ORNL team develops carbon-nanotube-based superlubricity coating

Green Car Congress

Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a coating composed of carbon nanotubes that imparts superlubricity to sliding parts. In comparison, when dry metals slide past each other, the coefficient of friction is around 0.5. We tried it without oil; it didn’t work. Kumara et al.

Review of co-processing of biocrudes in oil refineries

Green Car Congress

Liquid intermediates from pyrolysis and hydrothermal liquefaction (HTL) can be co-processed in an oil refinery along with conventional crude oil. After pyrolysis, the vapors are condensed to give a dark brown fast pyrolysis bio-oil (FPBO). In fast pyrolysis, biomass is quickly heated to around 500 °C in the absence of oxygen.

Goodyear unveils 90% sustainable-material demonstration tire, approved for road use

Green Car Congress

A sustainable material is defined as a bio-based/renewable, recycled material or one that may be produced using or contributing to other sustainable practices for resource conservation and/or emissions reductions including mass-balance materials. Today, eight product lines, and some racing tires, include soybean oil.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Our analysis assumes that captured carbon dioxide can be stored indefinitely, an optimistic and unproven assumption. Energy Sci Eng.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.

Study concludes permanent loss of peatlands in open-pit oil sands mining adds significantly to carbon burden of oil sands production

Green Car Congress

Researchers at the University of Alberta (Canada) have quantified the transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. million metric tons of stored carbon. Converting from units of carbon to CO 2 equivalents, this is between 41.8

DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Meanwhile, wet waste feedstocks, such as animal manure and fats, oils, and greases (FOG), represent another important category of resources that could be utilized to produce MCCI bioblendstocks due to its abundant availability.
