Panel 1: Hydrogen and power-to-ammonia

Circular Ammonia-Hydrogen Enabled by Plasma-Catalysis Dr. Sylvain Coulombe

With its high hydrogen content, ammonia is increasingly seen as a scalable carbon-free energy carrier for hard to decarbonize sectors such as long-haul transport and industrial heating. As electricity becomes a wider-spread energy commodity and the pressure for carbon emissions reduction increases, there are strong incentives for the development of all-electric ammonia-hydrogen conversion processes. In contrast to the established ammonia synthesis industry which relies on large-scale concentrated plants, the more geographically distributed and equitable access to renewable electricity calls for downsized processes and plants, on-demand generation and use, and scalability through parallelization. Similarly, there are opportunities for the agriculture sector for onsite ammonia-based fertilizer production where renewable electricity is available. Plasma, the fourth state of matter, is an energetic chemical processing environment sustained entirely by electricity and enabling reaction conditions not achievable via standard thermochemistry. In the context of gas conversion, the plasma can be used for the dry and environment-friendly synthesis and regeneration of catalysts as well as the synthesis and recycling of energy vectors such as hydrogen and ammonia. In this short talk, I will introduce key concepts of plasma chemistry, catalyst synthesis and regeneration, and outline the state-of-the-art in plasma-catalytic processing of ammonia and hydrogen.

Design and analysis of power-to-ammonia  Dr. XiaoYu Wu

 Ammonia is a versatile chemical that is distributed and traded widely as a commodity for the fertilizer and refrigeration industries, and it also has the potential to be a low-emission fuel, hydrogen carrier and energy storage medium. Converting clean electricity to ammonia (i.e., power-to-ammonia, or P2A) is a critical process to decarbonize the use of ammonia in agriculture, transportation, and energy sectors. In this talk, I will highlight the research activities in my group on P2A processes. We designed a P2A plant using offshore wind power from Sable Island, Nova Scotia and conducted a techno-economic analysis to study electrified ammonia production. The levelized cost of ammonia was found to be highly dependent on the electrolyzer efficiency and capacity factor. Even though the offshore wind farms in Atlantic Canada are expected to have high-capacity factors, we still found it necessary to connect the plant with the electrical grid to maintain high ammonia outputs. Yet grid-connection could raise the carbon intensities of the P2A process to a higher level than the conventional fossil-fuel based ammonia production.

Electrooxidation of urea and ammonia for wastewater treatment | Dr. Anna Klinkova

The growing human population is closely connected to the increasing agricultural demands for fertilizers containing urea and ammonia. As a result, large amounts of wastewater enriched with urea and ammonia are released to the environment from the agricultural runoff and the industrial plants producing urea- and ammonia-based fertilizers. If left untreated, this nitrogenous waste decomposes into nitrogen oxides, which play a major role in causing respiratory diseases, cancer, acid rain, smog, and contribute to the destruction of fragile ecosystems by enhancing cyanobacteria algae blooms. Electrooxidation of urea and/or ammonia provides a route to treat the wastewater containing these compounds, while simultaneously producing value-added products.

Panel 3: Technology development

Adaptive approach for high-entropy alloy catalysts in ammonia decomposition | Dr. Conrard G. Tetsassi Feugmo

Hydrogen-based technologies, including fuel cells and hydrogen-powered vehicles, require efficient and cost-effective hydrogen storage materials. To address this challenge, we propose a computationally driven adaptive design approach for the development of high-entropy alloy catalysts that can efficiently decompose ammonia acting as hydrogen carriers. Our approach utilizes artificial intelligence (AI) and density functional theory (DFT) methods to generate a dataset of high-entropy alloy catalysts and predict their catalytic performance. Through machine learning algorithms, we identify several promising catalysts with improved performance compared to existing ones. We also examine the underlying mechanisms using DFT calculations. Our study suggests that these catalysts have the potential for use as efficient hydrogen carriers, offering a framework for the development of advanced materials in various applications. AI and DFT methods demonstrate potential for the adaptive design of high-performance catalysts.

Ammonia as an Alternative Fuel for Diesel Engines – Potential Benefits and Technical Barriers      Dr. Hongsheng Guo

 Compression ignition diesel engines dominate the power generation in freight transportation industry, such as marine, mining, rail, construction, and heavy-duty ground transportation. Electrification of these engines is a major challenge due to the limited energy densities of current batteries. Fuel switching and efficiency improvement are two effective ways to reduce greenhouse gas emissions from such engines. Hydrogen is a zero-carbon energy carrier, and ammonia (NH3) is a hydrogen carrier that is easier to store and transport compared to hydrogen itself. Replacing diesel by NH3 in diesel engines has potential to help reduce both CO2 and PM emissions. This presentation will discuss the potential benefits and technical barriers of ammonia as an alternative fuel for heavy-duty diesel engines.
