Revisiting the management of stationary fuel supply security and gas diversification in Hungary

This paper aims to assess the security of stationary fuel supply in Hungary by applying the three-dimensional approach, encompassing availability, affordability and sustainability. The main focus is on primary energy fuels in relation to electricity, but the approach is also applied, in part, to electricity itself. It is shown how select influencing factors affect the choices made from among security of supply dimensions. Although providing a source-by-source review, special attention is paid to nuclear energy and natural gas. For a long time, natural gas has been the fuel that Hungary is particularly sensitive to in terms of security of energy supply. Thus, gas diversification has become a key issue, analysed here also by using my own gas diversification scheme. I find that considerable progress has been made in this area. However, along with the 2014 decision on the construction of new units at the Paks Nuclear Power Plant (Paks II), aimed at achieving self-sufficiency in Hungarian electricity supplies, the energy agenda has changed considerably. With Paks II, Hungary’s dependence will both decrease and increase – as new types of risks emerge. In such circumstances, a Nuclear–Solar/Biomass–Natural Gas concept of the electricity mix seems to be emerging in Hungary.
