Cheers and Jeers: Reality and the EPA

August 9, 2013 by Mark Green

Kudos to the EPA for deciding to give the oil and natural gas industry more time to install emissions controls on storage tanks. Phasing in the deadline for controls on volatile organic compounds emitted by storage tanks instead of the original deadline is encouraging.[read more]

Electricity Storage and Duck Graphs

 

An aptly named picture – the “duck graph” – is captivating the California energy policy world. It depicts electricity demand net of projected renewable generation (“net load”) on a representative day in the not too distant future. One point of concern is the duck’s long neck.[read more]

Germany's Energy Storage Subsidy Is No Solar Miracle

German Solar Energy Storage

In April, we asked if a German subsidy on energy storage could replicate the German solar miracle, but for batteries and energy storage systems this time. The answer is no. In fact, there were fewer than 500 applications for the energy storage loan as of two weeks ago.[read more]

Distributed Generation, Electricity Storage, and the Utility of the Future

If the market for storage grows up “inside the meter”, rather than on the utility side of the meter, there is good reason to believe that utilities will have a hard time getting that market back.[read more]

If the highest objective of new energy technology is to provide greater flexibility to manage the electricity grid in ways that society deems most beneficial, then no technology—not wind, not solar, not biomass, not new transmission technology—is more important to develop than energy storage technology.[read more]

Smart Grids and Smart Cities – Same Problems, Same Solutions?

April 9, 2012 by Christine Hertzog

The world population is expected to soar to more than 9 billion people by 2050.  Roughly 70% of the global population will live in cities, which today consume 70% of global energy supplies.  That’s a concern for electric and water utilities, but there are ways to address these concerns.  The best Smart Grid planning...[read more]

What’s Missing In Smart Grid Roadmaps

Smart Grid technology roadmaps help utilities plan for grid modernization. However, they must address changes in utility cultures, particularly the investor-owned utilities (IOUs), and these changes will require support in the form of new regulatory policies.[read more]

Developing Low Cost Batteries For Energy Storage

Long term, therefore, the outlook for wind energy is good—as is the outlook for the electricity storage technology necessary to balance wind's inherently variable nature. As electricity costs begin to rise, power purchasers will find the long term, stable electricity prices that wind projects offer more attractive. As they do, attention will turn to how best to balance the variable nature of that electricity in an environment in which natural gas cannot be counted on to deliver a low cost, long term balancing solution.[read more]

Super Hot Salt: The Newest Energy Storage Innovation?

 Policymakers and energy industry experts often talk about clean energy as though it isn’t reliable. In fact, while an MIT study recently found the existing grid would probably be up to the challenge of absorbing clean energy, intermittency does present a real challenge that renewables must address to get to high levels of...[read more]

Massive Battery System Captures Wind Power

December 6, 2011 by Silvio Marcacci

One of the biggest challenges facing wind energy is intermittency. Wind often blows strongest when power demand is lowest, and weakest when electricity is needed the most. Because today’s power grid needs electricity to be consumed the moment it’s generated, that means wind turbines send energy to the grid half as often as an average coal plant. What if wind farms could store the power that isn’t needed right away and sell it later when demand is high? energyNOW! correspondent Patty Kim visited an energy storage system built alongside a wind farm in the heart of coal country.[read more]
