    Abstract

    According to an example aspect of the present invention, there is provided a system comprising a cryogenic liquid storage tank (100), a first pressure tank (110) and a second pressure tank (120), both connected via leads to the storage tank (100), at least one ejector (130, 140), each of the at least one ejector (130, 140) being connected via leads to both pressure tanks (110, 120), and a controller, the controller being configured to admit cryogenic fluid from the storage tank (100) to the first pressure tank (110), to cause the cryogenic fluid to be heated to convert it into gas form, and to admit the fluid in gas form from the first pressure tank (110) through a first ejector (130, 140) from among the at least one ejector (130, 140), such that the fluid in gas form acts as a motive fluid to cause evacuation of the second pressure tank (120) as it passes through the first ejector (130, 140).
