The Future of Energy Storage — ‘Sisyphus Railroad’

 

In research there is evolution, revolution and — sometimes — what I call “retro revolution,” which happens when old methods have new applications. All three are in play in the world of electricity, and are affecting storage.

 

The inability to store electricity has been a challenge since the time of Thomas Edison. Electricity is made and used in real time, putting huge pressure on utilities at particular times of the day. For much of the East Coast in summer, for example, the peak is in the evening, when people come home from work or play, crank up the air conditioning, flip on the lights, the TV and start cooking. In many cities, the subways operate at peak and the electricity supply is stretched.

 

Traditionally, there have been two ways to deal with this. One is that utilities have some plant on standby, in what is called “spinning reserve,” or they have gas turbines ready to fire up.

My own favorite — and one likely to appeal to many because of its safety and mechanical efficiency — is an electric train that stores energy by running up a track and then down to generate power.
