PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Different methods for converting CO 2 into methane have long been known. —Heldebrant et al. Heldebrant, D., Kothandaraman, J., Lopez, J.S.,

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.

PCC SE and Landsvirkjun to convert silicon metal plant CO2 emissions to methanol

Green Car Congress

Landsvirkjun , The National Power Company of Iceland, and German investment company PCC SE have agreed to explore the possibility of capturing and utilizing carbon emissions from PCC’s silicon metal plant in northeast Iceland. Carbon emissions will be utilized to produce green methanol that can, for example, replace fossil fuel in ships.

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

The Swiss company Climeworks is building the world’s largest direct air capture (DAC) and storage facility for converting atmospheric CO 2 to rock in Iceland. 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.

New efficient, low-temperature catalyst for converting water and CO to hydrogen and CO2

Green Car Congress

Scientists in the US and China have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO) via the water-gas shift (WGS) reaction. Its synergy with adjacent Mo sites in α-MoC can effectively activate water at low temperature. —Yao et al.
