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

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, An array of light beams impinging upon the grid would activate the LSPs. The team tapped a novel energy source from the nanoworld to trigger a common chemical reaction that eliminates carbon dioxide.

Montauk Renewables signs LOI with European Energy to provide CO2 for e-methanol production in Texas

Green Car Congress

Montauk Renewables captures methane, preventing it from being released into the atmosphere, and converts it into either RNG or electrical power for the electrical grid. The planned delivery would prevent biogenic CO 2 from entering the atmosphere and put it to beneficial use, creating a new fixed-price commodity revenue stream for Montauk.

Mercedes-Benz Cars plants in Germany to be supplied with CO2-neutral energy from 2022

Green Car Congress

Today, new plants in Europe are already planned with a CO2-neutral energy supply from the start. With a CO2-neutral energy supply of the plants, we are consistently pursuing this approach and are actively driving sustainability in production. This ensures a reliable power supply even in fluctuating grids.

United announces investment in, commercial agreement with Dimensional Energy; CO2-to-SAF

Green Car Congress

At the Tucson site, they are using electricity from the Arizona grid, which gets an increasing amount of power from local solar panels. Commissioning of the facility has already begun, and it is set to begin operation this July. Dimensional’s technology can run on all forms of renewable energy.
