PROJECT GOAL

As most data relevant to energy storage exists in a fragmented form, the major work in ESTMAP consists of compiling existing data and exploiting it for an optimized energy systems planning. One of the project goals is to contribute to strengthen the basis for long term strategic planning, optimizing our future energy system and defining potential bottlenecks at an early stage. System modelers, engineers and geologists joined forces for the definition of the format and the content of a database of both above-surface and subsurface storage sites (existing, planned and potential), to ensure that the new set of data will fit the needs for more robust modelling, planning, designing, etc. on a coherent basis and comparable between Member States and other European neighbouring countries as appropriate.

 

SCOPE OF WORK

The project will provide the following output:

1. A geographical energy storage database
The geographical database is one of the main deliverables of the project and will contain the collected and compiled information on developed and future potential subsurface and above-ground storage reservoirs and well as existing storage facilities linked to these reservoirs. Both reservoirs and facilities are described and parameterized by their geological characteristics, technical properties, current development, evaluation of feasibility for the various storage options (e.g. natural gas, compressed air, heat, pumped hydro, etc.) and overlaps with alternative potential for CO2 storage. The database is used to project potential future storage facilities for demonstrating the modelling of the energy systems. The database will be represented in the form of GIS maps and will be linked to the results of the energy systems modelling and analyses.

2. An example system analysis, showing the possibilities of the database
The main objective of the system analysis is to link the data assembled in the database on storage sites and their capacities to the broader energy system. This includes connecting information on transmission (grid), demand (major energy users) and supply (power plants and other production sources including RE). The underlying objective of the system analysis is to strengthen the basis for long term strategic planning and optimizing our future energy system and to define potential bottlenecks at an early stage.
