The small SES is a configurable water electrolysis infrastructure solution that produces and delivers up to 3 Nm3h (114 scfh or approximately 6 kg a day) of clean, pure hydrogen that can be used in industrial, power and transportation applications.
"We developed this next generation product to meet the growing demand for a reliable, economic supply of hydrogen in smaller quantities, " said Jon Slangerup, President and CEO of Stuart Energy. "I am particularly excited about the transportation market for these SES systems. We believe this product is perfectly suited for emerging 'hydrogen highway' projects that are aiming to put hydrogen fueling infrastructure in place as vehicles are introduced.
Because our SES product portfolio can be scaled from small to very large applications, we are able to offer hydrogen infrastructure solutions that can keep pace with the growth of hydrogen-powered vehicles and power applications over time."
The SES product line is a modular system that consists of Hydrogen Generation, Compression, Storage, Power and Fuel Dispenser modules. The small SES is designed to safely and reliably generate up to 3Nm3h (114 scfh) of hydrogen, at up to 99.9995% purity, depending on the purity package selected. Based on the Company's proprietary Vandenborre IMET(R) cell stack, the small SES uses electricity to efficiently separate water into hydrogen and oxygen. The hydrogen is produced at 25 bar (363 psi). Pressure can be boosted to 417 bar (6000 psi) by ussing an optional Compression Module.
By configuring the SES modules, a customer can build a system suitable for industrial and energy applications where a small quantity of hydrogen is required. These applications include laboratory fuel cell testing, generator cooling in thermal power plants, vehicle fueling, battery replacement, small off-grid power, and a variety of other infrastructure applications.
When tied to renewable sources of electricity, such as PV solar or wind power systems, the SES offers a completely zero-emission energy cycle.
The small SES unveiled at Governor Schwarzenegger's announcement is configured to operate directly from PV solar power, or from grid electricity, depending upon the customer's application. This small SES is being demonstrated using Solar Integrated Technologies' unique solar canopy, which produces sufficient off-grid electricity to fully operate the small SES. This product demonstration shows one of several possible consumer applications for on-site hydrogen generation, storage, fueling and distributed power.
The Company is also using the small SES platform in the development of its HomeFueler(R), which is being designed to allow hydrogen vehicle owners to fuel their car in the comfort and convenience of their own home.
