Renewables, storage, grids, fusion and decarbonisation.
Motors draw nearly a third of US power, and few run on variable frequency drives. Slowing them to match demand frees capacity on the demand side, which grid hardware cannot do.
NTU Singapore's bias-free device swaps oxygen evolution for hydrazine oxidation, giving 25 mA/cm² and 72 hours of stable operation in seawater. The catch is that it needs the pollutant to work.
KIER and UNIST use micro-sized nickel oxide to oxidise spiro-OMeTAD, capture lithium ions and filter both out. Cells reached 25.24% efficiency and kept over 95% of it after 1,000 h at 85°C and 85% RH.
