[Video] The ReUseHeat Project Explained by Project Coordinator, Kristina Lygnerud
Alessandro Provaggi (Euroheat & Power) and Kristina Lygnerud (IVL) give you an overview of the recently launched H2020 ReUseHeat project.
Decarbonising with Unconventional Sources
Metro Systems and Hospitals Will Heat our Dense City Centres
Let’s not waste heat! Let’s communicate!
We would not throw food away, so why would we waste freely available heat? This is the simple philosophy that leads the ReUseHeat project, kicked off in October 2017.
Madrid
The City of Madrid Madrid is the capital of the Community of Madrid and Spain. It is the largest city in the country with 3.2 million inhabitants, although if we include the population of the Madrid metropolitan area, it reaches 6.3 million. Madrid is the 5th most important leading centre of commerce in Europe.
Brunswick
The City of Brunswick Brunswick (Braunschweig) is the second largest city in Lower Saxony, Germany, with 250,000 inhabitants. The region of Brunswick is one of the leading European regions with regards to spending on research and development. The city prides itself to be a hub of versatile industry expertise, including technology and innovation, energy and
Nice
The City of Nice With 344,000 inhabitants, Nice is the 5th biggest city in France. Nice is situated in the French Riviera and is one of the top tourist destinations in Europe, attracting around 5 million visitors per year. The Metropole Nice Côte d’Azur, an intercommunal structure made up of 49 cities around Nice, has
Waste Heat?
At first sight, the concept of waste heat appears easy to grasp, but is everything as easy as it seems? Have you also heard of “excess heat”, “surplus heat”, “recoverable heat”, “waste-to-energy”, “recovered heat”? Are these terms equivalent or do they cause a degree of confusion? Below you will find a non-exhaustive dictionary. In the ReUseHeat
District Heating & Cooling
District heating and cooling is a proven solution for delivering heating, hot water and cooling services through a network of insulated pipes, from a central point of generation to the end user. District heating and cooling networks are also referred to as heat networks or district energy networks. They are suited to feed in locally
Facts & Figures
District energy & waste heat If the urbanisation trend continues and appropriate investments are in place, almost half of Europe’s heat demand could be met by district energy by 2050. There is on average 3 times more renewable and excess heat available than is required to meet high levels of district energy supply A transition to
Data Centres
In 2010, data centres world-wide used about 350 TWh of electricity. It is just over 1% of the world’s total electricity use and it is constantly growing. Most of the power consumed by the Information Technology (IT) equipment is converted into waste heat, which must be removed to avoid damage to the equipment. The energy
Underground Transport Systems
On a hot summer day, a ride on the metro can be an unpleasant experience with stiflingly hot metro systems and trains. What is the reason for that and why don’t we reuse this heat? Metro trains generate excess heat when operating. The electric motors create heat due to their electrical and mechanical functioning at
Waste Water Management
Waste water management systems exist in every city and could be exploited to heat buildings. Waste water systems promise major heat recovery potential. The temperature of waste water ranges from 10 to 15°C on average, and can go even up to 20°C during summertime. This guarantees an adequate heat source for the operation of heat
Tertiary Buildings
Tertiary buildings in urban areas such as offices, schools, supermarkets, logistics centres or hospitals are a significant source of heat which could be recovered. All of them require some kind of cooling or air conditioning, e.g. the fridges and storage rooms of supermarkets, surgery rooms in hospitals or fridges and walk-in coolers in restaurants. During
Other Sources
There is a huge untapped potential of waste heat across the world, reflected in very low utilisation levels.

ReUseHeat quantified EU28 urban waste heat potential
The ReUseHeat report Accessible Urban Waste Heat shows a significant heat recovery potential from unconventional excess heat sources. Approximately 1.2 EJ (or 340 TWh) per year are possible to recover from data centres, metro stations, service sector buildings, and waste water treatment plants. This corresponds to more than 10 percent of the EU’s total energy
ReUseHeat featured in Hot Cool 2 2019 magazine
Urban waste heat recovery is a key to smart cities but to get there, many challenges need to be managed. The industry needs to go beyond its tradition of technical orientation and grasp the window of opportunity of the low temperature heat recovery. The opportunity allows the companies stepping over the threshold of technology to
Join us at the ReUseHeat policy workshop on 2 October 2019!
The heat being wasted across Europe could cover 100% of our buildings’ needs. District heating and cooling networks can utilise excess heat available from various sources, including excess heat from urban facilities (i.e. data centres, sewage collectors, cooling systems of tertiary buildings, underground stations). However, due to some regulatory challenges, lack of large-scale replicable demonstrators

Policy Webinar: How can waste heat recovery help decarbonise cities? Best practices & policy recommendations
The EU produces more waste heat than the demand of its entire building stock. Conservative estimates suggest that industrial waste heat could cover at least 25% of district heating generation. Moreover, there is significant heat recovery potential from unconventional waste heat sources, i.e. waste heat from data centres, metro stations, service sector buildings, or waste-water
