    Pollution power? A new device turns carbon dioxide into fuel

    Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.

    Offshore wind farms could do far more than just make clean power

    Offshore wind farms cost more than onshore ones. But their ability to make ‘green’ hydrogen and capture carbon dioxide could help this wind power pay off.

    Restoring giant underwater forests, one blade at a time

    Giant kelp are at risk due to climate change and human activities. In New Zealand, a community effort is rebuilding these underwater algal forests.

    Explainer: Why are so many hurricanes strengthening really fast?

    This dangerous trend appears relatively new — and growing. Studies also have begun linking it to our warming world.

    Hydrogen energy could help our climate — depending on its source

    Hydrogen energy doesn’t emit greenhouse gases when it’s used. But how it’s produced will affect how useful it can be in slowing climate change.

    Explainer: The hydrogen rainbow

    Hydrogen works the same, regardless of its source. But how clean or “green” it is very much hinges on its color-coded name — which points to how it was made.

    Engineers cook up a new way to tackle CO2: Make baking soda

    Engineers have found a material that can collect carbon dioxide from the air. When later mixed with water, it forms baking soda that can be shed in the sea.

    A new hydrogel could help pull drinking water from the air

    The salty gel absorbs more water from the air than similar gels, even in desert climates. This could provide clean water for drinking or farming.

    Adult corals have been frozen and revived for the first time

    Living corals could be frozen for safekeeping. Scientists could later revive them to restore reef ecosystems that are withering in warming seas.
