We are continually evaluating and testing technologies that can further our goal in creating a cleaner, more efficient and sustainable planet.”įounded in 2012 as a spin-off of Stanford University research, Natron Energy – formerly Alveo Energy – is developing a new battery technology for a wide variety of energy storage applications. Laurent Torcheux, Head of the batteries group at EDF R&D, said: “We’re intrigued by the potential of Natron Energy’s new battery cell technology for grid storage applications. Prussian Blue dye, commonly used in blueprints, stores and releases energy in the form of sodium ions. The testing and evaluation of Natron’s patented technology, based on Prussian Blue analogue electrodes and a sodium-ion electrolyte, will be conducted at EDF’s battery test labs in France.

In addition, the Natron sodium-ion battery technology shows excellent safety and sustainability features that are not dependent on rare earth elements, critical mining processes, or questionable supply chain implications.Natron Energy has entered into an evaluation agreement with Electricite De France (EDF) on the potential use of its technology for stationary storage applications in support of the growing use of grid-scale renewables. Natron's sodium-ion battery cells possess performance characteristics between lithium-ion batteries and supercapacitors in terms of power capability, energy density, and cycle life. Both single cells and battery modules (32 cells in series) are evaluated and compared with other commercial batteries. The present study assesses the first commercial Prussian blue-based sodium-ion pluggable battery module developed and refined in a joint design effort between Natron Energy and ABB, offering insights into the competitiveness and maturity of sodium-ion technologies. Among different sodium-ion cell chemistries, Prussian blue analogues (PBA) have advantages of excellent electrochemical stability, low cost, and high-rate capability, thanks to their open-framework lattice suitable for sodium-ion intercalation. Novel sodium-ion battery technologies have emerged in recent years and are considered as potential alternatives to lithium-ion batteries for large-scale stationary storage applications.
