The press releases are glowing. Japan and the United States have signed a memorandum of understanding to "secure" the supply chain for critical minerals by scraping the bottom of the Pacific Ocean. They call it a strategic alliance. I call it a desperate expensive hallucination.
While bureaucrats in Tokyo and D.C. high-five over the prospect of "energy independence," they are ignoring a fundamental economic reality. We aren't racing to the bottom of the ocean because it’s efficient. We’re racing there because we’ve failed to innovate on the surface. This pact isn't a masterstroke of 21st-century diplomacy. It is a subsidy-sinkhole that ignores the actual chemistry of the energy transition.
The Myth of the Infinite Nodule
The mainstream narrative suggests the ocean floor is literally paved with "batteries in a rock." They talk about polymetallic nodules—potato-sized chunks of manganese, nickel, cobalt, and copper—as if they are just sitting there waiting for a vacuum cleaner.
Here is the truth: the logistics are a nightmare that would make a SpaceX engineer sweat.
Mining these minerals requires operating heavy machinery at depths of $4,000$ to $6,000$ meters. At those depths, the pressure is roughly $600$ times that of the surface. You aren't just "gathering" rocks. You are attempting to run a continuous, high-output industrial operation in a high-pressure, pitch-black, corrosive saltwater environment that eats metal for breakfast.
I have watched venture capital-backed mining startups burn through hundreds of millions of dollars just trying to get a prototype crawler to move ten feet without collapsing. The "cooperation" between Japan and the U.S. is a tacit admission that neither country has the stomach to bankroll this absurdity alone.
China Won This Round Ten Years Ago
The common justification for this alliance is "de-risking" from China. It's a noble goal with a flawed execution. China currently controls roughly $60%$ of global rare earth production and an even higher percentage of the processing capacity.
The U.S.-Japan pact focuses on the extraction. This is the classic Western mistake.
If we successfully pull a million tons of nodules from the Clarion-Clipperton Zone (CCZ), where do you think they will go to be refined? Unless Japan and the U.S. build a massive, environmentally grueling, and legally fraught onshore processing infrastructure simultaneously, they will just be shipping raw materials back to Chinese-owned refineries.
You don't win a resource war by finding the dirt. You win it by owning the furnace. Currently, the U.S. has one major rare earth mine at Mountain Pass, and for years, it had to ship its ore to China just to get it processed. This new agreement is like bragging about finding a new oil field while your enemy owns every refinery on the planet.
The Sodium Ion Elephant in the Room
The most egregious oversight in the U.S.-Japan seabed strategy is the assumption that we will always need these specific minerals.
The mining industry is betting on a static tech stack. They assume the 2035 battery will look exactly like the 2023 battery, just bigger. They are wrong.
- Cobalt is dying: Tesla and BYD are already pivoting toward Lithium Iron Phosphate (LFP) batteries. LFP uses zero cobalt and zero nickel.
- Sodium-Ion is coming: For stationary storage and low-end EVs, sodium-ion batteries—which use salt—are entering mass production.
Imagine a scenario where the U.S. and Japan spend the next decade and $15$ billion dollars perfecting deep-sea robot vacuums to hunt for cobalt, only for the global market to shift entirely to solid-state or sodium-based chemistries. By the time the first commercial-scale ship docks with a load of seabed ore, the "critical" minerals inside might be about as valuable as coal in a solar farm.
We are spending "new-tech" money to solve an "old-tech" problem.
The Regulatory Mirage
The International Seabed Authority (ISA) is a toothless entity currently being bullied by corporate interests and national egos. The U.S. isn't even a member of the United Nations Convention on the Law of the Sea (UNCLOS), which governs the ISA.
Japan is pushing forward because they have the exclusive economic zone (EEZ) around Minamitorishima island, but the U.S. is essentially a squatter in these negotiations. This "team up" is a legal fiction designed to soothe investors. They are trying to create a "rules-based order" for a territory where the rules are currently being written in pencil by people who have never seen the ocean floor.
The Hidden Cost of "Clean" Energy
Let's drop the "green" pretense. You cannot strip-mine the benthic layer of the ocean without destroying ecosystems we haven't even mapped yet.
Proponents claim deep-sea mining is "cleaner" than terrestrial mining because it doesn't involve "human rights abuses" in the DRC or "deforestation" in Indonesia. This is a false choice. We aren't choosing between a child in a cobalt mine and a robot in the ocean. We are choosing between a linear "dig it up" economy and a circular "recycle it" economy.
The U.S. and Japan produce millions of tons of electronic waste every year. That waste is a "mine" that sits on the surface, doesn't require high-pressure submersibles, and is already in our backyard. But recycling isn't sexy. It doesn't involve giant ships and "strategic alliances." So we ignore the goldmine in our junk drawers to chase ghosts at the bottom of the sea.
Follow the Money, Not the Press Release
If you want to know if this pact is real, look at the private sector. Are the major miners like Rio Tinto or BHP diving in? No. They are staying on the sidelines, watching smaller, "pure-play" companies like The Metals Company (TMC) take all the risk.
The big players know that the CapEx (Capital Expenditure) for deep-sea mining is a nightmare. To make a single deep-sea site profitable, you need a commodity price environment that stays at historic highs for twenty years straight. One breakthrough in battery recycling or a shift in cathode chemistry and your multi-billion dollar ship becomes a very expensive paperweight.
The Actionable Pivot
Stop looking for more holes to dig.
If the U.S. and Japan actually wanted to secure their futures, they would stop signed "cooperation agreements" for speculative mining and start doing three things:
- Mandate Battery Circularity: Force manufacturers to design for disassembly. If you sell a battery in the U.S. or Japan, you should be legally responsible for reclaiming $95%$ of its minerals at the end of its life.
- Subsidize the Process, Not the Ore: Build the refineries. If you can process the material, it doesn't matter where it comes from. You hold the leverage.
- Invest in "Material Agnostic" Tech: Stop betting on specific elements. Bet on the physics of energy storage.
This agreement is a distraction. It's a way for politicians to look like they are doing something about "resource security" without actually confronting the difficult task of building a domestic industrial base. They are literally looking for buried treasure because they can't figure out how to run a factory at home.
Don't buy the hype. The seabed isn't the future of energy. It’s just the latest place for governments to drown their capital.
Stop digging. Start building.
