Israeli company reports successful stage 1 testing of solar CO2-to-fuels technology

Green Car Congress

Israel-based NewCO2Fuels (NCF), a subsidiary of GreenEarth Energy Limited in Australia, reported completion of stage 1 testing of its proof-of-concept system for the conversion of CO 2 into fuels using solar energy. Driving the system using a solar-based heat source (100% renewable). Concept of the NCF process. Click to enlarge.

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Conducive to our new solar process, electrolysis of molten carbonates forms oxides, which precipitate as calcium oxide when mixed with calcium carbonate. Click to enlarge. —Licht et al.

Researchers demonstrate efficient electrochemical reduction of CO2 to C2+ alcohols

Green Car Congress

Here, we demonstrated a rational strategy to synthesize the Cu catalyst under a CO-rich environment to induce the growth of defect-rich sites that are best for the adsorption of CO. A and B) Cu-DS catalyst synthesized under a CO-rich environment favors high coverage of *CO intermediate and promotes alcohol production. (D

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. We hope that it can be a steppingstone for future sustainable solar fuel production.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

For the current study, Toma and her team designed a model solar fuels device known as a photoelectrochemical (PEC) cell made of copper(I) oxide or cuprous oxide (Cu 2 O), a promising artificial photosynthesis material. We knew it was unstable—but we were surprised to learn just how unstable it really is. —Francesca Toma.
