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. An open-access paper on their results is published in the journal ACS Sustainable Chemistry & Engineering.

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.

DOE to award up to $6.7M to projects to convert captured CO2 to useful products, including fuels

Green Car Congress

DOE’s Office of Fossil Energy is seeking these projects as part of the Department’s Carbon Storage program, which has the goal of developing and advancing technologies to improve the effectiveness of carbon storage, reduce the cost of implementation, and be ready for widespread commercial deployment in the 2025–2035 timeframe.

Study finds renewable fuels from hydrotreated vegetable oils outperform transesterified lipids and BTL from woody material in environmental lifecycle impacts and costs

Green Car Congress

GHG emission comparison between fossil diesel, transesterified lipids, HVO and woody BTL. If HVO is produced from waste feedstocks with low upstream impacts, the high conversion efficiency of the HVO production process will make HVO the preferred fuel to BTL from any woody feedstock, even woody waste.

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

Green Car Congress

Because the use of natural gas for transportation requires compressing, liquefying, or conversion, it is important to determine the best use of natural gas as a transportation fuel. Cost considerations on the total infrastructure or cost of ownership were also outside the scope of this work but are nevertheless important, they team noted.

The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. The first was the American NS Savannah , built in the late 1950s at a cost of $46.9 We needed to get the conversation started.” Cost also played a big role in NuScale Power Corp.’s million (an eye-popping $495 million today).
