Target Partner Sought
Contact group 1: Engineering companies (Geology)Smaller companies with excellent knowledge in regional geology of project sites are sought, unable to offer services of optimizing /maximizing reservoirs and SSE.
Contact group 2: Energy groups (electric load & heat provider)Energy groups looking for research collaborations in order to maximize geological reservoirs are sought (concerns operating and accessing new reservoirs).Furthermore EEA offers companionship for project developing energy groups in the field of Societal Systems Engineering, SSE to achieve public acceptance for their own projects.Also in combination of geothermal and oil/gas industry. ‘aquifer gas’
Contact group 3: General Contractors / Venture Capital GroupsEEA offers Site evaluation services (see above).If EEA itself is unable to provide a needed field of competence, EEA can find a network long-time experienced partner providing excellent references.
