AfDB reimbursable grants are aimed at the least glamorous but most decisive stage of green hydrogen development: turning concepts into financeable projects.
Namibia’s green hydrogen ambition is entering the stage where technical enthusiasm has to be converted into bankable project structures. The African Development Bank has announced a package of reimbursable grants worth a total of $20 million for green hydrogen and derivatives projects in Namibia, Egypt, Morocco and South Africa, subject to board approval. The financing is modest compared with the billions of dollars required to build large hydrogen facilities, but its purpose is more strategic: to fund the project-preparation work that determines whether much larger pools of capital can eventually be mobilised.
That distinction matters because megaprojects do not fail only from lack of interest. They fail because feasibility studies are incomplete, offtake contracts are weak, infrastructure costs are unclear, environmental approvals are unresolved or financing structures do not allocate risk credibly. Project preparation is the bridge between an attractive concept and an asset that banks, pension funds, development financiers and strategic investors can actually finance.
Namibia has compelling natural advantages. Its solar and wind resources can support low-carbon electricity generation at scale, while the Atlantic coast provides a potential export route for hydrogen derivatives such as green ammonia. The country also has established mining activity, relatively strong institutions by regional standards and proximity to South African industrial demand. Those advantages explain why Namibia has featured prominently in Africa’s green hydrogen conversation.
But natural advantage is not bankability. Electrolysers, renewable generation, desalination, transmission, pipelines, storage, port facilities and export logistics have to operate as one commercial system. If any element is delayed or priced incorrectly, the economics of the entire project can change. Hydrogen therefore requires unusually tight coordination between energy policy, industrial planning, water infrastructure and logistics.
The AfDB’s intervention targets precisely that coordination gap. Reimbursable grants are intended to help selected projects prepare for investment, meaning that early-stage development risk is shared before commercial financing is expected to arrive. The grants can support technical studies, legal structures, environmental work, market analysis and other pre-construction requirements. These are expenditures that are essential but difficult to finance because the project is not yet generating revenue.
For Namibia, the policy implication is that the country should measure green hydrogen progress by investment readiness rather than announcement volume. A memorandum of understanding can generate headlines, but it does not create an operating plant. A bankable project needs credible power costs, verified water availability, an agreed land position, realistic engineering, a customer willing to sign an offtake agreement and a financing structure that distributes risk among parties capable of carrying it.
Offtake is particularly important. Hydrogen projects need buyers prepared to commit to long-term purchases at prices high enough to support capital recovery. European industrial decarbonisation creates potential demand, but buyers also compare Namibia with projects in the Middle East, Australia, Latin America and North Africa. Namibia must therefore compete not only on renewable resources but on delivery certainty, logistics and cost.
There is also a domestic value question. Green hydrogen can become an export commodity with limited local spillovers, or it can support a broader industrial strategy. Derivatives such as green ammonia and green iron offer the possibility of exporting more processed value rather than only hydrogen molecules. Namibia’s mining and metals base makes that particularly relevant. Cheap green power can support industrial activity that would otherwise be difficult to decarbonise.
The infrastructure developed for hydrogen can also create wider benefits if designed correctly. New renewable generation, transmission capacity, water infrastructure and port upgrades can support other industries. The danger is building dedicated systems that serve one enclave project while leaving the rest of the economy constrained. Public policy should therefore examine where shared infrastructure can lower costs across sectors without undermining project economics.
The AfDB grants are small in financial terms, but project preparation often has a multiplier effect. A few million dollars spent on credible studies and contracts can unlock hundreds of millions or billions in construction capital. The opposite is also true: weak preparation can strand years of political effort and investor attention.
Project preparation also gives government a chance to resolve social and environmental issues before construction pressure begins. Land access, water allocation, community benefit mechanisms and biodiversity impacts become far more expensive to solve after financing has closed. Early-stage funding should therefore be used to strengthen the social licence of projects as deliberately as it is used to refine engineering and financial models. That includes clarifying community benefits, local procurement expectations and the long-term ownership of shared infrastructure. Projects that solve those questions before financing are less likely to encounter expensive redesign, litigation or community resistance during construction.
Namibia’s next green hydrogen milestone should therefore not be another announcement. It should be a project that reaches financial close with transparent economics, dependable customers and infrastructure that can be delivered on schedule. Development finance is now being directed toward that objective. The test is whether Namibia can convert preparation funding into investable assets before global hydrogen capital moves elsewhere.
