District heating from data in Dublin

In the Tallaght area in Dublin there is a datacentre that needs cooling. At the same time the surrounding households need heating. The first part of a district heating grid and three large heat pumps converting the waste heat to district heat temperature are already in place. But only a small part of the waste heat is utilized today.

In this project the TEN21 toolbox is used to analyse a possible expansion of the district heating grid, by investigating which buildings are feasible to connect and which other heating options the waste heat from the datacentre is competing against. TEN21 energy system modelling tool is used to create scenarios exploring different future options.

TEN21 is also supporting with legal advice of how to structure future contracts with heat suppliers and takers. All is in close dialogue with the local authorities to secure relevant analysis and solutions.

The Tallaght Dublin project is funded by the European City Facility, Horizon 2020.

A climate neutral Kiruna in 2025!

The mine in Kiruna is the world’s largest underground iron-ore mine and has been an engine for wealth in the town since 1898. Now the waste heat from the mine can be the engine behind a sustainable district heating system.

The current district energy system of Kiruna includes only a small share of waste heat from the iron mine, but the amount of waste heat that can be delivered to the city’s district heating system is increasing.

The project ‘A climate neutral Kiruna in 2025’ focuses on the optimized use of waste heat in the heating sector. An energy system model has been developed for the city to assess the utilization of waste heat from the mine. The model makes it possible to investigate the role of large-scale thermal energy storages and other required investments for the heating sector in the long term.
