Professor Gallant News + Media
Removing carbon dioxide from power plant exhaust
Assistant Professor Betar Gallant is developing a battery that could both capture carbon dioxide in power plant exhaust and convert it to a solid ready for safe disposal.
New battery gobbles up carbon dioxide
A lithium-based battery developed by Assistant Professor Betar Gallant could be made partly from carbon dioxide captured from power plants, helping reduce greenhouse gas emission.
Tackling Greenhouse Gases
Faculty in MIT's Department of Mechanical Engineering are developing technologies that store, capture, convert, and minimize greenhouse gas emissions using a variety of approaches.
