1. A method of continuously performing at least one heat-consuming chemical process of a chemical site obtaining hydrogen, the method comprising:
drawing electrical energy required for at least one heat-consuming process from an external power grid and from at least one local power source,
feeding the at least one local power source from at least one local energy carrier network, to an extent of at least 50% of annual energy demand of the at least one local power source,
feeding said at least one local power source with hydrogen that comes directly from the at least one heat-consuming process, to an extent of not more than 50% of annual energy demand of the at least one local power source,
storing hydrogen from the at least one heat-consuming process as an energy carrier in the at least one local energy carrier network, and
feeding a local hydrogen network with hydrogen from at least one further chemical process;
wherein the at least one heat-consuming process is electrically heated, the maximum temperature in a reaction zone of the at least one heat-consuming process is higher than 500° C., and at least 50% of hydrogen of the at least one heat-consuming process is continuously processed further via a product conduit in downstream processes and via a conduit supplied to the local hydrogen network, and
wherein a total capacity of the local hydrogen network is at least 5 GWh.
