Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains. Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. Lifecycle GHG comparison. The cost per gallon for the SRI fuel is higher than F-T fuel, however: a calculated $2.81 Click to enlarge.

The Case for Nuclear Cargo Ships

Cars That Think

The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore.

FT and FT blends significantly reduce gaseous and particulate emissions compared to conventional JP-8 fuel in helicopter engine

Green Car Congress

The goal of their study was to understand how alternative fuels affect the primary PM emissions, the semi-volatile nature of the these emissions, and the potential for the emissions to form secondary PM. particle conversion at the high concentrations present in many source tests but exist as vapors in the ambient atmosphere.

Naysayer Alert – the hydrogen red herring

My Electric Car

The energy stored within hydrogen has been imparted from electrical energy through the electrolytic hydrogen production process or more likely in the refinement of fossil fuels such as coal seam (methane) gas – both are energy intensive processes in themselves. . The reasons are numerous. .

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. Conclusions. slow charge.
