TOKYO GAS pilot project produces clean electricity from hydrogen and natural gas!

The Polymer Electrolyte Fuel Cell (PEFC) co-generation system is considered a promising technology to generate electricity and hot water with high efficiency and low environmental impact using natural gas.

A residential PEFC co-generation, which is connected to the utility grid, supplies electricity to a house and satisfies the hot water demand with recovered heat using a hot water storage tank. In order to achieve maximum energy saving, the residential PEFC co-generation is operated so as to just fulfil the hot water demand.

Hydrogen is the ideal fuel for fuel cell vehicles, which are emerging as the ultimate clean vehicle. Development of technologies related to producting pure hydrogen from natural gas is also being conducted.
