6 FAQs about [Pit storage Micronesia]

What is a pit thermal energy storage (PTEs)?

Selection of real world case studies of different types of STES. Pit Thermal Energy Storage (PTES) consists of a ground excavated site filled with a storage medium, covered by a floating lid and optionally insulated on the sides .

What is a pit storage medium?

The storage medium is usually water (although this is not the only option [117,118]). Pit storage (P-TES) are pits buried in the ground and coated with a plastic layer. The storage medium is a mixture of gravel and water. The storage is charged by direct hot water injection or by use of pipes where the heat transfer fluid flows.

Where is pit heat storage located?

The pit heat storage is located between the Holbæk highway and a main water pipe (bonnaledning) supplying Copenhagen as shown in Figure 1. Figure 1: Site plan. As can be seen in Figure 1, the storage facility is squeezed between a main water pipe and the Holbæk highway.

Is it cost-effective to insulate pit storage?

Previous calculations show that it is not cost-effective to insulate the sides and/or bottom of the pit storage. The primary purpose of the lid is to limit heat loss from the storage, but the lid must also ensure that the water quality in the storage is not reduced.

How to set up a pit heat storage facility?

The cheapest way to establish a pit heat storage is with soil balance. This means that the excavated soil is compacted and used as an embankment around the storage facility. In addition, the slope should preferably not be steeper than 1:1.5 for the mem-brane work, and the heat storage must be 70.000 m3.

When did pit heat storage start?

Construction of the pit heat storage began in spring 2020. Excavation, construction of the inlet and outlet arrangement, installation of the leakage detection system, PP liner and a thin PE liner to protect against dirt, and UV light during water filling proceeded as planned.
