Your Electric Car as a Battery in the Grid

Paul%27s%20Civic%20-%20smaller.jpg Electric and hybrid cars could act as energy stores for the power grid when not being driven. New Scientist reports that researchers from the University of Delaware are using a new prototype by AC Propulsion to store or supply grid electricity (Washington DC got a first dose in October). If hundreds or thousands of owners opt into the system, the efficiency of power distribution could improve. A lot. The average US car is driven one out of every 24 hours. Combustion-powered cars are useless off the road. But plug-ins could act as backups to the grid while idle.

 

“Storage is golden for power companies because it is hard to do,” [Willet] Kempton told New Scientist, who notes that the cost of storing excess electricity means that there is only capacity for around 1% of yield in the US and UK. Storage is particularly important for renewable energy because power supplied by the Sun, the oceans, or the wind, is often irregular.

 

Each plug-in can provide $4,000 of storage to an energy company per year, at a cost of $600 to install the high-power connection system. Energy companies need to pass on some of their savings to encourage drivers to help out, says Kempton… Hmm. Technology might be the easy part.

LESS DREADING, MORE DOING

This is the rubber-meets-road moment: the early days in our first fundraising drive since we took a big swing and merged with CIR to bring fearless investigative reporting to the internet, radio, video, and everywhere else that people need an antidote to lies and propaganda.

Donations have started slow, and we hope that explaining, level-headedly, why your support really is everything for our reporting will make a difference. Learn more in “Less Dreading, More Doing,” or in this 2:28 video about our merger (that literally just won an award), and please pitch in if you can right now.
