Researchers show economic, environmental and grid-resilience benefits of converting diesel trains to battery-electric

Green Car Congress

Dramatic improvements in battery technology, coupled with the existing electric drivetrain in predominantly diesel-electric freight trains in the US, pave the way for a rapid conversion to battery-electric freight rail and with substantial cost savings. Popovich, N.D., Rajagopal, D., Nat Energy 6, 1017–1025 doi: 10.1038/s41560-021-00915-5.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

The conversion normally requires significant amounts of energy in the form of high heat—a temperature of at least 700 ?C, Illustration of a novel room-temperature process to remove CO 2 by converting the molecule into CO. An array of light beams impinging upon the grid would activate the LSPs. Credit: NIST.
