Urban Waste Heat Recovery
|
|
As we have heard before, there is enough residual heat in Europe to potentially heat its entire building stock. Much of that heat can be found right in the heart of the cities: metro and sewage systems, hospitals and datacenters, among others. This is accentuated by developing technologies that make it easier to recover energy from lower temperature sources.
With this in mind, this month we focus on urban waste heat recovery. Below you will find an article promoting the use of residual heat form data centers, and this month’s Celsius Talk will highlight the first results and replicability potential of the ReUseHeat project’s demo site in Madrid where they recover waste heat from a hospital.
Join us on Thursday June 17 at 11:00 CET to take part in more interesting discussions on the subject.

Cities Manifesto for Fossil-Free Heating and Cooling
What cities need from the EU & Member States to implement the Green Deal and accelerate the heating and cooling transition.
3 years after the Celsius community pledged to bring sustainable heating and cooling to the heart of their cities and accelerate the energy transition, great progress has been made. However, in view of the upcoming “Fit for 55” EU legislative package, it will be essential to keep the bar high on energy and climate action and enable cities to continue their progress.

Data Centers, powering the future in many ways

What do green and digital have in common? - Waste heat! These two words have been coupled a lot to talk about the transition to sustainable societies with the EU Green Deal or in the context of the recovery from the global pandemic. They define the aspirations of cities and their citizens, combining two concepts that could seem incompatible in the current context.

The Celsius initiative, a European project that lives on
Before we take a break for the summer, we would like to take a moment and reflect on how much the Celsius Initiative has grown and evolved since it started as a FP7 Framework project between 2013 and 2017.
Our mission is stll to support cities in their energy transition, but our approach has changed.

Excess heat from the London Underground provides district heating in Islington, where LO2 and LO3 are two of London’s demonstrators.

The demonstrators in Cologne recover heat from sewage water and use it in decentralized local heating networks.

In this text you can learn about waste incineration and Waste-to-energy (WtE). It also describes the method’s role in recycling and its part in a circular economy.

Responding to the ever-increasing energy demand while reducing carbon emissions and their climate impact will require energy systems to be even more integrated, flexible, and innovative. The use of renewable energy sources is key, though given their variable nature they generate difficulties in balancing the production and demand. Hence, combining multiple energy carriers can provide the system with the needed flexibility – the heat and electricity sectors can complement each other and facilitate a more efficient use of renewables and waste heat. This sector integration has a huge potential yet a long way to go.
Thus, in collaboration with the Flexi-Sync and MAGNITUDE projects, May 2021’s Celsius Talk addressed how to improve flexible system integration for thermal energy networks.
