Abstract
A method of pumping a heat transfer fluid in a thermal energy storage system comprising a first thermal energy storage tank connected to a second thermal energy storage tank via a bi-directional flow member. The first and second thermal energy storage tanks are associated with a pressure vessel system comprising a first and second pressure vessel each pressure vessel being partially fillable with an actuating liquid, wherein, the method for pumping comprises: displacing the actuating liquid from the first pressure vessel to the second pressure vessel, thereby creating a pressure difference in the first thermal energy storage tank with respect to the second thermal energy storage tank, and therein displacing the heat transfer fluid via the bi-directional flow member.
