News Release: Quantum Awarded Contract for Hydrogen Refueling System

Quantum Fuel Systems Technologies Worldwide, Inc. (Nasdaq: QTWW), announced today it has received an order from a major European-based automaker for a transportable 10,000-psi (70 MPa) hydrogen refueling system. This refueling system will be used to refuel fuel cell vehicles operating with Quantum's 10,000-psi hydrogen fuel systems.

Quantum has developed and launched a line of stationary, portable, and mobile 5,000 and 10,000-psi hydrogen-refueling systems to support the emerging fuel cell market. Quantum's portable refueling units are designed to be user friendly based on simple and fully automated controls. They feature an interactive touch screen, one-button operation, automatic shut-off, and incorporate multiple redundant safety mechanisms and fueling controls compatible with California Fuel Cell Partnership or SAE protocols. The units are also designed with a defueling capability, which is an important feature that facilitates vehicle service operations. They operate on standard industrial power supplies and do not have special utility requirements.

Quantum's refuelers are certified for use as refueling appliances by Germany's regulatory agency, TUV (Technischer Uberwachungs Verein). Certification agencies and industry specifications require the units to safely manage pressure, temperature, and potential gas leakage issues with redundant safety features and thorough test and validation of components and systems.

'This contract expands Quantum's hydrogen refueling system products from our current 5,000-psi offering to 10,000-psi. The higher pressure storage systems developed by Quantum, which this new refueling system will now support, translate directly into a greater vehicle driving range for hydrogen fueled vehicles, a critical factor for the commercialization of fuel cell vehicles,'said Alan P. Niedzwiecki, President and CEO. 'Our refueling products are helping to provide the early underpinnings of the hydrogen refueling infrastructure market that is developing as we move toward a hydrogen economy.'

Quantum focuses on three primary product and system applications: Transportation, Stationary Power, and Refueling Infrastructure. The company manufactures both components and end products. In the Transportation sector, Quantum designs and supplies state-of-the-art fuel system technologies to many of the world's leading OEMs with Hydrogen systems for both Internal Combustion Engine (ICE) and Fuel Cell applications and Natural Gas and LPG fuel systems for internal combustion applications. For Stationary Power applications, Quantum currently supplies components and integrated systems to developers of fuel cell stationary power products and is working to expand its product portfolio in this area. In the area of refueling infrastructure, Quantum offers several hydrogen and natural gas refueling systems focused on early infrastructure development, targeting fleets of 1 to 20 vehicles.

Quantum's ultra-light weight composite fuel storage, fuel injection and metering technologies, electronic control products and OEM level systems integration capabilities have enabled the company to develop a product portfolio with state-of-the-art technologies and products, a diverse customer base, and strong alliances with partners such as General Motors and Sumitomo Corporation.

Quantum is a Tier 1 OEM supplier and a member of the GM Fuel Cell Alliance of fuel cell commercialization companies.
