The North African sale, to a major international generator manufacturer, is for a complete hydrogen supply and storage system to "cool" the electricity generators that will be installed at a new power plant now under construction. The installation will include two HOGEN® H-Series hydrogen generating units and gas compression and storage systems, to be delivered in the fourth quarter of 2007. The company said the order reflects growing demand for its products in the global generator cooling market.

The Florida project involved successfully installing and commissioning an on-site hydrogen vehicle fueling system at a service station in Orlando. The station showcases the company's proton exchange membrane electrolysis (PEM) technology, which uses electrical energy to convert water into hydrogen fuel that can be safely stored at the station, and dispensed into clean and efficient hydrogen-fueled automobiles. The Orlando station is one of 14 such hydrogen fueling locations Distributed Energy Systems has helped develop since 2002.
