Many modern steel plants already use electric arc furnaces originally developed for aluminum manufacture in the 30s and 40s. There is no inherent reason not to collocate steel plants with plentiful renewable energy. As energy is one of the primary input costs to steel manufacture, it should be practical to develop “peaker” plants which take advantage of the midday energy cost dips due to solar.
