FORT LAUDERDALE, FL - October 3, 2007 - Ener1, Inc. (OTCBB: ENEI) today announced that its EnerFuel subsidiary will exhibit EnerOptix, a new fuel-cell-powered remote surveillance camera, at the 2007 Fuel Cell Seminar and Exposition in San Antonio Texas October 15-19, 2007. A limited number of the recently completed beta version of the product will be available for sale in late October.

The four-camera system streams digital photos to a secure online web server, allowing consumers to view remote locations continuously. The camera can operate from 90-180 days depending on the number of photos taken per hour. The variety of uses include monitoring vacation homes during the off-season, observing a hunting blind from the cabin or taking continuous nature photos while hiking. In order to provide the continuous power, EnerFuel developed a unique method of extracting hydrogen from a chemical hydride.

Rex Hodge, President of EnerFuel, stated, "While fuel cell powered automobiles and stationary power are part of our energy future, we believe there is a market and technology today for portable-fuel-cell-powered consumer products. Our proprietary method of creating remote energy can be applied to many consumer products with low power requirements."

Charles Gassenheimer, Vice Chairman of Ener1, commented, "We congratulate the EnerFuel team members who tirelessly developed this product in record time. We established a number of milestones in June 2007, and our employees continue to deliver to our shareholders on those promises."
