1. An arrangement for storing thermal energy, comprising:
- at least two tunnels (1a, 1b) holding a liquid; and
a heat exchanger;
wherein one or more of said at least two tunnels are connected to said heat exchanger such that fluid communication is allowed from said at least two tunnels to said heat exchanger;
wherein said at least two tunnels (1a, 1b) are connected to each other by a plurality of channels (2), such that fluid communication is allowed between said at least two tunnels (1a, 1b), said plurality of channels (2) being arranged in a pattern in between said at least two tunnels (1a, 1b),wherein said at least two tunnels (1a, 1b) comprise an inner tunnel (1a) and an outer tunnel (1b),wherein each of the inner tunnel (1a) and the outer tunnel (1b) is configured as a helix, the inner tunnel (1a) forming an inner helix and the outer tunnel (1b) forming an outer helix, andwherein the outer helix is arranged around the inner helix.

Abstract
An arrangement for storing thermal energy has at least two tunnels (1a, 1b) for holding a fluid. The tunnels (1a, 1b) are connected to each other by at least one channel (2), such that fluid communication is allowed between the tunnels (1a, 1b). Each of the inner tunnel (1a) and the outer tunnel (1b) is configured as a helix, the inner tunnel (1a) forming an inner helix and the outer tunnel (1b) forming an outer helix.
