Researchers are developing photoelectrochemical cells to push green hydrogen directly from water, without importing energy from power plants.
The centerpiece of this solar simulator is a tiny photoelectrochemical cell, capable of pushing hydrogen from water without the need for standalone renewable energy facilities .
Green hydrogen is a new development on the scene, having been made possible by the falling cost of wind and solar power since the early 2000s. Loosely speaking, a photoelectrochemical cell cuts out the energy middleperson. In contrast to electrolysis systems that import electricity from standalone facilities, the photoelectrochemical cell is an all-in-one device that deploys sunlight to catalyse a chemical reaction in water.
Nevertheless, science loves a challenge and work continues apace. In the latest development, last week a research team at the University of Tübingen in Germany announced a milestone in their effortsThe heart of the effort is a new high-efficiency solar cell.
“This means that permanent smaller stand-alone solutions for energy supply are also conceivable,” Schmidt adds.Next steps include transferring the technology to a more economical silicon-based platform along with a continued focus on stability and cost. At a time when the global economic and military might of the US should be focused squarely on helping its allies — namely, Ukraine and Israel — thePhoto : The centerpiece of this solar simulator is a tiny photoelectrochemical cell, capable of pushing hydrogen from water without the need for standalone renewable energy facilities .I don't like paywalls.
