[center]Diamonds Are A Battery’s Best Friend — Potential
Lithium-Ion Battery Breakthrough[/center]
August 28th, 2017 by Steve Hanley
SNIPPET:
Dendrites are the enemy of lithium-ion batteries. As ions
transfer back and forth between the anode and the cathode in
those batteries, they can leave behind tendril-like buildups
called dendrites. Similar to stalactites that form inside a
cave, these battery buildups (dendrites) are one of the main
causes of lithium battery malfunction.
Lithium is the ideal material for cathodes in terms of energy
storage potential, but pure lithium cathodes suffer from
significant dendrite formations. To solve that issue, battery
makers have started blending the lithium with graphene. The
resulting compound inhibits the formation of dendrites but also
significantly reduces the energy storage capacity of the
cathode. A pure lithium cathode is capable of storing 10 times
as much electrical energy as a cathode made of lithium and
graphene.
Researchers at Drexel University, working closely with
colleagues at Tsinghua University in Beijing and Hauzhong
University of Science and Technology in Wuhan, China, may have
found a way to inhibit the formation of dendrites and allow
cathodes to be made with a higher percentage of lithium. Their
discovery involves adding nanosized diamonds to the electrolyte
inside the battery.
On August 25, Professor Yury Gogotsi and his research team from
the Department of Materials Science and Engineering at Drexel
published their research in the journal Nature Communications.
Entitled “Nanodiamonds Suppress Growth of Lithium Dendrites,” it
describes how diamond particles 10,000 times smaller than the
diameter of a human hair curtail the electrochemical deposits
that form dendrites.
Agelbert NOTE: The micrometre (International spelling as used by
the International Bureau of Weights and Measures; SI symbol:
μm) or micrometer (American spelling), is also commonly
known as a micron. One μm equals one millionth of a metre
(or one thousandth of a millimetre, 0.001 mm, or about 0.000039
inch). The width of a single human hair ranges from
approximately 10 to 200 μm.

Tesla is sending its Powerwall system to Puerto Rico as the
island deals with widespread power loss in the wake of Hurricane
Maria.
According to Electrek, the company has been quietly shipping
hundreds of battery packs to be paired with solar panels to
Puerto Rico ever since the storm cleared.
Fortune reported that Tesla employees are currently on the U.S.
territory installing the batteries and repairing solar systems,
as well as coordinating efforts with local organizations.
Much of the island's 3.4 million American citizens are currently
without power and disconnected from modes of communication.
Officials estimate that some areas will not see their power
restored for months. As Climate Nexus pointed out, "the future
of the island's bankrupt and corrupt utility and its
fossil-fuel-heavy colonial legacy are now top of mind as experts
and officials begin to tackle the best way to restore power and
rebuild the island's power grid."
While there is still a long way to go rebuild, Tesla's batteries
will help enable the island's generation of clean and renewable
solar energy in the interim and in the future. [img width=50

The company previously made headlines for helping Model S and
Model X owners in Florida escape Hurricane Irma by extending the
battery range of its cars.
Tesla CEO Elon Musk has also personally donated $250,000 to the
relief effort, Electrek noted.
HTML http://www.pic4ever.com/images/thankyou.gif
A number of companies and business leaders have contributed to
hurricane relief efforts. Fellow billionaire mogul Richard
Branson, who faced two damaging hurricanes in a row from his
home in the British Virgin Islands, has met with government
representatives from Britain and the U.S. to set up a green fund
to rebuild the hurricane-wrecked Caribbean.
"As part of that fund we want to make sure that the Caribbean
moves from dirty energy to clean energy," Branson also told
Thomson Reuters Foundation.
"If all that money could be invested in clean energy, in
powering the world by the sun and by the wind, where we won't
have to suffer these awful events in the future, how much better
than having to patch up people's houses after they've been
destroyed?" the Virgin Group founder said.

LAST UPDATED ON OCTOBER 3RD, 2017 AT 7:41 PM BY TIBI PUIU
SNIPPET:
Just a touch of asphalt is enough for high-capacity lithium
metal batteries to charge 10 to 20 times faster than the
commercially available lithium-ion variety. Additionally, the
novel batteries last longer and are safer than current
alternatives.

