Sandia innovation eliminates reliance on rare-earth magnets for large-scale wind turbines

Green Car Congress

Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. Most of the current utility-scale wind turbines are dependent on rare-earth magnets, Koplow said.

Bosch starts production of 800V inverter, motor for electric vehicles

Green Car Congress

Active parts (rotor and stator) of 800-volt technology for electric vehicles The standout features of the 800-volt variant of the Bosch electric motor now going into volume production are 830 N·m torque and 460 kW output. The SiC chips also increase the inverters’ efficiency to as much as 99%.

Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

bp and EnBW successful in ScotWind offshore wind bid; potential generating capacity of 2.9GW, up to £10B of investment

Green Car Congress

bp and EnBW have been awarded a lease option off the east coast of Scotland to develop a major offshore wind project to be known as Morven. The E1 lease is in an advantaged area, allowing the partners to develop it as a fixed-bottom offshore wind project with a total generating capacity of around 2.9

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. Energy source. Natural gas.
