Waste heat recovery

Waste heat recovery is the transfer and use of residual heat from a thermodynamic cycle, industrial process or a different heat source such as the operation of computers in a data center, which would otherwise be discarded into the environment. This residual heat with high operating temperatures can be used as useful heat at lower temperatures in the same system (preheating) or transferred to an adjacent system for further energy generation such as Rankine cycle for electricity generation and district heating network for space heating.

List of projects where this technology is being implemented.

NEXT-BUILDINGS

The NEXT-Buildings project focuses of low energy buildings also called active houses, which are not only buildings, but active components in the overall integrated energy systems. The target is to demonstrate affordable solutions for social housing and revitalisation of town areas. The solutions...

GrowSmarter

GrowSmarter aims to stimulate city uptake of smart solutions by using the three Lighthouse cities Stockholm (Sweden), Cologne (Germany) and Barcelona (Spain) as a way to showcase 12 Smart City solutions: from advanced information and communication technology and better connected urban mobility, to...

EE-HIGHRISE

The overall objective of the EE-HIGHRISE project was to demonstrate and validate new technologies, concepts, and systems used, in order to test and assess the technological and economic feasibility of innovative energy solutions in the high rise demo buildings in contributing to the EU energy and...

CELSIUS

To increase energy efficiency in EU, CELSIUS helps cities across Europe to develop secure, affordable and low carbon district heating and cooling solutions that form part of the city's wider energy system. The focus is on maximising the use of waste heat or secondary heat within a city by capturing...

BEEM-UP

BEEM-UP aimed to demonstrate the economic, social and technical feasibility of retrofitting initiatives, drastically reducing energy consumption in existing buildings, and paving the way towards massive market uptake. BEEM-UP involved building owners at three sites in France, Sweden and the...

CELSIUS Site Cologne

In order to create a district-wide energy network in Cologne, Active Network Management (ANM) integrates decentralised energy generation and district heating systems with the electricity distribution network. The objective of the ANM scheme is to inform the models that are used to assess if...

CELSIUS Site Gothenburg

In Gothenburg a large amount of waste heat, from both waste incineration and industries, is used in the district heating system. There is also heat pumps taking care of the heat in sewage and plants using bio fuels such as wood pellets, wood chips and bio oil. There is also a district cooling ...

GrowSmarter Site Stockholm

Sweden’s capital city Stockholm has been working on climate change mitigation and adaption since the 1990s. The city is a real frontrunner, with well implemented climate action plans and pioneering policies to ensure it meets its ambitious environmental targets. The carbon dioxide emissions have...

BEEM-UP Site Alingsas

Brogården in Alingsås is an area of multi-dwelling buildings built in 1971-1973. The area comprises a total of 300 flats, divided into 16 houses with 2-4 floors each. All flats have a balcony or a patio. The Brogården area is currently undergoing an extensive renewal, which started in the spring of...

NEXT-BUILDINGS Site Helsingborg

In Helsingborg there is a very ambitious climate action plan, where the city as a whole has already reduced its CO2 emission by about 88% compared with 1997 level and the share of fossil fuel is now less than 20%. The goal is to become totally CO2 neutral or even to export CO2 neutral energy to...
