Ethanol sourced Carbon Dioxide and the Energy Sector

October 14, 2025 |

By Sam Rushing, President, ADVANCED CRYOGENICS, LTD. Special to The Digest In the U.S., ethanol by-product carbon dioxide, is a dominant form of CO2 off-gas from all CO2 processes and source types; and this carbon dioxide is significant in the supply to energy – related projects. This (fossil fuel) energy related sector will remain in […]

Peak Whale: Pathways to SAF, XCF Global and the Quest for Biocrude

October 13, 2025 |

“Thar’ she blows!” The cry cracked across the waves like musket fire. The decks of the Elizabeth Starbuck were slick with oil and brine, the air heavy with salt and smoke. In the dawn light off the whale-rich grounds of New Zealand, 4000 leagues sou’west of Nantucket, three boats dropped from the davits and pulled […]

The Digest’s 2025 Multi-Slide Guide to Low-Load Cycle Emission Control

October 9, 2025 |

Focused on enhancing low-temperature SCR activity for hard-to-electrify applications, this project leverages Operando EPR and DFT calculations to study Cu-zeolite kinetics. A key finding is that strong Brönsted acid sites (BAS) enhance low-temperature activity by promoting the hydrolysis and transfer of Cu(II) complexes. The team validated that NH3 overdosing inhibits NOx conversion by hindering the […]

This project uses atomic-level insights (HAADF-STEM) to understand catalyst durability against biodiesel poisoning and H2-ICE exhaust. Technologically, highly stable Pd-core Pt/Pd-shell structures were identified in commercial catalysts for oxidation. Key findings show high H2O content increases low-temperature SCR N2O formation, while H2 slip reduces redox-active Cu(II) sites above $200C. H2-SCR concepts are advancing to significantly […]

October 7, 2025 |

This research fundamentally clarifies N2O formation mechanisms during low-temperature SCR using Cu-zeolite catalysts and advanced characterization (DRIFTS/EPR). Key findings indicate that N2O formation is driven by the gaseous NO2 pool and that Brönsted acid sites (BAS) catalyze NH4NO3 decomposition. This work supports advanced technological solutions, demonstrating that a multi-component catalyst bed arrangement (Fe-CHA and composite […]

From Pearl Harbor’s smoke to the IMO’s clock, the maritime world faces its most decisive refueling mission since 1942. “The next Guadalcanal of this campaign won’t be a battle at sea — it will be a price curve, a port standard, a policy vote.” It began in smoke. Pearl Harbor, December 7th, 1941. The harbor […]
