Redox-Flow batteries can play a crucial role in the future electricity supply in order to balance the time lag between the generation of electrical energy from photovoltaics or wind power and the demand for electrical energy. However, to deploy the technology on a large scale, significant cost reductions are required. A thorough knowledge of the reactions and processes taking place within a redox-flow battery is very helpful for this task and this knowledge can be significantly improved by using a suitable mathematical model to describe the processes in a single cell of a redox-flow battery. Nevertheless, this requires a valid model that has been compared with experimental data and that can reproduce these data plausibly and validly. In this thesis, the validation of a two-dimensional model for the description of potential and current density distributions in the porous electrodes of a vanadium redox-flow battery is presented, taking into account effects of kinetics and mass transport. Newly developed potential probes are used for in-situ measurement of solid and liquid phase potentials within a single cell of a vanadium redox-flow battery. The description of the measured cell voltage and potential probe signals by the model reveals a good congruence between the model and the experimental data, so the model can be regarded as valid. Additional suggestions for improvements of the model and the implementation of further models describing membrane crossover effects or electrolyte properties are given.

In this work, a holistic approach is used to develop a multi-physical model of the Vanadium Redox Flow Battery on a system level. The model is validated with experimental data from three flow battery manufacturers and is then deployed in an extensive parameter study for designing a flow battery cell. Using finite element analysis (FEA), twenty-four different cell designs are derived, which vary in electrode area and the design of the electrolyte inlet and outlet supply channels. The performance of the designs is then simulated in a single-stack and a three-stack string system. The presented model is also deployed in a flow rate optimization study. Here, a novel strategy involving the model-based optimization of operation-points defined by state-of-charge and charging or discharging current is presented and compared to conventional flow rate control strategies. Finally, a stack voltage controller is introduced, which prevents the violation of cell voltage limits as long as the pump capacity is not fully utilized.

This book outlines issues related to massive integration of electric and plug-in hybrid electric vehicles into power grids. Electricity is becoming the preferred energy vector for the next new generation of road vehicles. It is widely acknowledged that road vehicles based on full electric or hybrid drives can mitigate problems related to fossil fuel dependence. This book explains the emerging and understanding of storage systems for electric and plug-in hybrid vehicles. The recharging stations for these types of vehicles might represent a great advantage for the electric grid by facilitating integration of renewable and distributed energy production. This book presents a broad review from analyzing current literature to on-going research projects about the new power technologies related to the various charging architectures for electric and plug-in hybrid vehicles. Specifically focusing on DC fast charging operations, as well as, grid-connected power converters and the full range of energy storage systems. These key components are analyzed for distributed generation and charging system integration into micro-grids. The authors demonstrate that these storage systems represent effective interfaces for the control and management of renewable and sustainable distributed energy resources. New standards and applications are emerging from micro-grid pilot projects around the world and case studies demonstrate the convenience and feasibility of distributed energy management. The material in this unique volume discusses potential avenues for further research toward achieving more reliable, more secure and cleaner energy.

The 3rd Annual Conference of the Portuguese Association of Energy Economics – APEEN and the International Meeting on Energy and Environmental Economics – ME3 took place on the 18-19 October 2018 in Braga, Portugal. The event was hosted by the Universidade do Minho and gathered the contributions of specialists in Energy and Environmental Economics to enrich the debate about the many issues raised by the management of resources and waste. The main topic was Managing Resources and Waste: challenges for Energy and Environmental Economics beyond 2030. Natural resources are the keystone in environmental and energy economics. Nowadays, resource management cannot ignore waste, traditionally seen as a by-product of consumption and production decisions, but increasingly recognized as a source of energy or as new type of resource. The APEEN & ME3 joint conference had over 50 presentations from researchers from all over the world and lively discussions. Some of these presentations are summarized in the short papers compiled in this Book of Proceedings. We are grateful to have had the presence and contribution of the keynote speakers: Maria L. Loureiro (Universidade de Santiago de Compostela) and Martin Brocklehurst (Kempley Green Consultants). Their speeches challenged us now to think of new research and business opportunities beyond 2030. On behalf of the organizing committee, I thank our sponsor, LIPOR, and all presenters for their academic excellence and lively participation. Lígia Pinto, Universidade do Minho
