Highlights•Commercial power Backup system:

– Around 400 pcs. 2 kW systems (DIB 2000) shipped to date. – Fully commercial line production of fuel cell systems with our sister

company, Dantherm Air Handling. – Largest commercial project to date is the Danish Emergency Network

(Tetra) where 125 fuel cell systems are installed.

•Field test of Hydrocarbon systems:– Delivered 5 pcs. SOFC system running on natural gas. Next

generation SOFC system under development, expected deployment April 2010.

– 5 pcs. HT-PEM systems installed.

•Power Plant– 120 kW power plant for grid balancing delivered to BC Hydro. After 4

months of successfull testing at Powertech Labs the system in now being installed in Bella Coola - a small remote community north of Vancouver.

The integrated solution

Power Supply module with integrated UPS or power backup and reformer integrated when running on methanol

Hydrogen storage using compressed hydrogen in cylinders including hydrogen monitoring equipment

Optional climate control solution for cabinets and shelters

Production capabilities for volume

3,3 kW modules

Assembly line overview

Fuel Cell Modules, Sheet metal Boxes and Controllers

Cooling cost reduction: 5kWe site off-grid

Example:

Site with 3 kW DC-load.

2 kW AC-load for air-cons

DC BU

SOR

3 kW DC-load.

250 W DC-free cooling system

DC/AC inverter

Conclusion: Far simpler, cheaper and more reliable configuration with fewer batteries and far less fuel consumption during backup.

2 million hours with 100% availability

References – example 2

• 11 pcs 5kw systems deployed with Energi Midt fiber broadband installations in Denmark

• 100 % availability for a total of 340,000 hours since September 2007

• Backup system installed directly into rack space

• Perfect for both existing sites or newly deployed sites

• Interface towards base radios or independent system for alarms and monitoring

A 120 kW fuel cell power solution is a key part of BC Hydro's Hydrogen-Assisted Renewable Power (HARP) initiative

Will help reduce fuel consumption by increasing the utilization of existing renewable

power at BC Hydro's Clayton Falls hydroelectric generation plant in Bella Coola, BC.
