vacuum thermal energy storage and insulation technology
Vacuum super insulation (VSI) allows highly-efficient heat storage due to exceptionally low thermal conductivities of insulating storage envelope. Using expanded perlite powder, VSI has been applied for many years to store liquefied gases at −200°C. Recently, the technology has been transferred to thermal storages up to 160°C.

flywheel vacuum energy storage principle video
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
