Net Electricity Load in Calif. Is 5 Years Ahead of Schedule On January 11, 2015, a rather unremarkable Sunday earlier this month,
That means that CAISO is operating the grid, this month, at net load (that is the system demand less solar and wind generation) more than five years ahead of forecast.
California needs more energy storage to match the duck curve Experiencing this net load years ahead of the CAISO forecast has placed not the California grid in crisis. The state's grid has sufficient flexibility today to accommodate the rapid rise of solar power,
the utilities and CPUC should accelerate procurement of energy storage to match the accelerating duck curve.
With the energy storage procurement cycle in progress, let open the long-duration energy storage market in 2015.
Long-duration energy storage offers both the benefits of grid flexibility similar to flexible gas plants, and the reuse of zero-marginal-cost midday solar during the evening energy ramp.
Long-duration energy storage unique functionality uncaps the limits to growth of solar in California--and beyond.
Less than a week before the January 11 daily-duck-curve milestone, Governor Jerry brown used his 2015 inauguration speech to call for a 50 percent renewable energy future in California.
Beyond air quality and climate change mitigation benefits, California abundant renewable energy resources provide energy with zero marginal cost and zero fuel price volatility to our citizens,
limiting rate shocks into the future. California energy agencies are already collaborating to accelerate penetration of energy storage.
Several promising long-duration energy storage technologies are now in early commercial operation homegrown in California with support from the California Energy Commission and the U s. Department of energy.
The CPUC can pull out the playbook that bestowed California with an abundance of solar energy and use it again with energy storage.
Waiting to see which technologies become bankable in 2018 for 2020 delivery is unwise and unnecessary.
we need to use the current CPUC-sponsored energy storage procurement process to bring bankable, long-duration energy storage technologies to market so that they can deliver at scale in 2018--not sometime in the next decade.
Scale drives cost reduction for storage We are already witnessing the impact of manufacturing scale on cost for lithium-ion batteries being bid into the electricity market.
A variety of emerging long-duration energy storage technologies will also experience the rapid cost reduction that inevitably follows commercial scale.
Pay attention to what happened with solar--many of those folks are now working in energy storage. In both my consulting practice and in my pro-bono work with Calcharge
I have had the opportunity to see inside the proto-factories of a range of emerging long-duration energy storage technologies,
all of which have demonstrated major engineering progress. What they need next is a commercial contract of modest scale to prove bankability.
What is the opportunity in 2015 to build the market for energy storage in line with the accelerating duck curve?
Utility contracts from the current round of energy storage procurement can provide the market pull for long-duration energy storage technology.
With the energy storage procurement cycle in progress, let open the long-duration energy storage market in 2015.
As solar energy production drops off, CAISO forecasts a 14,000-megawatt resource ramp in 2020 on that date.
The four-to seven-hour ramp period during the afternoon and evening is well within the scale of long-duration energy storage.
However, CAISO did experience multiple days with negative real-time energy pricing during 2014 demonstrating the limitations to system economics given today substantial supply of inflexible generation participating in the energy market.
Since Christmas week 2013, the system operator has been helpfully posting actual net load. You can find the daily duck as the last chart here,
The year for energy storage procurement in CAISO CAISO is performing the role for which it was created:
2015 is the year to open the market for long-duration energy storage. To avoid the perverse outcome of curtailment of zero-marginal-cost, greenhouse gas-free renewable resources,
we need to absorb gigawatt-hours'worth of midday solar energy for reuse later in the day or the week.
we have the abundant solar and wind resources, the innovative companies, and the open energy storage procurement proceeding that can, at a modest scale, kick-start the long-duration energy storage market.
My request to the utilities: scour the bidder landscape, pick a variety of technologies, teach the companies the ins and outs of your contracting processes,
Light technology is now an active area of research in energy, health and agriculture. First lighting the way In the late 1800s

Light emitting diodes (LEDS) are now everywhere from consumer electronics like smart phones to light bulbs for home lighting.
In recognition of this energy saving invention, they received the Nobel prize in Physics last year. Light was recognized also in the Nobel prize category of Chemistry last year for light-based microscopy tools that use a few tricks to sense the presence of a single molecule.
in agriculture, more effective harvesting of solar energy and its conversion into heat via greenhouses could enable year-round production as well as access to crops not currently available in certain climates.

Shes designed a village-scale desalination system that runs on solar power. Since her system is powered by the sun,
however, will require extremely low-power sensors that can run for months without battery changes or, even better,
that can extract energy from the environment to recharge. Last week, at the Symposia on VLSI Technology And circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it
even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.
Moreover, the researcherschip achieves those efficiency improvements while assuming additional responsibilities. Where its predecessors could use a solar cell to either charge a battery
or directly power a device, this new chip can do both, and it can power the device directly from the battery.
All of those operations also share a single inductor the chip main electrical component which saves on circuit board space