Agelbert NOTE: Off the shelf Lithium ion batteries now use
carbon anodes, so this modification is not that big or expensive
of a change. That said, I am a bit skeptical because faster
charging does not give any guarantee of avoiding dendrite
formation that degrades the batteries. The scientists claim the
asphalt doping prevents dendrite formation. Maybe during the
charge itself, but what about while it is sitting? I am not
convinced by their assurances. Repeated faster charging might
even cause the dendrites to grow faster, so I will adopt a wait
and see attitude in regard to this innovation.

SNIPPET:
How can you achieve such a low cost per kWh? ???
StorEn TechnologyCost is crucial for the adoption of energy
storage. Our work is about bringing evolution to the technology
with the objectives to improve performance as a way to drive
down costs. We developed a disruptive battery technology based
on both chemical and engineering solutions, leading to a 50%
cost reduction. We are targeting a price of $400/kWh with a 25
year duration with no decay. :o [img width=25
height=30]
HTML http://www.createaforum.com/gallery/renewablerevolution/3-080515182559.png[/img]
The great breakthrough is our innovative high-power electrodes
made with nanomaterials and a proprietary functionalization
process. With this innovation we have doubled power density over
traditional batteries, while running at low pressure.
The ability to run at low pressure means that less of the
battery’s own energy is required to run the pumps, hence
round-trip efficiency is increased. Additionally, duration of
the battery is also increased. To support the electrochemical
activity, we couple our Hi-Power Nano-Structured Carbon
Electrode to our MULTIGRID™ multipoint flow distribution to
deliver an increase in power in excess of 50%.
We also wanted to make a battery that was virtually
maintenance-free, like a car battery, for trouble-free
operations and reduced Total Costs of Ownership. We developed
two proprietary systems, RESAFE™ and EQUILEVELS™. These two
systems support a battery that is virtually maintenance-free by
eliminating service activities.
Our battery can be monitored remotely with our built-in BMS
(Battery Management System). Therefore we implement a shift from
scheduled on-site inspections to a maintenance-on-demand model.
For example, if one of our batteries was installed in a remote
telecommunications tower for power back-up, remote monitoring
can reduce or eliminate the need for periodic on-site visits,
which can translate in significant cost savings.

[move][font=comic sans ms]blueSG[/font] network of 1,000 shared
electric Bluecar vehicles in Singapore
HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714191258.bmp[/move]
THE SERVICE
Launched in the year of 2017, BlueSG offers a new smart and
affordable mobility option to all Singaporeans, complementing
public transport.
BlueSG members will have access to a network of 1,000 shared
electric Bluecar vehicles, 24/7, at self-service stations
located in public housing, city center and commercial estates
around Singapore. The service is point to point, which means
there’s no need to return the car to your starting point, nor to
bear the cost of maintenance or insurance of a own vehicle.
The BlueSG service will be available to anyone over 21 years of
age with a valid driver’s license.
BlueSG is a subsidiary of the Bolloré Group which has launched
the world’s largest and most successful car sharing, Autolib’ in
Paris. . BlueSG will become the world’s second largest EV car
sharing service.
THE PROJECT
A Request for Information (RFI) was issued in 2014 by the Land
Transport Authority of Singapore (LTA) and Economic Development
Board (EDB) and received proposals from 13 major consortia.
Bolloré Group was selected for the quality of its proposal which
complemented the public transport network, its strong track
record – 6 years of successful implementation in Paris, and its
commitment to Singapore.
On June 30, 2016, Singapore and the Bolloré Group signed the
agreement that demonstrated the Group’s commitment to fully
support Singapore’s public transport policy, through the
creation of alternative and environmentally-friendly
transportation solutions to the traditional car.
In December 2017, BlueSG car sharing service will officially be
launched with an estimate of 30 stations and 80 Bluecars.
Under the agreement, the car-sharing programme will eventually
include 500 stations equipped with 2,000 charging points. Of
these, 20 per cent (or 400 charging points) will be for public
use. The first fleet of Bluecars is also currently being
commissioned in Singapore and will be part of the 1,000 strong
EV fleet in the future.
THE BLUESG TECHNOLOGY
BlueSG is offering a one-way and all-electric car sharing
service thanks to its Bluecar vehicle equipped with Lithium
Metal Polymer (LMP®) batteries from Blue Solutions, a Bolloré
subsidiary as BlueSG.
LMP® technology is the culmination of an ambitious research and
development program started more than twenty years ago. Made of
thin films of material produced using extrusion techniques
perfected by the Bolloré Group, LMP® batteries offer high energy
density while ensuring safety of use. They provide unrivaled
autonomy and excellent performance in all weather conditions.
They are dry batteries (meaning “entirely solid”), which gives
them numerous advantages, particularly in terms of safety. Solid
electrolytes effectively reduce local pollution risks in the
event of an accident or damage to the integrity of the battery
pack. The LMP® batteries contain no solvents, no rare earth
metals, and no cobalt.[img width=60
height=40]

