Reworking the Flywheel for Better Energy
Energy is all around us - it can be harvested from sources such as wind, sun and moving water - but it''s still difficult to store effectively. Working
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
Working under the supervision of Pierre Mertiny, researchers are chipping away at the challenges and high costs of energy storage. One possibility is the new use of an old technology: the flywheel. You know, almost intuitively, how the mechanical energy storage system called a flywheel works.

Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
High-strength steel flywheels have a high energy density (volume-based energy) due to their high mass density. Furthermore, they are superior to composite ones regarding thermal conductivity and design data availability, such as SN curves and fracture toughness.
One possibility is the new use of an old technology: the flywheel. You know, almost intuitively, how the mechanical energy storage system called a flywheel works. Think of a foot-operated sewing machine or a spinning top. Both collect and store kinetic energy in the flywheel, and release it when needed, typically over a short time.
