Teraloop's innovative flywheel Solution provides efficient energy storage for EV charging whilst avoiding high infrastructure installation costs.

Energy storage can help to avoid the need for expensive infrastructure upgrades needed to charge electric vehicles. Lithium batteries are a prime candidate as a solution in this market, however they are limited in their cycling ability, and will reach end of life rapidly when used for this purpose. Teraloop's flywheel technology (a mechanical structure used to store rotational energy) complements existing flexibility solutions to manage power and energy. Flywheels have demonstrated advantages such as high energy efficiency, high durability and high power density, making them ideal for applications requiring heavy cycling. Teraloop goes beyond the state of the art with its novel topology, enabling higher scalability to MW scale with a single device, and 5-7 times higher energy density. Teraloop's flywheel technology is ideally designed for applications such as electric vehicle ultra-fast charging, as well as micro-grid retrofitting. It further complements existing battery technologies, extending their lifetime and their sustainability.
