Stopping fires before they start—how a salty solution is giving lithium metal batteries a safety check
Researchers have long considered lithium metal batteries to be the "holy grail" for energy storage. They have high energy density—how much energy a battery carries relative to its weight. This means they can be made smaller ...

Cash, carbon, crude—how to make oil fields bury emissions
In February 2018, Donald Trump signed into law new tax credits that reward oil companies for capturing carbon dioxide and preventing it from entering the atmosphere – either by burying the gas underground or by pumping ...

How to suck carbon dioxide from the sky for fuels and more
Someday, the gasoline you buy might trace its heritage to carbon dioxide pulled straight out of the sky rather than from oil pumped out of the ground. By removing emitted carbon dioxide from the atmosphere and turning it ...

Once we can capture CO2 emissions, here's what we could do with it
The thousands of metric tons of carbon dioxide (CO2) emitted from power plants each year doesn't have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture ...
