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 […]
This project develops durable fuel injection systems (FIS) and Ducted Fuel Injection (DFI) for rDME Mixing Controlled Compression Ignition (MCCI) combustion in off-road engines. A core technology advance is utilizing dual FIS development pathways to mitigate risk for a planned 200-hour durability demonstration. The technology leverages rDME’s low carbon intensity (as low as -279 gCO2e/MJ), […]
This project develops Mixing Controlled Compression Ignition (MCCI) for propane/DME blends. Technology advances include a high-pressure fuel system capable of over 1100 bar injection and CFD optimization utilizing exhaust rebreathing to stabilize combustion. The impact is achieving diesel-equivalent efficiency (≥37.1%) and enabling a potential 15% reduction in CO2 emissions compared to conventional propane engines, leveraging […]
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 […]
This R&D integrates engine experiments and catalytic decomposition to maximize ammonia utilization in 4-stroke marine engines. Technical advances include fully commissioned safety systems and demonstrating over 95% diesel replacement using dual-fuel strategies. The impact is accelerating maritime decarbonization, achieving an 85% reduction in CO2-equivalent emissions by addressing challenging fuel properties and N2O formation.
“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 […]
Inside the race between LNG, methanol, ammonia, and hydrogen — where data meets daylight and every molecule gets a second chance. Episode 1 – Four Fuels and a Vegan Burger They say the studio was once a broom closet. Now it’s home to The Upcycle Diaries, a semi-official, occasionally award-winning podcast about finding value in […]
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 […]
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 […]
