Abstract
Dette speciale undersøger, hvor stor en del af varmebehovet i Tysklands Bioenergiedörfer (BED) fjernvarmesystemer der kan dækkes af solvarmebaseret fjernvarme (Solar District Heating, SDH) – store solvarmeanlæg – og hvordan det kan understøtte deres omstilling. Studiet bygger på en tredelt analyse. For det første estimeres det teknisk-økonomiske potentiale for at tilføje SDH. Analysen peger på 74 egnede landsbyer og et potentiale på efterspørgselssiden på ca. 240.000 m2 solfangere, svarende til omkring 121 mio. EUR i anlægsomkostninger. Der skelnes også mellem to grupper af BED baseret på tekniske specifikationer på efterspørgselssiden. For det andet vurderes tilgængelige lokale biomasserester inden for en radius på 50 km. Disse ressourcer bør indgå i planlægningen af vedvarende energisystemer i landområder. For det tredje belyses de teknologiske, organisatoriske, beslutningsmæssige og økonomiske barrierer, som i dag begrænser anvendelsen af SDH i BED, samt mulige tilgange til at afhjælpe konkrete barrierer. Samlet set peger resultaterne på, at SDH kan bidrage væsentligt til BED-fjernvarme, hvis planlægningen integrerer lokale biomasseressourcer, og centrale barrierer håndteres systematisk.
This thesis examines how much of the heat demand in Germany's Bioenergiedörfer (BED) district heating systems could be covered by Solar District Heating (SDH)—large solar thermal collectors—and how this could support their transition. The study uses a three-part analysis. First, it estimates the techno-economic potential of adding SDH. The analysis identifies 74 suitable villages and a demand-side potential of about 240,000 m2 of solar collectors, corresponding to around 121 million EUR in capital costs. It also distinguishes two groups of BED based on technical specifications on the demand side. Second, it assesses the availability of nearby biomass residues within a 50 km radius. These local resources should be factored into the planning of renewable energy systems in rural areas. Third, it examines technological, organizational, decision-making, and economic barriers that currently limit the uptake of SDH in BED, and outlines possible ways to address specific barriers. Taken together, the results indicate that SDH could make a meaningful contribution to BED district heating if planning integrates local biomass potentials and if key barriers are systematically addressed.
