Deep Geothermal Heat Networks: Lessons from Global Case Studies

Geothermal heat networks offer a reliable, renewable, and adaptable solution for heating needs across climates and city types. The six case studies in this White Paper provide evidence that geothermal systems—when properly planned and managed—can deliver long-term economic, environmental, and social benefits. Together, they form a global roadmap for and important class of climate-resilient heating infrastructure in the 21st century.  The White Paper identifies cross-cutting themes and key success factors that for a primer for any stakeholder considering a geothermal heat network development.
