What is a mine storage & how does it work?

This is where solutions such as demand flexibility and short-term energy storage comes in. A mine storage can be used both for grid-scale and short-term storage, thereby addressing both the production/consumption mismatch and the stability of the grid. In other words: mine storages can be the key that enables the transition to green energy.

What makes mine storage a suitable solution?

Our solution is always designed based on how revenue will be generated. Mine Storage is a suitable solution for both bulk storage and ancillary services. For each mine storage plant, the operational model is developed to optimise the revenue based upon the conditions of the local market.

Can abandoned mines be used to store energy?

Using water and gravity to store energy is one of the most mature and widespread technologies for energy storage available today. In fact, more than 90 % of the current grid-supporting energy storage is based on water and gravity. Using abandoned mines has several benefits on different levels.

How long does mine storage take?

A mine storage can vary in size from 15 to 200 MW and in discharge time from 2 to 12 hours, depending on the need in the area where it is located. To put this in context, A 100 MW facility can provide a city of 250,000 households with energy for up to 12 hours.

Can an abandoned mine be turned into a mine storage?

Turning an abandoned mine into a mine storage turns it from a liability into a circular asset. Given the compelling business case, the high round trip efficiency and the long lifespan of a mine storage, the levelized cost of energy storage (LCOS) is very competitive.

How do you know if a mine has a storage system?

The best indicator of the existence of a mine storage is that the water level in the upper water reservoir varies slightly. Mine Storage uses the same proven technology as traditional pumped storage, but applies it in an innovative way by using the height difference that you can find in decommissioned mines.
