Hans-Horst advocated for an open process simulation environment at the FOCAPD 94 conference as well as in a paper co-authored with colleagues of major German chemical companies, presented at ESCAPE 5 in June 1995.
With his BASF colleague Harmut SCHOENMAKERS, his paper presented at ESCAPE-8 in May 1998 (Brugge, Belgium) recognized that CAPE-OPEN was progressively fulfilling the need perceived by the chemical industry that process simulation software should interoperate. This paper helped communicating on the outcome of the CAPE-OPEN project.
Hans-Horst is the recipient of the CAPE-OPEN 2003 Award.
Hans-Horst is now retired and has no further activities in the field of process simulation and modelling. After his retirement he honored CO-LaN of his presence at the CAPE-OPEN 2006 Annual Meeting and at the CAPE-OPEN 2008 Annual Meeting.
