Low-Cost, Corrosion-Free Water Splitter Created From Silicon And Nickel (via Clean Technica)

A low-cost means of producing hydrogen fuel — one that doesn’t result in the corrosion of the materials used, and uses nothing but sunlight and water — has been created by researchers at Stanford University. The new silicon-based water splitter…

    Very interesting what has to be factored in is the cost of materials and return. Solar has not been the most economical even as the cost drops and efficientcies have risen but has benefited from the envirionmental aspect.
    What needs to be deterimined is:
    1) If the cost of the H2 production this way
    would rival fossil if used for burning instead of fuel cell.
    2) Is the cost of the solar power (higher than
    most in dollars) electricity generated more than the return in H2 energy. I must say I was dismayed by the repeated answers for literally
    years that electrolysis was the “only” way to produce H2 from water and that it was too expensive and that the power in was more then the energy out. Of course the “expert” answer was illogical, not credible, superficial and frustrating.

    Unfortunately the article does not mention the efficiency of this process. The use of fuel cells will really take-off if H2 can be made with very little energy. From that moment solar cells and wind mills may locally produce H2 and that will give a boost to solar, wind and fuel cell technology. Does someone know the efficiency of the water splitting process (Binding energy H2O vs and the splitting energy of this new process)?

    But one can do the same with any PV panel coupled with an electrolysis device and electrolysis efficiency can be up to 80%. Of course, if the efficiency is much better than with PV, then it might have a relative edge, but even then, it’s a drawback if the whole device needs to be hydrogen tight instead of only a small electrolysis cell.

    Very interesting and promising technology. If it can be scaled for commercial production it is just one more method that can be used to power the world. Hydrogen generated with this method might actually be cost effective. Currently most hydrogen for use is manufactured by striping it from CH4 (steam reforming), which is not an energy efficient methodology, i.e. it is less than one. Ignoring CO2 release which steam reforming also does it is more energy efficient to burn the CH4 than to change it to H gas. If the Stanford University process can be powered by the sun, PVs for the electricity they are using along with direct sunlight to finish the process a true cost efficient hydrogen economy could be created. I don’t believe that enough hydrogen can be created to power the world by this method, but I also don’t believe that any one source should or can provide all of are energy needs.

    It will be cheap H2 supplier for lenr reactor.
