Abstract: In this talk, hybrid energy with hydrogen deployments strategies are analyzed, modeled usign collaborative simulation. The different modeling levels of hybrid energy systems and hydrogen technologies will be presented as interconnected with community infrastructures. Collaborative simulation approaches are used to evaluate the utilization to plan hydrogen deployment in municipalities and community applications. The concept of energy semantic network is utilized to model energy networks and interconnected infrasturctures while defining key performance indicators. The collaborative simulation will enable the definition of different strategies and scenarios and optimize based on performance, risks, and transactive energy. Case studies will be presnted with energy, nuclear, transportation, hydrogen, and water networks as interfaced with infrastructures.

Abstract: The author’s of this Keynote study on compensation, meaning reduction of excessive currents in electrical systems, are motivated by the need to lower the cost of electric energy delivery. This motivation strongly fits the power systems strategy of lowering, by power dispatch, the costs of energy delivery, as well as reducing the impact of electric energy production upon the environment. The development of renewable energy sources seems to be in sharp contrast to this optimization-oriented motivation. Optimization requires that the cost of harvesting such sources is known. It is a compound of various factors, such as the environmental impact, the use of the Earth’s resources, development, maintenance, and profits, to finally include social and political implications. Unfortunately, the latest seems to be the dominating ones. Renewable sources are supported by various economic incentives from states’ budgets. This support disturbs free market mechanisms, so economic optimization is losing its sense. Wind and solar energy do not cost, so in public perception, their use as electricity sources should reduce energy bills. However, the former president of the European Union (EU) Council said recently that bills for electricity in the EU are 2.5 times higher than in the US. He blamed EU policy towards reducing CO2 emissions for that. Government subsidies are not visible, moreover, in bills for electricity. Their increase could be only the tip of a huge iceberg. Consequently, the question: “Who knows how much harvesting renewable sources costs?” is legitimate and deserves investigation.

Abstract: This study presents the development of an experimental heat pump prototype based on the elastocaloric effect—a promising solid-state cooling mechanism that leverages the reversible thermal response of Shape Memory Alloys (SMAs) under mechanical loading and unloading. Unlike conventional vapor-compression systems, elastocaloric cooling offers a potentially more energy-efficient and environmentally friendly alternative, as it eliminates the need for refrigerants with high Global Warming Potential. The research is part of the project SUSSTAINEBLE (a Solution Using Solid-STate cooling: An INvestment Eco-compatiBLE) funded by the Ministry of University and Research (MUR) of Italy. The aim of this research, carried out by the group of the University of Naples Federico II, is the developing of a demonstrative prototype of the first Italian elastocaloric device for air conditioning. Air is the auxiliary fluid that will be used to avoid an intermediate heat exchanger. The operation of the device based on the AeR cycle uses a rotary mechanism that ensures a continuous flow of hot and cold air. A 2D rotative numerical model has been developed through COMSOL to attain the device's potential cooling and heating capacities and to optimize the geometrical parameters and the operative conditions of the device. The experimental setup utilizes nickel-titanium (NiTi) alloy elements, selected for their significant latent heat and mechanical resilience. The results of numerical simulations carried out following the optimization of the geometric parameters of the device are presented to analyze its potential in terms of energy performance. This work contributes to the growing body of research on solid-state cooling technologies and provides insights into the engineering and operational considerations necessary for scaling elastocaloric systems toward commercial viability.

Abstract: Nickel-titanium alloys commonly called as nitinol, a Shape Memory Alloy (SMA), is recognized as next generation alloy [1]. Nitinol is a family of titanium based intermetallic materials that contain nearly equal amount of nickel and titanium, has been widely employed in many applications such as biomedical, actuators, aerospace and automotive devices. In near-equiatomic NiTi alloys, shape memory effect and superelasticity are due to thermoelastic martensitic transformation from parent austenite phase with B2 structure to the monoclinic (M) or rhombohedral (R) martensitic phase transformation. The biocompatibility, and exquisite properties of nitinol SMA have gained a lot of popularity among these several combinations, and allow to obtain smart material with shape memory effect and superelastic properties. Due to the functional properties of nitinol SMAs, their biomedical application has proven to be more successful by increasing the possibility as well as the performance of minimally invasive surgeries. The combination of nickel-titanium SMA is highly biocompatible which makes them useful as orthopedic implants, surgical instruments, cardiovascular devices, and orthodontic devices. The reversible austenite-to-martensite solid state transition under stress that occurs in Nitinol is associated to a release of heat, and this phenomenon is widely investigated in literature for the application in solid-state cooling devices [2]. Elastocaloric cooling based on NiTi SMA exhibits excellent cooling capabilities. Due to the high specific latent heats activated by mechanical loading/unloading, large temperature changes can be generated in the material. The small required work input enables a high coefficient of performance. Solid-state cooling is an environmentally friendly, no global warming potential alternative to vapor compression-based systems.
