Canberra, May 11 -- In their latest studies into sustainable-eco-friendly energy, Australian researchers at the University of Adelaide have developed two innovative, energy-efficient systems that use urea from human urine and wastewater to produce cheaper green hydrogen.
The systems offer a cheaper and more sustainable alternative to conventional methods for generating clean hydrogen while turning waste into a valuable energy resource, a press release of the university said.
Hydrogen is typically generated by splitting water through electrolysis, a process that is costly and energy-intensive. While extracting hydrogen from fossil fuels is cheaper, it comes with high carbon emissions, it said.
By contrast, using urea, particularly from ur...
