For decades, the global economy has lived in the shadow of the Strait of Hormuz. This narrow waterway, through which roughly one-fifth of the world’s total liquid petroleum flows, has served as the ultimate geopolitical lever. For policymakers, energy security meant ensuring that ships could move through these maritime chokepoints without interference. The logic was simple: if the oil stops flowing, the world stops turning.
As the global economy pivots toward a net-zero future, there is a prevailing sense that we are escaping this volatility. By swapping imported oil for domestic wind and solar power, nations hope to decouple their national security from the whims of distant regimes and the fragility of shipping lanes. Yet, this shift is not eliminating strategic vulnerability; it is simply relocating it. The energy transition supply chain risks of the 21st century are moving from the water to the refinery.
While we may eventually stop worrying about tankers in the Persian Gulf, we are entering an era where a handful of processing facilities and mineral deposits represent the new “Straits of Hormuz.” The risk is no longer just about the transit of a fuel, but the concentrated control over the materials required to build the technology that captures that fuel.
From Maritime Chokepoints to Industrial Bottlenecks
The traditional energy paradigm was defined by the logistics of extraction and transport. Oil and gas are consumed as they are moved. The most dangerous points in the chain were the physical bottlenecks—the straits and pipelines. If a conflict closed a waterway, the impact was immediate and systemic.
The renewable energy economy operates on a different logic. Solar panels, wind turbines, and electric vehicle (EV) batteries are not consumed; they are infrastructure. The vulnerability here is “front-loaded.” The risk occurs not during the operation of the energy system, but during its construction. To build a single EV battery, a manufacturer needs lithium, cobalt, nickel, and manganese, along with a suite of rare earth elements for the motor magnets.
The critical bottleneck is rarely the mine itself, but the processing. While minerals are found in various parts of the world, the capacity to refine them into battery-grade chemicals is staggeringly concentrated. According to the International Energy Agency (IEA), China currently dominates the processing of the vast majority of critical minerals, including nearly 90% of rare earth elements and a significant majority of lithium and cobalt refining.
| Feature | Fossil Fuel Era | Clean Energy Era |
|---|---|---|
| Primary Risk | Transit & Distribution | Extraction & Processing |
| Key Chokepoint | Maritime Straits (e.g., Hormuz) | Refining Hubs & Smelters |
| Impact Timing | Immediate (Daily supply) | Delayed (Infrastructure build-out) |
| Dependency | Resource-rich nations | Processing-dominant nations |
The Geopolitics of the Periodic Table
This concentration of processing power creates a new form of strategic coercion. In the old model, a country might threaten to cut off oil exports to spike prices or cripple an economy. In the new model, a dominant processor can restrict the export of refined graphite or gallium, effectively halting the production of semiconductors or batteries thousands of miles away.
This is not a theoretical risk. We have already seen the emergence of “mineral diplomacy,” where access to critical materials is used as a tool of statecraft. For countries attempting to meet aggressive climate deadlines, this creates a paradox: to achieve energy independence from fossil fuel exporters, they must first accept a deep, systemic dependence on mineral processors.
The stakes are particularly high for the “critical minerals” list—a group of elements designated by governments as essential for national security and economic growth. These include:
- Lithium: Essential for high-density batteries.
- Cobalt: Crucial for battery stability and lifespan, largely sourced from the DRC.
- Rare Earths (Neodymium, Dysprosium): Vital for the permanent magnets in wind turbines and EV motors.
- Copper: The fundamental conductor for all electrification efforts.
Diversification and the Path to Resilience
Governments are now scrambling to build a “buffer” against these new bottlenecks. The strategy is shifting toward “friend-shoring”—building supply chains within allied nations—and investing in domestic processing capabilities to break the monopoly of single-nation dominance.
However, building a refinery is not as fast as signing a trade deal. Processing plants require massive capital investment, specialized technical expertise, and often involve significant environmental footprints that develop them politically unpopular in democratic nations. This creates a “time gap” where the world is moving toward renewables faster than it can build the secure infrastructure to support them.
Beyond diversification, the long-term solution lies in a circular economy. If the world can master the recycling of lithium-ion batteries and permanent magnets, the “mine-to-market” dependency decreases. In this scenario, the waste stream of the 2030s becomes the “mine” of the 2040s, effectively neutralizing the geopolitical leverage of any single geographic chokepoint.

The next critical milestone for global energy security will be the implementation of the EU Critical Raw Materials Act and similar U.S. Initiatives, which aim to set strict targets for domestic extraction and processing by 2030. These policy frameworks will determine whether the clean energy transition leads to true independence or simply a new set of dependencies.
