Researchers in Sweden unveiled a new concept for producing hydrogen energy more efficiently, splitting water into oxygen and hydrogen without the dangerous risk of mixing the two gases.
Developed at KTH Royal Institute of Technology in Stockholm, the new method decouples the standard electrolysis process for producing hydrogen gas, which splits water molecules by applying an electric current. In contrast with prevailing systems, it produces the resulting oxygen and hydrogen gases separately rather than simultaneously in the same cell, where they need to be separated by membrane barriers
That separation eliminates the possibility of the gases mixing with the risk of explosions, says researcher Esteban Toledo, a Ph.D. student at KTH who co-authored the paper published today in Science Advances along with Joydeep Dutta, professor of applied physics at KTH. It also eliminates the need for rare Earth metals.
The two researchers patented the system, and a company, Caplyzer AB, was formed through KTH Innovation to scale the technology.
