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