ENVIRONMENTAL AND ECONOMIC IMPACT IN REGIONAL ENERGY INTEGRATION
Abstract
The paper highlights the complexity of multi-energy integration (electricity and heat) in a regional economic system, by using the vectors represented by green hydrogen, green certificates and methanization of captured carbon dioxide, for a local market mechanism. The scale of application can go down to residential areas of energy self-producers. Regional multi-energy systems take into account the use of fossil fuels (at least methane), along with biomass for the production of electricity alongside that from renewable sources. Current multi-energy systems include the use of the combustion concept for the fuel mixture formed by and (HCNG). Part of the methane can be represented by synthesis, formed by the chemical relationship with (Sabatier reaction). This way, an energy recovery is achieved in the form of a synthesis fuel for captured , eliminating storage problems. The paper also presents the technological differences between the methanization of pure carbon dioxide, compared to that found in the combustion gases discharged directly from energy installations, innovative solution proposed by the authors. General constructive-functional and economic aspects relating to the existing methanizers at the current technological stage are also presented. Zonal energy integration addresses any region producing energy from a set of sources, which is to become economic in an independent operation of state energy systems. Economic simulation and operation systems are very complex, with generally recognized operators mentioned in the paper.
