[center]Eneco and Mitsubishi Corporation construct largest
battery in Europe

JARDELUND, 06 April 2017
bess
Eneco and Mitsubishi Corporation (MC) are going to construct,
under the name EnspireME, the largest battery system in Europe.
This battery system will be located in Germany and enables the
companies to supply sustainable reserve capacity to the European
electricity grid. Both parties will also start a pilot project
involving the storage of locally produced surplus wind energy.
In connection with the ‘Energiewende’, Germany is a frontrunner
in increasing the sustainability of its energy supply. As a
result, an increasing number of wind turbines and solar panels
are taking over the production of electricity from existing
fossil fuel power plants. However, these plants continue to play
a role in the form of supplying reserve capacity that is needed
to balance the power grid. The battery system will be able to
take over the role of primary reserve provider and, thus, forms
a sustainable alternative for the backup supplied by coal and
gas fired power plants.
Jardelund
Eneco and MC will start the construction of the battery system
in the Summer. The battery will be located next to a substation
in the municipality of Jardelund in Schleswig-Holstein, close to
the border with Denmark. Schleswig-Holstein is one of the
leading federal states contributing strongly towards a
successful ‘Energiewende’ in Germany. It is the place where
electricity generated by large wind farms is collected and
transmitted to other parts of Germany.The proximity of the
substation has the advantage that the battery can play a role in
reducing the regular loss of energy at these stations.
Initially, the battery will be used for the primary reserve
market, where the German transmission network operators purchase
the reserve capacity they require to guarantee the 50 Hertz
frequency on the grid.
[Pilot project
With the support of the German federal state of
Schleswig-Holstein, Eneco and MC will start a pilot project that
will involve the connection of nearby wind farms to the battery
system. If there is surplus capacity or an overload on the grid,
these wind farms will be able to temporarily supply their
electricity output to the battery system. This will not only
reduce the load on the grid, but also has a financial advantage
as the owners of the wind farms will be able to offer the stored
electricity to the market at a more favourable moment.
Energy storage technology
The battery is a Lithium-Ion system of 48 MW and a capacity of
over 50 MWh, which corresponds to the average daily energy
consumption of over 5.300 German households. The battery system,
including the power conversion system and controls, will be
supplied and integrated by NEC Energy Solutions, a large energy
storage system integrator. It is expected that the battery
system will be put into operation at the end of 2017.
Hiroshi Sakuma, Group Chief Executive Officer, Mitsubishi
Corporation: 'We have been strengthening our activity in the
renewable energy field in order to contribute to a low-carbon
society. We believe that energy storage will become a key
factor, given the circumstance that energy volatility is
expanding as the result of the rapid increase of renewable
energy. This project is a significant step forward to the
realisation of the sustainable society.'
Kees-Jan Rameau, Chief Strategic Growth Officer Eneco Group:
'Although, fortunately, the share of sustainable energy is
increasing rapidly, it does pose a challenge for the energy
grid. In our view, the solution to this is twofold: smart
matching of supply and demand and a combination of small-scale
and large-scale energy storage. Last year, we initiated the
creation of a network of home batteries for consumers. In
collaboration with Mitsubishi Corporation, we are now also
making significant progress in the area of large-scale
sustainable storage. Germany is a frontrunner in green
development and, as such, ideal for gaining experience. This
step will also provide valuable knowledge that can be applied on
the Dutch market.'

[center]Seaweed Could Revolutionize How We Power Our Devices
HTML http://www.pic4ever.com/images/128fs318181.gif
[/center]
The answer to powering our devices might have been hiding in our
sushi all along ;D. An international team of researchers has
used seaweed to create a material that can enhance the
performance of superconductors, lithium-ion batteries and fuel
cells.
----------------------------------------------------------------
----------------
The team, from the U.S., the UK, China and Belgium, came up with
the idea to mimic Murray's Law, which is a natural process
within the structure of a plant's pores that pumps water or air
throughout the plant to provide it energy. With Murray's law,
the larger the pore, the less energy expended because the
pressure is reduced, but it takes different variations in size
to create a balancing act across the body of the plant and
maximize energy potential. In seaweed's case, the plant has the
perfect pore variation for regulating energy in real world
applications.
"The introduction of the concept of Murray's Law to industrial
processes could revolutionize the design of reactors with highly
enhanced efficiency, minimum energy, time and raw material
consumption for a sustainable future," said Bao-Lian Su,
professor at the University of Cambridge and co-author of the
research.
The scientists made the "Murray material" by embedding an
extract of the seaweed into multiple layers of nano-fibers of
zinc oxide, which created a hierarchy in the size of the pores.
They believe the material can be used on rechargeable batteries,
high performance gas sensing technology or even to decompose
inorganic material in the oceans.

