Steel producer ArcelorMittal South Africa (AMSA) is moving ahead with a study into the production of green hydrogen directly reduced iron (gHDRI) at its mothballed Saldanha Steel Works, in the Western Cape. Market and product development head Jerry Dungu told participants at an industry conference that the JSE-listed group had signed a memorandum of understanding with a “developer of transformational energy solutions” to advance the production of gHDRI at the plant.
