Hydrogen battery relieves the pressure for clean energy storage

Hydrogen offers many advantages for clean energy storage, but storing it generally requires either a lot of pressure, a lot of heat or both. To avoid the enormous pressures needed to store pure hydrogen in manageable volumes, researchers have looked at hydrogen compounds. However, so far these approaches have suffered a catalogue of issues from high operating temperatures impeding the energy efficiency and stability of devices to low hydrogen storage capacity. Now researchers led by Naoki Matsui and Ryoji Kanno at the Institute of Science Tokyo in Japan have developed an electrolyte that allows high performance hydrogen storage.
