BASF is close to completing the construction of a demonstration steam cracker furnace in Ludwigshafen, Germany, for making ethylene with renewable electricity rather than fossil fuel as a heat source. The approach promises to cut the carbon footprint of ethylene production by 90%. Construction of the demo plant has taken almost a year. It features nine transformers, each of which can convert several thousand amps of current into heat. The project is being developed jointly by BASF, Linde, and Sabic.
