Tech Brief: Renewable energy is essential to reducing the Military’s dependency on fossil fuels, particularly in the FOB. Introducing efficiently integrated renewable energy with grid and off-grid power-sources has its own set of challenges. ETI proposes a hybrid energy system integrating renewable energy with traditional sources in a modular, configurable system.


Value Proposition: As shown in the recent Iraq and Afghanistan engagements, off grid electrical power is essential to on-going operations. Most of this power has been produced by diesel/JP8 engine generators requiring numerous convoys and airlifts to deliver the fuel. This has resulted in high monetary costs as well as putting the convoy warfighters in jeopardy to roadside IEDs. In discussions with military personnel regarding these issues, ETI has been exploring the use of fuel cells to displace the engine generators. Overall fuel cell power is more efficient compared to engine generators. One method is to use the same JP8 fuel as feedstock to a reformer to produce hydrogen for the fuel cell. Consequently, we developed a rugged fuel cell generator and in collaboration with the Battelle Institute, we developed a JP8 reformer front end. This solution may use less JP8, but it still requires some convoys. Therefore, we continued to explore ways of producing hydrogen from locally available feedstocks, preferably renewable feedstocks such as ethanol, methanol, methane, cellulose, wood, grass, corn, municipal solid waste, and other organic or hydrocarbon materials local to the region. The result of this endeavor is the ETI Bio-Reformation process discussed in this document.
