The present application relates to a process for cracking a hydrocarbon feedstock, using to the largest extent electrically powered equipment where the power is obtained from renewable sources or low-carbon sources. In particular, it relates to a furnace for steam cracking a hydrocarbon feedstock, wherein the furnace comprises one or more tubes for transporting the hydrocarbon feedstock and dilution steam; and an electrically heated infrared emitter for transferring heat to the tubes. It also relates to a process for steam cracking a hydrocarbon feedstock using infrared radiation.
