One of the challenges standing in the way of South Africa becoming a world-class green hydrogen producer is that South Africa is a water-scarce country, and that enormous volumes of water are needed to produce hydrogen, law firm Bowmans associate Marga Jordaan has said. “[We] need to take into account sustainable water use for communities, which is also a constitutional right, and to weigh that up with the economic growth in respect of the export and production of hydrogen,” Jordaan said at a seminar at Bowmans' offices in Sandton on November 29.
