Abstract: A gas turbine process includes supplying a fuel to a gas turbine, combusting the fuel in the gas turbine with a hot gas path temperature reaching at least 1100° C. during operation of the gas turbine, and supplying an inhibition composition including at least one yttrium-containing inorganic compound to interact with the vanadium and inhibit vanadium hot corrosion in the gas turbine caused by vanadium as a fuel impurity in the fuel. A process includes supplying an inhibition composition including at least one yttrium-containing inorganic compound to a hot gas path or a combustor of a gas turbine. A fuel composition includes a fuel including at least one fuel impurity including vanadium and an inhibition composition including at least one yttrium-containing compound. An atomic ratio of yttrium to vanadium in the fuel composition is in a range of 1 to 1.5.
