US Energy Initiatives Completes Development of Series 60 Detroit System for Solid Waste Authority of Ohio (SWACO); Hybrid Dual-Fuel Systems Technology

TAMPA, Fla.--May 18, 2006--USEIC/Hybrid Fuel Systems, Inc., ("Hybrid" or the "Company") (HYFS) manufacturer of a patent dual-fuel diesel to natural gas conversion technology, today announced the Company has completed development of one (1) 60 Series Detroit System for Solid Waste Authority of Central Ohio's (SWACO) 2005 Sterling truck.

The project included the development of a diesel/CNG duel fuel system for the Detroit 60 Series diesel engine with electronic injection. The engine is fitted in a truck/tractor and is used in bulk trash transferring in the Columbus, Ohio Region. This first truck will be evaluated for 3-6 months and a decision will be made regarding converting -- 25 additional trucks.

"We are pleased to have been selected by SWACO for this project," said US Energy CEO Mark Clancy. "The field testing we are about to begin will expose our system to the use of landfill gas and certain biofuels. We look forward to demonstrating the versatility of our technology while simultaneously showcasing the economic and environmental benefits of cleaner burning fuels," concluded Mr. Clancy.

Tim Berlekamp, Director of Planning and Business Development for SWACO, stated, "We believe in the use of landfill gas as a solution to regional mobile transportation." SWACO plans on showcasing the Sterling truck during a heavy-duty CNG applications and technologies seminar at Clean Fuels Ohio, May 23, 2006.

SWACO is the Solid Waste Authority of Central Ohio. They are one of the 52 solid waste districts created by the Ohio General Assembly in 1989. Each of those districts were established with the mission of reducing our reliance on landfills. Since birth, SWACO has become a catalyst for recycling and reuse programs in Franklin County and within their district. SWACO continues to pioneer with leading edge programs that find new uses for our "trash of the past, present and future."
