took a while to respond ;-) RTE or standby losses strongly depend on battery module and system design as well as on external temperatures and the utilization itself. So, there is no single number that I can give you. Since our technology runs at 270 °C a good thermal insulation is mandatory and can minimize the losses. This is in contrast to Li-Ion BESS. They usually need a chiller or air condition to guarantee the well feeling temperature for the cells. Otherwise, they lose performance and lifetime or even run into safety issues. This cooling definitely lowers the RTE! And this aspect, by the way, is verry often not mentioned. Published data are hard to find. Please check this page: ITP’s Battery Test Centre | ITP Renewables (www.itpau.com.au). The Australian colleagues had several batteries in real live test a sodium nickel chloride battery (from FIAMM) was under testing, too. Looking at these date sodium nickel chloride is on the same level as Li-Ion. Best regards, Matthias
