For a long time, the only possible way to harvest hydrogen from water molecules was through the Photo-Electro-Chemical (PEC) cells.
These PEC cells utilize noble metals in their functions, which are both expensive and carbon-heavy. However, Indian Institute of Technology Guwahati researchers have found a new way to conduct this process, and it’s a lot less expensive than the PEC cells in multiple ways.
This graphene-based process is completely solar-powered and lacks the expensive noble metals that were being used in their previous versions of the process, making hydrogen harvesting both better for our environment, and our pockets.