#Nanogenerator harvests power from rolling tires A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction.
An innovative method of reusing energy, the nanogenerator ultimately could provide automobile manufacturers a new way to squeeze greater efficiency out of their vehicles.
which is the first of its kind, in a paper published May 6, 2015, in the journal Nano Energy("Single-electrode triboelectric nanogenerator for scavenging friction energy from rolling tires").
Xudong Wang has developed a new way to harvest energy from rolling tires. The nanogenerator relies on the triboelectric effect to harness energy from the changing electric potential between the pavement and a vehicle's wheels.
The triboelectric effect is the electric charge that results from the contact or rubbing together of two dissimilar objects.
Wang says the nanogenerator provides an excellent way to take advantage of energy that is usually lost due to friction."
"The friction between the tire and the ground consumes about 10 percent of a vehicle's fuel,
"That energy is wasted. So if we can convert that energy, it could give us very good improvement in fuel efficiency."
"The nanogenerator relies on an electrode integrated into a segment of the tire. When this part of the tire surface comes into contact with the ground,
the friction between those two surfaces ultimately produces an electrical charge-a type of contact electrification known as the triboelectric effect.
The movement of electrons caused by friction was able to generate enough energy to power the lights
supporting the idea that energy lost to friction can actually be collected and reused.""Regardless of the energy being wasted,
we can reclaim it, and this makes things more efficient, "Wang says.""I think that's the most exciting part of this,
how to save the energy from consumption.""The researchers also determined that the amount of energy harnessed is directly related to the weight of a car,
as well as its speed. Therefore the amount of energy saved can vary depending on the vehicle -but Wang estimates about a 10-percent increase in the average vehicle's gas mileage given 50-percent friction energy conversion efficiency."
"There's big potential with this type of energy, "Wang says.""I think the impact could be huge."

#New lithium ion battery is safer, tougher, and more powerful Lithium ion batteries (LIBS) are a huge technological advancement from lead acid batteries
which have existed since the late 1850. Thanks to their low weight, high energy density and slower loss of charge when not in use, LIBS have become the preferred choice for consumer electronics.
Lithium-ion cells with cobalt cathodes hold twice the energy of a nickel-based battery and four times that of lead acid.
Despite being a superior consumer battery, LIBS still have some drawbacks. Current manufacturing technology is reaching the theoretical energy density limit for LIBS
and overheating leading to thermal runaway i e. enting with flameis a serious concern. South korean researchers at the Center for Self-assembly and Complexity, Institute for Basic Science (IBS), Department of chemistry and Division of Advanced Materials science at Pohang University, have created a new LIB made from a porous solid
which greatly improves its performance as well as reducing the risks due to overheating("Solid lithium electrolytes based on an organic molecular porous solid").
"Since 2002 there have been over 40 recalls in the US alone due to fire or explosion risk from LIBS used in consumer electronic devices.
These types of batteries, in all of their different lithium-anode combinations, continue to be an essential part of modern consumer electronics
despite their poor track record at high temperatures. The Korean team tried a totally new approach in making the batteries.
According to Dr. Kimoon Kim at IBS, e have investigated already high and highly anisotropic directionally dependent proton conducting behaviors in porous CB 6 for fuel cell electrolytes.
It is possible for this lithium ion conduction following porous CB 6 to be safer than existing solid lithium electrolyte-based organic-molecular porous-materials utilizing the simple soaking method
Current LIB technology relies on intercalated lithium which functions well, but due to ever increasing demands from electronic devices to be lighter and more powerful,
investigation of novel electrolytes is necessary in order. The new battery is built from pumpkin-shaped molecules called cucurbit 6 uril (CB 6)
which are organized in a honeycomb-like structure. The molecules have an incredibly thin 1d-channel,
The physical structure of the porous CB 6 enables the lithium ions to battery to diffuse more freely than in conventional LIBS
and exist without the separators found in other batteries. In tests the porous CB 6 solid electrolytes showed impressive lithium ion conductivity.
To compare this to existing battery electrolytes, the team used a measurement of the lithium transference number (tli)
+which was recorded at 0. 7-0. 8 compared to 0. 2-0. 5 of existing electrolytes.
They also subjected the batteries to extreme temperatures of up to 373 K (99.85°C), well above the 80°C typical upper temperature window for exiting LIBS.
In the tests, the batteries were cycled at temperatures between 298 K and 373 K (24.85°C and 99.85°C) for a duration of four days and after each cycle the results showed no thermal runaway and hardly any change in conductivity.
Various conventional liquid electrolytes can incorporate in a porous CB 6 framework and converted to safer solid lithium electrolytes.
Additionally, electrolyte usage is limited not to use only in LIBS, but a lithium air battery potentially feasible.
What makes this new technique most exciting is that it is a new method of preparing a solid lithium electrolyte
which starts as a liquid but no post-synthetic modification or chemical treatment is needed t

and convert them back into more energy, extending a smartphone's battery life by as much as 30%.
%Announced as part of an upcoming Kickstarter fundraising campaign, the technology, which Nikola's designers engineered into a special case made for Apple's iphone,
reportedly harvests the electromagnetic radiation transferring to and from mobile phones and converts it into direct current (DC) electrical energy,
which is recycled then back into the phone's battery.""Nikola Technology efficiently converts RF signals like Wi-fi, Bluetooth,
"The result is usable energy that can provide power to mobile devices wirelessly.""Though not perfect by any means, Nikola energy-capturing case holds promise For a sponsorship contribution of $99,
early supporters of the project will gain exclusive first-issue access to the case, which doesn't so much charge an iphone actively as it does extend its normal battery life.
Still, the case's novelty, and more importantly its longer-term potential, is what stands to inspire a new generation to take advantage of energy inefficiency and waste.
One major drawback to the technology is that its relatively slow to harvest energy, and the case itself doesn't contain an actual battery of its own to store excess charge.
At the same time the case itself is small and form-fits well to the iphone, acting as an all-in-one battery extension package that's sleek, discreet and unobtrusive."

and its unveiling is sure to inspire many curious folks to take a closer look at the energy discoveries of the man behind the Nikola name, Nikola Tesla.
Tesla's pie-in-the-sky ideas admittedly led to some pretty amazing breakthroughs in energy technology.
