This project utilizes a predictive simulation framework employing LES/DNS and successfully ported models to NekRS (GPU-based) for a 10x speedup. Partners include ANL (PI), UIUC, Convergent Science Inc, and multiple National Labs. Accomplishments include validating ARC-M1 flow LES and showing that small fuel property changes significantly impact flame shape and Lean Blow Out (LBO) equivalence […]
This project advances SAF qualification by using unique instruments to measure fuel properties (surface tension, density, bulk modulus) at actual turbine engine temperatures and pressures. Partners include NREL, Georgia Tech/GE Aerospace, ANL, and Washington State University. Milestones completed include measuring critical fuel properties for simulations. Future work involves finalizing 2D GC methods and pressurized DSC.
Technological advances include a 1500-bar High Pressure Fuel Pump (HPFP) with 50% efficiency gain and high-flow injectors reducing hydraulic delay by over 50%. Partners are WM International Engineering (PI), IIT, ANL, and Diversified CPC International. All BP2 milestones were met, including successful 200-hour durability testing, system integration onto a Hyundai engine, and attaining the interim […]
This project focuses on developing a high-efficiency natural gas engine using CFD to optimize intake ports, high compression ratio pistons, and Variable Valve Timing (VVT). Cummins is the sole participant. Key achievements include demonstrating 41% Brake Thermal Efficiency (BTE) and turbine inlet temperature below the 850°C target. All Budget Period 2 milestones, including engine design […]
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 […]
