Form: Energy storage

Electric Thermal Energy Storage Siemens AG

This project shows, how - solely through architectonical decisions - a technical plant is transformed into a work of architecture.

The constellation of exterior forms and their particular consistency induce a certain impression on their users and observers. This impact by the material substance arises solely by the means of architecture.

1 / 3
Electricity from solar power is largely generated when not in demand. Intermediate storage is the new key technology.
2 / 3
Heat contained in vulcanic rocks is an efficient medium to store electricity. The pilot conversion plant is a straight technical construction.
3 / 3
ETES - Electric Thermal Energy Storage – unlike electricity – is a very visible technology requiring urban integration.
3 / 3
We are transforming this technical plant into a work of architecture. In a first step all technical components are conceptually separated.
3 / 3
The energy reservoir will be scaled up in coming projects. A concise volume provides a recognisable form therefor.
3 / 3
A slanted roof, which collects rainwater, covers the energy storage. Technical components are organised in a compact and efficient building form.
3 / 3
A flexible maintenance area in-between storage and plant building completes this very compact facility.
3 / 3
Remaining surface areas are publicly accessible green areas for rainwater infiltration and air filtration.
3 / 3
The conglomerate of technical modules as an urban structure and landmark - a self-confident statement for optimistic departures into the energy revolution.
