Clean Cities Annual Metrics Report 2006
7/1/2007
Clean Cities coordinators submit an annual report of their activities and accomplishments for the previous calendar year. Coordinators submit a range of data that characterize the membership, funding, projects, and activities of their coalitions as well as data about sales of alternative fuel blends, deployment of alternative fuel vehicles, hybrid electric vehicles, idle reduction initiatives, and fuel economy activities. NREL analyzes the data and translates them into gasoline reduction impacts.
Survey results indicate that about 375 million gallons of gasoline were displaced through Clean Citiew efforts in 2006, 50 percent more than in 2005. Alternative fuel vehicles accounted for 71 percent of the reduction. Biofuels (ethanol and biodiesel) used in AFVs displaced 128 million gallons, 34 percent of the total 375 million.

US10 Capable Prototype Volvo MG11 Natural Gas Engine Development: Final Report
10/1/2006
This project was designed to develop a low emissions natural gas engine. The emission targets for this project were 0.27 g/kW-hr (0.2 g/bhp-hr) of NOx and 0.013 g/kW-hr (0.01 g/bhp-hr) of particulate matter. To meet the objective, a chemically correct (stoichiometric) combustion, natural gas engine with exhaust gas recirculation (EGR) and a three-way catalyst was development. In addition to low emissions, diesel-like efficiencies were targeted trough the use of a Sturman camless Hydraulic Actuated Valve (HVA) system.

Credit for New Qualified Alternative Motor Vehicles (Advanced Lean Burn Technology Motor Vehicles and Qualified Hybrid Motor Vehicles)
1/13/2006
On January 13, 2006, the Internal Revenue Service (IRS) issued guidance regarding the tax credits for light-duty (less than 8,500 lbs. GVWR) lean-burn and hybrid electric vehicles. The guidance establishes the procedures that manufacturers must use to certify that their vehicles qualify for the tax credit. The IRS plans to issue additional guidance at a later date to address procedures for qualifying alternative fuel vehicles, fuel cell vehicles, and heavy-duty hybrid vehicles.
The guidance provides procedures whereby a manufacturer may certify to the IRS that its vehicles qualify for the tax credits enacted in EPAct 2005. The guidance also provides procedures for reporting on the total number of qualifying vehicles that have been sold. Upon receiving the required information, the IRS will issue an acknowledgement. A manufacturer that has submitted the proper certification and received an acknowledgement from the IRS may then certify to customers/puchasers that the vehicles qualify for tax credits. For taxpayers to claim the credit, they must place the vehicle in service after December 31, 2005. The taxpayer also must be the original user of the vehicle (first purchaser or lessee) and the vehicle must be predominately used in the U.S.

9/1/2005
NREL and the South Coast Air Quality Management District (AQMD) through separate agreements are funding a program with Mack Trucks Inc. to develop the next generation heavy-duty natural gas engine to be installed in a refuse hauler. Mack and Southwest Research Institute developed the E7G 12-liter lean burn natural gas engine to operate with stoichiometric (chemically correct) combustion and cooled exhaust gas recirculation (EGR). This engine was coupled to a three-way catalyst for reducing emissions. The objective of the project is to develop a natural gas engine with nitrogen oxide (NOx) and particulate matter (PM) emissions of 0.5 g/bhp-hr and 0.01 g/bhp-hr respectively with the use of a three-way catalyst.
