Tokyo Gas is conducting R&D on natural gas fuelled PEFC co-gen aiming the commercialization especially for residential application. As part of the activity towards the market introduction of a residential PEFC co-gen in early 2005, the field test of PEFC co-gen at actual house has been carried out from March, 2002. To achieve the high energy saving and reduction of Coa emission by introducing a residential PEFC co-gen, not only the performance but also the operation control method of the PEFC co-gen is important. To maximize the running merit of the PEFC co-gen, development of an operation control system that minimizes the reverse power to the utility grid and avoids the surplus of hot water with minimized start-up and shutdown times has been conducted. Concluding those, the results of the field trials such as energy saving will be reported at this time.
