Mercedes-Benz EQE SUV makes its debut along with AMG version

Green Car Congress

The modular drive concept enables high overall performance and a long range. The magnets—and thus the rotor—follow the rotating alternating current field in the stator windings. In the EQE SUV, Mercedes-Benz uses a pull-in winding for a particularly strong magnetic field. This also reduces the use of rare earths.

Audi unveils e-gas project: synthetic methane from the methanation of green hydrogen; series production of CNG models in 2013 powered by e-gas

Green Car Congress

Respectively, each one is suitable for a very different type of drive concept: for electric cars, fuel-cell vehicles and CNG vehicles. The e-gas project consists of two main components: Audi is contributing to the construction of offshore North Sea wind turbines which will generate clean power,that is then fed into the public power grid.

Bars for different years in the same pathway represent improvements in the costs of the specific pathway, based on specific reference data for the appropriate year and pathway. Distributed production options under development include reforming of bio-derived renewable liquids and electrolysis of water. Source: DOE. Click to enlarge.

France’s IFPEN studying industrial potential of onshore sources of natural hydrogen

Green Car Congress

In the future, hydrogen produced through water electrolysis is expected to be used to store energy as a way of compensating for solar or wind power’s intermittent output. In addition to being a carrier of energy, hydrogen could also be a source of energy, and its combustion would emit water (H 2 O) instead of CO 2.

How to Build EV Motors Without Rare Earth Elements

Cars That Think

Along with colleagues from the National Renewable Energy Laboratory , Ames Laboratory , and the University of Wisconsin, Madison, we have been studying advanced motor concepts as part of the U.S. What makes the motor spin is a phenomenon called magnetic reluctance, which refers to how much a material opposes magnetic flux passing through it.
