Facing predicted uprising shortage of fossil energy reserves and energy crisis going along with it, efforts are taken to develop and implement renewable energy supply. Federal support and private contribution in research and development have yielded good results in the past. However comparing absolute numbers of the enormous fossil energy demand and (until now) relatively little contribution of renewables, it seems hard to believe, that we will be able to substitute them on mid or long term sight. The focus of this work is on the possibilities of a classic oil and gas company to contribute to the renewable market. This was exemplary investigated at the example RAG, which has its technical main quarter in Gampern, Upper Austria –therefore geologically seen in the Molasse Basin. Investigated were: Classic geothermal wells (large scale), combined geothermal heat and power production, heat and electric energy storage, various combinations with other energy sources - by utilizing an evaluation spread sheet Due to economical and technical considerations the heat storage market was identified to have the highest potential, on the short and medium term. To back up this statement, a technical, geological and economical pre investigation of the pilot project “Waste energy optimization utilising a heat storage at Biogas facility Schwarzmayr” in St. Georgen bei Obernberg am Inn was performed. On the long term sight also the compressed air storage concept and CO2 storage might play a role. All this project types would require cost efficient drilling in relative shallow depth
