Solar Thermal Energy Storage System Pdf

For on demand electricity production when the sun is not shining.

Solar thermal energy storage system pdf. The solar energy system was designed to supply 661 gj annually or 2 62 gj m 2 a which was five times higher than the actual value of 132 3 gj this large discrepancy was caused by. The integrated system contains concentrated solar thermal energy using parabolic trough technology with a solar thermal energy storage system. System is a necessity for the solar field to operate continuously and to generate electricity efficiently. The layout of the multigeneration system for case study 4 is shown in fig.

10 25 mpa 2 2 3 heat discharging mode 15 h. Csp and thermal energy storage concentrating solar power uses mirrors to concentrate the sun s energy onto a receiver to provide heat to spin a turbine generator to produce electricity hot fluid can be stored as thermal energy efficiently and inexpensively. Lovegrove solar energy vol. Introduction thermal energy thermal energy storage solar energy and tes tes methods sensible tes latent tes cold thermal energy storage ctes seasona.

I the high solar storage thermal and overflow losses. 187 194 2002 operating pressure. Reversing the flow moves the thermocline upward and removes thermal energy from the system to generate steam and electricity. However there are a growing number of facilities that use seasonal thermal energy storage stes enabling solar energy to be stored in summer for space heating use during winter.

High temperature heat transfer fluid flows into the top of the thermocline and exits the bottom at low temperature. 500 860 c operating pressure. Four times greater than the design value of 37 gj. Most practical active solar heating systems provide storage from a few hours to a day s worth of energy collected.

In this study a 4 4 kw stationary compression ignition engine is coupled with a double pipe heat exchanger vapour absorption refrigeration system and thermal energy storage system to achieve. Summary this chapter contains sections titled. The 90 000 thermal energy storage system is expected to produce about 90 000 kwh per year which represents an annual reduction of 63 metric tons of co 2 emissions and cost savings.
