Study finds carbon emissions benefits of reduction in oil demand depend on size of drop and global oil market structure

Green Car Congress

New research led by Mohammad Masnadi, assistant professor of chemical and petroleum engineering at the University of Pittsburgh Swanson School of Engineering, offers a closer look at the relationship between decreasing demand for oil and a resilient, varied oil market—and the carbon footprint associated with both.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions. Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 —Miettinen et al.

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. With an oil lubricant, the coefficient of friction falls to about 0.1. The carbon nanotubes are destroyed in the rubbing but become a new thing. Kumara et al.

T&E study finds EU has replaced Russian oil barrel-for-barrel as continent fails to cut demand

Green Car Congress

Since the EU imposed sanctions on Russia in the wake of the invasion of Ukraine, there has been a redrawing of the global oil map, a new study by Transport & Environment (T&E) shows. Instead of cutting demand, Europe has simply replaced imports from Russia with oil from other producing countries. C carbon budget.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Ricardo study finds electric and hybrid cars have a higher carbon footprint during production than conventional vehicles, but still offer a lower footprint over the full life cycle

Green Car Congress

For a battery EV, 46% of its total carbon footprint is generated at the factory, before it has travelled a single mile. The study found that some of the CO 2 savings made during the use of low carbon vehicles is offset by increased emissions created during their production, and to a lesser extent, disposal. Estimated lifecycle.

Study suggests microbe produces methane from crude oil all by itself

Green Car Congress

Crude oil and gas naturally escape from the seabed in many places known as seeps. This microbe, an archaeon named Methanoliparia , transforms the hydrocarbons by a process called alkane disproportionation: it splits the oil into methane (CH 4) and carbon dioxide (CO 2 ). © Max Planck Institute for Marine Microbiology).
