46 HDT • SEPTEMBER 2014 www.truckinginfo.com FuelSmarts FUEL in the News Green FleeT conFerence nexT monTh T his year's Green Fleet Conference will include a series of sessions aimed specifically at trucking fleets called the Heavy Duty Green Symposium. The conference will be in Schaumburg, Ill., from Oct. 29-30. Four sessions make up the HD Green Symposium: • Natural Gas: Things We Should Have Known Before • 121 Ways To Save Money On Fuel • Looking Ahead: Emerging & Future Alternative Fuels & Powertrains • What You Can Learn From the EPA's Super Truck Program Find out more at www.greenfleetconference.com. naTural Gas boominG in Texas T he use of natural-gas- fueled vehicles is grow- ing in Texas, which holds a quarter of the nation's natural gas reserves. CNG and LNG sales in Texas through July 31 were 220% of the fiscal year 2014 estimate — an estimated 14.5 million gallon-equivalents, compared to the forecasted 6.6 million. One key area natural gas fueling suppliers are concentrating on is the "Texas Triangle," with the goal of allowing natural-gas travel between Hous- ton, Dallas and San Antonio. Clean Energy opened a San Antonio station that offers both compressed natural gas and liquefied natural gas for this critical goods movement cor- ridor this year. In addition, Love's opened its first fast-fill CNG station in the Texas Triangle, in Willis. recapTurinG lnG boil-oFF B lu says it's developed a way to prevent the venting of liquefied natural gas into the atmosphere. A new gas recapture system at its LNG fueling station in Nampa, Idaho, captures boil-off gas from the LNG storage tank. It warms it to return it to gas form, then sells it back to the natural gas company, putting it back into the pipeline. The Global alT-Fuel ouTlook A report from Navigant Research projects that worldwide sales of alter- native fuel vehicles will reach 14% of total sales of medium- and heavy- duty vehicles by 2035. The total number of medium- and heavy-duty vehicles in use worldwide will nearly double between 2014 and 2035, according to the report. The percentage powered by diesel is expected to fall from more than 79% in 2014 to 76% in 2035. the project. Siemens is also supply- ing current collectors, the technolo- gy that allows trucks to connect and disconnect from the catenary sys- tem at any speed, to local California truck integrators whose vehicles will also be part of the demonstration. With the use of a current collector, the trucks can connect and discon- nect from the catenary system at any speed for dynamic power supply directly to the electric engine and for on-board storage. To ensure the same flexibility as conventional trucks, the "e-highway" vehicles can use a hybrid electric drive system, powered by diesel, compressed natural gas, battery or another on- board energy source, when driving outside of the catenary lines. The management district had commissioned a report by an inde- pendent consultant that investigated how air quality can be improved, despite increases in drayage traffic between the ports and inland logis- tic hubs. It concluded that catenary hybrid vehicles "can simultane- ously address emissions and fuel economy issues while providing operational flexibility at a similar or lower cost of ownership as other zero-emission technologies." The demonstration project serves the purpose of evaluating the tech- nology. It is the intention of this dem- onstration to generate a knowledge base for a potential future extension of the system to commercial applica- tions locally and regionally, accord- ing to Siemens. The project installation will begin immediately with infrastructure commissioned and first truck inte- grated in order to start the one-year demonstration in July 2015.
