EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

The use of heavy fuel oils (HFOs) contributes to global warming due to the fossil origin of these fuels and, moreover, generating non-negligible emissions of pollutants such as sulfur oxides. However, HFOs are banned in the national waters of many countries. The participants are Vertoro B.V. (NL); NL); Winterthur Gas & Diesel Ltd. (CH);

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures. Compared to other water use sectors (e.g. A study published in Nature Climate Change suggests that thermoelectric power plants (i.e.,

New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water. —Yong Wang.

Lifecycle study explores production of NdFeB rare-earth magnets from primary production and recycling pathways

Green Car Congress

The choice of recycling technology is also important with respect to resource recovery, the study by a team from the Netherland and the UK found. Additionally, human toxicity is significantly lower, because this recycling process does not include the most polluting processing steps associated with virgin production.
