Integration of Thermal Energy Storage into Energy Network

Research Paper (undergraduate) from the year 2017 in the subject Engineering - Chemical Engineering grade: 65.00 University of Birmingham (University of Birmingham) course: Chemical Engineering language: English abstract: Fossil fuel plays a major role in the society and they are commonly used for the heat and power production for the commercial and residential applications. According to UKERC Research Report heat accounts for around 47% of the total energy consumption in the UK and 33% of carbon emissions. Approximately 80% of this heat account for space and water heating. At the same time a significant amount of heat is being used by the industry sector 24% for industrial processes. The corporation of thermal energy storage system is very beneficial for CO2 emission reduction and energy saving. And it is the key technology to balancing the energy system stable with the increasing capacity from wind.This research report uses the concept of Wind-Powered Thermal Energy System (WTES) recently proposed by (2015 Okazaki et al) with Latent-Thermal Energy Storage (TES) design to produce stable heat for industrial application and also looked at the economics of h-WTES (Direct heat production) and electrical-WTES (Indirect heat Production using electrical heater) with thermal energy storage for heat generation and compared the results with the traditional gas boiler. This paper demonstrates the potential and probable costs of different WTES with thermal energy storage and a design of tube-in-tank phase change thermal storage system by using a previously developed an effectiveness-NTU method potentially applicable for the industrial sector. From the results it was identified that it is more economically feasible to generate heat from h-WTES (Direct heat production) with thermal storage than e-WTES (indirect heat production). 56.2 £/MWh-t and 63.36 £/MWh-t the levelized cost of heat for h-WTES and e-WTES respectively. Also the result suggested that the r
