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.

Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2

Green Car Congress

Water and oxygen are the only by-products. This enables them to take part in an accounting process that ensures that the amount of gas that they put in their vehicle at the natural gas filling station is supplied to the grid by the Audi e-gas plant. Payment and billing is handled via the Audi e-gas refueling card.

German power-to-gas facility opens green methanation plant; €28M STORE&GO project

Green Car Congress

While the current facility feeds pure hydrogen (“WindGas”) directly into the gas grid, the new methanation plant provides for the generation of “green” methane. The wind-to-gas pilot plant “WindGas Falkenhagen” was constructed in 2013 to store wind energy in the natural gas grid. Type of CO2 source (biogas; waste water; atmosphere).

Audi e-gas plant qualified to participate in balancing market to stabilize grid

Green Car Congress

The Audi e-gas plant in the city of Werlte in Lower Saxony ( earlier post ) produces CO 2 neutral-fuel (synthetic methane from water, renewable electricity and CO 2 ); it now also contributes toward stabilizing the public power grid. This has resulted in the plant being accepted under the direction of grid operator Tennet TSO GmbH.

Evonik and Siemens launch phase 2 of Rheticus: butanol, hexanol from CO2 and water using renewable electricity and bacteria

Green Car Congress

The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals. We are also contributing to the stability of the grid because production is so flexible that we can respond to fluctuations in power supply.
