ISE Limited's Fuel Cell Hybrid Drive System Provides Riders with Safe, Reliable, Zero-Emission Mass Transit at the 2010 Winter Games

The ISE Limited hybrid drive system powers BC Transit's entire fleet of 20 fuel cell hybrid buses and this fleet constitutes the world's largest zero-emission bus fleet in operation today.

SAN DIEGO " (February 24, 2010) " Bus travelers in Vancouver, British Columbia, Canada, are riding greener because of 20 zero-emission, fuel cell hybrid buses produced by California-based ISE Limited (TSX: ISE). ISE's hybrid drive system technology is helping BC Transit progress into a low carbon future.

Rick Sander, CEO and President of ISE, said "This is an exciting opportunity for visitors from all over the world to see the commercial strength and viability of these hybrid buses. This represents another milestone for ISE as a global leader in zero-emission hybrid technologies for a cleaner world." The BC Transit fleet is comprised of 20 hybrid buses that use ISE's core technologies in the complete hybrid propulsion system: energy storage, controls software and power electronics. The hybrid buses also use Ballard fuel cells and New Flyer chassis.



ISE Limited Conducted Rigorous Performance Tests

Since ISE was first selected to provide the drive systems inside these state-of-the-art vehicles, ISE has conducted hundreds of complex and rigorous performance tests over more than 12 months to ensure their safety, reliability, and performance in extreme conditions.

To assess operational performance ratings in freezing weather and on tough terrains, cold chamber testing was conducted on each hybrid fuel cell vehicle. The low temperature assessments test safety as well as optimal functionality in temperatures as low as -20C. These tests provide real-world data regarding operation and reliability of the hybrid fuel cell vehicles in environments that simulate the coldest winter temperatures in Vancouver.

Road testing was conducted over tens of thousands of accrued miles/kilometres, generating critical durability, reliability, and operational performance data. A significant amount of this performance data was collected via ISE's proprietary Remote Diagnostic Unit (RDU).

Alex Bernasconi, Sr. Vice President, Sales and Marketing, said "It is especially important to ISE that we ensure a smooth operation of the hybrid buses because we know the hybrid buses are one of the green highlights of the 2010 Winter Games. The exhaustive testing that we conducted prior to the delivery of the fleet was essential to ensuring safety and reliability. Our service team is currently in British Columbia during the games, as part of our commitment to BC Transit."

Tavin Tyler, Director of Fuel Cell Bus Programs, said "Because our drive system does not burn fossil fuel, there is a nearly non-existent environmental impact. This translates into increased safety and lower maintenance costs." The ISE fuel cell hybrid system powering these buses converts the chemical energy of hydrogen to mechanical energy. The combination of hydrogen and oxygen in the fuel cell powers the electric drive system without any carbon exhaust.

After the conclusion of the 2010 Winter Games in Vancouver, the fuel cell hybrid buses will remain in service throughout specified routes determined by BC Transit. Local riders will benefit from smoother and quieter commutes as a result of ISE's fuel cell hybrid technology powering each bus. Because hydrogen fuel only emits water vapour, there is no exhaust odour of Nitrogen Oxides, black tailpipe soot (particulate matter), or polluting carbon dioxides.
