Kenal
Kenal is a system for the mechanical storage of energy by using flywheels. There is nothing to be invented; only different technologies to be fused and implemented properly. Some technological peculiarities, together with modern power electronics, have made possible to revitalize familiar physical concepts for getting to a final product. Ultimately, the low production cost makes Kenal quite competitive even with lead-acid batteries.
Kenal is available in several versions both for off-grid and smart-grid insertions. Wider application is in conjunction with solar panels for the self-sufficiency of sparse and not connectable users (i.e. rural buildings, telecommunication towers, surveillance facilities, etc.). A 2 MWh version is under specification for the off-grid electrification of rural villages in Equatorial Africa and Indian Sub-Continent. A special solution for the localised recovery of energy during braking of underground train has been started for being finalised during the 2016.
