Global energy storage and battery value chain Report Interpretation

Overview

This Battery Weekly update reviews developments across the global energy-storage and battery value chain. Its central message is that storage deployment and supply-chain localization remain active across regions, but market access restrictions, softer EV demand and technology-manufacturing constraints are reshaping where and how capacity is built.

Core views

The update highlights a policy-driven shift in the US energy-storage supply chain. President Trump's Executive Order 14420, signed on 26 August 2026, declares a national emergency and restricts procurement, imports and installation of certain foreign-made equipment in US transmission systems of 69 kV and above. The scope includes BESS, transformers, generators, inverters, industrial control systems and related software. The Department of Energy is required to issue implementation rules within 120 days and propose procurement changes within 180 days, with priority for US-made equipment. Bernstein notes that the announcement prompted a sharp sell-off in Chinese storage and inverter stocks because the US accounts for roughly 15–20% of revenue for several leading Chinese solar and storage companies; the expected effect is faster localization in US infrastructure alongside pressure to expand in the Middle East, Southeast Asia and Latin America. India is also pursuing localization, preparing an incentive scheme worth up to INR 130 billion (US$1.37 billion) for domestic production of cathodes, anodes, electrolytes, separator films and copper foil. These inputs are largely sourced from China, while only 40 GWh of India's existing 50 GWh battery-manufacturing incentive program has been awarded. The report links the new program to project delays caused by upstream-component shortages and frames it as support for energy security, EV and storage deployment, and a more competitive domestic battery industry. Octillion's new Halol facility adds more than 3 GWh of annual battery capacity, lifting its Indian total above 150,000 battery systems or about 9 GWh annually, with supply aimed at passenger EVs, commercial vehicles and buses. The weekly developments also show continued investment in stationary storage. Saudi Arabia signed contracts for four first large-scale BOO battery-storage projects totaling 2 GW/8 GWh and about SAR 4.35 billion (US$1.2 billion). Each project is 500 MW/2,000 MWh with four-hour duration and 15-year service agreements; a further 3 GW/12 GWh tender round is under way. In the UK, Field received irrevocable approval for the 200 MW/3,600 MWh, 18-hour Rigifa BESS in Scotland, selected under Ofgem's long-duration-storage support scheme. The project is intended to absorb excess wind generation and improve grid flexibility. KOWEPO and ACWA Power also agreed to pursue solar, wind and BESS projects in Uzbekistan, where renewable electricity is targeted to reach 40% of generation by 2030. Battery manufacturing and materials investment continues to become more regional. Lyten signed a letter of intent to acquire insolvent Norwegian battery maker Morrow Batteries, including a 1 GWh annual LFP facility in Arendal; Morrow's previous plan to expand to 43 GWh had been halted by funding constraints. Asahi Kasei opened a wet-process separator coating line in North Carolina, with commercial production scheduled for FY2026, to support EV and ESS demand and complement a planned Canadian separator plant. EcoPro BM is investing KRW 40 billion (US$30 million) to upgrade its 54,000-tonne Debrecen cathode plant for NCA and high-nickel NCM production; from Q4 2027 it is expected to supply a German premium automaker, with long-term expansion potential to 108,000 tonnes. In Korea's equipment and materials chain, Toptec won two Hyundai Mobis North American electrification-unit contracts totaling KRW 41.2 billion (US$30 million), equal to about 24% of its 2025 revenue. The orders cover a prismatic assembly line for extended-range EVs and a cylindrical assembly line for hybrids, reinforcing Hyundai Motor Group's planned North American hybrid and EREV push, including its first EREV in 1H27; Toptec's backlog stood at KRW 158.2 billion at end-June 2026. MOT shipped its first equipment for 46mm cylindrical mass-production lines, including laser welding, forming and inspection systems for tabless structures. Separately, SK Innovation plans to absorb SK IE Technology, targeting approximately KRW 60 billion of annual EBITDA improvement and a separator-business turnaround within two years; it will retain the Polish plant while closing Jeungpyeong and selling its Changzhou facility. Technology progress remains uneven. LG Energy Solution says solid-state batteries offer higher energy density, faster charging and improved safety, but large-scale manufacturing is the key obstacle to commercialization. It expects earlier use in smartphones, drones and premium vehicles rather than mass-market EVs or storage. LGES is advancing LMR batteries for GM vehicles from 2028, aiming for more than 400 miles of range at costs comparable with LFP, alongside 46-series cylindrical and sodium-ion batteries for storage. The report contrasts this cautious stance with Chinese manufacturers' pilot-production targets from 2027. Other ecosystem developments include CATL-backed Aiva's reported consideration of CATL's Choco battery-swap network, which had 2,000 stations in 180 Chinese cities and targets more than 3,000 by end-2026, and Sunwoda EVB's partnership with JD.com on standardized batteries, battery swapping and robotics applications. Market data in the report show strong one-year gains for several battery inputs as of 28 August: lithium carbonate spot prices were US$22,694 per tonne, up 100% over one year, lithium hydroxide spot was US$21,206 per tonne, up 93%, and cobalt spot was US$55,862 per tonne, up 70%. LFP spot cell costs were US$61/kWh, up 16% year on year, while LFP pack costs were US$74/kWh, down 1%. The company valuation table provides a cross-sectional view of cell makers, lithium suppliers, cathode producers, anode suppliers and separator companies, rather than a new report-wide rating conclusion.

Impact & implications

The report indicates that energy-storage deployment and regional manufacturing investment are continuing, but policy is increasingly determining access to major markets and supply-chain location. It also portrays hybrid and EREV equipment demand as supportive for selected equipment suppliers while solid-state batteries remain limited by manufacturing readiness.

Risks

• US restrictions on foreign-made grid equipment could reduce Chinese storage and inverter companies' access to a market that contributes roughly 15–20% of revenue for several leading firms.
• Battery projects in India have faced delays because of upstream supply-chain constraints and component shortages.
• Large-scale manufacturing remains the main hurdle to solid-state battery commercialization.
• SK Innovation's separator turnaround is occurring amid a prolonged EV-market slowdown.

What to watch

• US Department of Energy implementation rules due within 120 days and proposed procurement changes within 180 days under Executive Order 14420.
• Progress of India's battery-material incentive program and awards under its existing battery-manufacturing scheme.
• The second Saudi storage tender round totaling 3 GW/12 GWh.
• Execution of Hyundai Motor Group's first North American EREV launch planned for 1H27.
• Commercial production at Asahi Kasei's North Carolina separator line in FY2026 and EcoPro BM's Hungarian NCM supply start in Q4 2027.
