A method of providing fuel suitable for the generation of electrical power, which comprises: (i) subjecting a heavy hydrocarbon feedstock to delayed coking to yield coke and liquid hydrocarbon output; (ii) gasifying coke, produced in step (i), to yield synthesis gas; (iii) removing hydrogen sulfide from synthesis gas produced in step (ii); (iv) recovering hydrogen from synthesis gas subjected to the hydrogen-sulfide-removal of step (iii); (v) hydrotreating liquid hydrocarbon output produced in step (i), a substantial amount of the hydrogen used in said hydrotreatment being hydrogen recovered in step (iv); and (vi) transporting liquid hydrocarbon output subjected to step (v), and synthesis gas subjected to step (iii) and/or both steps (iii) and (iv), for use as fuel in a combustion turbine adapted for the generation of electrical power; and further a method of generating electrical power, and systems for producing said fuel and generating electrical power. L'invention concerne un procédé pour l'élaboration de combustibles adaptés à la production d'énergie électrique selon les étapes suivantes: (i) cokéfaction différée d'une charge d'hydrocarbure lourd pour obtenir du coke et un hydrocarbure liquide; (ii) gazéification du coke issu de l'étape (i) pour obtenir un gaz de synthèse; (iii) élimination du sulfure d'hydrogène dans le gaz de synthèse issu de l'étape (ii); (iv) récupération de l'hydrogène dans le gaz de synthèse débarrassé du sulfure d'hydrogène selon l'étape (iii); (v) hydrotraitement de l'hydrocarbure liquide issu de l'étape (i), une quantité substantielle de l'hydrogène utilisé pour l'hydrotraitement étant l'hydrogène récupéré en (iv); et (vi) transport de l'hydrocarbure utile traité en (v) et du gaz de synthèse traité en (iii) et/ou à la fois en (iii) et en (iv), pour une utilisation sous forme de combustible dans une turbine à gaz adaptée à la production d'énergie électrique. On décrit un procédé relatif à la production d'énergie électrique et des systèmes relatifs à la production de ce combustible et de l'énergie électrique.
