Carbon capture and storage (CCS)

Development and application of CO2 capture and storage technology is increasingly in the centre of attention as one of the potential solutions for reducing emission into the atmosphere.

MOL, as a permanently developing company, has implemented major efforts in internal research and development focusing onto the issue of storage.




As the first step MOL set up a CCS working team for investigating opportunities for storing carbon dioxide in its depleted hydrocarbon reservoirs. Then it established a scientific cooperation with experts of Eötvös Loránd Geophysical Institute (ELGI). MOL also joined an international consortium, ‘ECCO’ (European CO2 value chain project) with the purpose of investigating options for capture and storage in Europe, which has been subsidized for 3 years by the European Commission since September 2008.

Results achieved from 2008:

  • MOL carried out a complex underground and surface technology investigation of domestic oil and gas fields regarding to (IOR, EOR, EGR) Enhanced Oil and Gas Recovery possibilities with the potential for CO2 storage;
  • The CO2 storage potential of the domestic depleted hydrocarbon reservoirs was determined;
  • Geological and technical risks were analyzed and risk management was carried out;
  • MOL-ELGI experts investigated and analyzed the applicability of international experiences in the territory of the Pannonian Basin;
  • Hungarian CO2 storage potential was determined considering the following:
    • Deep saltwater aquifers,
    • EOR and EGR technologies combined with CO2 storage,
    • Storage options in un-mineable coal beds;
  • CO2 storage opportunities in Hungary were analyzed - including volumetric estimates for the identified geological formations.
  • Case studies were prepared and based on the results technical and economic aspects were investigated to determine opportunities for CO2 capture and storage focusing on MOL’s facilities;
  • In 2009 a consortium was established with the participation of MVM (Hungarian Electricity Works), MERT (Mátra Power Station Plc.), MOL and ELGI (Eötvös Loránd Geophysical Institute), with the purpose of investigating specific opportunities for CO2 capture and storage for the new power station block at the future Mátra Power Station;
  • The consortium continued its operations and prepared a pre-feasibility study in June on capture in MERT, then pipeline transmission and storage in some depleted MOL gas fields;
  • The consortium (including Matra Power Plant and MVM) ceased cooperation at the end of 2010 because MVM made a decision to cancel the plan to build a new lignite fired power plant block in Matra PP in the near future thus obviating the need for a CCS project to be accomplished within the frame of the consortium.
  • The EU (European Union) issued an invitation to tender in November 2010 for support for CO2 capture and storage demonstration projects. However, with the current cessation of the consortium there are no possible candidates for partnership in Hungary with whom we are able to submit a Hungarian bid.
  • The pre-feasibility study regarding CO2 storage in depleted gas fields finished in 2010. All the necessary calculations have already been carried out by a MOL Upstream expert team as regards transport and storage. The pre-feasibility study regarding CO2 storage in deep saline aquifers is still being carried out and will be finished in the first half of 2011.
The Hungarian Government and the Norwegian Embassy made a joint statement that the Norwegian Fund is about to decide on the possibility of a Norway-Hungarian R&D CO2 storage project in Hungary. MOL is expected to be involved into this project.
