PRODUCTION RISK IS NEGLECTABLEThe ReGen process is in fact a 3 stage production , going from decontimation ( CSU module ) to solvent extraction ( MSU module ) ending wih hydro treatment ( MTU module ).
The process in combining these 3 modules under specific circumstances is new ( and patented by GIII ). But the different modules separately have been running in a great number of installations and on a commercial scale. So there is no doubt about their performances and the underlying tecnhology.
In addition the ReGen process has also been thoroughly tested on vendor scale basis.
So the conclusion should be simple , the production risk is neglectable. BP has performed due diligence during 18 months on the company including the technology. If there would have been any doubt on the technology and the ability to bring the technology in production, they would never have signed a definitive offtake agreement.
