Five Cool Tech Demos From the ARPA-E Summit

Cars That Think

Chilldyne optimized the cold plate using corkscrew-shaped metal channels, called turbulators, that force water around them “like little tornadoes,” maximizing the heat absorbed, says Harrington. The company developed the cold plate under an ARPA-E grant and is now measuring the energy savings of liquid cooling through an ARPA-E program.

Georgia Tech team develops highly efficient multi-phase catalyst for SOFCs and other energy storage and conversion systems

Green Car Congress

Researchers at Georgia Tech, with colleagues in China and Saudi Arabia, have developed a rationally designed, multi-phase catalyst that significantly enhances the kinetics of oxygen reduction of the state-of-the-art solid oxide fuel cell cathode. The ions meet to make water, which exits the fuel cell.

Virginia Tech researchers develop high-energy-density sugar “biobattery”, an enzymatic fuel cell

Green Car Congress

A Virginia Tech research team led by Dr. Y.H. Percival Zhang has developed a high-energy-density sugar “biobattery”—a sugar-fueled fuel cell based on a synthetic enzymatic pathway. Enzymatic fuel cells containing a 15% (wt/v) maltodextrin solution have an energy-storage density of 596?Ah?kg

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

The technology to produce hydrogen by electrolyzing water has been around for more than 200 years. Green hydrogen production requires electrolyzers, solar and wind parks, and clean water—about 10 liters per kilogram of hydrogen generated. The home base for much of our PtX-focused research is the Energy Lab 2.0
