Laboratory for Transport Phenomena in Energy Systems - Carnegie Mellon University

Advancing sustainable energy technology

At the Laboratory for Transport Phenomena in Energy Systems, we research several sustainable energy technologies and their applications, including fuel cells, batteries, supercapacitors, and CO2 capture technologies.

With ever-increasing concerns over climate change and energy independence, the development of sustainable energy systems and pollution abatement technologies are prominent on the global agenda. However, significant research and development are required to realize sustainable energy technologies that are economically feasible and publicly acceptable.
