The Geopolitics of the Ocean: Washington’s Unilateral Seabed Bet
Polymetallic nodules for deep-sea mining and EV battery storage
While energy headlines remain fixed on domestic grid constraints and land-based mining permits, a regulatory filing posted by NOAA on August 19 marks a major structural shift in global resource competition. At issue: deep-sea mining for the raw materials used for battery storage.
A Unilateral Bypass of International Ocean Law
By reactivating the 1980 Deep Seabed Hard Mineral Resources Act, the U.S. government has opened a path for domestic permits covering 1.6 billion metric tons of polymetallic nodules in international waters. This unilateral maneuver bypasses the long-delayed rulebook of the International Seabed Authority, drawing immediate criticism from Beijing and Paris while testing the limits of international ocean law.
The strategic rationale is simple: battery-grade nickel demand is expected to triple by 2030, and China controls the overwhelming majority of global cobalt refining. However, with major commercial OEMs pledging to avoid deep-sea minerals over ecological concerns, Washington appears prepared to backstop the market itself through Defense Production Act mandates and strategic defense stockpiling.
Whether this legal end-run succeeds commercially and diplomatically will define who controls resources across the two-thirds of the planet beyond sovereign borders.
The move signals a broader shift in how critical minerals are prioritized under national security mandates. As Washington pushes forward with domestic permitting, the ultimate test will be whether state-backed stockpiling can overcome severe international resistance, environmental litigation, and market hesitancy before commercial harvesting begins.
