The Digest’s 2025 Multi-Slide Guide to Low Greenhouse Gas NOx Control

October 7, 2025 | Jim Lane

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 […]

The Digest’s 2025 Multi-Slide Guide to Optimized Low Carbon Fuel Range Extenders (HiREX)

All Budget Period 2 milestones, including engine design […]

The Digest’s 2025 Multi-Slide Guide to Integrated Simulation of HD Diesel RDE

September 29, 2025 | Jim Lane

This project developed and validated CFD and 1D/2D/3D aftertreatment models, integrating them into GT-Suite using a new QSExplicit solver approach to simulate heavy-duty real driving emissions. Partners include WVU, ANL, ORNL, Gamma Technology, Convergent Science Inc, and Navistar. Key milestones achieved include 100% completion of Budget Period 1 (BP1) and preliminary integration of 1D engine […]

The Digest’s Multi-Slide Guide to Asia Biobunkers Pricing and Market Update

September 28, 2025 | Jim Lane

Singapore has surpassed Rotterdam as Asia’s largest biobunkering hub since 2024, driven by tightening IMO and EU regulations. The IMO Carbon Intensity Indicator (CII) mandates 4-17% GHG reduction by 2028, and GHG pricing begins in 2028 ($100/tCO2e for Tier 1 units). Singapore’s biodiesel demand from bio-bunkers is projected to reach ~1.4 million metric tons by […]

The Digest’s Multi-Slide Guide to Lowering Barriers for Maritime Biofuels

September 25, 2025 | Jim Lane

Green Corridors as key demonstration platforms for maritime biofuel adoption. New MARPOL Annex VI will mandate GHG intensity reductions and economic incentives. DNV’s scenario projects bio-methanol and bio-MGO dominance. Maersk has invested $100M in a green methanol plant aiming for 500,000 metric tons/year production and added 18 dual-fuel vessels to its fleet. Wind-assisted propulsion is […]

The Digest’s Multi-Slide Guide to Global Regulatory Framework and Policies for International Shipping

September 24, 2025 | Jim Lane

The 2023 IMO GHG Strategy aims for net-zero emissions from international shipping by or around 2050, targeting 20% GHG reduction by 2030 (striving for 30%) and 70% by 2040 (striving for 80%). A mandatory GHG emissions pricing mechanism will apply from 2028 to ships >5,000 tons. The IMO forecasts a need for 25-30 MTOE of […]
