Namibia Fires Up Africa’s First Green Hydrogen Hub

Namibia has commissioned Africa’s first integrated green hydrogen facility at Walvis Bay, combining solar power, hydrogen production and battery storage for industrial and transport use.

The CMB Tech Namibia facility uses a 5MWp solar park, a 5 megawatt (MW) proton exchange membrane electrolyser and a 5.9MWh battery storage system to produce green hydrogen off-grid.

The project is being positioned as Africa’s first fully integrated green hydrogen facility, with its initial output earmarked for industrial and transport applications, including dual-fuel trucks, generators and a hydrogen-powered freight locomotive.

In a statement issued yesterday, Siemens sub-Saharan Africa chief executive Sabine Dall’Omo says the facility demonstrates that large-scale clean energy production can already be achieved on the continent.

“Africa’s first fully integrated green hydrogen facility demonstrates that large-scale clean energy production is not a future ambition, but a present-day reality,” Dall’Omo says.

The facility is located at Walvis Bay, where solar power is used to generate electricity for an electrolyser that separates water into hydrogen and oxygen.

The hydrogen can subsequently be combined with nitrogen to produce ammonia, which could eventually be used as a marine fuel.

CMB Tech chief technology officer Roy Campe describes the facility as a “living lab” for an integrated hydrogen economy.

“The facility includes a solar-powered off-grid electrolyser for renewable hydrogen production, a refuelling station for hydrogen-powered vehicles and industrial applications, and an on-site Hydrogen Academy for local talent development,” Campe says.

The 6.5-hectare solar park currently has about 7 000 solar panels. Campe says the company intends to significantly expand the facility, with a long-term target of reaching 250MW and eventually 500MW of capacity.

Campe says the broader ambition was to position Namibia as an energy-exporting hub.

“We want to turn Namibia into a global energy hub and export energy to Europe and the rest of the world,” he says.

The project’s initial focus is not export, but creating domestic demand for the hydrogen produced at the plant.

CMB Tech is using the hydrogen itself in its industrial operations, effectively providing an initial off-taker for the fuel.

Dall’Omo says securing demand is a major challenge facing hydrogen projects globally.

“Many green hydrogen projects are stalling because, while they invest heavily in solar energy and green hydrogen production, there is often no commercial offtake agreement in place to secure demand for the hydrogen produced,” she says.

The facility is expected to expand into port-related applications, including the production of green ammonia for potential maritime use.

This could allow hydrogen-derived fuels to be used in shipping, one of the sectors considered difficult to decarbonise.

Wiebke Polomka, senior manager for southern Africa at Afrika-Verein der deutschen Wirtschaft, says the project could provide a practical pathway for reducing emissions in transport and logistics.

“Beyond its role as an energy production facility, the project illustrates how green hydrogen can accelerate the decarbonisation of transport and logistics value chains,” Polomka says.

Local skills development is another component of the project.
