CleanTechies caught up with Maurice Gunderson, senior partner of energy and materials at CMEA Capital, for some energy storage perspectives.
CleanTechies: You were an investor in A123 Systems. When will bulk storage arrive?
Maurice Gunderson: Bulk storage needs a little bit of definition. The kind of thing that A123 is doing is here now, and that’s a very high power storage for grid stabilization. And that makes sense in a lot of parts of the country. I make a distinction between that and very large bulk energy storage, which is intended to store power for very long periods of time, such as from wind turbines, and then release it over relatively long periods of time.
So the answer is there’s no real good battery solutions yet, but there’s a lot of smart people and a lot of money working on the problem and we’re going to see things emerging here within the next few years. The really practical ways to do very large storage right now come down to pumped storage. If nature gives you a canyon and environmental considerations don’t stop you from damming it up, you can make a very nice pumped storage facility. But that only exists when it occurs naturally. So there’s not a lot of places where you can count on building out new capacity of that type. (more…)
