Abstract
Dette projekt analyserer og designer, hvordan der kan produceres elektricitet til bæredygtige off-grid huse, der udvikles som en del af Projekt Grobund. Først introduceres off-grid elsystemer og praktiske muligheder for lokal elproduktion. Derefter estimeres energibehovet for et konceptuelt off-grid hus. For at undersøge mulighederne for at omdanne varme til elektricitet testes termoelektriske elementer—komponenter, der omdanner temperaturforskelle direkte til strøm—monteret på en masseovn, både i laboratoriet og i felten. Et Excel-baseret Off-grid Simulationsværktøj udvikles til at modellere balancen mellem elforbrug, produktion fra solceller og en vindmølle samt batterilagring. På baggrund af disse indsigter foreslås et energisystem til off-grid husene i Projekt Grobund. Afslutningsvis gennemgår rapporten dansk lovgivning, der kan påvirke off-grid levevis, med en detaljeret drøftelse af forholdene på den tiltænkte placering.
This project analyzes and designs how to generate electricity for sustainable off-grid houses being developed within Project Grobund. It begins with an overview of off-grid electricity systems and practical options for local power production. It then estimates the energy needs of a conceptual off-grid house. To explore heat-to-electricity options, the project tests thermoelectric elements—devices that convert temperature differences directly into electricity—mounted on a masonry mass oven, both in the laboratory and in the field. An Excel-based Off-grid Simulation Tool is developed to model the balance between electricity demand, generation from photovoltaic panels and a wind turbine, and battery storage. Based on these insights, an energy system is proposed for the off-grid houses in Project Grobund. Finally, the report reviews Danish legislation that may affect off-grid living, with a detailed discussion of conditions at the intended location.
