Renewable energy storage is the next frontier.
Energy sourced from solar and wind is characterized with inherent variability. Standalone renewables are thus inefficient and, in many instances, do not provide sufficient return on investment (ROI) to make them economically viable. Thus, renewables necessitate the use of energy storage systems (ESSs) to manage power deployment and match supply to demand.
The rise of renewables has contributed to an explosion in the ESS market, with the sector being projected to be worth 13 billion USD worldwide by 2023. Currently, lithium-ion batteries (LIBs) comprise over 80% of ESSs.
The year 2040: earliest that LIB ESSs are projected to begin costing less than $20/kWh.
Current ESSs employ LIBs originally developed for roles in electric vehicles and consumer electronics. As a result, they sacrifice safety and cost-effectiveness for performance, and use liquid electrolytes comprised of volatile solvents and lithium salts that become unstable and prone to thermal runaway and even combustion at 70°C. Integrating LIBs into ESSs, then, requires external cooling, safety, and thermal monitoring systems that inflate costs and decrease scalability.
In developing System6, Natrion decided to completely rethink how ESS batteries are made. Focusing on intrinsic safety and cost-efficiency, Natrion created a ceramic solid-electrolyte that is stable beyond 1400°C and implemented it in a significantly cheaper sodium-ion architecture. Without the need for external cooling and monitoring systems, System6 is able to achieve unparalleled safety, efficiency, and cost-effectiveness with scale.
The world's first battery optimized for renewable energy storage.
System6's potential impact is staggering. Having already attained a price $91/kWh, the technology is poised to achieve $20/kWh by 2027. Natrion is working toward a 2023 launch of a 16kWh System6 product for residential rooftop and community solar in New York's Southern Tier region, and hopes to release a grid-scale ESS product in 2028.
