In light of the continuous heatwaves, new and creative ways of storing thermal energy, such as ice storage air conditioning, are emerging. These solutions help reduce the high demand for electricity during peak times by storing cold energy in ice. It is an effective and affordable method for managing excess energy in large buildings. Additionally, other systems for storing heat and cold are gaining popularity as the effects of climate change become more severe. These systems play a crucial role in not only reducing the impact of cooling on the environment but also in adapting to the challenges posed by global warming. In a world where heatwaves are breaking records and climate change is a growing threat, it is becoming increasingly important to embrace and advance these innovative thermal storage solutions.
As the Earth encounters scorching hot weather, there is a growing demand for creative methods to preserve coolness and warmth. Nations across the globe are wrestling with extreme climatic occurrences, as a few American cities witness back-to-back days of triple-digit temperature records. In these extremely hot conditions, conventional cooling mechanisms may struggle to cope, resulting in discomfort and possible health hazards.
Cool Solution: Ice Thermal Storage
Ice storage air conditioning is an efficient way to reduce energy usage during times of high electricity demand. It involves using ice to store thermal energy, which can provide significant benefits. For instance, the high heat capacity of water allows just one metric ton of it to store a remarkable 334 megajoules of energy, which is roughly equal to 93 kilowatt-hours. This approach is particularly advantageous in large buildings, as well as in applications like ground freezing for mining and tunneling, and combustion gas turbine air inlet cooling. By harnessing ice as a thermal storage medium, ice storage air conditioning offers several advantages compared to traditional air conditioning systems. Firstly, it allows for the utilization of cheaper electricity rates during off-peak hours, which can result in cost savings. Secondly, it helps to reduce electricity demand during periods of peak usage, which can contribute to a more stable and reliable electrical grid. Overall, ice storage air conditioning presents a sustainable and practical alternative to conventional air conditioning systems. By capitalizing on the thermal storage capabilities of ice, it offers an energy-efficient method to cool large spaces while minimizing the strain on the electrical grid.
Dealing with scorching city temperatures? These advancements come to our rescue
Many European cities are currently experiencing intense heatwaves. How can we ensure that the high temperatures are more manageable?
A prime illustration of the utilization of ice storage air conditioning can be seen in the Alitalia facility situated in Europe. The entire cooling requirements for the air conditioning and computer systems within the complex are catered to by ice-chiller thermal storage coils, boasting a combined storage capacity of 65,000 kWh. This installation is among the most extensive ice storage setups globally.
Nostromo Energy, a company that specializes in innovative energy solutions, has introduced a cutting-edge ice-powered thermal energy storage system in two renowned hotels in the United States: the Beverly Hilton and Waldorf Astoria Beverly Hills. The system, managed by advanced cloud-based software, ensures efficient and optimized operation at all times. As a result, both hotels can significantly cut down on their cooling expenses, enjoying savings ranging from 30% to 50%. Moreover, this eco-friendly solution enables the hotels to reduce carbon emissions by approximately 200 metric tons annually. Additionally, during power outages, the stored cold energy can be utilized as a backup power source to maintain the cooling systems' functionality.
The Future Of Cool
The growing fascination with Cold Thermal Energy Storage (CTES) technology is not limited to ice alone. Instead of relying on electricity to produce ice, CTES directly stores cold temperature. It works by storing thermal energy when there is less need for refrigeration, and this stored energy is then utilized during peak hours to lower the electricity consumption of the refrigeration system. By incorporating phase change materials (PCMs), which can store and release thermal energy at a consistent temperature, CTES technology further enhances energy efficiency.
Europe is struggling with scorching heat. What measures can cities take to defend themselves against this adversary?
Heat has become one of the biggest adversaries for Europe. In the fresh series called "Europe combating heat," IO investigates the methods cities can employ to defend against it.
The ongoing battle against climate change highlights the significance of creative methods to store thermal energy and minimize our carbon emissions. These advancements play a vital role in mitigating the negative effects of cooling on the environment, while also helping us adapt to the escalating challenges of global warming. With heatwaves becoming increasingly frequent, the demand for effective and sustainable cooling options is growing rapidly. Therefore, it is crucial that we prioritize the creation and acceptance of these innovative thermal energy storage solutions.