/>
These batteries can fulfill the needs of many different markets
and meet the two primary challenges of the energy transition:
developing clean transportation and smart energy management.
Blue Solutions holds the intellectual property rights allowing
it to manufacture and market batteries based on LMP® technology.
OUR AMBITIONS IN SINGAPORE
Thanks to the LMP® technology, the Bolloré Group decided to
develop mobility (car sharing and electric vehicles) and
stationary applications to address the environmental concerns.
The Group ambition is to go further in the development of
electro mobile solutions in particular thanks to its subsidiary
that opened its new office in Singapore in September 2017.
Indeed, in addition to the fleet of 100% electric cars and
charging points, the Bolloré Group is also establishing a new
R&D center for Asia in Singapore, and an innovation center for
partners to develop, test, and implement technological
innovations in the mobility, data analysis and batteries.
Finally, the Bolloré Group also aims to deploy in the city-state
and in Asia other modes of public transport, such as the Bluebus
and the Bluetram equipped with supercapacitors. All of these
would help create over 250 jobs in the country.

/>Tesla’s Battery in Australia Is Surpassing Expectations
[/center]
January 17, 2018

It’s just over one month since the Hornsdale Power Reserve was
officially opened in South Australia at the Hornsdale wind farm.
The excitement surrounding the project has generated acres of
media interest, both locally and abroad.
The aspect that has generated the most interest is the battery’s
rapid response time in smoothing out several major energy
outages that have occurred since it was installed.
Following the early success of the South Australia model,
Victoria has also secured an agreement to get its own Tesla
battery built near the town of Stawell. Victoria’s government
will be tracking the Hornsdale battery’s early performance with
interest.
[center]Generation and Consumption[/center]
Since there are losses associated with energy storage, it is a
net consumer of energy. This is often described in terms of
“round trip efficiency,” a measure of the energy out to the
energy in. In this case, the round trip efficiency appears to be
roughly 80 percent.
The figure below shows the input and output from the battery
over the month. As can be seen, on several occasions the battery
has generated as much as 100 MW of power, and consumed 70 MW of
power. The regular operation of the battery moves between
generating 30 MW and consuming 30 MW of power.

[center]Over the full month of December, the Hornsdale power
reserve generated 2.42 GWh of energy, and consumed 3.06
GWh.[/center]
As can be seen, the generation and consumption pattern is rather
“noisy,” and doesn’t really appear to have a pattern at all.
This is true even on a daily basis, as can be seen below. This
is related to services provided by the battery.

