PART 1Executive Overview
1Definition

A thermal energy storage system that uses sand to store and release heat, primarily intended for seasonal district heating.

Category

Seasonal district heat
Stage
PILOT
2Problem It Solves

Integrating intermittent renewable sources into a stable and reliable grid by providing long-term storage of heat from excess energy production.

3Lifecycle / Journey Stage

PART 2Technical & Manufacturing
4How It Works

Surplus renewable electricity heats sand in insulated silos. The heated sand stores the thermal energy, which can be released later as needed for district heating purposes.

5Materials Used
6Manufacturing / Creation Process

The process involves sourcing sand, insulating silos, installing heaters, and setting up monitoring systems to ensure efficient operation.

7Build Process

Initial setup includes site preparation for the silos, installation of heating elements, insulation, and integration with renewable power generation sources. Ongoing processes involve regular maintenance and optimization of thermal transfer efficiency.
