Latest miracle hydrogen energy solution - who knows?
Scientists Invent Super Clean Hydrogen Fuel Technique That Could Save Us All
Probably too much to hope for, but it sounds slightly maybe promising. It's a technique for using hydrolysis on sea water with further processing of the reaction that consumes and isolates acid and increase bicarbonate.
Quote:
It goes like this: First, you apply electricity to salty water. This well-studied technique, called electrolysis, breaks water into oxygen and hydrogen gas, said Greg Rau, study co-author and researcher at Lawrence Livermore National Laboratory in Livermore, California.
While this is happening, acid is produced at the negative end of the electrode, called the anode. Usually, after the current stops being applied, the acid recombines with the base (hydroxide) produced at the electrode's positive end (cathode), turning back into water.
But Rau's team added another step and encased the anode in a silicate rock, one of the most abundant types of rock on Earth. The acid reacted with the basic rock, creating salts and more water.
By using up the acid produced during electrolysis, the water then became quite basic, filling up with hydroxide ions, Rau said. Ordinary air was then bubbled through the solution. The carbon dioxide present in the air reacted with the hydroxide to create bicarbonate, another base present in the bodies of many marine animals like corals and oyster shells.
