The Dresden-based Sunfire GmbH is a key enterprise for Saxony’s hydrogen economy: The company develops and produces particularly efficient high-temperature electrolyzers (SOEC) as well as proven alkaline systems which break down water into hydrogen and oxygen with the help of renewable electricity.

Energy recycling, so to speak, is the core business of the WätaS Wärmetauscher Sachsen GmbH corporation from Olbernhau. The company develops concepts and produces systems which permit energy to be used multiple times after it has been generated by recovering energy from waste heat.

One of the world’s most modern district cooling networks is operated by the eins energie in sachsen GmbH & Co. KG in Chemnitz. The requisite cooling energy is provided by absorption chillers and thermal energy storage systems.

Based on the idea of using waste heat from servers for heating, Cloud&Heat Technologies GmbH has developed concepts for energy-efficient data centers and secure cloud solutions.

Together with its subsidiaries DBI Gas- und Umwelttechnik GmbH in Leipzig and DBI Gastechnologisches Institut gGmbH Freiberg, the DBI Group covers the entire gas supply value creation chain, ranging from production to storage and grid transportation all the way to utilization of renewable energies.
