-- Demonstration of hydrogen generation from sewage biogas source Demonstration of hydrogen generation from sewage biogas source ––

1. Background of the demonstration1) The digestion gas is used for the gas generation and the warming of digestion tank,1) The digestion gas is used for the gas generation and the warming of digestion tank,

but approximately 30% are not used effectively.2) Hydrogen production from biogas is CO2 free.3) Biogas is the energy of local production for local consumption.4) Th d i f h h d i i bi i h fi i i J

2. The demonstration plant

4) The demonstration of the hydrogen station using biogas is the first time in Japan.

① Construction costs 1,378 Million Yen

② Maintenance costs 66.5 Million Yen/Year

2. The demonstration plantLocation
