Hydrogen is a clean fuel, but making it usually takes fossil fuels, until now: A new discovery allows hungry bacteria to eat dirty water to make the fuel.
There aren't very many hydrogen cars on the road these days, but there might be soon. And when there are, it will be possible to take the dirty water from your toilet and turn it into fuel.
Is hydrogen actually clean, or just clean compared to fossil fuels? Even though it mostly produces water, there are some nasty side effects no one is talking about.
Producing hydrogen and oxygen from water is often a dirty process. Researchers at Monash University may have found a solution in birnessite, a mineral often found as a black stain on rocks.
Scientists at CalTech are developing a technique that converts water, air, and sunlight into different kinds of fuel that could power everything from car engines to fuel cells in cell phones. It sounds almost too good to be true.
This past April, we spoke with a startup that had a grand plan for an East Coast hydrogen highway. That plan is now one step closer to reality with this week's news that SunHydro has built its first hydrogen fueling station.
A new survey from the Big Four accounting firm shows that more than two thirds of major corporations globally plan to spend up to 5% of their revenues on carbon cutting initiatives over the next two years.
