RIJEKA

Overview: Rijeka is Croatia’s third-largest city and home to the country’s largest port, adding economic relevance to the city. It has a population of approximately 110.000 inhabitants.

Current DH System: As a reflection of this economic might, the city started to invest in its district heating system already in the 1960s. Today, more than 15km of pipelines supply heat to 9400 households and 150 commercial users.

What work will ENABLE DHC do: One of the project objectives is to end Rijeka’s dependence on fossil fuels for heat generation. Today, 90% of the heat in the city’s district heating comes from natural gas. The project will investigate the use of waste heat from sewage water and large-scale solar fields to substitute fossil fuels. This will be coupled with heat storage tanks and retrofitting of the grid, increasing efficiency. Additionally, there are plans to connect parts of the network, facilitating its management.
