RESTORE focuses on making district heating and cooling networks 100% renewable through an innovative concept. The project developed a reversible organic Rankine cycle system (rORC) capable of storing renewable energy in a thermochemical energy storage. The storage is discharged to generate...

Numerous measures have been taken in recent years to achieve climate protection targets in Germany’s building sector. With the newly established Ariadne German Heating and Housing Panel (GHHP), the prerequisite for a well-founded evaluation of the effectiveness, distribution effects, and...

The recent energy crisis in Europe has underlined the importance of a fast replacement of fossil fuels like natural gas by green energy carriers. Great hopes for quick decarbonisation mostly rest on two technologies, hypothesized to form a "perfect match": Combined heat and power (CHP)...

Urban manufacturing is increasingly discussed as a contributor to sustainable urban development, particularly through its potential to supply industrial waste heat for district heating networks (DHN). This paper examines whether urban manufacturing in Germany can provide a meaningful source of...

I examine the pricing behavior of municipal and private firms in the unregulated Swedish district heating market, characterized by geographically bounded local monopoly networks. Conditional on exogenous cost factors, private firms charge on average seven percent higher prices compared to their...

Using industrial excess heat for residential heating can increase energy efficiency and thus be part of the solution to achieving the EU's climate targets. However, industrial plants are often located in industrial areas and thus away from residential areas. Therefore, the excess heat has to be...

The district heating system in Heerlen, the Netherlands makes use of an innovative approach: using mine water from a former coal mine as a geothermal heating source and for energy storage. The system is one of the first so-called 5th generation district heating and cooling (5GDHC) grids, an...
