UW Madison chemists discover new way to harness energy from ammonia

Green Car Congress

A research team at the University of Wisconsin–Madison has identified a new way to convert ammonia to nitrogen gas through a process that could be a step toward ammonia replacing carbon-based fuels. It’s compressible, like propane, easy to transport and easy to store. —John Berry, corresponding author.

Kia and Hyundai to introduce solar roof charging on selected vehicles: HEV, BEV and ICE

Green Car Congress

This power is converted and stored in the battery, or utilized to decrease load on the vehicle’s alternating current (AC) generator, thereby increasing vehicle range. The solar roof is the first of these technologies, and will mean that automobiles no longer passively consume energy, but will begin to produce it actively.

BMW exploring heat pumps and infrared for BEV and PHEV cabin heating systems

Green Car Congress

In battery electric vehicles (BEVs) or automobiles using plug-in hybrid technology (PHEVs), the Efficient Dynamics strategy is aimed primarily at increasing the electric range. In contrast, in systems employing infrared heating surfaces, energy is converted into infrared radiation, which then warms the occupants’ bodies directly.
