Yeah right. This howler from Stanford University:

Single-catalyst water splitter from Stanford produces clean-burning hydrogen 24/7
Stanford University scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hours a day, seven days a week. 

The device, described in a study published June 23 in Nature Communications, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.

"We have developed a low-voltage, single-catalyst water splitter that continuously generates hydrogen and oxygen for more than 200 hours, an exciting world-record performance," said study co-author Yi Cui, an associate professor of materials science and engineering at Stanford and of photon science at the SLAC National Accelerator Laboratory.

Electrolysis is horribly inefficient - you spend much more energy than you can ever receive from the Hydrogen output. Catalysts are great but they only get you so far. It is still a $$$$$$ in and a $ out situation. That this device runs 24/7 has absolutely zero bearing.

I just invented a wonderful new machine! You shovel out your fireplace, put the ashes into the reaction chamber and connect a battery. In a few minutes, chunks of firewood begin to appear. My machine is just as viable as any electrolysis machine - water is an ash. Water is the product of combustion of hydrogen and oxygen. Reconstituting it back to the original elements takes a lot of effort - a lot more than will be produced when the two gasses are burned again.

I would love to be proven wrong but the science doesn't add up...
