This company wants to use carbon dioxide to store renewable power on the grid

Compressing gases to store energy isn’t new: for decades, a few facilities around the world have been pumping air into huge underground caverns under pressure and then using it to generate electricity in a natural gas power plant. But Energy Dome turned to carbon dioxide because of its physics. Carbon dioxide, when squeezed to high […]

Conductive polymers could wind up being a major player in grid storage, but whether that happens will likely depend on how quickly the company can scale up its technology and, crucially, how much the batteries cost, says Susan Babinec, who leads the energy storage program at Argonne National Lab.  Some research points to $20 per […]
