hydrogen storage capacity of selected activated carbon electrodes made from brown coal - lithium ion battery for solar storage

Electric storage of hydrogen in activated carbon (aC)
The electrode, as part of a reversible fuel cell, provides a potentially attractive option for storing surplus electrical energy from the inherent variable solar and wind sources.
This system-which we call proton-flow batteries-promises to have round-trip energy efficiency comparable to that of lithium-ion batteries, with higher weight and bulk energy density at the same time.
Activated carbon with high internal surface area, high pore volume, light weight and easy to obtain has attracted considerable research interest as a solid material
