Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Under illumination for 6 hours, the optimized reduced titania-Cu 2 O photocatalyst enables 0.13% photoreduction of highly diluted CO 2 with water vapors to 462 nmol g ?1 What if we drew inspiration from photosynthesis, the process by which plants use sunlight to convert CO2 and water into useful chemicals?

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

C using waste heat from a nearby geothermal plant to release the CO 2 molecules. Water from the Hellisheiði power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth. The water returns to the cycle of the geothermal power plant.

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

Green Car Congress

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. —Rodney Keith, manager for the advanced concepts group working on the Brayton cycle technology. It may not sound super significant, but it was quite a path to get here.

Empa researchers investigating new process for production of synthetic methane

Green Car Congress

All these concepts have advantages and drawbacks in terms of energy, operation and economics. Empa researchers hope that this novel process engineering concept will lead to simpler process control, higher efficiency and better suitability for dynamic operation. Construction of the plant is planned for mid-2021. Schröter K.,

$12M German project to develop technology for syngas production from CO2 and H2; new hydrogen production method

Green Car Congress

The natural gas decomposition is achieved thermally only, without any addition of oxygen or water. With the process operating at very high temperatures, the innovative reactor design ensures that the correspondingly large amounts of waste heat are recycled immediately into the process.