Seaweed is a fast growing algae that grows in abundance in
coastal areas. It is estimated that seaweed and other algae
takes up 90 percent of all plant life on Earth, making it a very
sustainable plant for energy purposes. The team believes they
could safely utilize 20,000 tons of the seaweed extract per
year.
The Murray material could improve capacity by 25 times compared
to the current graphite-based technology being used in
lithium-ion batteries. The pores in the material also allow for
a smoother charge/discharge process, improving stability and
extending the life of batteries or fuel cells.
"Large scale manufacturability of this porous material is
possible," said co-author Tawfique Hasan, also at Cambridge.
"Making it an exciting, enabling technology, with potential
impact across many applications."

eggs in your energy production basket. AND, those hydrocarbons
must be obtained cleanly, not through dirty drilling or mining.
Only IDIOTS that defend fossil fuels as a "cheap" and "energy

Power grid operator Tennet and household power storage provider
Sonnen plan to use a network of small-scale batteries to help
reduce costs caused by grid bottlenecks between Germany’s windy
North and the power-hungry South, reports Michael Bauchmüller in
Süddeutsche Zeitung. “We want to integrate renewable power in
the best possible way,” Tennet board chair Urban Keussen told
the newspaper. [quote]“We can manage that not only with copper,
but also [i]with intelligence[/i].” [/quote]Sonnen managing
director Philipp Schröder said that in a first stage, 6,000
batteries would be used to optimise the power grid. Households
making their batteries available for the project, which will use
blockchain encryption technology, will receive free power,
according to the article. Keussen told newspaper Die Welt the
use of blockchain was “the first step into a new energy world.”

U.S. Reps. Chris Collins (R-N.Y.) :o ;D and Mark Takano
(D-Calif.) yesterday launched the Advanced Energy Storage Caucus
in Congress to educate Members of Congress regarding the
benefits of storage to the U.S. electric system and investigate
ways to accelerate job growth and investment in U.S. advanced
energy storage industries.
The Energy Storage Association (ESA) said that Collins and
Takano were joined for the launch by executives from leading
utilities, developers, and manufacturers of storage
technologies, including AES Energy Storage, S&C Electric, Stem
Inc., and National Grid.
In addition, the caucus will periodically brief members of
Congress on how energy storage is reshaping the way electricity
is generated, distributed, and consumed, and how policy can
remove impediments to greater use of battery storage.
"We need bipartisan solutions to help address our aging energy
infrastructure," Collins said in a statement. “Energy storage
technology will grow our economy and make sure American
businesses can compete around the globe.”

By Renewable Energy World Editors solar
Virginia Gov. Terry McAuliffe yesterday signed a bill
authorizing the expansion of the state’s Solar Energy
Development Authority to include energy storage.
The legislation is part of a series of bills signed by McAuliffe
that promote wind, solar and energy storage technologies. [img

/>
SB 1258, introduced by Sen. Adam Ebbin, expands the purpose of
the new Solar Energy and Battery Storage Development Authority
to include positioning the state as a leader in research,
development, commercialization, manufacturing, and deployment of
energy storage technology.
The powers of the authority are expanded to include
•Promoting collaborative efforts among Virginia's public and
private institutions of higher education in research,
development, and commercialization efforts related to energy
storage,
•Monitoring relevant developments nationally and globally,
•Identifying and working with the state’s industries and
nonprofit partners.
In addition, the measure expands the size of the authority 11 to
15 members.
“Today, I am honored to sign these bills into law, furthering
the great work we’re doing to support and promote the clean
energy sector across the Commonwealth,” McAuliffe said at the
bill signing ceremony, according to the governor’s office. “It
is clear that Virginia is moving in the right direction,
especially with the recent announcement of record growth in our
solar industry, but there is still work to do. Together, with
our partners in the General Assembly and the private sector, I
will continue to implement policies that bolster the entire
clean energy industry in the Commonwealth.”
The governor’s office said that other bills pertaining to
renewables that were signed by McAuliffe yesterday include:
•SB 1393, which creates a path for the development of community
solar programs in the service territories of Appalachian Power
Company (ApCo), Dominion, and the Electric Cooperatives. Each
utility will develop its own territory-specific program that
allows citizens and businesses the ability to “subscribe” to
receive electricity generated by a small centrally-located solar
generation system.
•SB 1394 and HB 2303, which are identical bills, create a Small
Agricultural Generators Program — a new framework for the
generation of renewable energy at agricultural facilities and
how that energy can be sold to utilities.
•SB 1395 increases the allowable maximum size of renewable
projects to be eligible to be permitted through the state’s
Permit by Rule (PBR) process from 100 MW to 125 MW. These
projects are exempt from environmental review and permitting by
the State Corporation Commission. SB 1395 also exempts projects
that are being built for use by a single customer of a utility
from having to apply for and receive a Certificate of Public
Convenience and Necessity from the SCC.

