POSSIBILITY OF ACTIVE CARBON RECYCLE ENERGY SYSTEM processes than electricity and heat of primary energies. ACRES has potential in those industries. ACRES still requires technologies for CO 2 recovery and hydrocarbon regeneration. Development of a practical process using ACRES and the optimisation of the process will be required in the next study. Conclusions For an establishment of a practical ACRES, selections of recycling hydrocarbon media and primary energy source for the system drive were important. Methane was the easiest material for regeneration and cyclic use. Methanol or ethanol with ACRES was suitable for vehicle use. CO was the most suitable for a recycle media in ACRES, because CO had higher energy density and affinity than H 2 to chemical processes in conventional manufacturing industries. HTGR was a candidate of primary energy source of ACRES. ACRES with CO driven by heat output from HTGR was the most applicable combination. ACRES was expected to have higher efficiency than H 2 energy system and be a candidate of energy systems for establishment of carbon supply security in a modern society.
