- 2. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 District Heating Traditional urban heating supply • Large scale production plants produces hot water for heating and tap water • The hot water is distributed to each building and circulated back to production unit for reheating again in a closed system • Each building have a secondary distribution system for heating and tap water • District heating system in Stockholm consists of 3.000 km of pipes and 180 million litres
- 3. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 Open District Heating Turning waste into a heating source • Urban environments generates waste heat due cooling needs such as data center's, grocery stores and industries • Open District Heating supports reuse of waste heat into a energy source for heating and tap water • Open District Heating is a business model that enables third parties to gain value of its waste heat by deliver the energy into the district heating network • The deliveries function as small scale production units distributed on the system and other production can by reduced or avoided in favor for waste heat and by that an improved overall production mix
- 4. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 Heat recovery is today an essential part of the energy system – and its share increases appr 20% p.a. Two measures within Grow Smarter • During 2019 a total amount of over 3500 MWh waste heat is prospected to be recovered corresponding heating of appr 300 apartments • Corresponding a reduction of 230 tCO2 emissions in the production mix Heat recovery in Stockholm • During 2019 a total amount of over 130 000 MWh waste heat is prospected to be recovered corresponding heating of appr 11000 apartments • Corresponding a reduction of 8500 tCO2 emissions in the production mix
- 5. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 Lessons learned and next step • Long and complex implementation processes due to relatively large investment and installations for each supplier • Heat recovery is an important piece to be energy smart within the growing digitalization and data center segment • Collaboration with other parties enables large scale heat recovery • Customer pushing heat recovery concept to other geographies and cities

Editor's Notes
- Now a few words about our main and largest SmartCity Cologne Project: GrowSmarter. Together with the cities Stockholm and Barcelona, Cologne is a lighthouse city in this Horizon 2020 project. The vision is transforming cities for a smart, sustainable Europe. In a rapidly urbanising world cities need to become smarter to respond to citizen needs and to reduce their environmental footprint. GrowSmarter brings together cities and industry to integrate and demonstrate ‘12 smart city solutions’ in energy, infrastructure and transport, to provide other cities with valuable insights on how they work in practice and opportunities for replication. As cities face similar challenges, the idea is to create a ready market for these smart solutions to support growth and the transition to a smart, sustainable Europe.
- We follow an integrated project approach. As mentioned, the three areas of implementation are energy, infrastructure and transport. Each of the lighthouse cities coordinates one of these topics.
