A well-written report of a promising lab study. It gave thorough documentation of methods, materials, and results--so others could replicate the experiments. This sort of approach reduces the fire risk of lithium-only battery technologies and provides energy storage in an electrochemical form (battery) and a chemical form (hydrogen gas). The hydrogen gas is substantially more pure than what is produced by more typical forms of water electrolysis.

Possible difficulties will include the scaling-up of this process, availability of some of the components and chemicals, ensuring containment of any chemicals (3M sulfuric acid is one), and long-term (5-15 year) cost/benefit data.
