Thermal Energy Storage System Design

Below, some of our present projects are described.

In this project the transportation of thermal energy using advanced storage technologies, like PCM, is further examined. Here, the focus is on the providing knowledge on the characteristics of potential receiving heat by way of truck, train and boat. Several cases are examined like a district energy heating plant receiving industrial waste heat, or a small municipality receiving heat from a larger utility combined heat and power plant. This project is financed by the Swedish District Heating Association and the Energy Agency via the R&D program Fjärrsyn.

This project is a collaborative effort between Ecostorage Sweden AB, SSAB Oxelösund, and Climatewell AB. The aim is to develop systems for effective transportation of thermal energy over distances, and between places where district heating is not cost-effective. When utilizing advanced thermal energy storage technology and transporting energy by way of truck, train, or boat, there is a large potential to increase the use of industrial surplus heat for heating and cooling in the built environment. Today, industries are often too far away from large heating and cooling demands which means that several TWh/year of good quality surplus heat remains unused and is wasted. The project is co-financed by the industrial partners and the Swedish Energy Agency.

Matching energy supply with to the energy demand can be overcome by the incorporation of proper energy storage systems. PCMs are interesting because of the large amount of heat absorbed at a constant temperature. Ecostorage Sweden AB participate in a European Cooperation in the field of Scientific and Technical Research — COST— with the aim of accelerating the long-term development of PCM storage systems by way of characterization and simulation of the next generation modified hybrid PCMs.
