"hydrogen storage severely limited by high energy consumption/ safety concerns because rely on extreme cryogenic cooling or high-pressure, bypassed utilizing localized, compact, electrochemical cycling: magnesium metal/ hydrogen gas as electrodes driving hydrogen-electricity co-storage... converts intense heat normally wasted during standard hydrogen absorption directly into usable electricity, achieving 93.9% overall energy efficiency without needing extreme pressures/ temperatures... long flying drones"
