With the rise of solar power comes a great hurdle — bringing it into households. While scientists at the University of Exeter have masterminded glass solar blocks, those at UC Berkeley are working down to the atom. To bring cheaper options to the table, UCLA research teams are testing a solar gadget that creates hydrogen and electricity.
Along with the usual positive and negative electrodes, the device has a third electrode that can either store energy electrically or use it to split water into its constituent hydrogen and oxygen atoms – a process called water electrolysis.
The pocket-fitting tool produces clean energy to power appliances and vehicles. It also incorporates nickel, iron, and cobalt into hydrogen production, replacing platinum, which is scarce.
“Hydrogen is a great fuel for vehicles: It is the cleanest fuel known, it’s cheap and it puts no pollutants into the air – just water,” says [study head Richard] Kaner.
With a lot of work, UCLA’s newest contraption could do wonders for infrastructure and hydrogen cars. It may even bring a little sunshine to rural communities.
