New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

Electrolysis offers an attractive route to upgrade greenhouse gases such as carbon dioxide (CO 2 ) to valuable fuels and feedstocks; however, productivity is often limited by gas diffusion through a liquid electrolyte to the surface of the catalyst. Resources. 15) with an ethylene partial current density of 1.3 Science Vol.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. For the latter, two main contributions are distinguished: gas depletion due to CO 2 consumption and ion generation in areas close to the electrocatalyst surface. —Soto et al.

Berkeley Lab team validates bio-analogous technique for converting CO2 into liquid acetate

Green Car Congress

For one experiment, Yang and team designed a model device with a copper surface; then, they exposed the copper surface to liquid methyl iodide (CH 3 I) and CO gas, and applied an electrical bias to the system. The researchers then designed another model device, this time layered with the nanoparticle thin material.

DOE launches Clean Fuels & Products Shot

Green Car Congress

The US Department of Energy (DOE) launched the Clean Fuels & Products Shot , a new initiative that aims to reduce greenhouse gas emissions (GHGs) from carbon-based fuels and products significantly. Biomass and waste conversion technologies designed to use green electricity and hydrogen to maximize carbon retention in products.
