Development and Application of Functional Materials for Next-Generation Electrochemical Energy Storage Technologies


With advances in electrification in transportation, extensive use of power electronics, and utilization of renewable energy and their assimilation into the electrical grid, there is a clear need to develop high-performance, safer, and more sustainable energy storage technologies for the emerging applications. My group is interested in developing and applying new materials in electrochemical energy storage technologies such as next-generation Li-ion, Li metal, Na-ion, and solid-state batteries. In my talk, I will first cover the development of electrode materials for next-generation Li-ion batteries to illustrate our understanding of the structure-property relationship for its excellent energy density and cycling stability. Second, I will present approaches to developing high-performance solid-state batteries, including synthesizing highly conductive solid-state electrolytes, designing and architecting stable interphases on electrode materials using electrochemically active interfacial materials, and fabricating low-cost cathode materials, potentially for electric vehicle and stationary energy storage applications. Together, I would like to demonstrate the research effort aiming to build our knowledge, expertise, and understanding of critical electrochemical processes and mechanisms to employ desired features in electrochemical energy storage systems to meet the requirement of new energy applications.

Investigations on Cogeneration and Waste Heat Recovery via Thermoelectric Generators


A thermoelectric generator (TEG) is a semiconductor device, which achieves a direct conversion of heat in to electrical energy. The electric power produced by a TEG is strongly influenced by the applied heat sink. While a TEG is aimed at harvesting waste heat, the optimization of the efficiency of the heat sink is a key task for the design of waste heat recovery systems implementing TEG. A TEG model is proposed and implemented in an open source toolbox for field operation and manipulation (OpenFOAM) for the purpose of performing optimizations of the heat sink, using a commercially available TEG as basis. This model includes the multi-physics thermoelectric coupled effects. Conservation principles of energy and current are considered simultaneously. This includes the thermal and electric conduction, Seebeck effect, Peltier effect, Thomson effect, and Joule heating. Much attention is paid to model validation. On the one hand, different modelling aspects are validated based on the measurements from the literature. On the other hand, specialized experiments are performed on an in-house test rig, which is developed to this purpose. Within this framework, aspects are explored, which have not been investigated in detail before, including the effect of variable temperature patterns.

Based on the models, TEG applications are presented, which aim the utilization of waste heat from a forging process and cogeneration from the abundantly available heat released by biomass combustion. Optimization procedures are additionally utilized in designing the corresponding cooling systems.

Direct Air Capture of CO2 and Its Use for Synthetic Aviation Fuels: The Promise of Greener Skies


Globally, there are currently 27 Direct Air Capture (DAC) facilities that have been established. Out of these facilities, 18 have been completed, while 130 are still in the process of development. According to the International Energy Agency (IEA), all of these facilities are relatively small-scale, but together, they can remove approximately 11,000 tons of CO2 annually. DAC technology can help mitigate difficult-to-avoid annual emissions from concrete (about 8%), transportation (about 24%), the iron-steel industry (about 11%), and wildfires (about 0.8%).

In my presentation, I will discuss the current state of commercial DAC technologies and the five essential pillars of technology required in the process. These include capture technologies, energy demand, final costs, environmental impacts, and political support. I will explain the processing steps for liquid and solid carbon capture technologies and highlight their specific energy requirements. Additionally, I will delve into the capital and operational costs of DAC, including the plant power energy sources, land, and water needs. Lastly, I will discuss a possible scenario for using captured CO2, where CO2 captured from the air can be used as a climate-neutral raw material for synthetic aviation fuels.

Prospects in Global Vehicle Electrification Over the Next Decade


Policy makers worldwide are under pressure for achieving decarbonization towards net zero emissions by the year 2050, and maintain a global average temperature increase below 1.5C per the special report by the intergovernmental Panel on Climate Change (IPCC). Decarbonization of the global electricity sector can be achieved via deploying of a variety of technologies, ranging from renewable power sources like wind, geothermal and solar to nuclear power, and includes advances in demand response and stationary energy storage. For global vehicle electrification, two major options for decarbonized transportation include battery electric vehicles (BEV) and hydrogen fuel cell electric vehicles (FCEV). With the recent advancements in Li-ion battery (LIB) technologies, BEVs are projected to provide a substantial demand for electricity, enabled by upcoming key technologies for higher-energy and longer-life LIBs. In addition, supercapacitors can help acceleration-boosting and stabilizing electrical system output in BEVs, as well as energy capture from regenerative braking. Furthermore, the global electric car stock will expand to almost 350 million vehicles by 2030, which require battery manufacturers and mineral suppliers to reduce the risks of supply bottlenecks and prevent higher prices.

In my presentation, I will describe the current state of the art and upcoming innovative approaches for the next decade on the design and synthesis of nanostructured energy-storage materials towards enhanced reversible capacity; superior rate performance and cycling stability; superior gravimetric capacitance; and enhanced energy and power densities. Integration of nanostructured pseudocapacitive metal oxides to nano-architectured carbon templates and MXene class materials can provide superior electrochemical performance in supercapacitor applications. Single and multilayer stacked carbonaceous nano-architectures and MXene’s can be employed in LIBs and could also be useful for future applications in hydrogen storage for FCEVs. Next, I will describe most recent efforts for upcycling of polyethylene terephthalate waste and glass waste into active energy storage materials would constitute scalable approaches for deep decarbonization and the means for achieving a circular economy. Waste glass utilization could offer an environmentally-benign and energy-saving route to prepare silicon enriched anodes to boost BEV battery capacity. Finally, I will describe near future approaches for utilizing sulfur-based cathodes, which could offer further boost of battery capacity and enhance BEV performance.

Presentation title: Exergy Management Matrix:  Proposal and an Acrostic Approach


The International Organization for Standardization (ISO) released  ISO 50001: Energy Management Standard in June 2011, which is suitable for any organization – whatever its size, sector or geographical location.  This standard was revised in 2018 by following the same High Level Structure as other widely applied ISO standards, such as ISO 9001 and ISO 14001. So, its integration with other management systems will be easier. Exergy analysis has been considered a powerful tool in assessing the performance of any energy system or process in recent years while any exergy management system standard has not yet been issued. Different energy or environmental management matrices have been developed and proposed  in the literature to give a quick assessment of strengths and weaknesses across selected areas of energy management. This talk proposes an Exergy Management Matrix (ExMM) and deals with various possible meanings of the acrostic “ExMM” from a different perspective.

Energy and Exergy Efficiencies of Geothermal Power Plants

The way to get more from the same resource is to increase efficiency. For this, the current state of efficiency needs to be known. There are many different definitions of efficiency. In general terms, efficiency or performance is defined as the ratio of the ‘desired output’ to ‘required input’. In this presentation, all indices related to energy and exergy efficiency in geothermal power plants are examined and different efficiencies used are systematically defined. This makes it possible to determine the performance of a geothermal power plant from different perspectives. Also, the relationships between different energy and exergy efficiencies are clarified. These efficiency definitions provide a consistent basis for performance improvement studies in geothermal power plants. The efficiency definitions given can be extended to different energy fields.
