Abstract: A direct fuel injection system (206) is shown for injecting hydrogen fuel into a gas turbine combustor, the fuel injection system comprising a plurality of fuel injector blocks (1202). Each fuel injector block includes one or more air admission ducts (1603) for receiving air from a diffuser and an air outlet for delivering air into a mixing zone for combustion with fuel. Each fuel injector block also includes a fuel admission duct or aperture having a fuel inlet for receiving fuel (F) from a manifold, and a fuel outlet for delivering fuel into the mixing zone.
