CNN —In Nelson Mandela Bay, in the Eastern Cape of South Africa, thousands of hectares of land could one day become the world’s largest green ammonia plant. But by using renewable energy, “green” ammonia can be manufactured, slashing the carbon footprint of agricultural production and opening up the compound to further uses. ‘A completely green process’The process to make green ammonia is quite simple, Loubser says, requiring just water, air and energy. But green ammonia could also be burned in existing coal-fired power plants to quickly reduce their CO2 emissions, the study notes, or in plants customized to run entirely on ammonia. And many of the systems that will make use of green ammonia – including ship engines – are still under development, which is why production levels are low at the moment.
