There has been a lot of talk about the challenges of unreliable alternative energy such as wind and solar. Wait a minute you say, “they aren’t unreliable,” but alas, yes they are. Consider if you will that wind doesn’t always blow, and at night guess what? No Sun, and in the winter time the days are shorter, depending on where you live they might be a lot shorter. So, what’s the plan Stan?
Well, there are ideas of pumping water back up hill behind a dam with the excess energy when you have it, and when you don’t you let the water back out of the dam using the hydroelectricity you can make from it. Or you could pressurize an underground cavity and then let the pressure out to turn turbines when you wanted the energy back. Yes, you’d lose some each time you convert that energy into work or back into energy again, but it is one way to play it.
What if you charged up your car batteries (assuming an electric car in your garage) when the energy was available, you could then when you needed it later use that energy stored in the batteries to power up your home without any massive energy storage infrastructure as I described above, which are by no means the only other centralized energy storage strategies.
In JDP Online News there was an interesting article titled; “Six Nissan Leaf all-electric vehicles power an office building,” by John Hofilena (December 11, 2013). The article stated;
“With Nissan testing out its ‘Vehicle-To-Building’ power system, at least we will all rest well knowing the answer to the age-old riddle “How many Nissan Leaf vehicles does it take to power an office building?” The answer, according to the Japanese car manufacturer, is a tidy half-dozen. Nissan has carried out a successful early field test of a system that will allow companies to regulate their electricity bills using the batteries of Nissan LEAFs used by their staff to commute to work.”
Indeed, when I read that I thought to myself; “Well then self, a company with a vehicle fleet of electric trucks or electric cars could use this strategy for disaster preparedness and disaster planning.” You see, back a decade or so ago, I was in the franchising business and we franchised mobile car wash trucks around the country, most of our franchisees noted that 70% or more of their business were fleets of vehicles. Even back then many government agencies and large corporate fleets were experimenting with electric delivery and service vehicles.
Apparently, Nissan is well ahead of the curve on this strategy and storage strategy. I hope you will please consider all this and think on it from a distributive and centralized energy storage and usage strategy.
