Title: Innovative Energy Storage Systems for Sustainable Communities

There have been critical technical, economic, environmental and sustainability challenges which are essentially linked to the dimensions of energy. The ways we generate, convert, transfer and use energy directly affect the environment and sustainability. Energy storage has, in this regard, appeared to be the one of the most effective solutions and is expected to play a significant role in providing better environment and sustainability. This particular presentation will focus on two critical subjects: one on energy storage options for renewable energy systems and the other one on energy storage technologies for various community-based applications, ranging from transportation to power generation sectors. Prof. Dincer’s group has been a leader in the area of energy storage technologies for various applications, ranging from renewable energies to batteries. The results of various life cycle assessment studies will be presented to compare the impact categories and their abatement options comparatively. Finally, the challenges, opportunities and future directions in energy storage will be discussed with examples and case studies.

Title: Prospects in Battery Energy Storage Over the Next Decade

The global electrochemical energy storage market ranging from electric vehicles to physical grid storage demands the development of key enabling technologies for high-energy long-life rechargeable batteries and supercapacitors. I will describe the current state of the art and upcoming innovative approaches for the next decade on the design and synthesis of nanostructured 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 can provide superior electrochemical performance in supercapacitor applications. Single and multilayer stacked carbonaceous nano-architectures can be employed in lithium ion batteries and could also be useful for future applications in hydrogen storage. 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 utilizing magnesiothermic-reduction without pre-leaching could offer an environmentally-benign and energy-saving route to prepare silica-source materials employed in fabricating Li-ion battery anodes, a current popular approach to boost EV battery capacity. Near future novel approaches could include the utilization of metal oxide thin film barrier layers to mitigate the polysulfide shuttling effects in Li-S batteries, and enhance their performance and cyclic stability. Finally, I will describe theoretical approaches using density functional theory calculations and molecular dynamics simulations which could provide a fundamental understanding of ionic transport mechanisms and interfacial reactions towards improved design and enhanced performance in batteries and supercapacitors.

Title: Latent heat storage for thermal comfort in buildings

Buildings in their entire life-cycle directly or indirectly are responsible for about 37% of global energy related CO2 emissions. Increase in demand for thermal comfort especially for space cooling further aggravates buildings’ energy consumption. Less than 6% of the energy use in buildings are met by renewables in 2020. Using renewables efficiently and improvements in the building envelopes are urgent to achieve net-zero targets for buildings. Latent heat storage (LHS) systems using Phase Change Materials (PCM) are preferred in many solar energy building applications with their high storage density and smaller temperature swing. Different forms of the PCMs can be used in active and passive storages for buildings. In active storage a PCM heat exchanger is used to store solar thermal energy and to be used later when solar energy is not available. In passive storage, PCM is encapsulated in concrete, wallboard, shutter, ceiling, and floor. In this case solar energy naturally collected by the building elements are used. In this talk, active and passive PCM latent heat storage methods for dwellings including technical aspects of integration and market status will be discussed. Examples from applications in different climates will be given to show benefits and challenges of these systems.

Title: Thermal Energy Storage Application

Thermal Energy Storage (TES) is the temporary storage of high or low temperature energy for later use. It bridges the time gap between energy requirement and energy use. For HVAC and refrigeration application purposes, water and the water ice constitute the principal storage media. Phase Change Materials (PCM) between +4 C and +90C range offer a new horizons and practical application options. By storing daytime warm energy for evening periods and night-time cool energy for day-time cooling requirements, a PCM system can simply bridge the gap between energy availability and energy use and therefore has the potential to achieve considerable environmental as well as economic benefits for many heating and cooling applications. In this talk, it is aimed to cover the commercially available PCM solutions and associated products together with their practical application examples around the World. Practical application guide together with the real application examples around the World will be presented in a format that will aid practicing engineers or consultants to develop an effective and low energy design based on PCM based thermal energy storage cooling / heating and heat recovery systems.

Title: Decarbonisation of the Buildings Sector – Which Way?

Natural gas is the primary fuel in over 75% of the buildings sector heating demand, and so decarbonisation is vital if emissions are to be reduced in line with global, national, local targets. In order to decarbonise the supply side of the buildings sector, low and zero carbon heating systems need to be developed to replace fossil-fuelled systems. There are many potential candidates, such as geothermal and solar-thermal, industrial, and commercial waste heat and heat pumps. However, the variable nature of the low-zero carbon sources, both short term (daily) and long term (seasonal), and mismatches between needs and availability of energy, make decarbonisation difficult to achieve at the individual building and neigbourhood level. District heating (DH) systems in urban settings are ideally placed to provide the infrastructure to match the demand from individual buildings via transient low and zero carbon sources, but require suitable energy storage facilities that can operate over a range of source temperatures. However, integration of low-zero carbon thermal sources is challenging technically due to variability and intermittency of energy sources, and is subject to barriers, such as local acceptance, socioeconomic conditions and local/national policy drivers and constraints. To this end, a case study based on the development of high density, variable-temperature thermochemical energy storage system for low carbon DH, that will decarbonise the heating systems in UK buildings sector in an engaged and sustained manner will be presented.

Title: A novel method for the production of doped-graphene based electrodes used in electrochemical energy storage systems: Yucel's method

Electrochemical energy storage systems (EESSs) are needed for the sustainable use of renewable energy sources such as solar and wind. EESSs such as batteries, supercapacitors and fuel cells offer environmentally friendly and sustainable solutions to meet rapidly increasing global energy demands and address environmental concerns. Due to the superior physical, electrical and mechanical properties of graphene-based materials, they are used in many fields such as energy storage systems, sensors, and optoelectronics. Graphene is generally produced using chemical vapor deposition, epitaxial growth on silicon carbide, chemical (oxidation-reduction) reactions, and electrochemical exfoliation methods. If doping is desired to change the properties of graphene, a new method should be used for doping. We have investigated a novel method (Yucel’s method) to produce doped-graphene on the surface of a graphite working electrode in one step in electrolyte solution by cyclic voltammetry without any secondary step. In this method, graphite is oxidized to graphene oxide at the anode and is simultaneously reduced to graphene in one step. In addition, the doped graphene layers formed on the electrode surface were collected as powder in the electrolyte solution by simultaneous exfoliation. The developed electrode materials were characterized by using electrochemical, spectroscopic and morphological methods. Finally, the use of the obtained doped-graphene electrodes were investigated in electrochemical energy storage systems.
