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

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

Trevor Brown October 04, 2018

"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.

DNV GL predicts carbon-neutral fuels, including ammonia, to surpass oil for shipping by 2050

Trevor Brown September 14, 2018

This week, DNV GL published its annual Energy Transition Outlook, providing a long-term forecast for global energy production and consumption, and including a dedicated report describing its Maritime Forecast to 2050. This is the first forecast from a major classification society explicitly to evaluate ammonia as a maritime fuel. By 2050, DNV GL predicts that 39% of the global shipping energy mix will consist of "carbon-neutral fuels," a category that include ammonia, hydrogen, biofuels, and other fuels produced from electricity. By 2050, these fuels will therefore have gained greater market share than oil, LNG, and battery-electric. If ammonia succeeds as the carbon-neutral fuel of choice in the shipping sector, this new demand will be roughly equivalent to 200 million tons of ammonia per year, more than today's total global production.

Pilot project: an ammonia tanker fueled by its own cargo

Trevor Brown February 22, 2018

Last month, an important new consortium in the Netherlands announced its intention to research and demonstrate "the technical feasibility and cost effectiveness of an ammonia tanker fuelled by its own cargo." This two-year project will begin with theoretical and laboratory studies, and it will conclude with a pilot-scale demonstration of zero-emission marine propulsion using ammonia fuel in either an internal combustion engine or a fuel cell.

A new strategy for internal combustion of ammonia

Stephen H. Crolius November 30, 2017

Of all the devices that can convert the chemical energy in ammonia to electricity, gas turbines and fuel cells appear to be receiving the lion’s share of development effort, outstripping that devoted to ammonia-fueled internal combustion engines (A-ICEs). An Ammonia Energy review last year found a number of organizations with histories of work on A-ICE technology, but reports of progress have not been forthcoming. It was good news, therefore, when a representative of a newly engaged group appeared at the NH3 Energy+ Topical Conference earlier this month and delivered a talk on an innovative A-ICE “combustion strategy.” Donggeun Lee from the Department of Mechanical Engineering at Seoul National University (SNU) delivered the paper, entitled “Development of new combustion strategy for internal combustion engine fueled by pure ammonia,” on behalf of his co-authors, Hyungeun Min, Hyunho Park, and Han Ho Song.

Development of New Combustion Strategy for Internal Combustion Engine Fueled By Pure Ammonia

Donggeun Lee Hyungeun Min Hyunho Park Han Ho Song

Ammonia is considered as a promising hydrogen-carrier with good storability and transportability, which, then, can be used as a carbon-free fuel as needed. However, once the ammonia is produced from the regenerative sources, it is essential to develop the energy conversion device of the chemical energy stored in ammonia into some other useful forms, e.g. electricity. Among various candidates, we focus on an internal combustion engine as energy conversion device which can be applied on automobile, power plant and etc. and can use ammonia as fuel only by simple modification. There have been many studies on the use of ammonia…

The Role of "Green" Ammonia in Decarbonising Energy Systems: Practical Demonstration and Economic Considerations

Ian Wilkinson

Ammonia has the potential to contribute significantly to the decarbonisation of energy systems, by offering a practical, carbon-free hydrogen storage and transportation vector as well as a green fuel in its own right. To better understand the prospects and challenges surrounding the use of ammonia in energy systems, Siemens is leading a collaborative project to build and test an ammonia-based energy storage system at the Rutherford Appleton Laboratory in the UK. Together with its project partners (the UK Science and Technology Facilities Council, the University of Oxford and the University of Cardiff), and supported by Innovate UK, Siemens will demonstrate…

ARPA-E talks advanced hybridization, carbon-neutral liquid fuels

Stephen H. Crolius October 26, 2017

In the race to place the automotive sector on a sustainable footing, the field is dominated by just two horses: battery-electricity and hydrogen fuel cells. The economic implementation of BEVs is already well underway, with motor companies on track in 2017 to sell more than a million vehicles globally for the first time. The economic implementation of FCVs is also in progress, albeit at a much earlier stage, and has the backing of major motor companies and public-sector agencies. Given the huge leads enjoyed by electricity and hydrogen, ammonia is scarcely seen as a contending fuel. Earlier this month, though, the U.S. Department of Energy’s ARPA-E unit published an interview with two of its program managers that has an intriguing implication: the race is far from over and ammonia may yet break to the front of the pack.

China and Australia collaborate on ammonia as a clean transport fuel

Trevor Brown October 24, 2017

The University of Western Australia has entered the increasingly competitive field of ammonia energy research in Australia, announcing a collaborative agreement to develop "the world's first practical ammonia-powered vehicle" as well as an "ammonia-based hydrogen production plant." These goals are supported by funding from the R&D arm of Shenhua Group, formerly a coal company but now "China's largest hydrogen producer with a production capacity to power 40 million fuel cell passenger cars."

The Maritime Industry Begins Assessment of Ammonia as a Fuel

Trevor Brown October 05, 2017

In the last 12 months ... The maritime industry has begun assessing ammonia as a carbon-free fuel, for internal combustion engines and fuel cells. This marks the first time since the 1960s, when NASA used ammonia to fuel the X-15 rocket plane, that industry players have seriously considered ammonia for transport applications.
