The Digest’s 2025 Multi-Slide Guide to Simulation of Jet Engine Performance using SAF Blends

The Digest’s 2025 Multi-Slide Guide to Simulation of Jet Engine Performance using SAF Blends

October 21, 2025 |

This research uses exascale computing (PeleLMeX solver) to perform high-fidelity simulations of combustor performance using Sustainable Aviation Fuel (SAF) blends up to 100%. A validated, reduced two-component surrogate chemical kinetic model for HEFA-SPK (74 species) was developed. This simulation capability accelerates and de-risks the expensive, risky certification of newer SAFs beyond the current 50% blend […]

The Digest’s 2025 Multi-Slide Guide to Fuel effects on aviation engine emissions – a modeling tool for SAF screening

October 20, 2025 |

This project delivers a low-computational-cost 0-D/1-D reactor network tool to rapidly screen Sustainable Aviation Fuels (SAF). The tool, validated against CFM56 engine data, incorporates reduced chemical kinetic mechanisms for fuel effects on emissions (NOx, CO, PM, PN). This technology enables fuel producers and OEMs to accelerate aviation decarbonization by de-risking new SAF candidates. The model […]

ABLC Next 2025 is here: The Morning After Groundhog Day

October 20, 2025 |

If you work in the advanced bioeconomy, you know the feeling: the alarm clock rings, Sonny and Cher start singing “I Got You Babe,” there seem to be “a thousand people freezing their butts off to worship a rat,” and there we are again — scarce feedstocks, expensive capital, Trump-policy angst, scale-up blues. It’s Groundhog […]

Turning the Darkness to Dawn: InEnTec, IEA, and the Columbia Roll On

Turning the Darkness to Dawn: InEnTec, IEA, and the Columbia Roll On

October 20, 2025 |

From hydro to hydrogen, the Columbia River keeps teaching America how to move. Editor’s Note: In 1941, Woody Guthrie wrote twenty-six songs about the Columbia River and its dams, capturing the spirit of American ingenuity at a time of transformation. Today, as the energy transition builds its next generation of projects along that same river, […]

It’s Time: Fueling a Fair Go for Rural Regions

It’s Time: Fueling a Fair Go for Rural Regions

October 16, 2025 |

  Australia’s great unspoken contract has always been simple: the country does its bit for the city, and the city returns the favor. It’s the rhythm of the fair go — a handshake across the wheatbelt and the wharf, a sense that when the work’s shared, the reward should be too. Lately, that balance’s been […]
