Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

A new study on the combustion properties of biodiesel for use in urban transit buses found that using biodiesel can effectively reduce the mass of particulate matter released in both hot and cold idle modes. Depending on the feedstocks and blending ratios used to produce the fuel, variations in chemical properties may also be an issue.

Li-ion battery waste used in biodiesel production from discarded vegetable oil

Green Car Congress

Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.

Researchers use CaO catalyst to produce biodiesel/monoglyceride blend; avoiding waste glycerol

Green Car Congress

The resulting blend exhibits properties similar to conventional biodiesel, while reducing waste and improving conversion. Biodiesel is produced from vegetable oils or animal fats via a transesterification reaction with a short chain alcohol and a basic catalyst such as sodium or potassium methoxide. —Calero et al.

Researchers devise method to suppress thermal conductivity to improve thermoelectric materials for waste heat recovery

Green Car Congress

A new study published in the journal Nature Materials has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy, with potential applications such as automotive waste heat recovery.

ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. The technique is very sensitive to hydrogen atoms, making it ideal for studying water.

Hatch report finds NOVONIX dry cathode synthesis process offers cost and waste reduction improvements

Green Car Congress

a global engineering consultancy firm, has delivered its report that evaluates NOVONIX’s all-dry, zero-waste cathode synthesis process. The Hatch study found that NOVONIX’s process may potentially reduce power consumption by an estimated 25% and practically eliminate waste byproduct generation over the conventional process.
