Ultra-USSI
P250i Fuel Cells

Ultra-USSI's P250i Solid Oxide Fuel Cells provide a reliable source of DC power by converting chemical energy into electricity. Powered by propane or natural gas, the P250i is capable of providing days, weeks and even months of reliable, clean, extended-run backup power protection for a variety of critical infrastructure needs. 

How It Works?

The P250i is designed to work with existing power infrastructure.  Powered by readily available and low cost propane or natural gas, the P250i has the ability to sit in standby mode for months to years at a time monitoring battery voltage.  The P250i will automatically start once the batteries dip below a pre-determined lower threshold voltage.  After a 25-30 minute startup period, the P250i will begin charging the batteries and powering the load.  Once the batteries reach a pre-determined upper threshold voltage, the P250i will automatically begin to cool-down and return to standby mode.

Features & Benefits:

The Ultra-USSI P250i Solid Oxide Fuel Cell has several advantages over other backup power solutions like gas/diesel gensets. 

Propane or Natural Gas

P250i Propane

The P250i is powered by readily available and low cost propane or natural gas.  During operation the P250i efficiently burns 1/4lb LP/hour and can provide 130-160 hours of run-time on two (2) BBQ style propane tanks. 


Easy Integration

P250i Integration

The P250i integrates seamlessly with the utility grid, generators, batteries, solar & wind, solar charge controllers, DC-DC converters, fused external communications, computers, modems and other customer electronics.


Zero Maintenance

Zero Maintenance

The P250i needs no oil changes, has no moving parts and requires no routine maintenance.  In fact, the P250i can sit in standby mode for months to years at a time monitoring battery voltage and only run when its called upon.


Telematics Monitoring

Telematics

Telematics (optional pkg) provides real-time and historical operational visibility via cellular/satellite service to web portal dashboard with data logging, status reports, 2-way communications and much more to reduce site trips and increase system uptime. 


All-Weather Performance

All-Weather Performance

The P250i utilizes a ceramic electrolyte which is not susceptible to freezing and thawing cycles common among other fuel cell types.  Its robust design allows the P250i to reliably operate in virtually any climate -40°F to 122°F. 


Proven Deployment

Fuel Cell Photos

Over the past 2-3 years we've deployed several hundred P250i's for various critical infrastructure applications.  Check out a handful of installations in our Photo Gallery.


Applications:

An extended power outage from an ice storm, wind storm, hurricane or other phenomena doesn't have to paralyze your operation.  While battery back-up can provide hours of protection, extended up-time isn't ensured unless your equipment is proactively backed-up with Ultra-USSI's P250i Solid Oxide Fuel Cells. 

Railroads

Railroads

The P250i is capable of providing days, weeks and even months of extended-run backup power to charge battery banks and power loads at highway crossings, intermediate signals and other equipment along the wayside, ensuring that critical equipment and trains remain operational.  


Oil & Gas

Oil & Gas

The P250i is capable of providing days, weeks and even months of extended-run backup power to charge batteries and power loads at upstream, midstream and downsteam SCADA equipment, remote telemetry & monitoring (RTU), gathering measurement and controls and much more! 


Infrastructure

Infrastructure

The P250i is capable of providing days, weeks and even months of extended-run backup power to charge batteries and power loads at critical traffic intersections, security & surveillance systems, advanced warning systems, weather stations, remote monitoring and much more!
