Energy From Waste Water


svctss b

stanford logoNitrogen pollution is a major environmental threat that depletes oxygen in aquatic ecosystems that leads to "dead zones". The number of "dead zones" worldwide has nearly doubled every decade since 1960; many are so big they can be seen from space. Wastewater treatment facilities are facing increasing pressure to reduce nitrogen discharge, yet manage rising energy costs. The conventional method for reducing nitrogen is effective but imposes major costs and consumes energy. Yaniv will present a new wastewater treatment process that removes and recovers energy from nitrogen waste - something that has not been done before.

IEEE 1588 - Precision Time Protocol on the Smart Grid

Rod Kirk 2Behind every advancement in the areas of renewable energy and energy management, are some underlying technologies which help make those advancements possible. The IEEE 1588 Precision Time Protocol is one of those underlying technologies which is helping to make the Smart Grid a reality. This presentation will provide an overview of this technology and some of its uses in the Smart Grid.

A Presentation on Renewable Energy

by Dr. Bryan Hannegan
Vice President of Environment & Renewables at EPRI (Electric Power Research Institute)

epri logo 1Come join us for an insightful evening with Dr. Bryan Hannegan. Dr. Hannegan, Vice President, Environment and Renewables for the Electric Power Research Institute (EPRI), leads the teams responsible for EPRI’s research into technologies and practices that enable cleaner and more efficient renewable power generation, and reduce the environmental footprint associated with electric power generation, delivery and use. In addition to his work leading Environment and Renewables, Dr. Hannegan also served as Vice President, Generation for EPRI during 2008-2009 with a focus on enabling technologies for reliable and sustainable fossil generation.

Photovoltaic Technologies and the Solar Efficiency Race

 svctss b

circle arrow graphicThe Solar industry is engaged in an intense technology race to produce the most efficient solar cells. This solar efficiency race has intensified as a response to the declining price of crystalline silicon modules and panels from China. More efficient solar cells justify a higher panel price. 



  • How does efficiency affect the ROI over the life of the panel for the solar consumer?  
  • Are the solar manufacturers investing in the right technology to win the race? 
  • Does the winner in this efficiency race win the competition for consumer dollars?
  • Are there other winning strategies and approaches?

Grid-Scale Energy: Beyond Betteries

An Editorial Authored By Greg Chu

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.

energy grid HareshKanathRounding out the panel was Haresh Kamath, Sr. Project Manager for EPRI.  energy grid SteveCrane “While American utilities are greatly incented to “KTLO – Keep the Lights On” which has led to risk averse investing, Kamath & Rastler have described 10 specific business cases for grid-scale energy storage which have attracted attention from the venture capital and investment community.  Kamath noted that for certain off-grid applications, the newer energy storage technologies, when paired with solar, have the potential to “leapfrog” the current grid which many have observed to be little changed over the past 100 years.


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.”
