A major green energy project in South Africa is advancing toward implementation, with its US$5.8 billion Hive Hydrogen initiative positioning the country as a potential global hub for clean industrial fuel production and low carbon shipping solutions.
The project, located in the Coega Special Economic Zone in Nelson Mandela Bay, has reached a significant milestone after selecting a US$1 billion electrolyser and green ammonia production system. Once completed, it is expected to produce around one million tonnes of green ammonia annually, a development that could significantly reshape global supply dynamics for clean maritime fuel.
Developers say the project could produce some of the lowest cost green ammonia in the world, a critical claim at a time when industries are under pressure to reduce carbon emissions, particularly in shipping, fertiliser production, and heavy industry.
The initiative is being led by Hive Hydrogen, backed by UK based Hive Energy and South African infrastructure firm BuiltAfrica. The project is designed to be powered by a large scale renewable energy system consisting of approximately 1,500 megawatts of wind power and 1,430 megawatts of solar capacity.
Danish energy technology company Topsoe will supply solid oxide electrolyser technology for the project, which developers say could significantly reduce infrastructure and electricity transmission costs, improving overall competitiveness.
Green ammonia is increasingly seen as a key alternative fuel for the global shipping industry, which is under mounting pressure from regulators to reduce carbon emissions. Unlike conventional fuels, ammonia can be produced using renewable energy and emits no carbon when used as a fuel, making it attractive for long distance maritime transport.
Industry analysts note that demand for ammonia powered vessels is rising quickly, with shipping companies increasingly investing in new propulsion technologies designed to comply with tightening global emissions rules. This trend is helping to shift green hydrogen and ammonia projects from speculative ventures toward commercially viable infrastructure.
The South African government has already designated the project as a “lighthouse” initiative, signalling strong political backing. Officials view the project as a strategic opportunity to position the country as a leading exporter of green industrial fuels, while also attracting large scale investment and boosting local industrial development.
Globally, the hydrogen sector is experiencing rapid expansion, with more than $110 billion reportedly committed to over 500 projects worldwide. China leads global investment, followed by North America and Europe, while countries such as Germany, Chile, and Namibia are also aggressively developing hydrogen capacity.
Germany, for example, is investing heavily in hydrogen import infrastructure, transforming ports such as Hamburg into future energy hubs. Meanwhile, energy companies like Shell are building large scale electrolyser projects expected to come online in the coming years.
Despite strong momentum, the green hydrogen sector continues to face challenges, including high production costs, infrastructure gaps, and uncertainty around long term demand. However, large scale projects like Hive Hydrogen are seen as critical to overcoming these barriers by achieving economies of scale.
For South Africa, the stakes are particularly high. Success could establish the country as a major exporter of clean energy fuels, diversifying its economy beyond traditional mining and fossil fuel dependency while creating new industrial opportunities linked to global decarbonisation efforts.
