Fort Lauderdale, FL - October 4, 2005 - Ener1, Inc. (OTCBB: ENEI) announced today that Ulrik Grape has joined its EnerDel battery subsidiary as its Chief Executive Officer.

EnerDel expects to immediately benefit from Mr. Grape's more than 18 years of relevant experience in senior management, business development, manufacturing and finance. Previously, Mr. Grape spent ten years with Danionics A/S, an international lithium battery company headquartered in Denmark, where he was Sales and Marketing Director and Vice President U.S. At Danionics, he successfully secured major contracts for its lithium-ion polymer rechargeable battery product line and developed strong customer relationships with leading U.S. portable electronic product manufacturers.

Kevin Fitzgerald, Chief Executive Officer of Ener1, commented, "Ulrik's appointment as EnerDel's CEO is excellent timing for us on two critical counts. First, we believe that his track record in the lithium-ion battery industry will provide EnerDel with invaluable competitive advantages that will enable EnerDel to take the lead in technology and marketing for supplying the U.S. hybrid electric vehicle (HEV) industry with next-generation battery power sources. We are convinced that the success Ulrik demonstrated in his previous battery industry posts will give EnerDel a clear insight and advantage in serving the needs of the U.S. HEV marketplace. Secondly, Ulrik's prior experience as a key member of a management team that successfully conducted an initial public offering will be invaluable to EnerDel." On September 6, 2005, Ener1 announced its proposed plan to spin-off the common stock of EnerDel and the other operating subsidiaries in its alternative energy business divisions, eventually making them stand-alone companies, the spin-offs being subject to Ener1's ability to obtain any necessary regulatory approvals and raise capital to fund the operations of the new public companies.

Mr. Grape added, "I am gratified by the confidence Ener1 and its board of directors has placed in my abilities to lead and position EnerDel in the marketplace. We are now at a critical juncture in the history of EnerDel's lithium-ion battery technology, manufacturing processes, and market penetration. I believe that we are poised for tremendous growth. I look forward to assembling a world-class management team that will get the job done, taking EnerDel to the next level within the lithium-ion battery industry."

Grape has also held senior executive positions in other competitive, international industries, including the airline and construction equipment industries. These include positions as Managing Director for Volund A/S, a privately held Danish industrial group manufacturing mobile access platforms and other structures and Associate at Trap & Kornum A/S, a mergers and acquisition firm operating in the Scandinavian market. Mr. Grape earned a Bachelor's degree in International Politics and Affairs from Georgetown University and a Masters of Business Administration degree from French business school INSEAD.
