Earth’s Oldest Rocks May Hold the Key to Clean Hydrogen Energy
Scientists have discovered that ancient rocks deep beneath Canada are naturally releasing hydrogen gas, offering new evidence that Earth, itself, may contain significant untapped sources of clean energy. Using data collected in Ontario for over a decade, researchers found enough hydrogen to power more than 400 households annually.
Scientists Use Sunlight to Turn Plastic Waste Into Fuel
Researchers at Adelaide University have outlined processes for converting discarded plastic into clean hydrogen fuel using solar-powered technologies. The study in Chem Catalysis highlights how plastics rich in carbon and hydrogen can be repurposed as an energy source rather than waste – a potential pathway toward a more sustainable circular economy.
This Coal Town Is Heating Its Buildings With Water From Abandoned Mines
Cumberland, British Columbia, is reimagining its coal mining past as a clean energy opportunity. Water trapped in abandoned mine tunnels could be used in a geothermal system to heat and cool buildings efficiently and with minimal emissions. This eco project could anchor a community-wide shift to low-carbon heating and cooling.
New Device Turns Seawater Into Drinking Water With Zero Waste
Scientists have developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine. Laser-textured metal panels use sunlight to evaporate water while automatically directing salt deposits away. The system captures nearly all dissolved salts as solid materials and can also recover lithium from leftover materials.
New Study Warns We May Have Surpassed What Earth Can Support
According to a sweeping new study by Flinders University analyzing more than 200 years of population and environmental data, humanity may already be living far beyond what Earth can sustainably support. Researchers found that current consumption is outpacing planetary boundaries. The findings are intended to accelerate action on sustainable resources.
