Germany: Holcim, E.ON Energy Infrastructure Solutions and Orcan Energy have launched a large-scale waste heat recovery project at Holcim’s Dotternhausen cement plant to capture 10MW of unused heat from kiln exhaust gases. The recovered heat will supply internal processes, potential district heating networks and power generation via Orcan Energy’s eP1000 Organic Rankine Cycle (ORC) system. E.ON is responsible for the planning, construction, financing operation and maintenance of the plant as part of an Energy-as-a-Service model. This is intended to present no initial investment costs for Holcim.
Holcim South Germany plant manager Dieter Schillo said “This project marks an important milestone on our path to decarbonising cement production. The smart use of industrial waste heat not only reduces our Scope 2 emissions, but also strengthens our role as a pioneer in sustainable building materials.”
