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

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. —Curran et al.

Kentucky electric cars now pay two taxes where gas cars only pay one

Baua Electric

Photo by Mobilus in Mobili on Flickr As of January 1st, Kentucky has implemented not one but two new taxes on electric vehicles, both of which are individually higher than what gas vehicles pay on similar units of energy. cents, compared to a current average gas price of $2.78 per gallon in the state).

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

This year’s outlook is the first to highlight the significant impact that falling battery costs will have on the electricity mix over the coming decades. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear. Coal emerges as the biggest loser in the long run.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

Scenario study suggests increased vehicle electrification in Europe increases demand for gas in power sector; limited ability for power-to-gas

Green Car Congress

A study published by the Centre on Regulation in Europe (CERRE) has explored the possible impact of increased electrification of road transportation and domestic heating and cooking on the energy system (electricity and gas), as well as on CO 2 emissions and on GDP.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The Stanford study considered a future US grid where up to 80% of the electricity comes from renewables. Click to enlarge. A new study by Charles J.
