February 23, 2019 PATENT AND KNOWHOW LICENSE AGREEMENT Patent and Knowhow License Agreement (hereinafter also referred to as “Agreement”) between Heindl Energy GmbH, a German limited liability company (GmbH) with its registered domicile at Am...Patent and Knowhow License Agreement • March 25th, 2019 • Gravity Storage Inc. • New York
Preamble WHEREAS the Licensor is the developer of the concept of Gravity Storage, a system to store large volume of electricity based on the hydraulic lifting of a very huge rock mass using water pumps. The rock mass acquires potential energy and can release this energy when the water that is under pressure is discharged back through a turbine. The decisive variable with such energy storage lies in the storage capacity, which will reach its best reasonable business case at a size between 1 and 10 GWh capacity which increases with the fourth power of the radius, r4. The construction costs however only increase with the square of the radius, r2. This means that the construction costs increase substantially more slowly than the storage capacity. Thus, very low costs per kilowatt hour of storage capacity are possible. WHEREAS the Licensor owns the intellectual property rights with respect to the concept of Gravity Storage, including various registered patents and patent applications as
