D&S will hold a 51% share of Geysir Europe, while Geysir Green Energy will hold the remainder.
Geysir Europe is one of the largest European geothermal players, with development claims on 13 geothermal sites across the northern German Alps and upper Rhine valley through its subsidiaries Exorka and Enex.
Geysir Green Energy and D&S say their complementary experience will give them a broad grip on Germany’s geothermal-energy sector.