[center]Generation and consumption of the Hornsdale Power
Reserve over the month of December 2018. Author provided [data
from AEMO][/center]
[center]Frequency Control Ancillary Services[/center]
There are eight different Frequency Control Ancillary Services
(FCAS) markets in the National Electricity Market (NEM). These
can be put into two broad categories: contingency services and
regulation services.
Contingency Services
Contingency services essentially stabilize the system when
something unexpected occurs. These are called credible
contingencies. The tripping (isolation from the grid) of large
generator is one example.
When such unexpected events occur, supply and demand are no
longer balanced, and the frequency of the power system moves
away from the normal operating range. This happens on a very
short timescale. The contingency services ensure that the system
is brought back into balance and that the frequency is returned
to normal within five minutes.
In the NEM there are three separate timescales over which these
contingency services should be delivered: six seconds, 60
seconds, and five minutes. As the service may have to increase
or decrease the frequency, there is thus a total of six
contingency markets (three that raise frequency in the
timescales above, and three that reduce it).
This is usually done by rapidly increasing or decreasing output
from a generator (or battery in this case), or rapidly reducing
or increasing load. This response is triggered at the power
station by the change in frequency.
To do this, generators (or loads) have some of their capacity
“enabled” in the FCAS market. This essentially means that a
proportion of its capacity is set aside, and available to
respond if the frequency changes. Providers get paid for the
amount of megawatts they have enabled in the FCAS market.
This is one of the services that the Hornsdale Power Reserve has
been providing. The figure below shows how the Hornsdale Power
Reserve responded to one incident on power outage, when one of
the units at Loy Yang A tripped on December 14, 2017.
Regulation Services
The regulation services are a bit different. Similar to the
contingency services, they help maintain the frequency in the
normal operating range. And like contingency, regulation may
have to raise or lower the frequency, and as such there are two
regulation markets.
However, unlike contingency services, which essentially wait for
an unexpected change in frequency, the response is governed by a
control signal, sent from the Australian Energy Market Operator
(AEMO).
In essence, AEMO controls the throttle, monitors the system
frequency, and sends a control signal out at a four-second
interval. This control signal alters the output of the generator
such that the supply and demand balanced is maintained.
This is one of the main services that the battery has been
providing. As can be seen, the output of the battery closely
follows the amount of capacity it has enabled in the regulation
market.

Not to be outdone by its neighboring state, the Victorian
government has also recently secured an agreement for its own
Tesla battery. This agreement, in conjunction with a wind farm
near the town of Stawell, should see a battery providing similar
services in Victoria.
This battery may also provide additional benefits to the grid.
The project is located in a part of the transmission network
that AEMO has indicated may need augmentation in the future.
This project might illustrate the benefits the batteries can
provide in strengthening the transmission network.
It’s still early days for the Hornsdale Power Reserve, but it’s
clear that it has been busy performing essential services and
doing so at impressive speeds. Importantly, it has provided
regular frequency control ancillary services — not simply
shifting electricity around.
With the costs and need for frequency control service increasing
in recent years, the boost to supply through the Hornsdale Power
Reserve is good news for consumers, and a timely addition to
Australia’s energy market.

