Williams and Erick Holguin) Capturing carbon emissions before they enter the atmosphere is a white whale for the fossil fuel industry. In theory, if a power plant or a factory could easily eliminate carbon emissions by filtering them out of […]

Electric cars could store energy in their carbon fiber bodies

Electric cars typically need larger, denser batteries if they’re going to meet the range expectations of people used to gas-powered vehicles, but available space and weight limit the size of that battery. Researchers might have a solution: turn the very body of the car into a battery. They’ve conducted a study showing that carbon fiber […]

CA Gov. says 100% clean electricity not enough, state must go carbon neutral

(credit: Reyner Media / Flickr) On Monday, California Governor Jerry Brown signed a bill mandating that the state’s utilities move to 100-percent zero-emission electricity generation by 2045. Brown also issued an executive order today requiring the state to become carbon neutral by 2045, that is, mandating that the state remove as much greenhouse gas from […]

How to design carbon taxes

ECONOMISTS view pricing greenhouse-gas emissions as an elegant way to reduce them. There are more than 70 national and regional schemes, covering perhaps a fifth of global emissions, which charge polluters for the carbon dioxide they belch out. But that leaves an awful lot of the world to be convinced of the merits of such […]

Can California's Carbon Queen Recycle Pollution?

If tickets to Mars were on sale, Etosha Cave would be the first in line — and she’d prefer a one-way trip, thank you. “If you want to be an explorer, you go out there and make it your home,” she says. Cave’s personal moonshot is metamorphosing environment-polluting carbon dioxide into useful products like petroleum. […]

‘Proton’ battery uses cheap carbon instead of lithium

A big challenge for the EV and renewable energy revolution is that the much-needed batteries are made from lithium, a relatively rare and pricey metal. Rather than focusing on other metals like magnesium, a team of scientists from RMIT University in Melbourne have figured it out to build rechargeable “proton” batteries from abundant carbon and […]
