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

Green Car Congress

Hydrogen production pathways include low- and high-temperature electrolysis; solar thermochemical disassociation; photobiological splitting (four pathways: direct and indirect biophotolysis using hydrogenase and nitrogenase); gasification (coal, biomass); steam reforming (methane, ethanol); and partial oxidation.

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. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide. Process flow diagram. Source: SRI.

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

Primary energy sources in model include fossil fuels (crude oil, natural gas, and coal); non-renewable non-fossil sources (nuclear); and renewable sources (hydroelectric, wind, solar, and biomass). These energy sources can be converted to transportation fuels or used for generation of heat, electricity, or both (cogeneration).

RAND study concludes use of alternative fuels by US military would convey no direct military benefit; recommends energy efficiency instead

Green Car Congress

If the US military increases its use of alternative jet and naval fuels that can be produced from coal or various renewable resources, including seed oils, waste oils and algae, there will be no direct benefit to the nation’s armed forces, according to a new RAND Corporation study.

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.

Report from the REFF-Wall Street; Themes in Renewable Energy Finance

Green Car Congress

Biofuel projects are going to have trouble getting financing from Wall Street this year because all of them have questions about the long term pricing of petroleum; most of them have concerns about the pricing stability of their feedstocks; and many of the cellulosic projects have concerns about the conversion technologies.
