6 FAQs about [Neckarsulm seasonal solar thermal energy storage system]
Does seasonal thermal energy storage exist in Germany?
The paper presents an overview of the present status of research, development and demonstration of seasonal thermal energy storage in Germany. The brief review is focused on solar assisted district heating systems with large scale seasonal thermal energy storage.
Can seasonal thermal energy storage replace fossil fuels?
1. INTRODUCTION In Middle Europe seasonal thermal energy storage offers a great potential for substituting fossil fuels by utilization of waste heat from cogeneration heat and power plants (CHP) and of solar energy for hot water preparation and space heating.
How much does solar heat cost in Germany?
The solar heat costs that have been reached today by CSHPSS-systems in Germany are, depending on the size of the system, between 16 and 42 EuroCt/kWh. In Germany, this is still more than 3 times higher than heat supply from fossil fuels.
Where is the newest heat storage plant located?
The actually newest plant in operation is situated in Attenkirchen. For seasonal heat storage a hybrid storage concept has been developed, which consists of a 500 m3 underground not thermally insulated concrete water tank in the centre and surrounding vertical borehole heat exchangers (ducts), which open up an additional ground volume of 9,350 m3.
What is a gravel-water heat store in Chemnitz?
In 1996, an underground gravel-water heat store was built in Chemnitz in the course of a necessary soil decontamination. The store is designed for a maximum temperature of 85 °C and is directly charged or discharged. The system is designed for an annual heat demand of 1,200 MWh/a and a solar fraction of 42 %.
How does a solar energy store work?
The system is designed for an annual heat demand of 1,200 MWh/a and a solar fraction of 42 %. Since spring 2000 the store is charged with the solar collectors of the first phase of construction. The long-term heat storage via vertical ducts in the ground has been investigated in a previous project.
