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.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air. Twenty of these solar panels could provide electricity and heat for one family for an entire winter. A traditional solar panel converts between 18 to 20% of the solar energy into electricity. —Johan Martens.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost. —Huskinson et al. Background.

BMW i ChargeForward Program to demo contribution of intelligent EV charging to grid efficiency

Green Car Congress

At the Consumer Electronics Show in Las Vegas, BMW announced the BMW i ChargeForward Program—a pilot study to be undertaken by the BMW Group Technology Office, together with Pacific Gas & Electric Company (PG&E). Grid efficiency through managed charging, combined with a used EV battery “second-life” system.

CPUC approves SDG&E pilot EV grid integration project; 3,500 charging stations at 350 sites, dynamic pricing

Green Car Congress

With rates encouraging off-peak charging, vehicles will be efficiently integrated onto the grid, helping to avoid on-peak charging that drives the need to build more power plants and other electric infrastructure. The cost of the original proposal and the PS was about the same, about $103 million. Background.
