Rolls-Royce and Gulfstream test 100% SAF blend in G650 twin-jet; HEFA and SAK

Green Car Congress

The test took place on the BR725-powered Gulfstream G650 twin-jet over Gulfstream’s headquarters in Savannah, Georgia. SAF is typically a blend of a renewable synthetic paraffinic kerosene (SPK) fuel—such as HEFA—and petroleum-based Jet A fuel. Advantages of a 100% drop-in SAF. Source: Virent.

UGA study: carinata-based SAF can deliver about 65% relative carbon savings compared to conventional jet fuel

Green Car Congress

A team at yhe Universiy of Georgia has estimated the break-even price and life cycle carbon emissions of sustainable aviation fuel (SAF) derived from oil obtained from Brassica carinata—a non-edible oilseed crop—in the Southeastern United States. The total carbon emission was 918.67 1 to $1.28 1 to $0.89

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

As legislation worked its way through Congress, Jenkins’s team provided elected officials, staffers, and stakeholders with a running tally of the possible trade-offs and payoffs in emissions, jobs, and economic growth. The target of reducing emissions by 50 percent by 2030 was established through an executive order in 2021.

DOE to award up to $13M to four advanced biofuels projects

Green Car Congress

In the United States, the transportation sector accounts for two-thirds of total US oil consumption and about one-third of total anthropogenic greenhouse gas emissions. DOE is continuing to pursue the development of these renewable biofuels, with the goal of producing cost-competitive drop-in biofuels at $3 per gallon by 2017.

Agrisoma expanding partnership with Univ. of Florida on biojet fuel in US; Carinata seed

Green Car Congress

Brassica carinata (carinata) is a non-edible oilseed crop used to produce industrial oil with highly desirable fuel chemistry for ‘drop in’ aviation fuels. These studies, supported by Agrisoma, have initiated large-scale commercial production of the crop in Florida, Georgia and Alabama. and Applied Research Associates Inc.),
