Abstract:The fast development of renewable energy sources such as wind and solar in generating electricity has affected the electricity market, especially on shifting the price. This condition risks Twence B.V. in facing future energy market. On the other hand, Twence B.V. emits abundant amount of CO2 that is valuable as a carbon source making sustainable product. Carbon Capture and Utilisation (CCU) and Power-to-X (PtX) concepts are promising for Twence B.V. forthcoming activities. This study evaluated the possibility of realizing CCU-PtX technology at Twence B.V. Several routes were identified and investigated. Preliminary selection was conducted through weighting score method. Further justification was conducted by simulation using ASPEN HYSYS v.8.8 and business case analysis. Brief overview on scaling possibilities and potential risk and opportunities identification were also presented. In a nutshell, at the reserved assumptions and limitations, the study concludes that the most attractive CCU-PtX alternative in Twence B.V. is formic acid production with CO2 uptake of 15 ktons/year to produce 18 ktons/year of formic acid. This alternative needs investment of € 43 million and possibly has internal rate of return of 13.3% corresponds to net present value of € 13 million.
