I'm not a believer in man-made climate change. The climate was changing 100s of millions of years before mankind ever trod on this rock. However, I am a believer in man-made pollution. The evidence is all around us, and to Me, this is a great threat to the quality of life for people in the future. Like everyone else, I have people who will have to live here going forward, and with the birth of my great-granddaughter a week ago, I'm more concerned with a quality local environment over some hair-on-fire fearmongering climate Bovine Scat.
But that doesn't mean I'm against researching and learning new ways to clean up after ourselves. I found this article very interesting in that it hits towo of those concerns. Cleaning up local enviroment and creating an affordable and cleaner fuel.

Scientists turn wastewater contaminants into hydrogen fuel
Scientists at RMIT University have developed a method to harness heavy metals and other contaminants in wastewater to boost green hydrogen production, potentially addressing both water scarcity and clean energy challenges simultaneously. The technology transforms what has traditionally been an environmental liability into a catalyst for sustainable fuel generation.
The research, published in ACS Electrochemistry, demonstrates how platinum, chromium, nickel and other metals naturally present in wastewater can be captured and repurposed to accelerate the water-splitting process that produces hydrogen12. This approach eliminates the need for expensive purification steps typically required for hydrogen production.
The experimental system uses specially designed electrodes with carbon surfaces made from agricultural waste that attract metals from wastewater to form what researchers call "cocktail catalysts"1. These mixed-metal catalysts prove more efficient at conducting electricity and speeding up hydrogen production than traditional purified water methods.
"The advantage of our innovation over others to produce green hydrogen is that it harnesses wastewater's inherent materials rather than requiring purified water or additional steps," said Associate Professor Nasir Mahmood, lead researcher from RMIT's School of Science12.
The process works by placing two electrodes in partially treated wastewater and powering the system with renewable energy. As electricity flows through the water, it triggers chemical reactions that split water molecules into hydrogen and oxygen1.
The research builds on RMIT's broader platform of innovations for producing hydrogen from challenging water sources, including previous breakthroughs with seawater splitting and biosolids conversion12. The university won the 2024 Water Minister's Climate Innovation Challenge for related work producing green hydrogen from solar energy and recycled water34.
Co-lead researcher Professor Nicky Eshtiaghi emphasized the technology's dual benefits: "Our innovation addresses both pollution reduction and water scarcity, benefiting the energy and water sectors"12.
With more than 80% of global wastewater discharged untreated, the approach offers potential to convert an environmental problem into clean energy production12. The team is now seeking industry partnerships to scale the technology for commercial applications.
