Name of the Project
Coega green ammonia project.
Location
Coega Special Economic Zone, alongside the Port of Ngqura, in Gqeberha, in South Africa’s Eastern Cape province.
Project Owner/s
Hive Hydrogen South Africa.
Project Description
The project aims to establish a green ammonia plant producing more than 900 000 t/y, with its own dedicated power supply.
The plan is for a combined 2 200 MW of renewable solar and wind energy to electrolyse 3.4 Mℓ/d of seawater as part of a desalination and hydrogen extraction process.
The project will be powered by a 1 000 MW solar plant, located adjacent to the plant, coupled with a 56 MW battery storage component on site, and a 1 200 MW wind farm, which will be built further away.
Proton exchange membrane, or PEM, electrolysers, which generally use South Africa’s platinum and iridium metals, will separate the hydrogen from the oxygen.
Nitrogen will be simultaneously extracted from the air using an air separation unit.
The hydrogen and nitrogen will then be combined through ammonia synthesis to produce green ammonia, which will be cooled, liquified and stored for export.
Once the ship arrives at the port, the liquid ammonia will be dispatched directly through a pipeline from the storage tanks and loaded onto the ship.
Potential Job Creation
The project will create more than 20 000 jobs.
Capital Expenditure
$5.8-billion.
Planned Start/End Date
The project is expected to reach full operation in 2028.
