Fuel Economy Standards, and the Roles of Ammonia
Article

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
Article

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
Article

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
Article

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
Presentation

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
Presentation

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.

Ship Operation Using LPG and Ammonia As Fuel on MAN B&W Dual Fuel ME-LGIP Engines
Presentation

LPG has been used as fuel in the car industry for many years and now, with Exmar and Statoil’s orders for ocean-going ships fitted with the dual fuel ME-LGIP engine, LPG will be used on marine engines as well. The new engine series is currently being developed to match all types of bigger merchant ships. This order was made in consequence of the new 2020 0.5% sulphur fuel cap, but this step forward has not stopped the discussion and interest in lowering CO2, NOx, SOx and particulate emissions even further. On the contrary, it has actually been further fuelled by…

Ammonia for Power: a literature review
Article

"Ammonia for Power" is an open-access literature review that includes over 300 citations for recent and ongoing research in the use of ammonia in engines, fuel cells, and turbines, as well as providing references to decades of historical case studies and publications. The review, written by a consortium of ammonia energy experts from the University of Cardiff, University of Oxford, the UK's Science and Technology Facilities Council, and Tsinghua University in China, can be found in the November 2018 edition of Progress in Energy and Combustion Science.
