Can low-temperature resources be used for power generation?Increasingly, low-temperature resources below 150°C—once reserved for direct-use applications such as heating, greenhouses, fisheries, and mineral recovery—can now be used for power generation under the right conditions.
How do thermal energy storage systems work?Thermal energy storage (TES) systems can help store energy on the timescales of these fluctuations. TES units are integrated into pumped thermal energy storage (PTES) systems, which operate through three subprocesses: charging, storage and discharging.
Can 'long-term sustainable' fluids be used in power and air conditioning cycles?This could be achieved with innovative power, air conditioning and refrigeration cycles utilising ‘long-term sustainable’ (LTS) fluids, especially air, water and CO 2. In the article we provide a rational approach to the future use of working fluids based on our interpretation of the available technical evidence.
Can low-grade heat reduce energy consumption-fossil fuel dependency?CHP is a proven technology with technical, economic and environmental benefits using the low-grade heat for both electrical and thermal power supply. Authors agree that the key to reduce future energy consumption-fossil fuel dependency lies on maximum utility from low-grade heat.
Are volatile fluids the future of cooling & power generation?From our point of view, volatile fluids will continue to play major roles in cooling and power generation in the future. However, presented new technologies using air/water couple will be the key to optimise energy efficiency–safety also optimal usage of volatile fluids with minimal environmental impact.
Can a two-zone water storage tank be used as thermal energy storage?A two-zone water storage tank with a storage temperature of 115°C is used as thermal energy storage. For discharge, an Organic Rankine Cycle (ORC) and, alternatively, a transcritical CO 2 heat engine are investigated. The considered concepts are modelled and simulated as stationary processes using the EBSILON Professional softwa
