Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. The compressor gets the supercritical CO 2 up to the necessary pressure before it meets up with waste heat in the recuperator and returns to the heater to continue the cycle. The recuperator improves the overall efficiency of the system.

Climeworks launches world’s first commercial plant to capture CO2 from air; potential for CO2-neutral fuels

Green Car Congress

In Hinwil the DAC plant has been installed on the roof of a waste recovery facility—operated by the municipal administration union KEZO—with its waste heat powering the Climeworks DAC plant. In comparison to other carbon capture technologies, a modular Climeworks plant can be employed almost anywhere.

Turbo, air-hybrid Scuderi split cycle engine achieves 64 mpg US in simulations; CO2 emissions of 85 g/km

Green Car Congress

The comparison is based on a consumption and emissions analysis of 10 typical four-seat small cars ranging from the Audi A1 to the Fiat 500 to the Toyota AYGO, all fitted with the most economical Otto engine variant. The design is also optimized for air hybridization (when a small air tank is applied to capture and reuse wasted energy).

New Audi paintshop at Ingolstadt; heating energy & water per car down by 20%, CO2 by 30%, VOCs by 90%; bell-bell

Green Car Congress

Five‑percent less waste (paint sludge) is created for each car that is painted. This comparison helps to prevent possible production flaws in the electronic quality process, with support from an electronic quality inspection. With the bell‑bell method, paint is applied only electrostatically, thus achieving higher efficiency.
