On the curve, week ending 2026-06-01
This week’s items track two concurrent stories. The first is accelerating energy storage capacity – Ford Energy launches a utility-scale battery subsidiary and CATL’s sodium-ion chemistry reaches manufacturing readiness – while copper scarcity and US tariff uncertainty constrain the grid build-out that storage depends on. The second is sovereignty by other means: Amazon Leo expands satellite internet beyond Starlink’s lead, and military right-to-repair legislation documents what physical self-reliance looks like when written into procurement law. The common thread is the gap between what the energy transition requires and what the physical supply side can currently deliver.
- Ford launches a battery storage manufacturing subsidiary targeting 20 GWh of annual capacity.
On 11 May, Ford announced Ford Energy, a wholly owned subsidiary designed to manufacture and deploy utility-scale battery energy storage systems for grid operators, data centres, and industrial customers. First customer deliveries are targeted for late 2027. The move responds to record planned utility-scale storage additions: the US grid is set to add 24 GW of new battery capacity in 2026 alone, and Ford positions itself as a domestic manufacturer in a supply-constrained market.
Why it matters: US manufacturing resilience for critical energy infrastructure directly addresses energy sovereignty and productive tools within the FR thesis, reducing dependency on Asian battery storage supply chains.

- CATL secures the world’s largest sodium-ion battery order with a 60 GWh three-year supply agreement.
On 27 April, CATL and Chinese system integrator HyperStrong announced a partnership representing roughly half of CATL’s total energy storage shipments in 2025. The sodium-ion cells exceed 300 Ah, offer 160 Wh/kg energy density, and maintain platform compatibility with CATL’s existing lithium cells, enabling deployment across existing supply chains without a manufacturing overhaul. CATL confirmed it has solved key production challenges around energy density, foaming, and moisture control, signalling mainstream-ready sodium-ion manufacturing.
Why it matters: Scaling a non-lithium storage chemistry reduces dependency on lithium supply chains and creates redundancy in grid-scale energy storage, directly addressing the bounded materials and energy sovereignty categories.

- The US faces a 150,000-tonne copper supply deficit in 2026, with a refined copper tariff decision due by 30 June.
The Trump administration’s April clarification set 25% tariffs on derivative copper goods, with a 30 June deadline for the Secretary to advise on whether to extend tariffs to refined copper. At the same time, supply tightness from disruptions at Grasberg and Kamoa-Kakula mines is meeting surging demand from AI data centres and electrification, while China’s announcement to halt sulfuric acid exports (used in roughly 15% of global copper production) adds further upward pressure on refined copper pricing. An estimated 730,000 to 830,000 tonnes of inventory sits in US warehouses as traders hedge against the looming tariff decision.
Why it matters: Copper scarcity and tariff-driven pricing volatility directly constrain renewable energy and grid infrastructure build-out, making this a live test case for the bounded materials thesis covered in Why copper is the quiet protagonist of the AI boom.

- Amazon Leo (Project Kuiper) enters commercial satellite internet service in mid-2026, with 302 production satellites already deployed.
Amazon CEO Andy Jassy confirmed during Q1 2026 earnings that the satellite internet constellation will open to customers in mid-2026, following FCC approval to expand the planned constellation to 7,727 total satellites. As of April 2026, 302 production satellites are on orbit. The network uses inter-satellite optical links to route data between nodes as an IP-based mesh, competing directly with Starlink’s operational lead of over 6,000 satellites and millions of subscribers.
Why it matters: Commercial competition across multiple satellite constellations strengthens communications sovereignty by reducing single-provider dependency and driving redundancy into long-range connectivity infrastructure.

- Senators Warren and Sheehy renew the push for military right-to-repair authority after provisions were stripped from the 2026 defence authorisation bill.
In May 2026, a bipartisan group introduced the Warrior Right to Repair Act for inclusion in the 2027 National Defense Authorization Act, after the same provisions were removed from the 2026 NDAA following strong contractor lobbying. The legislation would require defence contractors to supply the technical data and materials needed for military personnel to service their own equipment, ending mandatory manufacturer service dependency in the field. The push mirrors broader civilian right-to-repair progress: one-third of Americans now live under some form of right-to-repair policy at the state level.
Why it matters: Defence self-reliance and permanence through repairability reduce contractor lock-in and extend the operational life of critical equipment, directly serving the permanence and repairability category within the FR thesis.
