Capital Nature provides seed funding to Chakratec, a new energy storage venture

Capital Nature is investing, and adding to its portfolio this young company that develops an energy storage and energy supply system through the use of flywheels.  Chakratec develops a  unique flywheel technology, and provides a competitive solution for energy storage through the use of batteries.

Chakratec’s system is based on materials and structure, backed by registered patents, that enable the production of flywheels at a significantly lower cost than existing flywheels today. This system meets the needs of an existing real market in the emerging field of utility-scale energy storage.

The first application for Chakratec’s solution will provide storage for energy that is generated during the day time in solar renewable energy fields, yet needs to be used in the evening when demand increases. Currently, solutions for storing energy are based on the use of batteries in areas that do not allow for energy storage through the use of hydroelectric systems.

Chakratec is led by three experienced entrepreneurs with previous success stories in the Israel high tech arena: Ilan Ben David, Nir Zohar and Dudi Pinko.

Capital Nature invests in new and existing ventures that are still in the R&D stage, as well as in applied academic research, in the Green Energy sector. The aim of Capital Nature is to bring to the market various innovations in renewable energy, energy efficiency, energy storage, smart grid, clean web, and alternative fuels. The company also operates a test and validation site for renewable energy technologies.  Capital Nature is backed by various leading companies in Israel, such as Rafael, Elbit, Ormat, Direct Insurance, Proseed, Consensus Business Group, Ben-Gurion University and more.
