Go straight until you reach the energy storage tower, then turn left.

Explaining what energy storage is can be difficult sometimes.  Leave explaining the benefits for another day.  If you store air in a balloon, it expands.  If you store boxes in a warehouse, the shelves get full.  But, if you store energy, for most mediums you usually still have a paneled or enclosed box still sitting there, unchanged to any of…

Rebuilding "smart" after Sandy with new NEMA publication

Rebuilding "smart" after Sandy with new NEMA publication

Superstorm Sandy highlighted the fragile nature of our nation's electric grid. One thing is clear: our grid needs some updating. In an effort to assist federal, state, and local policymakers with solutions to harden the nation’s electric grid, improve its resiliency to withstand severe weather, and improve energy efficiency, NEMA published Storm Reconstruction: Rebuild Smart. As communities continue to rebuild…

What are the driving forces behind expansion of LVDC beyond Data Center Applications?

What are the driving forces behind expansion of LVDC beyond Data Center Applications?

The ability to directly link between photovoltaics or energy storage mechanisms and direct current (DC) rated utilization equipment is an attractive option to avoid the potential energy losses and heat generation associated with power conversion from DC-to-AC-to-DC.  Many pieces of utilization equipment, particularly IT, home electronics and appliances, and office equipment are actually operated by DC supplied from individual power…

Comparing apples and oranges and energy storage

Comparing apples and oranges and energy storage

As more and more grid energy storage projects are planned, how do you select the best technology for the need, or even begin to report and compare performance?  Comparing pumped hydro, compressed air, sodium sulfur batteries, flow batteries, lead acid batteries, lithium ion batteries, flywheels, and capacitors is akin to comparing apples to oranges to pears to kumquats to….you get…

Calling all NEMA lithium-ion battery manufacturers

Calling all NEMA lithium-ion battery manufacturers

Now is the time for NEMA members in the lithium-ion battery industry to get involved in IEC nano standards work. Balloting of a new work proposal in IEC TC 113 is underway for electrochemical characterization of cathode nanomaterials for lithium-ion batteries. It’s crucial that US industry get involved now, through the IEC TC 113 US Technical Advisory Group. The future…

35% Renewables – The Good News and the Better News

35% Renewables – The Good News and the Better News

The Western Wind and Solar Integration Study (WWSIS), released yesterday by the National Renewable Energy Lab, proclaims the good news: integration of 30% wind and 5% solar is “feasible” in the west. There are some minor caveats, notably a dramatic increase in forecasting accuracy along with increasing generator scheduling granularity from hourly to several times an hour. Conspicuous in absence…

News Roundup

News Roundup

Reading news is one of my favorite hobbies (it even probably ranks higher than watching TV). Below are some recent items related to the electrical industry that I found interesting. Captain Planet would approve: USA Today says that Oregon is getting the first U.S. commercial wave energy farm. I was surprised by the size of the buoys; the first one…

Where Do You Plug-in Your Electric Vehicle?

Where Do You Plug-in Your Electric Vehicle?

Plug-in vehicles, either hybrid or all electrical, are just around the corner.  The big question is how are they going to be recharged? The answer depends a lot on who you are asking.  In the US the most significant effort is made by the Society of Automotive Engineers (SAE International).  A number of standards are in the works to cover…
