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. 1 milliohm).

EIA: natural gas-fired reciprocating engines are being deployed more to balance renewables

Green Car Congress

Because these units can start and stop quickly and operate at partial loads, they have become increasingly important in areas with high shares of renewable electricity generation from wind and solar. The plant, which started commercial operation in 2011, consists of 18 reciprocating engine generators with 9.1

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5

Study suggests arrays of closely-spaced counter-rotating vertical-axis wind turbines could enhance power density of wind farms by up to an order of magnitude

Green Car Congress

Dabiri suggests using optimized arrays of smaller vertical-axis wind turbines to increase the power density and reduce the cost, and visual, acoustic, radar and environmental impacts, of wind farms using giant horizontal-axis turbines. constraint limits the amount of power that can be extracted from a given wind farm footprint.
