D7.4 – Scenarios Beyond REWARDHeat: Energy, Environmental, Economic and Societal Impact Assessment

This report is the deliverable 7.4 of the H2020 project REWARDHeat. This report relates on the impacts of the REWARDHeat solutions developed, in terms of the energy, environmental, economic and societal aspects in the demonstrator networks and on a large scale in the urban or municipal DHC system surrounding. 7 cities in Denmark, France, Croatia, Sweden, the Netherlands, and Italy are evaluated, including Albertslund, LSSM (Toulon), Topusko, Helsingborg, Mölndal, Heerlen (Brunssum) and Milan. The assessment of impact scenarios builds on existing knowledge and approach within energy systems modelling and social cost benefit analysis.
The overall approach to the elaboration and assessment of impact scenarios is to see the REWARDHeat technologies and systems as part of a wider Geographical and energy system context. Within this context they are upscaled from demo site level to a city-wide or municipality-wide level based on an evaluation of their expansion potential. As the first step, performance indicators (KPIs) are defined that make it possible to capture, evaluate and compare the upscaled REWARDHeat solutions as part of the wider energy system. The KPIs are, therefore, defined at the energy system level. In the second step, the upscaled REWARDHeat technologies are assessed in the larger, future (urban/municipal) energy system they are situated in, by means of energy systems analysis using EnergyPLAN. For this, energy system scenarios are created. Third, the economic and societal impacts of the energy system scenarios are evaluated.
