In addition to the development of the LNG filling network, Hungary is responsible for the further extension of the CNG filling station network as well in conformity with Directive 2014/94/EC. On the basis of the expectation of the European Commission, Hungary must develop a filling station network of appropriate frequency by 2020. Currently nine public CNG filling stations are available for the users and others are being constructed. According to the calculations of MGKKE, however at least 100 CNG filling stations would be needed in Hungary in order to fulfil the expectations of the European Union and the strategic objectives. Nevertheless the difficulties of the CNG technology and the legal permitting proceedings provide an outstanding opportunity for the widespread development of LNG. The PAN-LNG Project developed by MGKKE therefore makes the implementation of the Directives of the European Commission faster also contributing to the more effective expansion of the use of alternative fuels.
