CHOREN has its headquarter in Beijing and operates further branches in Hong Kong and Germany. The German company CHOREN Industrietechnik GmbH is based in Dresden, Saxony, near the well-known gasification plant in Schwarze Pumpe. This operated according to the world-famous patent for a modern energy technology (GSP), which was developed in the former German Fuel Institute (DBI).

The enterprise CHOREN was founded by former employees of the research and development department of the German Fuel Institute (DBI). In addition to the experts from DBI, employees of the Schwarze Pumpe gasification plant and the Royal Dutch Shell Group were also involved in the development. The origin of the name CHOREN is based on the connection of:
