WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. The results are reported in an open-access paper in the journal Communications Biology.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

This article proposes a model that accounts for the modes in which aqueous gas depletion evolves over time and affects the long-term CO 2 electroreduction and the corresponding pH evolution near the electrode’s surface. pH is then suggested as an accurate and indirect means to measure CO 2 concentration in a liquid electrolyte.

Liquid Light unveils cost-advantaged catalytic process to make chemicals from CO2

Green Car Congress

Liquid Light unveiled its new process for the production of major chemicals from carbon dioxide, showcasing its demonstration-scale “reaction cell” and confirming the potential for cost-advantaged process economics. Other processes require an estimated $617 to $1,113 of feedstocks derived from oil, natural gas or corn.

EPA trends report finds MY 2021 fuel economy remained flat at a record high while CO2 levels hit new low

Green Car Congress

The report also shows all 14 large automotive manufacturers achieved compliance with the Light-duty Greenhouse Gas (GHG) standards through at least MY2020. The combined category of electric vehicles (EVs), plug-in hybrid electric vehicles (PHEVs), and fuel cell vehicles (FCVs) increased to 4% of nationwide production in MY 2021.

Light over heat: UV-driven rhodium nanoparticles catalyze conversion of CO2 to methane

Green Car Congress

Duke University researchers have engineered rhodium nanoparticles that can harness the energy in ultraviolet light and use it to catalyze the conversion of carbon dioxide to methane, a key building block for many types of fuels. The red corners of the cube show the intense electric field from the excitation of LSPRs. Zhang 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.
