WHAT IF THE FUTURE OF ENERGY STORAGE ISN'T ABOUT FINDING ONE WINNING BATTERY? // For years, the conversation has focused on a single question: What comes after lithium-ion? At ees - electrical energy storage 2026, Andreas Pesl, Head of Energy Storage Systems at EDAG Group, offered a different perspective during his presentation on sodium-ion technology. His key message: the real question is not whether sodium-ion will replace lithium-ion. It's where it creates the most value. Sodium is widely available, reduces dependence on critical raw materials, and offers advantages in safety and sustainability. But it also comes with limitations, particularly lower energy density. That means sodium-ion is unlikely to become the answer for every application. And maybe that's exactly the point. The future of energy storage will not be decided by a single battery chemistry. It will depend on selecting the right technology for the right use case and designing systems around its strengths. For stationary energy storage, sodium-ion is increasingly emerging as a technology worth watching. If you're attending ees Europe, visit our team at Hall C2, Booth 254 and continue the conversation.
