Reimagine CO2

INSPIRING THE BRIGHTEST MINDS AROUND THE WORLD TO HELP SOLVE CLIMATE CHANGE.

A $20 Million global competition to develop breakthrough technologies that will convert CO₂ emissions from power plants and industrial facilities into valuable products like building materials, alternative fuels and other items that we use every day. Teams will be scored on how much CO₂ they convert and the net value of their products.

New fuel cell technology runs on solid carbon

Advancements in a fuel cell technology powered by solid carbon could make electricity generation from resources such as coal and biomass cleaner and more efficient, according to a new paper published by Idaho National Laboratory researchers.

The fuel cell design incorporates innovations in three components: the anode, the electrolyte and the fuel. Together, these advancements allow the fuel cell to utilize about three times as much carbon as earlier direct carbon fuel cell (DCFC) designs.

Too Good To Be True? Carbon Capture 'Game Changer' Raises Hopes And Questions

A potential breakthrough technology is being tested in Houston—a new kind of natural-gas power plant that captures and reuses what normally goes up the smokestack: carbon dioxide, heat, and water.

If it works, NET Power’s natural-gas plant promises no carbon emissions and no water use—it produces water instead—and this is the clincher: it promises to produce electricity at a cost competitive with existing power plants.

Climate's magic rabbit: Pulling CO2 out of thin air

While CO2 concentrations are now higher than they have been in at least 800,000 years, the gas still only accounts for a tiny 0.04% of our atmosphere.

However, extracting carbon dioxide from well mixed air is not just technically difficult, it's expensive as well.

A Clean Energy’s Dirty Little Secret

Discarded solar panels are piling up all over the world, and they represent a major threat to the environment. Clean energy may not be so clean after all.

A new study by Environmental Progress (EP) warns that toxic waste from used solar panels now poses a global environmental threat.

Post-Kemper question: Is 'clean coal' dead?

The possible end of Southern Co.'s flagship "clean coal" project in Mississippi isn't the death knell for carbon capture and sequestration technology, industry analysts say.

Instead, the problems at the Kemper County Energy Facility — which state regulators want to turn into a natural gas plant after years of delays and cost overruns — resulted from a unique series of events and a coal gasification system that was scaled up too fast.
