The ESOI e ratio of storage in hydrogen exceeds that of batteries because of the low energy cost of the materials required to store compressed hydrogen, and a much lower overall energy efficiency than lithium ion
Like the War of the Currents 150 years ago, today another war is being imagined - "War of the Elements" for energy storage and transport, between hydrogen, as used in fuel cells and engines, and
Estimates for the energy intensity of lithium ion battery storage range from 86 to 200 MJ MJ −1. 47,49 This is several times our estimate of 28 MJ MJ −1 for compressed hydrogen storage in steel vessels. Energy storage in hydrogen
