A new lifecycle analysis by researchers at Argonne National Laboratory has found that the carbon intensity of corn ethanol has decreased 23%—from 58 to 45 gCO 2 e/MJ—from 2005 to 2019. Carbon intensity (gCO 2 e/MJ undenatured ethanol) of corn ethanol without LUC for 2005–2019. The ethanol produced in our 15?years

A study by Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon.

A newly approved standard from ASTM International’s recovered carbon black committee (D36) provides a test that will help to differentiate products and provide a quality control tool for producers and users. Recovered carbon black (rCB) is a recycled product made from end-of-life tires. This standard will improve the adoption of rCB.

An economic study by research group Steer, and commissioned by T&E, looked at future operating costs of hydrogen planes on intra-European flights and found that they could be an efficient, cost competitive technology to decarbonize the sector, provided kerosene is taxed adequately. (If GJ—approximately €0.37/L.)
