PHENOGY in the Press: Resilient Energy for Armed Forces

Sodium-ion battery storage makes energy supply more resilient: robust in operation and at extreme temperatures, independent of vulnerable supply chains. The military benefits too: in our contribution to the "Future of Defence" supplement, we explain why the technology is ready for the field. The supplement was published in September 2026 in the Frankfurter Allgemeine Zeitung, one of Germany's leading national newspapers (in German).
