A method of pumping a heat transfer fluid in a thermal energy storage system (2) comprising a first thermal energy storage tank connected (200) to a second thermal energy storage tank (201) via a bi-directional flow member (202). The first and second thermal energy storage tanks (200, 201) are associated with a pressure vessel system (3) comprising a first and second pressure vessel (300, 301) each pressure vessel (300, 301) being partially fillable with an actuating liquid, wherein, the method for pumping comprises: displacing the actuating liquid from the first pressure vessel (300) to the second pressure vessel (301), 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. 一种在热能存储系统(2)中泵送传热流体的方法，该热能存储系统(2)包括经由双向流动构件(202)连接到第二热能存储罐(201)的第一热能存储罐(200)。第一热能存储罐(200)和第二热能存储罐(201)与压力容器系统(3)相联，压力容器系统(3)包括第一压力容器(300)和第二压力容器(301)，每个压力容器(300、301)部分地可填充有致动液体
