Sustainable heating processes are a focus of research and development activities at the HTL. This includes issues such as the conversion of thermal processes to CO2-neutral operation, for example by using green hydrogen as a heat source, or the general switch from gas firing to electric heating. In addition to these approaches, which are usually accompanied by investment requirements for the user, the HTL also offers a systematic methodology for optimising thermoprocesses that does not require any structural changes to existing thermoprocess plants.
