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. Their open access paper is published in the journal Energy.

The Net-Zero Neighborhood: Advanced Energy Storage and Highly Efficient Photovoltaics Take Transportation Off the Gasoline Grid and Residential Off the Electric Grid

Green Car Congress

The NZN concept relies on high energy density storage systems incorporated into the local grid, as well as efficient photovoltaic generation. NZN can integrate with the centralized grid. batteries); the creation of grid-enabled consumer-side energy generation appliances; and a robust set of standards and protocols.

A123 Systems to supply 1MW Li-ion grid storage system to Maui Electric Company; 2MW system for NSTAR demonstration

Green Car Congress

Li-ion battery maker A123 Systems will supply a Grid Battery System (GBS) to Maui Electric Company (MECO), a utility serving residents and businesses on the islands of Maui, Lanai and Molokai in Hawaii. The system, NSTAR’s first battery energy storage project, is proposed for installation at a substation in Medway, Mass.

Pike Research forecasts worldwide grid energy storage spending to reach $22B by 2021, down from 2010 forecast of $35B

Green Car Congress

In its new report Energy Storage on the Grid (ESG), Pike Research forecasts that global spending in the ESG market will reach a little over $22 billion over the next 10 years. Electric grids require balance in order to function properly. Energy storage on the grid is reaching a turning point. Earlier post.).
