A self-contained water system pumped threw an affixed turbine which rotates a shaft to two high output alternators and the electricity generated then goes to a battery bank is far more simple and applicable to what is available to every person . I have been using this system for my house and garage for over four years ... it has paid for itself at this point and I will be connecting my neighbors garage this year and getting a small payment which will cover any maintenance ....these complex systems are just that complex to the point that they leave no space for independence . With all of the ideas they keep playing with the cardinal “KISS” rule is ignored....for such an essential commodity to ignore it is a prime example of book smart street stupid.
Assuming that they can find an insurer willing to deal with large volumes of pressurized hydrogen storage, then it would be far more efficient to convert the hydrogen to electricity with fuel cells than to simply burn it. Molten carbonate fuel cells are cheap, work at these elevated temperatures and do well with pure hydrogen.
How many acres per kilowatt will they have to purchase?
How do they plan to store the power generated?
How big is the demand for Hydrogen?
How much will they charge per hydrogen unit?
How many decades to recover initial costs?
How big a taxpayer subsidy will they need?
Does any of these ‘hydricity’ plants generate as much as one modestly sized coal fired plant?
Does the coat per kilowatt even approach that of a coal or gas plant?
That very-high pressure hydrogen leaks directly through most conventional (ie, “affordable”) pipe steels.
But, this is green energy. Who cares how much it costs, and high inefficient it really is?
imho greatest way to use this tech is to combine it with water desalination like waterfx does.
