European Workshop on Underground Energy Storage

06.26.2019
BRGM co-organises the European Workshop on Underground Energy Storage which will take place in Paris on 7-8 November 2019.

Overview

Energy storage will play a pivotal role in future energy systems compatible with a carbon-neutral and environmentally friendly society. It will enable to optimize the integration of renewable and recoverable energies into the electricity and heat mix and to contribute to the flexibility of energy systems, alongside improved grid interconnectivity, smart grids and demand-response functionalities. It will also facilitate sector coupling by the use of renewable power for producing green fuel in the mobility sector and green raw material for the chemical industry like hydrogen.

Energy storage in the subsurface has the potential to become an important component of transition to low carbon energy . Storing energy in the underground can lead to larger-scale, longer-term and safer solutions than above ground energy storage technologies, thus complementing the range of storage technologies to be able to meet very diverse needs.

Organisers

This European workshop on Underground energy storage is organised by ENeRG, the European Network for Research in Geo-Energy, in collaboration with:

  • EuroGeoSurveys’ GeoEnergy Expert Group
  • the ANR FLUIDSTORY project
  • BRGM, the French Geological Survey

The workshop is organised in Paris as a back-to-back event with the national energy storage days organised each year by the Energy Storage Club of ATEE, the French Technical Association on Energy and Environment:

  • 5-6 November: ATEE Days on Energy Storage (language: French) - Contact: Patrick Canal (p.canal@atee.fr)
  • 7-8 November: European workshop on Underground Energy Storage (language: English) - Contact: Isabelle Czernichowski-Lauriol (i.czernichowski@brgm.fr)

Attendance to both events is encouraged.

Objectives of the european workshop

Subsurface energy storage represents a complex and broadly evolving field of research, as it covers multiple scales of application, a variety of end-user profiles, and different types of energy carriers. Subsurface storage capacities are present in many types of geological formations, each of which has its own criteria for identifying techno-economic viability. Some of the subsurface energy storage technologies (e.g. natural gas storage) have been applied at large scale for decades, while others have thus far been applied in pilot projects or at modest scale only (e.g. compressed air energy storage, heat storage). It is crucial to further increase our level of understanding of subsurface energy storage potential based on new geoscientific data, improved models and common agreed assessment principles.

The key to unravelling the full potential and effective implementation of large-scale subsurface energy storage lies in the integration of geological knowledge, engineering solutions, market economy information and a comprehensive analysis of the entire energy system. Close cooperation between all actors from science, industry and policy areas is therefore essential to a successful development.

The objectives of the workshop are to discuss current technological status and research needs for the development of the subsurface energy storage technologies, and exchange with energy producers and consumers who need energy storage solutions.
