The Hydrogen Stream: AEM electrolysis could deliver hydrogen at $3.27/kg, say Repsol, P2HP Power to Hydrogen (P2H2) and Repsol completed a 1,250-hour pilot of P2H2’s hybrid AEM electrolyzer technology, demonstrating operation at 40% to 100% load, pressures up to 30 bar and hydrogen purity of up to 99.9%. P2H2 projects an LCOH of €3.86 ($4.47)/kg, potentially falling to €2.82/kg under optimized renewable energy conditions, and the companies are considering a 500 kW-to-MW-scale demonstration.

Iron-mediated cathode enables 206 Wh/kg sodium-ion pouch cell Chinese researchers have developed an iron-mediated strategy that improves the reversibility and stability of lattice-oxygen redox reactions in sodium-ion battery cathodes. A 15.8 Ah pouch cell using the cathode achieved an energy density of 206 Wh/kg, with lattice-oxygen redox reversibility reaching 99%.
