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. The Brayton cycle is named after 19 th century engineer George Brayton, who developed this method of using hot, pressurized fluid to spin a turbine, much like a jet engine.

Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix. Or is it better to liquefy it on site at the airport?

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

IPG secured the £1 million as part of the Highways England (HE) and Innovate UK’s £20-million innovation call to invest in projects that can help improve air quality and operation of England’s roads. Grid access and capacity issues, as well as the infeasibility of on-site solar and wind, is a barrier for EV charging in many locations.

This Clock Made Power Grids Possible

Cars That Think

On 23 October 1916, an engineer named Henry E. As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. And Warren, who eventually solved the grid-frequency problem, was actually working on a different puzzle when he came across the answer.

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

Green Car Congress

At the recent 2021 United Nations Climate Change Conference, the US joined a dozen other countries in signing onto new agreements to curtail shipping emissions, and zero-emissions solutions for freight rail transport will be part of that commitment. Historically, diesel-electric trains have been used as power generators during emergencies.
