In an era where energy efficiency and sustainability are paramount, a groundbreaking study from the Technical University of Košice is shedding light on innovative approaches to thermal energy storage (TES) that could reshape the construction sector. This research, led by Michal Gorás from the Institute of Architectural Engineering, delves into tank thermal energy storage (TTES) systems, particularly focusing on their application in European buildings, which account for nearly 40% of energy consumption in the European Union.
The study highlights a critical challenge in renewable energy—namely, the intermittent nature of solar energy. While solar power has emerged as a leading renewable resource, its availability fluctuates seasonally, creating a mismatch between energy supply and demand. This is especially pronounced during winter months when energy demand peaks but solar availability declines. Gorás notes, “By implementing effective thermal energy storage solutions, we can bridge the gap between energy generation and consumption, ultimately leading to a more sustainable energy landscape.”
Gorás and his team conducted experiments using three different underground tanks of varying sizes, discovering that the size of the tank significantly influences cooling efficiency and energy retention. Their findings reveal that covering the water surface in these tanks can effectively double the energy retention time, thereby extending the cooling period. “A larger tank cools more slowly, allowing for the formation of temperature layers that enhance energy utilization,” Gorás explains. This stratification not only reduces heat losses but also contributes to lower CO₂ emissions, aligning with the EU’s ambitious climate goals.
The implications of this research are profound for the construction industry. As building codes increasingly mandate energy efficiency and sustainability, the adoption of TTES systems can provide a competitive edge. Developers and architects can leverage these systems to ensure that buildings not only meet regulatory requirements but also reduce operational costs through improved energy management. The study emphasizes that effective implementation of TES could lead to significant reductions in energy demand and greenhouse gas emissions, making a compelling case for the integration of these technologies in new construction projects.
Moreover, the research presents an opportunity for innovation in building design. By incorporating TTES systems, construction professionals can create more resilient buildings that adapt to fluctuating energy availability. This adaptability is crucial as the industry shifts toward renewable energy sources, ensuring that buildings remain functional and efficient regardless of external conditions.
The study, published in the journal ‘Energies,’ underscores the importance of advancing thermal energy storage technologies in the quest for sustainable energy solutions. As Gorás concludes, “Our research not only enhances the understanding of thermal energy storage but also paves the way for practical applications that can transform the construction sector.”
