NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

A new study by a team at the National Renewable Energy Laboratory (NREL) concludes that a high-pressure, scalable, intra-city hydrogen pipeline system could improve the economics and logistics of hydrogen delivery, making it potentially cost-competitive with gasoline. The smallest modeled system connects eight existing stations.

Audi using supplementary port fuel injection to address particulates from gasoline direct injection

Green Car Congress

In part-load operation, the indirect injection supplements direct gasoline injection to improve fuel economy and to reduce the output of particulates from the engine. Port Fuel Injection (PFI) engines, on the other hand, have no trouble in meeting the limits, although the number of particles emitted varies with driving behavior.

FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

Harris AutoTECHCAST Study Finds US Vehicle Owners Currently Would Choose Lower-cost, Higher Fuel Economy Gasoline-Engined Vehicles Over Higher-Priced Alt Fuel Engines or Electric Vehicles

Green Car Congress

According to Harris Interactive’s 2010 AutoTECHCAST study, conducted between 6-26 April 2010, there is currently greater demand among US vehicle owners for technologies that deliver improved fuel economy of existing gasoline-driven engines at a lower initial cost, rather than for higher-priced alternative-fueled engines.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). This growth arises from increases in air transportation outpacing increases in aircraft fuel efficiency.
