Title: Thermochemical energy storage – a versatile game-changer?

Abstract:
In 2017, the International Energy Agency announced the 40-40 goal: Within 2040, 40 % of the global energy demand shall be provided by renewable energy sources. This already ongoing transformation towards renewables focusses heavily on fluctuating energy sources as wind or sun. To cover the resulting mismatch between demand and supply, especially thermal energy storage becomes increasingly important.
Among thermal storage concepts, thermochemical energy storage is still the most experimental technique, although featuring distinct advantages as loss-less (long-term) storage, applicability over a broad range of temperatures and highest storage densities.
Based on recent research different aspects developing thermochemical energy storage materials are presented: A proper selection of the material defines its application for varying technological environments; Complete understanding of the chemical processes during the storage cycle allows to tune and enhance the performance of the thermochemical systems to match demand-sided requirements; Control of the reaction conditions allows for fine-tuning towards applicability.

Title: High share of variable renewables resources: Risks and opportunities

Abstract: The new plans of decarbonization of the energy system in the UE includes ambitious objectives for the renewables' share in the power system in year 2030. In countries with low dispatchable renewable resources, as hydro power or biomass, most of this share must come from Variable Renewable Energies (VRE), such as photovoltaics or wind energy. Large quantities of VRE pose substantial challenges to the technical management of power systems, as well as to the electricity market design and will have effects on energy costs. In this presentation, these points will be addressed and the envisaged consequences outlined. The consequences include effects on electricity costs, high installed capacity, energy spillage and inadequacies of current electricity market design. The increasing share of VRE must be accompanied by proper measures, such as grid and interconnections reinforcements, storage devices and demand response. The well known methodology of screening curves will be used in the presentation to illustrate with examples some of the foreseeable outcomes of this necessary transition.

Title: High flexibility analysis of biodiesel production using multi-feedstock oil

Abstract: Multi-feedstock biodiesel was purposed to overcome the shortage of single oil raw material in biodiesel production. However, the high yield of biodiesel was hardly achieved when the different types of oils was used since they have different characteristics even though the processing condition was the same. This research was aimed to evaluate the use of multi-oils with wide range of fatty acids as raw materials and its process flexibility of biodiesel production. The result shows that the multi-feedstock biodiesel have potential as an alternative energy to reduce the dependency of fossil oil. The results also showed that multi-feedstock plant of biodiesel give high flexibility to the change of raw materials and process but give different result to engine performance and emissions.

Title: Fluid Structure Interaction Modelling of Tidal Current Turbines

Abstract: In this talk, an overview will be presented on the ocean current energy and the devices for extraction of tides energy. Then a specific interest will be given to the fluid structure interaction modeling of tidal current turbines. Tidal current energy has the potential to provide a new renewable energy source to the world. Tidal energy technology has successfully gone through various development phases, with demonstration systems currently operating in relevant environments at pre-commercial and commercial scales. Tidal Current Turbines (TCTs) often derive their design principals from wind turbine design. However, there are certain key differences that needs careful consideration. The proper understanding of device behavior is necessary to make this technology cost effective and reliable.
Although RANS CFD based numerical models can model the hydrodynamic behavior of a TCT but it has the limitation that it assumes the blades to be rigid. Numerical models capable of accounting for the Fluid Structure Interaction (FSI) and hydroelastic behavior of the turbine blade can provide a better approximation of the turbine performance and near flow fields. Some FSI studies have already been conducted to gain an insight into the performance of tidal turbine. However, more such studies are still needed to further the understanding of the design and performance of turbine.
