A scalable and sustainable grid-scale energy storage system utilising 3rd generation flywheel technology for effective integration of renewable energy.

Project description

New tools to meet energy transition needs

Growth does not need to cause environmental pollution. There is a way to store energy that can meet the needs of the population, and provides a zero-waste solution. The EU-funded Teraloop EES project has the solution: a grid-scale energy storage system that can sustainably service niche markets difficult to address for current technologies. Drawing upon proven technologies (flywheel energy storage, magnetic levitation and brushless motors), this highly scalable, kinetic energy storage system can innovatively configure for grid-scaled storage with minimal visual and environmental footprint. For instance, its rotor is hubless and made of lightweight, strong and recyclable carbon fibre composites, and it allows for five times higher energy storage capacity.


Electrical energy storage (EES) is a fundamental enabler to the deployment of renewable energy and provides cost-savings in other markets. The market is projected to grow from 1.1 GW in 2016 to 21.6 GW in 2025. Pumped hydroelectric storage (PHS) accounts for 98% of global energy storage, however they are geographically limited, environmentally impactful and require huge upfront costs. Other state-of-the-art solutions available in the market i.e. batteries for EES cannot scale-up to meet the demands on the electrical grids and networks. This results in an underutilisation or ineffective use of renewable energy sources.
Teraloop has created a highly scalable, kinetic energy storage system, which draws upon proven technologies (flywheel energy storage, magnetic levitation and brushless motors.), innovatively configured for grid-scale storage with minimal visual and environmental footprint. The scalability of the system makes it suitable for a range of applications such as voltage support, frequency regulation, peak shaving, T&D upgrade deferral & congestion relief, load following and arbitrage.
