Development

Norsyn equals foresight. Within that lies our vision to develop. 

The development projects listed below are our contribution to future solutions in energy and construction. They involve: low-temperature district heating, thermonet, drones, tank scanning, and hybrid energy networks . 

It’s our pursuit to improve what we know and explore what we don’t, so together we can create a more sustainable future

Thermonet

Thermonet is a district heating system specifically designed for areas where it is not profitable to establish a traditional system, for example in areas with few buildings. 

With thermonet or cold district heating, as it is also called, energy is drawn from existing energy sources, such as geothermal energy, and resources are utilized in this way. 

Together with Lind & Risør, we have developed the largest system of this type in Denmark.

New thermostats

Temperature optimization is an important tool in the effort to save energy. By lowering the return temperature in radiators, the overall operation can be optimized – without compromising the comfort of the respective buildings. 

We have designed a new thermostat that will optimize the energy yield of district heating in urban areas. The thermostat has been developed in collaboration with Danfoss, DTU, Frederiksberg Forsyning, the Danish Energy Agency, and EUDP. The thermostat is marketed by Danfoss and will be part of future constructions and retrofits.

Drones

In connection with the inspection and scanning of buildings, district heating tanks, district heating expansion areas, etc., we often use drone technology. The drone is a significant inspection tool and an important part of our daily work. It is used, among other things, to take thermal images and for ongoing orthophotos of expansion areas. Thermal images are included in condition assessments of buildings, tanks, and pipeline networks, where we can, for example, get an indication of the condition of individual pipes and thus assess the need for maintenance and/or replacement.

TS3 - Hybrid energy networks

This involves the development of a new concept to combine district heating and district cooling in a so-called Double Loop Network.

  • Grundfos 
  • Aalborg University (AAU)

Tank scanning

At Norsyn, together with international specialists, we have developed a technology to scan district heating tanks to estimate the tank’s maintenance needs. A district heating tank is a PtX technology (Power-to-X) that has existed since the 1980s. 

By cutting through the outer steel layer and insulation at various points on the tank, we can insert scanners that send small vibrations through the entire inner structure. The individual measurements allow us to simulate data of the entire tank through calculations. This gives us a picture of where the tank needs to be reinforced and repaired to last many more years. 

The tank normally has a lifespan of 20-30 years, after which it is typically decommissioned, but with tank scanning, it is possible to simulate the current condition of the tanks and assess what is needed for them to last longer.
