Abstract
Amsterdam planlægger at udfase naturgas til opvarning af bygninger og sigter mod et fossilfrit varmesystem i 2050. Dette speciale undersøger, hvordan overgangen kan gennemføres i praksis. Det analyserer driften af et varmesystem baseret på vedvarende energi i 2050 under tre scenarier: et referencescenarie, et vedvarende scenarie uden termisk lagring og et vedvarende scenarie med termisk lagring (opbevaring af varme til senere brug). Studiet ser også ud over teknologien. Med den såkaldte Multi-Level Perspective—et rammeværk, der ser på, hvordan teknologier, politikker, markeder og sociale normer udvikler sig sammen—diskuteres de mekanismer, der driver sociotekniske forandringer. Teknisk viser analysen, at varmesektoren kan fungere uden naturgas, hvis flere tiltag kombineres. Det omfatter udbygning af fjernvarmenettet (bydækkende rør, der leverer varme), udskiftning af kraftvarmeværker (CHP) med biomassefyrede enheder, større udnyttelse af overskudsvarme samt tilføjelse af elektriske varmepumper, en elkedel, en biogasfyret kedel, solvarme og termisk lagring. Tilsammen kan disse løsninger dække byens varmebehov og udfase naturgas.
Amsterdam plans to phase out natural gas for heating buildings and aims for a fossil-free heating system by 2050. This thesis examines how that transition could work in practice. It analyzes how a renewable-based heating system for 2050 would operate under three scenarios: a reference scenario, a renewable heating scenario without thermal storage, and a renewable heating scenario with thermal storage (storing heat for later use). The study also looks beyond technology. Using the Multi-Level Perspective—a framework that considers how technologies, policies, markets, and social norms evolve together—it discusses the mechanisms that drive socio-technical change. On the technical side, the analysis finds that the heat sector can operate without natural gas if several measures are combined. These include expanding the district heating network (citywide pipes that deliver heat), replacing combined heat and power (CHP) plants with biomass-fueled units, making greater use of surplus heat, and adding electric heat pumps, an electric boiler, a biogas-fired boiler, solar thermal energy, and thermal storage. Together, these options can meet the city’s heat demand while phasing out natural gas.
