U of Illinois team models capabilities of hybrid-electric propulsion systems for general aviation aircraft

Green Car Congress

Researchers at the University of Illinois at Urbana-Champaign have utilized a series of simulations to model the performance of twin-engine hybrid-electric general-aviation propulsion systems. The same sensitivities were studied with a series hybrid-electric drivetrain. Their paper appears in the Journal of Aircraft.

Hybrid biomass flow battery stores electricity and produces valuable chemicals at the same time

Green Car Congress

Rechargeable batteries store electricity in their electrode materials, while redox flow batteries use chemicals stored in tanks attached to the electrodes. Researchers have now developed a battery system based on a hybrid cell, which not only stores and provides electricity but also produces valuable chemicals in a flow system.

Swedish researchers explore use of carbon fiber as active electrode in structural battery for electric vehicles

Green Car Congress

Researchers in Sweden are exploring the use of carbon fiber as an active electrode in a multifunctional structural Li-ion battery in an electric car; i.e., electrical storage is incorporated into the body of the car. This can result in a weight reduction for electric vehicles. (Photo: Peter Larsson) Click to enlarge.
