Its got some nice by-products too, one of which is pure drinking water.
Well I wouldn't like to drink that water! Not unless it was 'doctored' with something beforehand. The water produced by hydrogen combustion is so pure that it won't even conduct electricity, but it isn't long before it does because it dissolves anything that will possibly form a solution with it (including rocks, steel and CO2). I prefer my water with a balanced variety of minerals in it. Especially C2-H5-O-H.

I notice your reference suggested harvesting the oxygen as well. To do this would make the process ecologically 'dirty'. If you harvest H2 and O2 from water, then burn the H2 and use the O2 for some other process the result is atmospheric O2 consumption (depending on the application for the harvested O2).
Harvest H2 for combustion and liberate the O2 into the atmosphere and all is well. Harvest both and use the O2 to form another product and the combustion of the H2 just removes 'other' O2 from the atmosphere causing greater stress to current atmospheric forcings. You can't have your cake and eat it! Thus, to include 'all' the processes from this reference is effectively 'ecologically unsound'.
When it is claimed that "The project is economically acceptable in power niche market and has good prospects of being competitive both commercially and ecologically" , the full commercial potential berates the ecological aspect. I just hope they don't go for the full on 'commercial profits' version. The ecological version is sound though.

PS. I just hit another 'bad patch' with the servers here.
