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

Green Car Congress

OptiFuel’s rail engine solutions are powered by their EPA-certified locomotive CNG/RNG engine rated at 0.00 The second challenge was engineering flexibility into the system—railroads had different performance needs and access to different sources of power. Then there was the challenge of new technology.

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

To provide 50%—or more—of power from clean energy sources, power grids will have to be able to leverage distributed energy sources, and reliably manage dynamic changes, while minimizing impact on customer quality of service. We will be replicating the entire California power grid on one campus.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

2021 was a big year for energy-related news, what with the ongoing hunt for new forms of energy storage and cleaner if not carbon-free electricity and events and research that spotlighted the weak links in our power grid. No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons.

The Greening of Transportation

Cars That Think

In this month’s special report on the greening of transportation, we examine a moonshot idea for powering electric vehicles, the biggest change in aviation since the jet engine, and cargo ships with a battle-tested mode of generation. The engineers you’ll find in this issue don’t have time for despair.
