Net~Gen

With customer feedback indicating the need for smaller, simpler SOFC powered micro-CHP systems - CFCL focussed considerable engineering efforts on designing Net~Gen. Many of the additional features of which are commonly available with boiler systems were removed from CHP2. This allowed a significant reduction in size of the unit, which is critical for replacing existing boilers while also enabling the Net~Gen unit to be mounted in a variety of indoor locations.

The focus of Net~Gen is not a finished appliance, but a pre-commercial demonstration unit, allowing potential appliance companies and utilities to see that SOFC powered micro-CHP systems are ready for commercialisation. These field trials allow utilities to further explore the potential of clean efficient electricity generation from sophisticated micro-CHP units, such as Net~Gen.

CFCL is producing limited quantities of Net~Gen units for collaboration with selected utilities and appliance manufacturers in order to integrate the SOFC technology into household appliances. for the future.

Design Highlights

Substantial reduction in the number of components
Further simplification of control systems and individual components
The unit is an ‘all in one' system with simple connections to services
Utilisation of a balanced flue - allowing the unit to be mounted in confined locations (example basements)

Engineering Achievements

System designed & built within four months.
Internal water treatment plant and gas desulphuriser
Size of the unit was reduced significantly - 56% smaller than CHP2
Improved electrical system designed to provide maximum protection of the fuel cell stack
Simplified gas train using commercially available components
Small heat exchanger and very tight integration of all components
Reduced parasitics - which in turn increase the amount of exported electricity
European CE approval
