Abstract

A gaseous fuel supply system (100) for a clean combustion engine (10) configured to receive gaseous fuel at a changeable demanded injection pressure being above a predetermined minimum required injection pressure and below a predetermined maximum required injection pressure: The supply system (100) comprises a control unit (17) configured to: control supply of pressurized gaseous fuel from a first gaseous fuel tank arrangement (105) to the clean combustion engine (10) using a second supply line (122), and control a compressor (150) such that the gaseous fuel in a buffer tank (170) is pressurized to at least the current demanded injection pressure, in response to that the pressure of the gaseous fuel in the first gaseous fuel tank arrangement (105) is below the current demanded injection pressure or a predetermined first threshold value; and to subsequently, in response to a sudden increase in the demanded injection pressure, control supply of pressurized gaseous fuel from a second gaseous fuel tank arrangement (110) to the buffer tank (170) using the third supply line (124).
