Five items this week, the first post-enforcement issue. The EU Right to Repair Directive entered force on 31 July – three days ago. US grid battery deployment is running 60% ahead of last year on already-record installations. A quieter story in battery supply chains: cobalt’s price collapse and the LFP shift that caused it. A specific product release timed well ahead of the home battery buying guide on this site. And the ECB publishing its digital euro design specification, which raises a question worth thinking about.

  1. EU Right to Repair obligations entered force on 31 July 2026 – manufacturers must now accept repair requests retroactively for all products sold before the enforcement date.

The EU Right to Repair Directive (Directive 2024/1799) became enforceable across all member states on 31 July 2026. The retroactive element is the part most manufacturers were not prepared for: the obligation to repair at reasonable cost and within a reasonable timeframe applies to products sold before the enforcement date. Manufacturers must maintain spare parts availability for up to ten years after sale. Consumer warranties extend by 12 months when repair is chosen over replacement. The European Commission will launch a pan-EU online repair platform by July 2027; in the interim, national market surveillance authorities are responsible for enforcement actions.

Why it matters: The enforcement date is behind us. The first regulatory actions at national level and the first legal challenges to the “reasonable price” standard for parts will define what the directive means in practice. Manufacturers who built repair access into their products from the start – Framework and Fairphone being the named examples on this site – are not affected by enforcement. The argument for buying repairable hardware before the broader market normalises repair access is in the right-to-repair piece.

  1. US battery storage installations on record pace: 24.3GW planned for 2026, up 60% on 2025 – Q1 alone was the largest quarter on record at 9.7GWh.

US energy storage developers have committed to 24.3GW of new utility-scale battery capacity for 2026, representing 28% of all planned US power capacity additions. Q1 2026 saw 9.7GWh of battery storage installed, a 32% year-on-year increase and the largest first quarter on record. Texas, California, and Arizona account for approximately 80% of the pipeline. Total US installed battery storage capacity is projected to exceed 45GW by end of 2026. Battery storage has overtaken gas peakers as the primary source of grid firming capacity in the planning pipeline.

Why it matters: Grid-scale deployment at this rate normalises battery storage as critical infrastructure rather than an optional asset. The economic case for residential equivalents is downstream of this curve: as grid-scale installed cost falls and operating history accumulates, the technology risk for residential buyers shrinks. The energy sovereignty explainer covers the argument for the household application.

  1. Cobalt prices have fallen 70% from their 2022 peak as EV manufacturers shift to lithium iron phosphate chemistry – LFP now accounts for over 55% of global EV battery production.

London Metal Exchange cobalt prices fell from approximately USD 81,000 per tonne in March 2022 to under USD 25,000 per tonne by 2024, a 70% decline, driven by DRC production increases and deliberate supply chain diversification by battery manufacturers. Lithium iron phosphate (LFP) chemistry, which contains no cobalt, now accounts for over 55% of global EV battery production according to the Cobalt Institute’s 2025 annual report, up from 15% in 2020. Tesla, BYD, and CATL have all standardised on LFP for standard-range and mass-market applications. The shift reduced cobalt demand growth from what was projected in 2021 forecasts by approximately 40%.

Why it matters: The cobalt story is the exception that clarifies the rule. Where manufacturers could substitute away from a finite material with concentration risk, they did – and the price collapsed. Rare earths, copper, and lithium do not have the same substitution pathways at comparable cost and performance. The LFP shift demonstrates that supply chain diversification is achievable where the chemistry allows it, and confirms why the materials without substitutes are the ones worth watching.

  1. Bluetti launches Pioneer Na sodium-ion portable station rated to -25C discharge – and FridgePower, a plug-and-play home backup specifically for essential loads.

Bluetti’s CES 2026 product announcements included two items relevant to energy sovereignty in cold climates. The Pioneer Na is a portable sodium-ion power station rated for discharge down to -25 degrees Celsius, addressing the capacity degradation that makes standard lithium-ion units unreliable in Finnish, Scandinavian, and northern European winter conditions. Standard LFP batteries lose 20 to 30% capacity at -20C; sodium-ion chemistry maintains performance significantly better at low temperatures. The FridgePower is a separate unit designed specifically to keep refrigerators and essential household loads running during outages, without requiring permanent installation. It targets the partial-backup use case rather than whole-home storage.

Why it matters: The sodium-ion cold-climate performance is the practical development here. Nordic off-grid and cabin users have been limited by lithium chemistry’s temperature floor; a -25C discharge rating changes that calculation. The home battery buying guide covers the LFP options for mainstream use; the Pioneer Na adds a category for cold-climate deployment not previously viable at this price tier.

  1. ECB publishes digital euro design specification – offline functionality confirmed, programmability limits legally codified, but the infrastructure for restrictions exists whether used or not.

The European Central Bank published its digital euro design specification in mid-2026, covering the architecture for a retail central bank digital currency available to individuals and businesses in the euro area. Offline functionality for in-person payments without internet access is confirmed as a design requirement. The ECB also codified legal limits on programmability: digital euros cannot be programmed to expire, restrict purchasing categories, or be conditional on compliance with external criteria. Both the infrastructure and the legal prohibition were published together, which means the prohibition is the operative safeguard – the infrastructure to program restrictions exists in the design regardless.

Why it matters: A CBDC is a digital claim on a central bank, not a physical asset. It has no counterparty risk in the traditional sense but carries a different kind of exposure: the terms of holding and spending are set by the issuing institution and can change by policy update rather than contract amendment. The real assets framework from Alden, Doomberg, and Gromen is relevant here – the argument for holding assets without a central issuer is partly about what a CBDC makes explicit: that currency is a government liability, and physical assets are not.
