Samsung SDI's solid-state cells passed OEM qualification, Peak Energy broke ground on the first US grid-scale sodium-ion plant, and CATL shipped both an eight-minute-charge chemistry and a 5 GWh sodium-ion order for Europe — all in a week when the largest renewable project in US history went fully live and Beta's eVTOLs started carrying organs instead of headlines. The bottom line: energy tech spent the week converting lab and pilot results into procurement contracts, gigafactory groundbreakings, and OEM sign-offs — the transition from roadmap to industrial schedule is now the story, not the chemistry itself.
Samsung SDI reported positive safety and energy-density feedback from global automakers on its all-solid-state battery samples and reaffirmed a 2027 mass-production target.
CATL unveiled a fleet-oriented cell chemistry rated for 8C charging — a full charge in roughly eight minutes — with enough density for about 400 km of range.
Peak Energy started construction on a sodium-ion battery manufacturing facility in Sacramento, targeting utility storage contracts by 2027.
CATL's Tener Sodium cells will fill 5 GWh of European grid storage through Dutch integrator Alfen, with installations starting in 2027.
LONGi certified a 35.5% efficient perovskite-silicon tandem cell in the lab, beating its own April 2025 mark of 34.85%.
Researchers identified the mechanical process by which lithium dendrites fracture ceramic solid electrolytes and demonstrated a surface treatment that suppressed cracking under high-rate cycling.
SunZia Wind and its companion transmission line entered full commercial operation, moving New Mexico wind power to Arizona and California over a 550-mile HVDC line.
Masdar reached financial close on a project pairing 5.2 GW of solar with 19 GWh of storage to deliver 1 GW of firm, round-the-clock power.
Beta Technologies flew its eIPP aircraft on genuine operational missions — organ transport flights of roughly 275 nautical miles between Maryland and Virginia.
Lazard put utility solar at $24-96/MWh and onshore wind at $27-73/MWh — both cheaper than any new fossil plant — while gas peaking costs have risen 50% over five years.
