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.

From the manufacturing of our favorite devices to using them for social interactions, our digital lives can have a big climate impact.
Earth’s ongoing fever threatens to push entire forests toward this heat limit — and possible death.
This dangerous trend appears relatively new — and growing. Studies also have begun linking it to our warming world.
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.
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 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.
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.
Living corals could be frozen for safekeeping. Scientists could later revive them to restore reef ecosystems that are withering in warming seas.
Challenges from human-caused climate change, deforestation and degradation leave the fate of this vast forest uncertain.
