New study shows a rapid increase of diesel-fueled backup generators across California

Green Car Congress

New research by economic and public policy consulting group M.Cubed finds a proliferation of backup generators across California, with nearly 90% being diesel-fueled, posing significant obstacles to achieving greenhouse gas reduction targets and driving nearly $136 million in annual health costs. Of these, 20,907 are diesel-fueled.

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. It took us a long time to get the data needed to let us connect to the grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.

OptiFuel to repower Argentina’s 400 freight locomotive fleet from diesel-power to CNG and/or RNG

Green Car Congress

Traditional locomotives run on diesel fuel, emitting high levels of NO x , PM, and CO 2. OptiFuel is developing modular repower kits for diesel locomotives and new locomotives in all lengths, horsepower levels, and track gauges. For line-haul operations in the US, RNG is the only practical zero-emission diesel-alternative solution.

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

Green Car Congress

IPG’s project will demonstrate the role of Flameless Ceramic Turbine technology in bringing EV charging to high-use and remote locations through clean, cheap, grid-independent power generation. But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable.
