A Nature Energy paper couples alkaline electrolysis with waste heat desalination. At 250 kW it reports 48 Nm3 per hour of hydrogen; ENB checks the water balance and finds an open question.
A Nature Energy paper lifts lithium-sulfur voltage from 2.05 V to 2.54 V with a three-electron sulfur reaction. ENB tests the 1,700 Wh/kg headline against first principles and shows why the stack-level estimate is 477 Wh/kg.
