Safe and Effective? New Study Evaluates Ammonia as a Marine Fuel

Stephen H. Crolius August 07, 2019

In mid-June the Dutch naval architecture firm C-Job released "Safe and effective application of ammonia as a marine fuel," a thesis written by the firm’s Lead Naval Architect Niels de Vries for the Marine Technology Master of Science program at the Delft University of Technology in the Netherlands. While the thesis delivers an extensive assessment of ammonia's potential effectiveness as a marine fuel, it breaks new ground in its consideration of ammonia's safety in this context.

Strategic collaboration announced between Proton Ventures and Duiker Combustion Engineers

Trevor Brown August 01, 2019

This week, two industry members of the Ammonia Energy Association announced that they have launched a "strategic collaboration." Coming from opposite ends of the ammonia energy value chain, one specialized in production and the other in combustion, this new partnership allows the two companies to "complete the chain of using ammonia as an energy solution."

Fuel Economy Standards, and the Roles of Ammonia

James Grieve July 31, 2019

In the news this week, California and four automakers (BMW, Ford, Honda and VW) signed an agreement on fuel economy standards, rising 3.7% per year to about 50 MPG in 2026. This agreement, as well as previous California and Federal standards, give automakers flexibility to meet the standards with incentives and credits for new technology such as electric, hybrid, and alternative fuel vehicles.

Heavy-duty diesel trucks to be converted to use ammonia fuel in Canada

Trevor Brown June 20, 2019

This week, Hydrofuel Inc announced a commercial demonstration project to convert diesel gensets and transport trucks to run on ammonia fuel, with the conversion work and dual-fuel operations scheduled for a three year period. The CAD $2 million (USD $1.5 million) project will take place at TFX International, in Toronto, and involves the conversion of four existing diesel-fueled assets: two stationary power generators and two transport trucks. These will be converted using Hydrofuel's "aftermarket multi-fuels engine retrofit systems," and they will thereafter be able to operate on a dual fuel basis.

Dutch Company Breaks New Ground in Ammonia Combustion

Stephen H. Crolius April 04, 2019

Earlier this year the Dutch company Duiker Combustion Engineers shared a company paper with Ammonia Energy that targets ammonia energy as an application for the company’s proprietary stoichiometry-controlled oxidation (SCO) technology.  The technology’s original commercial deployment in petroleum refining occurred in 2010, and now the company sees potentially broad applications for it as a sustainable energy expedient in the industrial and electricity sectors.

MAN Energy Solutions: an ammonia engine for the maritime sector

Trevor Brown January 25, 2019

In June 2018, MAN Diesel & Turbo rebranded itself MAN Energy Solutions, reflecting the maritime engine market leader's "strategic and technological transformation" towards sustainability. The company was "taking a stand for the Paris Climate Agreement and the global pursuit of a carbon-neutral economy." According to Uwe Lauber, Chairman of the Board, "our activities have a significant impact on the global economy. In shipping, for example, we move more than half of the global stream of goods ... [and] the path to decarbonising the maritime economy starts with fuel decarbonisation, especially in container shipping." This week, the company took a significant step towards realizing its vision, disclosing that it is "pressing ahead with developing ... an ammonia-fuelled engine." This builds on the technology development pathway that MAN ES presented at the NH3 Energy+ Topical Conference at Pittsburgh in October 2018. The budget and timeline are set: the €5 million (USD$5.7 million) project will last two to three years and, if the shipowners decide to deploy the finished product, "the first ammonia engine could then be in operation by early 2022."

Exploring ammonia's potential as a marine fuel

Niels de Vries

International shipping is responsible for approximately 90% of the world trade. Looking to the relative emissions, in gram CO2 per ton km, maritime transport score significantly better compared to others like rail, road and airfreight. However, since most of the transport is done by ships the absolute contribution of greenhouse gases (GHG) by the maritime industry is clearly visible. Of all the global emissions the maritime industry is responsible for 3% CO2, 13% SOx, and 15% NOx. To reduce SOx and NOx several regulations are either upcoming or already in play. Current regulations require the sulphur emissions to be less…

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

David ToyneJay Schmuecker

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.
