In 10 seconds? Scientists have discovered a way to process wastewater that produces hydrogen. The tech one day could be used for energy storage or powering zero-emission cars.
Why is it a big deal? We save money and energy on treating wastewater (which is normally a very energy-demanding process) and we get hydrogen fuel for our future, climate-friendly cars! Consider this: transportation is responsible for a huge, chunk over 20% of our global greenhouse gas ‘emission pie’. And road transport accounts for about 75% of that 20%. This means that if we managed to turn all those trucks, cars, and buses into zero-emission vehicles, we'd take a big step toward reducing greenhouse gas emissions. Hydrogen is currently touted as a possible energy source for such vehicles.
