General Motors Co, en forma conjunta con el TARDEC (<\/span>Army\u2019s Tank Automotive Research Development and Engineering Center),\u00a0<\/span>ha desarrollado un veh\u00edculo \u00a0propulsado por un motor el\u00e9ctrico, sobre la base de Celdas de Hidr\u00f3geno, del tipo FCEV (Fuel Cell Electric Veh\u00edcle), con el objetivo de disponer de un medio de transporte especialmente apto para \u00a0misiones de infiltraci\u00f3n de FFEE.\u00a0 El CHEVROLET COLORADO ZH2, dispone de un motor que no solamente es mas silencioso que los motores <\/span>de combusti\u00f3n interna\u00a0convencionales, \u00a0sino que adem\u00e1s funciona en un rango de temperaturas entre los 60\/80\u00aa C, lo que reduce la “firma t\u00e9rmica” del mismo. Este motor puede entregar una potencia continua de 25Kw, con picos de 50 Kw, y su consumo es de unos 7.5lts\/hora.<\/span><\/p>\n

\"TheImagine you\u2019re a <\/strong>U.S.<\/span> Special Forces operator on a dangerous mission. You need to hit a terrorist\u2019s mountainside compound without the host country knowing that you\u2019re there, so you need a ride that\u2019s quiet and carries a low thermal signature. General Motors has a truck that they want to put you\u00a0in.<\/p>\n

The Chevrolet Colorado ZH2<\/span> is an electric truck powered by a hydrogen fuel cell that runs far quieter and cooler (between 60 to 80 degrees Celsius) than conventional automobiles. It\u2019s almost a forward operating base unto itself, capable of producing 25 kilowatts of continuous power (and up to 50 kilowatts at peak output), along with two gallons of water per hour. The vehicle itself is a modified Chevy Colorado, rigged for off-road performance with bigger tires, better suspension, longer wheelbase,\u00a0etc.<\/p>\n

Unveiled Monday at the Association of the U.S.<\/span> Army conference in Washington, D.C., the ZH2<\/span> is a technology demonstrator, so it\u2019s not going to hit the battlefield\u00a0yet.<\/p>\n

The truck was developed in partnership with the Army\u2019s Tank Automotive Research Development and Engineering Center, or TARDEC<\/span>, which entered a unique research collaboration with GM<\/span> to make sure the ZH2<\/span> could meet military requirements. TARDEC<\/span> entered into a contract with GM<\/span> a year ago to produce the\u00a0demonstrator.<\/p>\n

A year from contract to car is incredibly fast for the auto industry, much less for the military. But the relationship was almost four years in the making. It began when GM<\/span> and TARDEC<\/span> began working together Michigan in fuel cell research facilities that were about 20 minutes apart<\/a>. They \u201cprovided some of their test facilities to us and integrated them into our laboratories,\u201d said Rogers. TARDEC<\/span> engineers tested the GM<\/span> fuel cell stacks for performance, endurance, etc. \u201cWe are gaining access to several billion dollars of technology investment from General motors. They are gaining the value of a second party gaining evaluating and measuring data on their\u00a0systems.\u201d<\/p>\n<\/div>\n

In January, the Army will take possession of the vehicle and give it to soldiers to go mudding\u2026er, put it through rigorous off-road testing, at Fort Bragg, Fort Benning, and Quantico, as well as some technical testing in Michigan. The Special Operations community will help test the vehicle, whose stealth features would be most appropriate for SOF<\/span> missions, said TARDEC<\/span> director Paul\u00a0Rogers.<\/p>\n

\u201cThe ability to position yourself at a point of advantage on the battlefield, without exposing yourself, SOF<\/span> definitely,\u201d Rogers said at a preview event for the vehicle on Sunday night. \u201cThere are other reconnaissance, surveillance, target acquisition\u00a0roles.\u201d<\/p>\n

The ZH2<\/span> \u201cis not a combat vehicle\u201d said Christopher Colquitt, a senior project engineer at GM<\/span> who led the project. It isn\u2019t armored and wouldn\u2019t stand up well against an IED<\/span>. \u201cAll those things would have to be considered for a combat-ready\u00a0vehicle.\u201d<\/p>\n

GM<\/span> and Army officials are optimistic that the hydrogen fuel cell system will have applications beyond a single demonstrator. But anyone who remembers learning about the Hindenburg disaster might have a few reservations about running vehicles on hydrogen<\/a>, including cars.<\/a><\/p>\n

Colquitt acknowledged the Hindenburg connection. \u201cHydrogen is a fuel, yes. Does it have flammable properties in certain conditions? Yes. But pure hydrogen isn\u2019t flammable. You have to mix it with air and have an ignition\u00a0source.\u201d<\/p>\n

The truck has three tanks of compressed hydrogen in the back of the vehicle, he said. Those tanks are composed of an inch of carbon fiber to keep the hydrogen away from fire and\u00a0air.<\/p>\n

Rogers didn\u2019t seem concerned about the hydrogen issue, calling it an \u201cadditional area that we want to explore to make sure that there are no secondary effects for the types of threats that we deal\u00a0with.\u201d<\/p>\n
