SEMINAR: Recent advancements in Thermal Energy Storage using Phase Change Materials
Energy storage must play a crucial role in the widespread adoption of renewable energy sources because they are intermittent. In addition, energy storage is also important in matching the electrical power load with the generation capacity to improve the overall power plant efficiency. This point has been recognized in the recent California state mandate for the electrical utility companies to have energy storage at each power plant in order to utilize their generation capacity more efficiently.
While electrochemical energy storage is still very expensive, thermal energy storage can be cost effective even at the present commercial development level, especially for solar CSP plants and conventional thermal power plants. Use of phase change materials for thermal energy storage can increase the storage density, reduce the size and therefore reduce the costs even further. However, it presents certain challenges in terms of poor heat transfer and material compatibility issues.
This presentation will describe how these challenges have been overcome by innovative and transformative solutions to develop thermal energy storage using phase change materials at a system cost of less than $15/kWhth as compared to the present commercial thermal energy costs of more than $30/kWhth.
