Loughborough team develops novel system to enhance SCR operation to reduce NOx further

Green Car Congress

Researchers at Loughborough University in the UK have developed a novel system that enhances SCR operation to further reduce NO x emissions and improve diesel engine efficiency. ACCT is an AdBlue conversion technology that uses waste energy to modify AdBlue to work effectively at these lower exhaust temperatures.

Study finds renewable fuels from hydrotreated vegetable oils outperform transesterified lipids and BTL from woody material in environmental lifecycle impacts and costs

Green Car Congress

However, because those feedstocks are limited, to produce larger volumes of biofuels other raw materials must also be used, Kathrin Sunde from the Norwegian University of Life Sciences and her colleagues noted in their open access paper published in the journal Energies.

ASTM approves 7th annex to D7566 sustainable jet fuel specification: HC-HEFA

Green Car Congress

This fuel pathway was the first to receive expedited review under ASTM’s D4054 “fast track” review process and benefitted from guidance from a special clearinghouse established by the US Federal Aviation Administration (FAA) to help guide SAF producers through the rigorous assessment and approval process. Feedstock(s): Syngas.

U Michigan team boosting efficiency of thermoelectric materials; potential of reaching 15-20% efficiency could result in practical applications

Green Car Congress

At that level of efficiency, TE materials become useful in practical applications such as waste heat recovery in vehicles, Kaviany noted. But we did not know what features we could manipulate to maximize the conversion of heat into electricity. Example of the structure of a partially filled CoSb skutterudite. Click to enlarge.

Study finds GHG emissions associated with palm oil production have been significantly underestimated; implications for carbon intensity of biofuels as well as biofuel policies in Europe

Green Car Congress

A new study on greenhouse gas (GHG) emissions associated with the conversion and degradation of peatland in palm oil plantations in Southeast Asia has determined that past studies have generally significantly underestimated emissions associated with palm oil grown on peatland. Southeast Asia.
