History and Plan of ENE-FARM Commercialization in Japan
After technology verification and large scale monitoring program, Japan started
initial commercialization of 1kW class residential PEMFC “ENE-FARM” in
FY2009. Around 50,000units are now operated in Japanese household.

Large Scale Monitoring Program by Japanese Government
Five system manufacturers joined
to the program, and delivered
3,307units.
Toshiba delivered 748 units among
them.
The Amount of CO2 Reduction [kg/month]
In advance of commercialization, over 3,300unit of residential PEFC were
installed and verified in FY2005 through 2008 under governmental program. In
the program, system showed enough performance and reliability as future
commercial product.
Thermal Load of each House [MJ/month]
Residential PEFC showed the
performance to reduce 100kg/month
of CO2 as the average.
