Startups and researchers have been striving to create a rechargeable, grid-scale energy storage system using zinc, one of the world’s cheapest metals, but they tend to break down after just hundreds of charge-discharge cycles, and coming up with new technology innovations to overcome this remains a challenge.[read more]

The Era of Big Dams is Still Over, Even With the Water Bond

September 13, 2014 by NRDC Switchboard

Dams and the Water Bond

 

The potential for new water storage in California is in the news because of Proposition 1, the $7.5 billion water bond on California’s November ballot, which includes $2.7 billion for new groundwater and surface storage, and an additional $800M for groundwater remediation projects.[read more]

Advanced Energy Technology of the Week: District Energy

September 12, 2014 by Matt Stanberry

District Energy

District energy systems produce steam, hot water, and/or chilled water at central plants and, through a network of insulated pipes (often underground), distribute the steam or water to multiple buildings. District energy plants often include power generation, typically CHP, which further increases overall efficiency.[read more]

Tesla and Toyota

While electric vehicles have experienced a marketplace renaissance in the last decade, hydrogen fuel-cell vehicles have not. Multiple models of EVs (like the Tesla and Nissan Leaf) and plug-in EVs (like the Chevy Volt) are selling in this country and around the world, but there are no commercial consumer FCVs yet.[read more]

Utility 2.0: NY's New Business Model Should Properly Value the Costs and Benefits of Distributed Energy Resources

August 27, 2014 by EDF Energy Exchange

New York's Utility Future

As we’ve mentioned before, New York is changing how it evaluates and compensates electric utilities. One goal of this change is increased consumer engagement, which makes customers allies in the development of a more reliable, resilient, and ‘smart’ electric grid.[read more]

Distributed Marginal Price: The New Metric for the Grid Edge?

August 27, 2014 by Jeff St. John

Metrics for the Grid Edge

The grid is changing from a one-way, centralized electricity delivery system to a distributed, networked system for generating, storing and consuming power, and the technology is changing a lot faster than the economic and regulatory systems that govern it.[read more]
