Program 2: Fluidised-bed combustion of ammonia (NH3) for stationary combined heat and power generation (21.RP2.0059)

Being an excellent hydrogen (H2) carrier and effective and practical means of exporting Australia’s rich renewable energy resources, ammonia (NH3) can be used directly as a carbon-free fuel for transport or combined heat and power (CHP) generation. NH3 combustion emits no carbon oxides, sulphur oxides or particulate matter but the technical challenge is to combust NH3 efficiently with low nitrogen oxides (NOx) emission. The UWA Centre for Energy has conceptualised a fluidised-bed combustion technology using NH3 as a fuel for power generation. This project will advance the science of NH3 combustion in fluidised bed and associated NOx formation that underpin the development and deployment of fluidised-bed combustion systems for power generation using NH3 as a carbon-free fuel. By applying innovative laboratory fluidised-bed reactor experimentation and reactor modelling, the research will unravel the combustion characteristics of NH3 and mechanisms of NOx formation, which will lead to the development of new combustion systems for effective and practical use of NH3.

The project outputs will include scientific knowledge to be published in scholarly journals, new technologies to use NH3 as a fuel for power generation, and science-based advice to government and industry for informed decision making and strategic planning. The project will also build an enduring partnership and research collaboration between Australia and China in hydrogen energy and other renewable energy areas. Development of an end-use market of NH3 as a fuel for power generation will support Australia’s renewable H2 export industry and presents an opportunity for Australia to establish itself as a global leader in renewable energy export in the form of renewable NH3.
