Not a very useful article, and it's weak on technical details. Hydrogen is a poor storage medium for energy for numerous reasons, such as steel embrittlement (it requires expensive special alloys for storage or transport under pressure). Hence, hydrogen-from-water is applicable where it can be generated and used immediately. There are three obvious industrial applications in cleantech: Ammonia production for fertilizer using atmospheric N2. Direct iron reduction for steel production, i.e. reduction of iron ore. Methane and jet fuel production utilizing atmospheric CO2 as the carbon source. In particular, steam reformation of natural gas to produce hydrogen should be eliminated as a hydrogen source, as the fossil CO2 produced is then released to the atmosphere.