Agelbert NOTE:For smoothing electrical energy demand and
preventing appliance damaging frequency and voltage
fluctuations, no fossil fuel or nuclear power generating plant
can EVER match the lightning speed and reliability of a large
battery system.
The only thing that comes close, but still takes seconds
(causing brief frequency and voltage fluctuations that you don't
notice but your electronics certainly do not like), instead of
the lightning fast battery response of fractions of a second, is
hydroelectric power because valves can quickly force torrents of
water through pelton wheels powering electricity generators.
Battery systems are the Renewable Energy smoothing solution to
the problem of intermittent solar, wind, tide, hydro, etc.
because they provide an added guarantee of uninterrupted clean
power that totally eliminates the need for alleged "baseload"
coal or nuclear AND natural gas super expensive peaking power
plants.
This has been known by the fossil fuelers for at least a half a
century. That is why they continue to do everything they can to
stop these systems from coming online. We need fossil fuel and
nuclear dirty energy sources like like a dog needs ticks. >:(
If we survive the present Trumpism dystopic stupidity, I believe
all the excess Renewable Energy harvested from facilities that
are being built all over the world will eventually be stored,
not just in battery systems and dams, but also in potential
energy systems (massive cable suspended weights in subterranean
structures up to a thousand feet long) that can kinetically
power generators by gravity even faster than hydroelectric
power.
Many people do not realize that, at present, a great deal of
generated energy by fossil fuel and nuclear power is thrown away
in what is called "shunting". As you read in the article above,
a certain amount of power capacity HAS TO be kept off line so
that when a demand spike shows up, the frequency and voltage do
not get out of acceptable limits.
All this is because conventional polluting power sources like
coal and nuclear are TOO SLOW in the ramp up and ramp down.
HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714183337.bmp
Also, those peaking power plants that use natural gas are,
though much quicker, still too slow to avoid the huge amounts of
shunted energy thown away routinely.
Renewable Energy and battery systems have the potential to
reduce [b]shunting to a fraction of what it is today[/b] and
eventually eliminate this wasteful process altogether. Fossil
Fuelers and Nuke Pukes don't like to talk about shunting
because, aside from the polluting
piggery
HTML http://www.pic4ever.com/images/237.gif
, Shunting is
their[size=10pt] horrendously wasteful Achilles
Heel.[/size]
HTML http://www.pic4ever.com/images/290.gifhttp://www.pic4ever.com/images/nocomment.gif
In the future, I envision large battery systems as mainly a
smoothing technology used to coordinate all the Renewable Energy
coming in and storing it when there is an excess, while
providing millisecond smooth frequency and voltage instant power
until the hydroelectric and/or gravity systems come online a
second or three later. [img

HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp[/img]<br
/>The present six seconds, 60 seconds, and five minutes time
scales will be relegated to the cave man days of fossil fuel and
nuclear polluting energy sources. ;D
There is no place for slow starting dirty energy generation in

We already reported on how Tesla’s giant battery in Australia
made around $1 million in just a few days by taking advantage of
the country’s volatile energy market.
But now a new report shows how it is also eating away at the
‘gas cartel’s’ profits.

When an issue happens or maintenance is required on the power
grid in Australia, the Energy Market Operator calls for FCAS
(frequency control and ancillary services) which consists of
large and costly gas generators🦖 kicking in to
compensate for the loss of power.
These services are so costly that it can sometimes amount to up
to $7 million per day – or 10 times the regular value of the
energy delivered.
Electricity rates can be seen reaching $14,000 per MW during
those FCAS periods.
Now Renewecomy reports that FCAS were required on January 14,
but the prices didn’t skyrocket to $14,000 per MW and they
instead were maintained at around $270/MW after a short spike.
The bidding of Tesla’s 100MW/ 129MWh Powerpack project in South
Australia on the services is credited with escaping the price
hike, which would have cost energy generator and consumers
millions in costs.
The Powerpack system is able to switch from charging to
discharging in a fraction of a second, which allows Neoen, the
operator of the system, to quickly respond when frequency issues
happen.
Ed McManus, the CEO of Meridian Australia and Powershop
Australia, told Renewecomy about the situation on the Energy
Insiders podcast:
[quote]“If you look at FCAS … the costs traditionally in South
Australia have been high …. and our costs in the last couple of
years have gone from low five-figures annually to low
six-figures annually. It’s a hell of a jump,”
“That plays into the thinking of new players looking to come
into South Australia to challenge the incumbents. FCAS charges
are on their minds.
“It’s a little early to tell, but it looks like from preliminary
data looks that the Tesla big battery is having an impact on
FCAS costs, bringing them down … that is a very, very
significant development for generation investment and generation
competition in South Australia.
“The South Australian government deserves a big pat on the back
…. they have received a fair bit of flack – people saying if the
power goes out, the battery can only power state for 5 minutes –
but that is kind of irrelevant.
“The battery is there to do other things … and it looks like it
has been phenomenally successful in doing that.”[/quote]
The government didn’t wait for a pat on the back and it instead
quickly contracted Tesla for another giant energy storage
project. ;D
We reported this weekend that Tesla will be installing
Powerwalls and solar power on 50,000 homes to create the biggest
virtual power plant in the world.
The project would result in 250 MW and 650 MWh of capacity,
which could also be used for similar services as Tesla’s giant
Powerpack installation but distributed in residential
communities.
