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 […]
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 […]
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 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 […]
India targets net-zero emissions for its shipping sector by 2070 and major ports by 2047. The 2022 marine fuel consumption was 1.24 million tonnes, projected to reach 1.43 million tonnes by 2030. Biofuel blend trials (B20-B50) showed 80-90% CO2 emission reductions. India’s bio-economy grew 16-fold to $165.7 billion by 2024. New guidelines permit biofuels, with […]
This $3.27M project, ending December 2024, aims to demonstrate a Near-Zero Emissions Concept via an integrated engine and aftertreatment simulation platform in GT-SUITE. Key achievements include calibrating an ORNL SCR model for catalyst aging (up to 500h aging data), and reducing computational cost for Urea-Water Solution (UWS) spray modeling to ~2000 CPU hours/second by using […]
This FY22-FY25 project, with $400k in FY24 funding, addresses toxic aldehyde emissions from low-lifecycle carbon fuels (LLCFs) in off-road engines. Alcohols like methanol and ethanol form less reactive aldehydes during oxidation. Stable formaldehyde delivery for experiments was achieved. In-situ DRIFTS analysis reveals highly stable formates/acetates on catalyst surfaces inhibit further oxidation, underscoring the critical need […]
This project, 35% complete with $3.8M total funding, is electrifying Articulated Dump Trucks (ADT) to reduce ~78% idling time, targeting over 20% fuel savings and 10,000+ metric tons GHG reduction. Dynamic System Modeling (DSM) predicts >12,000 hours battery life (project objective: 15,000 hours). Lab-scale 10kW soft-switched SiC inverters have been developed and tested at 50kHz. […]
This 50% complete project, with $2.99M total funding, aims to electrify Compact Track Loaders via Hybrid Hydraulic-Electric Architecture (HHEA). The objective is to reduce electricity usage by 40% and GHG footprint by 80%, leveraging off-the-shelf components. Simulations predict 31.78% to 42.50% overall energy savings, extending a 75kWh battery’s life by up to 74%. A fast-switching […]
This 60% complete project, funded at $3.125M, is developing a heavy-duty flex-fuel (E10-E98) engine with prechamber ignition to mimic diesel combustion. This approach promises ~50% reduction in lifecycle CO2 using bioethanol, maintaining snap torque and efficiency. Experimental results with E98 fuel demonstrate robust “diesel-like” performance, lower NOx, and “zero” soot compared to conventional diesel. The […]
