A solar and storage plant now delivers firm power to a Congolese copper complex, and Morocco has begun engineering a green ammonia plant rather than exporting hydrogen. Both are attempts to capture the processing step. Firm power was the hard part. It is not the last part.
Two announcements this week describe the same ambition on different continents.
CrossBoundary Energy has confirmed that its solar and storage plant serving the Kamoa-Kakula copper complex in the Democratic Republic of Congo has entered commercial operation, combining around 233 megawatts peak of solar with 526 megawatt-hours of battery storage to provide a firm 30 megawatt supply to the mine.
Separately, KBR has been selected for pre-FEED work on ORNX Green Hydrogen's proposed project near Laayoune, Morocco, supported by United States Trade and Development Agency funding. The integrated complex would use around 900 megawatts of electrolysers to produce roughly 560,000 tonnes of ammonia a year.
Neither is really an energy story. Both are attempts to capture the second step in a value chain: the move from concentrate to cathode, and from electricity to a chemical that can be sold. Morocco in particular is choosing not to export hydrogen or electrons but to convert them into a product with an existing global market and a ship that can carry it.
The reason this has been so hard in both cases is the same, and the Congolese numbers state it more precisely than any policy document has.
Read the Kamoa-Kakula configuration again. Two hundred and thirty-three megawatts peak of solar and five hundred and twenty-six megawatt-hours of storage produce a firm thirty megawatts.
That is roughly eight times the nameplate solar capacity for each unit of dependable supply, plus enough storage to carry the load through the night. This is what firmness costs in a system with no dispatchable backup worth relying on.
It matters because processing, unlike extraction, cannot be interrupted. A concentrator can tolerate a stoppage. A smelter, a refinery or an electrolyser cannot, or can only at considerable cost, because thermal cycling damages equipment and interrupted electrochemistry wastes product. Continuous industrial load is the hardest thing to serve from intermittent generation, and it is precisely the load that beneficiation requires.
So the constraint on African mineral processing has never been mainly about mineral policy or investor appetite. It has been that firm industrial power at competitive cost was unavailable, and that grid connections capable of supplying it did not exist. A private power-purchase agreement with enough storage attached is the first credible answer to that, which is why this plant is more significant than another mine installing panels.
The same logic runs through Morocco. Nine hundred megawatts of electrolysers only make sense where renewable resource is abundant enough that firmness can be bought by overbuilding, and where the resulting product can be stored and shipped rather than consumed instantaneously.
Firm power was the binding constraint. It is being solved. What follows is the part that receives far less attention.
Value addition faces a structural obstacle that has been documented for decades and is rarely mentioned in announcements of this kind.
Tariff escalation is the practice of applying higher duties to processed goods than to the raw materials they are made from. UN Trade and Development describes it plainly in the context of critical minerals: escalation discourages value-added exports and locks producers into the role of raw material suppliers. The effect is to tax exactly the step a country is trying to climb.
Raúl Prebisch and Hans Singer built an entire school of development economics on the observation that primary exporters tend to lose ground in relative terms to exporters of manufactures. The policy conclusion drawn from it in the 1960s, broad import substitution behind high walls, mostly failed and deserves its reputation. The underlying diagnosis about the composition of exports has aged considerably better than the prescription, and this week's two projects are that diagnosis being acted on with better instruments.
There is a complication in the current evidence that deserves more attention than it gets, because it points somewhere unexpected.
UNCTAD finds that tariff escalation is widely in place within Africa and other developing economies, not only in the markets they export to. African exporters can face lower tariffs in developed markets, where preferential agreements apply, than within their own region. Some of the barrier to African value addition is erected by African tariff schedules.
That is an uncomfortable finding and a useful one, because it identifies an obstacle that the countries concerned can remove themselves, on their own timetable, without negotiating with anybody. A government financing a smelter while maintaining duties that penalise processed imports from its neighbours is working against its own industrial strategy and paying for both sides of the contradiction.
Both value chains this week are attempts to move one step to the right.
Each step to the right raises the requirement for firm continuous power. It also raises the tariff typically applied to the exported product. Solving the first does not touch the second. This week's two projects address only the top row.
A buyer at a price that works.
Green ammonia's supply pipeline is considerably longer than its committed demand. Fertiliser buyers have shown limited willingness to pay a premium, and the shipping and industrial offtakes that would justify these volumes remain thin. A pre-FEED study is not a sales contract, and the projects that reach financial close will be the ones with an offtake attached rather than the ones with the best resource.
Operations and maintenance capability.
A refinery or an electrolyser complex requires a workforce that can run it for thirty years. That is the slow part; it cannot be procured with the equipment, and whether it is built locally or imported for the life of the plant is a policy choice usually made inside a procurement document.
A social settlement with the region.
This one is the least discussed and it changes most. A concentrate exporter employs relatively few people and buys little locally. A processing complex needs water, land, housing, roads, a labour market and a local supply chain, and it operates for decades. That is a fundamentally different relationship with the surrounding population, and the terms of it are set at design stage. What travels with an industrial operator into a new role is not only its technical capability.
For a government pursuing beneficiation, the useful sequence is not the one usually followed.
Audit your own tariff schedule before lobbying anybody about theirs. Confirm there is a buyer before financing the plant. Fund the operations capability on the timescale it actually takes. And establish what a processing complex will mean to the region around it while that is still a design question.
Firm power was the hard part, and it now has a working answer sitting in the Congolese copperbelt. It was never the only part.
The Lab works on this in local manufacturing and energy access, across the markets where processing is being attempted for the first time.
