1. Optimization of ground-coupled systems for heating and cooling of buildings
Abstract : The use of ground-coupled systems in commercial buildings offers economic as well as environmental advantages. When both heating and cooling is required, a ground-coupled system can function both as a heat source and a heat sink. At the same time, it can also serve as a short term as well as a seasonal storage. READ MORE

2. Developments in Ground Heat Storage Modeling
Abstract : Ground heat storage systems can play an important role for the reduction of green house gases emissions by increasing the exploitation of renewable energy sources and “waste heat” with a consequent diminution of the use of fossil fuels.A ground heat storage consists in an array of vertical boreholes placed in such a way that promotes the mutual thermal interaction between the ground heat exchangers creating the necessary conditions required to effectively store and retrieve heat.

4. Computational Studies of Hydrogen Storage Materials : Physisorbed and Chemisorbed Systems
Abstract : This thesis deals with first-principles calculations based on density functional theory to investigate hydrogen storage related properties in various high-surface area materials and the ground state crystal structures in alkaline earth dicarbide systems. High-surface area materials have been shown to be very promising for hydrogen storage applications owing to them containing numerous hydrogen adsorption sites and good kinetics for adsorption/desorption.

5. Water Curtains in Gas Storage. An Experimental Study
Abstract : Water curtains have been used for more than 20 years to prevent the escape of gas from caverns excavated in rock. Today, the use of water curtains appears to be increasing, with applications in various forms of storage caverns. READ MORE
