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

Green Car Congress

WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains.

U. Mich study: natural-gas-based ICE, BEV and FCV all show promise for environmental benefits relative to conventional ICE

Green Car Congress

Qiang Dai and Christian Lastoskie found that BEVs and FCVs in particular offer significant reductions in greenhouse gas emissions, especially if carbon capture and sequestration (CCS) technologies are implemented at the fuel conversion facilities. Their study appears in the ACS journal Energy & Fuels. … —Dai and Lastoskie.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Methanol-powered vehicles are one pillar of Geely Auto’s diversified new-energy strategy, which also encompasses ethanol, CNG, gasoline-electric hybrid, plug-in hybrid, pure-electric, and extended-range solutions. Click to enlarge. Currently the company has a 4,000 metric ton/year production capacity.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Because the use of natural gas for transportation requires compressing, liquefying, or conversion, it is important to determine the best use of natural gas as a transportation fuel. —Curran et al. L/100 km).

New petroleum refining lifecycle model finds the variability in GHG emissions from refining different crudes as significant as magnitude expected in upstream operations

Green Car Congress

Comparison of GHGenius, JACOBS, TIAX, and the new PRELIM gasoline greenhouse gas (GHG) estimates using base case estimates and variations from the scenario analysis. Annual GHG emissions from a large refinery are comparable to the emissions of a typical 500 MW coal-fired power plant. electricity contributes 10?21%.

Naysayer Alert – the hydrogen red herring

My Electric Car

Proponents believe such a car could be easily refuelled with hydrogen and assumed it would have greater range than a pure all-electric car. Little seems developed in any wide commercial sense and certainly not to the extent of the pure electric car. It is important to realize that a fuel cell car is actually an electric car.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

This is particularly true in the electric power sector, where, in the US, natural gas sets the cost benchmark against which other clean power sources must compete to remove the marginal ton of CO 2. Natural gas use in the transportation sector is likely to increase, with the primary benefit being reduced oil dependence.
