Unfortunately, the reliable, efficient operation of utility systems is often taken for granted, and they receive little engineering attention. This is perhaps understandable, since these systems play a supporting role to a generally more complex, attention-demanding process. However, utility systems are inherently close to the energy consumption of a facility, and their correct operation is critical to reduce energy costs and CO2 emissions of a process.

Electrified Thermal Solutions (ETS) has taken a new approach to industrial heating through its JouleHive thermal battery, which can achieve near-flame temperatures continuously without degradation. The heart of JouleHive is the company’s proprietary electrically conductive fire bricks (E-bricks).

It is based on modernizing blast-furnace technology with moderate investments. The process was developed by KIT’s Institute for Chemical Technology and Polymer Chemistry (ITCP), in cooperation with the SMS group and its subsidiary Paul Wurth S.A., and KIT’s startup omegadot software & consulting GmbH. The process was demonstrated and validated at a pilot plant (photo) at Dillinger Hüttenwerke, Saarland.
