A Comprehensive Review on the Hydrogen–Natural Gas–Diesel Tri-Fuel Engine Exhaust Emissions

Energies, Journal Year: 2024, Volume and Issue: 17(15), P. 3862 - 3862

Published: Aug. 5, 2024

Natural gas (NG) is favored for transportation due to its availability and lower CO2 emissions than fossil fuels, despite drawbacks like poor lean combustion ability slow burning. According a few recent studies, using hydrogen (H2) alongside NG diesel in Tri-fuel mode addresses these while enhancing efficiency reducing emissions, making it promising option engines. Due the importance novelty of this, continuation ongoing research, insufficient literature studies on HNG–diesel engine that are considered helpful researchers, this research has been conducted. This review summarizes engines utilizing hydrogen-enriched natural (HNG). The methodology involved summarizing effect design, operating conditions, fuel mixing ratios supplying techniques CO, CO2, NOx HC separately. Previous show with increases CO decreasing compared pure diesel. However, reduces but NOx. On other hand, effectively mitigates disadvantages fuels separately, resulting decreased HC, inclusion improves efficiency, ignition delay, enhances heat release in-cylinder pressure. Additionally, operational parameters such as power, speed, load, air–fuel ratio, compression injection directly affect Overall, approach offers benefits or separately dual-fuels.

Experimental investigation on hydrogen-rich syngas production via gasification of common wood pellet in Bangladesh: Optimization, mathematical modeling, and techno-econo-environmental feasibility studies

Biomass Conversion and Biorefinery, Journal Year: 2024, Volume and Issue: unknown

Published: June 28, 2024

Abstract Since hydrogen produces no emissions, there is increasing interest in its production throughout the world as need for clean and sustainable energy grows. Bangladesh has an abundance of biomass, particularly wood pellets, which presents a huge opportunity gasification to produce hydrogen. Gasification mahogany ( Swietenia mahagoni - SM) mango Mangifera indica- MI) performed downdraft gasifier evaluate impact particle size, equivalence ratio, temperature on gas composition performance. Under optimal conditions determined by central composite design-response surface methodology (CCD-RSM) optimization, SM MI can greatly increase yield cold efficiency, offering workable, environmentally friendly, long-term solution Bangladesh's shortage pollution problems. Through RSM analysis best operating include feed size 22.5 mm, ratio 0.34, 1176 K, where total 11.2% was obtained. In case gasification, optimum condition found at 1132.47 12.85% The economic study provides LCOE 0.1116 $/kWh, project payback period be 10.7 years. By reusing waste from nearby sawmills, this helps manage sustainably lowering levels deforestation. It also highlights wider sustainability effects assisting international initiatives fight climate change advance independence.

Emission Characteristics of Hydrogen-Enriched Gasoline Under Dynamic Driving Conditions

Energies, Journal Year: 2025, Volume and Issue: 18(5), P. 1190 - 1190

Published: Feb. 28, 2025

This paper investigates the emission characteristics of hydrogen-enriched gasoline (95G5H2) under dynamic driving situations in order to fulfill growing need for cleaner and more efficient automobile fuels. study aimed investigate impact hydrogen addition on pollutant-specific emissions, including CO, CO2, HC, NOx, using a Nissan Qashqai that ran both pure (100G) 95G5H2. Emission statistics were obtained by computer simulations Worldwide Harmonized Light Vehicles Test Cycle (WLTC) applied AVL CRUISE software. The presents method comparing pollutants emitted combustion engine when powered regular fuel with hydrogen. tests performed real conditions, presented shows amount vehicle is directly motion, which allows effective comparison different 95G5H2 sharply reduces CO-, CO2-, HC-specific emissions 22.19%, 14.55%, 35.46%, respectively, compared 100G. However, NOx-specific increased 20.17%, suggesting compromise between higher efficiency burning temperatures. performs better urban cycles, plenty acceleration deceleration, usually results incomplete combustion. Although additional refinement needed cut demonstrate fuels have considerable potential lower vehicle-specific emissions. significant conclusions advantages fuels, practically environmentally, will help future development environmentally friendly transportation solutions.
