The role of the Emission Trading Scheme in the decarbonization of existing district heating systems
Get PDFThe FitFor55 legislative package sets ambitious targets to make Europe the first climate-neutral continent by 2050. Within it, the EU Emission Trading Scheme is mandatory for energy operators with an installed capacity higher than 20 MW, calculated by considering units with a rated thermal input under 3 MW. The paper highlights the impact of the Emission Trading Scheme on the investment choices made by district heating systems operators, considering both current regulations and the potential extension of the Emission Trading Scheme to encompass lower energy capacities. The analysis concerns the simulation of four revamping scenarios (two fueled by natural gas and two partially by renewables) within an existing district heating system located in Italy. The economic analysis shows that an extension of the Emission Trading Scheme alone is not effective in hindering scenarios based on natural gas production. A reform of the power exchange market is necessary to drive decarbonization and encourage investment in renewable generation plants

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
