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

Green Car Congress

estimated that with conversion by hydrothermal liquefaction (HTL) and upgrading, the wet waste resource availability in the United States could be converted to jet fuel that is equivalent to about 24% of the U.S. The life-cycle greenhouse gas (GHG) emissions of the two pathways were 11.2 Skaggs et al. demand in 2016. 1c06561.

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. EH&E) and Adjunct Professor of Environmental Health at Harvard’s T.H. gCO 2 e/MJ (range of 37.6

S&P Global: More than 75% of oil and gas production in US Gulf of Mexico has lower than average greenhouse gas intensity

Green Car Congress

More than three-fourths of all oil and gas production in the US Gulf of Mexico has a lower greenhouse gas (GHG) intensity than the basin-wide average, according to a new S&P Global Commodity Insights analysis. For comparison, the GHG intensity range for 99% total 2021 production across the North Sea study area extends to c.

Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced. Conversion of iron ore into iron accounts for 90% of steelmaking emissions that may be eliminated using Electra’s process.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.
