Researchers discover cheaper and more efficient way to produce hydrogen through electrolysis

  We used to have cars that ran on tap water in the 1970's and cars that ran on electromagnetic batteries in the 1920's. Technology that has been suppressed and hidden from us.

A team of researchers from the Australian National University (ANU) discovered a cheaper and more efficient way to produce hydrogen through electrolysis.

The researchers led by Dr. Siva Karuturi found a way to produce hydrogen through electrolysis without an external source of electricity and any carbon emission. Their research has been published in Advanced Energy Materials.

The method used by the researchers is called the solar-to-hydrogen approach because they used the sunlight directly instead of using the electricity produced by solar panels. The method also reduced the cost of electrolysis by using inexpensive materials as semiconductors.

“There are significant cost benefits to this solar-to-hydrogen approach as it eliminates the need for added infrastructure that’s necessary when hydrogen is produced using an electrolyzer,” Karuturi said.

The researchers used a combination of perovskite cells with specially designed Si electrode to absorb the sunlight. To ensure its stability, the perovskite cells were improved by research co-author Dr. Heping Shen, who is an expert in perovskite.

The solar-to-hydrogen approach also uses noble-metal such as platinum, but the researchers are already at work to find a cheaper alternative.

With their method, the researchers increase the energy conversion efficiency of electrolysis to 17.6 percent, which is close to the 20 percent conversion rate of a solar panel....<<<Read More>>>...
