Principle of hydrogen energy storage

How much energy do you need to store hydrogen?

Except for CGH 2 and LOHC, one has to spend about one-third of the energy contained in hydrogen (LHV) or more to store it. LOHC is believed to be the most energy-saving hydrogen storage technology. However, this understanding is based on the full utilization of the heat released during the hydrogenation process.
