1. A hydrogen injection arrangement for injecting hydrogen into a combustion chamber of a combustor of a gas turbine system, the hydrogen injection arrangement comprising:
an outer conduit having an outlet in fluid communication with the combustion chamber, the outer conduit configured so that a mixture of fuel and air is passable into the combustion chamber via the outlet of the outer conduit, and
an inner hydrogen injection conduit positioned adjacent to the outer conduit, the outer conduit being positioned such that the outlet of the outer conduit is around an outer periphery of an outlet of the inner hydrogen injection conduit that is in fluid communication with the combustion chamber, the inner hydrogen injection conduit configured such that at least one jet of hydrogen is injectable into the combustion chamber via the outlet of the inner hydrogen injection conduit;
wherein the outlet of the inner hydrogen injection conduit is positioned to output the at least one jet of hydrogen toward a first wake region within the combustion chamber that is downstream of the outlet of the inner hydrogen injection conduit and upstream of a position within the combustion chamber at which the mixture of fuel and air output from the outlet of the outer conduit crosses a discharge region of the outlet of the inner hydrogen injection conduit, wherein the inner hydrogen injection conduit is positioned and configured such that a secondary wake region is formed by the at least one jet of hydrogen adjacent the first wake region or as it enters the first wake region.
