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

September 24, 2025 |

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 […]

The Digest’s Multi-Slide Guide to Indian Maritime Biofuel Landscape and Scientific Advancements

September 23, 2025 |

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 […]

The Digest’s Multi-Slide Guide to Control of Aldehyde Emissions from Alcohol-Fueled Non-Road Engines

The Digest’s Multi-Slide Guide to Control of Aldehyde Emissions from Alcohol-Fueled Non-Road Engines

September 21, 2025 |

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 […]

The Digest’s Multi-Slide Guide to Flex-Fuel Mixing Controlled Combustion Systems Enabled by Prechamber Ignition

September 16, 2025 |

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 […]

The Digest’s Multi-Slide Guide to Simultaneous GHG and Criteria Pollutants Reduction for Off-Road Powertrains

September 15, 2025 |

This project, 38% complete with $2.98M total funding, targets ≥10% GHG and ≥90% NOx reduction (<0.04 g/kW-hr) for off-road powertrains by 2025. Key future engine technologies include cylinder deactivation and high-efficiency turbochargers, showing preliminary 10% CO2 reduction. Multiple aftertreatment configurations (e.g., dual SCR, e-heater, fuel burner) are being explored. An incremental cost analysis reveals a […]
