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%.

Mercedes-Benz Cars aims to cut vehicle CO2 emissions by 50% over lifecycle by end of this decade

Green Car Congress

Mercedes-Benz plans to cover more than 70% of its energy needs through renewable energy by 2030 by rolling out solar and wind power at own sites as well as through further Power Purchase Agreements. Additional CO2 savings are expected to be achieved through further measures—i.e.,

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. This stored energy is then available as backup whenever there is an insufficient supply of solar and wind power. Type of CO2 source (biogas; waste water; atmosphere).

How EVs Are Reducing Carbon (CO2) Emissions

Blink Charging

The upstream, “well to wheel” emissions of the EV are linked to electricity generation and the electrical grid, with lower emissions in regions that use more renewable energy sources. The post How EVs Are Reducing Carbon (CO2) Emissions appeared first on Blink Charging. Let’s not forget our carbon footprint.

Lessons from a year with solar power

EV Info

It was one year ago that we decided to add solar panels to our roof. With two Electric cars, at the time a Nissan Lean and Mitsubishi Outlander, we use a considerable amount of electricity but not much petrol, so already we were a reasonable way down the less CO2 road. Panels: JA Solar black. Power is watts.

PHEVLERs are the Zero CO2 Clean Green Machines of the Future

Green Car Congress

On the other hand, drivers of other vehicles waste considerable time making special trips to refuel their internal combustion engine (ICE) vehicles at the liquid fuel station or their battery electric vehicle (BEV) at the rapid recharging station. PHEVLERs make our electric grid more efficient. [

Empa researchers investigating new process for production of synthetic methane

Green Car Congress

The gaseous product of the methanization reaction thus contains a few percent hydrogen, which prevents direct feeding into the gas grid; the hydrogen must first be removed. Both hydrogen production and methanization continuously generate waste heat.
