EPRI, GTI Launch Low-Carbon Initiative

Stephen H. Crolius September 03, 2020

Last month the Electric Power Research Institute (EPRI) and the Gas Technology Institute (GTI) announced a new undertaking: the Low-Carbon Resources Initiative (LCRI). According to the organizations’ press release, over the next five years they will work together and with

Improved Method of Using Hydrogen and Ammonia Fuels for an Internal Combustion Engine

David ToyneJay Schmuecker December 14, 2018

A tractor mounted internal combustion engine is fueled by Hydrogen or a combination of Hydrogen and Ammonia. Developments of an improved method of fuel injection and ignition control. Hydrogen is port injected in the intake manifold, and liquid ammonia is injected in the throttle body. A dual fuel ECU, Engine Control Unit, controls the fuel mixtures and the firing of multiple coils for ignition. The paper will address significant engine performance improvements and the resulting fuel consumption and engine emissions levels.

Ammonia-Hydrogen Power for Combustion Engines

Agustin Valera-MedinaPhil BowenDaniel Pugh October 31, 2018

Ammonia blends can potentially become a breakthrough chemical for power generation, cooling storage and distribution of energy. Gas turbines and internal combustion engines are potential candidates for the use of the resource in an efficient way that will enable commissioning of combined cycles to power communities around Europe and around the world while serving as sources of heat and chemical storage. Therefore, development of these systems will bring to the market a safer, zero carbon fuel that can be used for multiple purposes, thus decentralizing power generation and increasing sustainability in the communities of the future whilst positioning the developing…

Efficient and Clean Combustion of Ammonia-Hydrogen-Air Mixtures

Hadi NozariArif Karabeyoğlu November 1, 2017

Based on its well-known merits ammonia has been gaining special attention as a potential renewable energy carrier which can be replaced in power generation systems. Considering its low flame speed and its potential for producing fuel NOx as the main challenges of combusting ammonia, flame stability, combustion efficiency, and NOx formation are experimentally investigated. Focus is on premixed ammonia-hydrogen-air flames with high mixture fractions of ammonia (60-90% by volume) under standard temperature and pressure conditions. We introduce silicon-carbide (SiC) porous block as a practical and effective medium for ammonia-hydrogen-air flame stabilization which enables stable and efficient combustion of the mixtures…

A Hybrid Vehicle Powered by Hydrogen and Ammonia

Paolo DarioRoberto GentiliNeri BonfantiGiuseppe PozzanaStefano FrigoNicolo DoveriVirgilio MattoliMarina Ragnoli September 24, 2013

A partnership of Research and Industry entities has developed a fully working hybrid electric vehicle equipped with a 15 kW IC engine fuelled with liquid ammonia as a range extender of the lithium batteries pack on board. The entire vehicle powertrain (ie, the IC engine, the electric generator coupled with the engine, the electric motor, the electronics etc.) has been studied and designed. Regarding the IC engine, as is known, ammonia combustion is characterized by a high activation energy and a low flame velocity, therefore a small amount of hydrogen is requested as igniter and combustion promoter. The necessary amount…
