Abstract
Dette speciale undersøger, hvordan Tysklands energisystem i 2030 kan optage overskuds-el fra variable vedvarende kilder ved at koble elsektoren med varme og transport. Med EnergyPLAN opstilles et referencesystem for 2030, hvorefter fire tværsektorielle cases tilføjes med brug af varmepumper, termisk energilagring og elbiler (inklusive vehicle-to-grid-muligheder). Resultater fra reference og tværsektor-cases sammenlignes på tre nøgletal—CO2-udledninger, samlede årlige systemomkostninger og kritisk overskuds-el—efterfulgt af følsomhedsanalyser, der sænker teknologipriser og øger kapaciteterne af varmepumper og elbiler. Arbejdet bygger på litteraturstudier og ekspertinterviews. Uddraget præsenterer ikke kvantitative resultater, men studiet er tilrettelagt til at vurdere, om tværsektoriel anvendelse af overskuds-el kan reducere omkostninger, sænke udledninger i tråd med klimamål og mindske nedregulering og eksport ved at udnytte elektricitet i det hjemlige varme- og transportforbrug.
This thesis investigates how Germany’s 2030 energy system could absorb surplus electricity from variable renewables by coupling the power sector with heating and transport. Using the EnergyPLAN tool, a 2030 reference system is established and four cross-sector integration cases are added that deploy heat pumps, thermal energy storage, and electric vehicles (including vehicle-to-grid options). Outputs from the reference and cross-sector cases are compared on three metrics—CO2 emissions, total annual system costs, and critical excess electricity production—followed by sensitivity analyses that reduce technology prices and expand heat pump and EV capacities. The work is informed by a literature review and expert interviews. While the excerpt does not report quantitative results, the study is designed to evaluate whether cross-sector use of surplus electricity can cost-effectively lower system costs, reduce emissions in line with climate goals, and decrease curtailment and exports by utilizing electricity in domestic heating and transport.
