On November 13, 2012, MIT/Stanford Venture Lab (VLAB) sponsored “Grid Energy Storage: Beyond Batteries”, a panel event to discuss grid-scale energy storage.  After treating the audience of about 300 investors, entrepreneurs, technologists and thought leaders to a short harmonica solo, Eric Wesoff from Greentech Media proceeded to outline the landscape around grid-scale energy storage and moderate the panel around future directions in grid-scale energy storage.

energy grid panelWesoff overviewed current technologies, the complicated value chain which generates and delivers energy to end users, the cleantech investment climate, and the environmental /government mandated need for clean, renewable energy which can only be enabled by grid-scale energy storage.

Currently, grid scale energy storage is dominated by pumped hydro.  “For grid applications, it’s all about cost per kilowatt hour” said, Abe Yokell, panelist and Partner at Rockport Capital Partners who foresees grid-scale energy storage for certain, specific use cases such as where local energy storage in dense urban environments is less expensive than running in new utility lines.  Philip Gleckman, CTO of Areva Solar agreed “Grid Storage with batteries is not inevitable…Thermal storage is available costing one tenth of the best battery technology.  Justin Raade, CEO of Halotechnics, Inc described how his company is working on grid-scale thermal storage as low as $25/kw-hr.

Indeed, two grid-scale energy storage companies were represented on the panel.  Lightsail Energy of Berkeley, CA and Aquion Energy of Pittsburgh, PA shared their experiences as start-ups entering a heavily regulated, highly fractioned, risk averse environment.

Mike Lee, Financial Advisor, on why Morgan Stanley sponsored the panel, “We like sponsoring these sorts of events in order to bring people together to facilitate growth in this community.”  Another perspective was offered by Laurie Manning, volunteer with the MIT/Stanford Venture Lab “We have to look beyond our current economic crisis to greater environmental issues. Superstorm Sandy showed this.  We need greater urgency before it’s too late.”
