#Germany and Canada Are Building Water Splitters to Store Energy Germany which has come to rely heavily on wind

Electrolysis has advantages over some other energy storage options. It can be deployed almost anywhere it can store vast amounts of energy
and the hydrogen can be used to replace fossil fuels not only in electricity production but also in industry and transportation
Even so it has long been considered a relatively lousy way to store energy because of its low efficiency about 65 percent of the energy in the original electricity is lost.
When it opens next year it will have the capacity to produce 650000 kilograms of hydrogen a year the energy equivalent of 650000 gallons of gasoline.
It s also more versatile than the cheapest way to store energy: pumping water up a hill
So an important question is how to minimize the energy it takes to grow these crops.

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,
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,
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.

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,
and the open energy storage procurement proceeding that can, at a modest scale, kick-start the long-duration energy storage market.

#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."
"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 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.
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.

and convert them back into more energy, extending a smartphone's battery life by as much as 30%.
"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.
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.
"Tesla's visions of wireless energy threatened the military-industrial complex; were sabotaged his ideas? The official Kickstarter campaign for the case is expected to be launched in June,
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.
Of particular interest was Tesla's dream of developing a way to transmit energy wirelessly using only air as a medium.

because water purification processes are very energy-demanding using current technology. We're particularly pleased at being able to produce
