The latest generation of the TorqStor can be integrated into mechanical, electrical or an advanced hydraulic transmission system, providing a modular energy storage solution that scales seamlessly from 250KJ to 4MJ to support a wide variety of applications without the cost of multiple variants. Artemis is collaborating with rail technology expert Bombardier Transportation and Ricardo on the Innovate UK-funded DDflyTrain project.

TorqStor differentiates itself from other flywheel designs with its unique permanent vacuum, saving both cost and weight. This is made possible by its advanced magnetic gear system that enables the transmission of torque across a vacuum without the limitation of rotating seals or necessity for vacuum pumps.
