Battery equipment and cell industry trends from the second week of August, including the Ultium Cells plant restart and non-lithium battery funding.
An LCOE comparison of solar-plus-ESS and green hydrogen co-firing. The application splits at a discharge duration of 4 hours.
Seoul metro data center grid impact assessments have a 2.1% approval rate. Compared with the AIDC Special Act exemption from February 2027, when to start interconnection design.
An HVRT order applies to solar inverters of 500kW or more from January 1, 2026. Why it must be handled as an interlock layer independent of LVRT, with an I/O map and PLC logic.
Hyundai Motor and Kia began a 200kWh UBESS demonstration with LG Energy Solution and others. Used packs have different histories, so the SOH and internal resistance spread between packs must be interlocked first.
DC vs. AC coupling is decided not by efficiency but by whether the ESS must charge from the grid and whether one inverter may be a single point of failure.
How to sequence a UAT-to-SAT bus transfer after a generator trip: residual-voltage and phase-angle interlocks, method fallback logic, and why a GCB changes the premise.
PEMFC stack life is driven by potential cycling, high-potential dwell and start-stops, and most countermeasures are control settings: voltage ceiling, ramp rate, purge sequence.
PWR and BWR compared by where the radiation boundary sits, with decision criteria based on maintenance organization, power control, and supply chain.
When dry-room dew point rises, stop the moisture-exposed process, not dehumidification. 2oo3 voting, cause signals, staged stops and return conditions.
