Stanford team develops efficient electrochemical cells for CO2 conversion

Green Car Congress

Scientists at Stanford University have developed electrochemical cells that convert carbon monoxide (CO) derived from CO 2 into commercially viable compounds more effectively and efficiently than existing technologies. Electrolysis must convert CO into products at a high rate with a low overall energy demand in order to be viable.

Brown Chemists Develop Process to Simplify Waste Vegetable Oil to Biodiesel Process, Chart Progress of Transesterification Reaction

Green Car Congress

Two chemists at Brown University have streamlined the conversion of waste vegetable oil (WVO) into biodiesel, eliminating the need for corrosive chemicals to perform the reactions. The reaction is complete when all of the molecules have been converted into smaller components known as fatty acid esters. WVO to Biodiesel.

Advances in the conversion efficiency of thermoelectric materials

Green Car Congress

Two separate research collaborations have recently reported advances in the efficiency of thermoelectric materials in converting heat to electricity. The high thermoelectric figure of merit is expected to enable the conversion of 14% of heat waste to electricity. at ~800 K (527 °C) by structurally modifying lead telluride.

ORNL-led team uses carbon material derived from tire waste to convert used cooking oil to biofuel

Green Car Congress

Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory (ORNL)-led research team has developed a simple method to convert used cooking oil into biofuel. The patent-pending, waste oil-to-biofuel conversion adds a new approach to waste tire recycling initiatives. —Hood et al.
