Apparatus and method for fuelling

An apparatus for fuelling comprising:

• a plurality of vessels for containing a fuel gas, each vessel of the plurality of vessels being selectively fluidly connectable to at least one receiving vessel;
• a control means configured to selectively divide the plurality of vessels into a plurality of banks by selecting between allocating one vessel of the plurality of vessels and more than one vessel of the plurality of vessels in each of the plurality of banks;
• at least one first restriction arranged to provide a first gas flow rate for gas exiting the plurality of vessels and at least one second restriction arranged to provide a second gas flow rate for gas entering the plurality of vessels;
• wherein the control means is further configured to sequentially fluidly connect the plurality of banks to the at least one receiving vessel such that when one of the plurality of banks is fluidly connected to the at least one receiving vessel the one or more of the plurality of vessels within that bank are fluidly connected to the at least one receiving vessel but are fluidly isolated from the one or more of the plurality of vessels of the remaining ones of the plurality of banks;
• and
• wherein the second gas flow rate is different to the first gas flow rate.