California: 'We Are Just Getting Started' [img
width=70]
HTML http://www.pic4ever.com/images/muscular.gif[/img]
May 11, 2017
By Jason Deign energy storage
If you thought California’s lead as an energy storage market
might fade in the face of upstarts such as Australia or Germany,
then think again. Recent moves might see new gigawatts of
capacity being installed across the state by 2020.
The most significant development was the recent reopening of
California’s Self-Generation Incentive Program (SGIP) with more
than US$448m in funding dedicated to energy storage.
The cash, 79 percent of an almost $567m funding package
available through 2019, is expected to create a surge in
behind-the-meter energy storage deployments across the state.
Most of the storage budget is aimed at what the California
Public Utilities Commission (CPUC) calls ‘large-scale storage,’
or systems of more than 10 kW. But 13 percent, or just over
$57m, will be for residential installations.
“The incentive level for energy storage systems larger than 10
kW that do not take the investment tax credit (ITC) and all
residential systems 10 kW and smaller will be set at 50
cents/watt-hour,” says the CPUC on its website.
Projects That Are Larger than 10 kW
“Projects that are larger than 10 kW and take the ITC will have
a lower initial incentive rate of 36 cents/watt-hour.
“We expect that demand will exceed the amount of funding for
incentives at that level very quickly, and we therefore expect
incentive levels to decrease by 10 cents/watt-hour shortly after
SGIP reopens.”
The new SGIP will act in addition to a provision for
behind-the-meter storage that already exists within the Assembly
Bill 2514 (AB 2514) mandate that has powered deployments in
California so far.
The AB 2514 provision is for 200 MW of capacity, to be procured
by 2020 and installed by 2024.
But the SGIP, which had its budget doubled under legislation
agreed last year, “is going to blow it out of the water,” said
Janice Lin, founder and executive director of the California
Energy Storage Alliance (CESA).
Instrumental In Getting the SGIP to Focus on Storage
CESA was instrumental in getting the CPUC to focus the SGIP on
storage, she told Energy Storage Report. Originally the program
had been solely dedicated to demand response, she said.
Behind-the-meter deployments are also being boosted in
California by AB 2868. This last year directed the CPUC to get
the state’s three largest electrical utilities to “accelerate
widespread deployment of distributed energy storage.”
In practice this will add up to 500 MW more of capacity to the
system, up to 25 percent of which could be behind the meter.
“We’re waiting for those utility applications,” Lin said.
On top of that, AB 2514, which is a biennial procurement
program, is set to continue and is expected to mandate further
utility deployments in future. But it doesn’t stop there.
This legislative session has seen no fewer than three bills
emerge in the last fortnight that could each add significant
further energy storage capacity to the California electricity
system.
Procuring 120 MW of Energy Storage Capacity
One is a Senate Bill, SB 801, which requires the Los Angeles
Department of Water and Power and Southern California Edison to
procure 100 MW and 20 MW, respectively, of energy storage
capacity.
The procurement has been put forward on an emergency basis to
reduce the impact of the Aliso Canyon natural gas storage
failure.
Finally, two other bills, SB 338 and AB 1405, aim to address
California’s clean peak energy problem, commonly known as the
duck curve. “The neck of the duck is the most challenging
portion of our net load,” explained Lin.
And it’s getting worse. This month the California Independent
System Operator (CAISO) “is expected to release a new animal,”
she said. “What I’ve heard from CAISO is the ramp of the new
duck is shocking. The neck is huge.”
CAISO now sees storage as a key tool for dealing with challenges
such as the duck curve and Aliso Canyon, she said.
If Clean Peak Energy Bills Are Implemented
If the clean peak energy bills are implemented it is unclear how
much extra energy storage capacity they might add since other
measures, such as demand response, might form part of any
eventual package.
However, CESA roughly calculates that it could amount to
“hundreds of megawatts of storage,” said Lin. “The fundamental
underlying trends are very solid for storage.
“Storage is a very helpful enabler to more and more clean energy
in our mix,” she said. “There is a lot going on in California
right now. While California has been trailblazing, in some ways
we are just getting started.”

[center]Vehicle-To-Grid Discharge, Even At Constant Power, Is
Detrimental To EV Battery Performance, Study Finds :([/center]
May 16th, 2017 by James Ayre
SNIPPET:
There have long been critics of the idea of widespread use of
electric vehicle (EV) vehicle-to-grid (V2G) technologies for a
variety of reasons, but largely in relation to the potential
damage done to EV batteries, and thus reduced battery lifespan.
New research from the Hawaii Natural Energy Institute at the
University of Hawaii at Manoa seems to clearly support this
assertion — the extra cycling that accompanies use of an EV
battery for grid balancing, even when at constant power, reduces
EV battery cell performance significantly.
To be more specific, the use of an EV with V2G tech could reduce
the working lifespan of an EV battery pack to under 5 years
time, according to the new work. :( :P
The researchers note, though, that simply delaying the charging
of EVs as a means of balancing the grid would have only a
“negligible” effect on EV batteries, and could thus represent a
better option. However, this could prove to not be the case in
environments warmer than “room temperature.”

Agelbert COMMENT: Well, provided this is true, EV car
manufacturers should use common sense and join with electric
Utilities to offer EV car buyers a 10 year guarantee, WITHOUT
ANY ADDED CHARGES, for replacing the used battery pack with a
new one. I make the caveat about "no added charges" because the
fun and games on the average lead acid battery "guarantee" is,
and always was, a rip off.
Avoiding peaking costs is well worth the 10 year battery pack
guarantee. In fact, if we had a sane government, they would
REMOVE all the fossil fuel "subsidies" and, instead provide EV
battery pack 10 year guarantee subsidies as a matter of National
Security grid stability.
But common sense and logic in regard to renewable energy is
rather difficult for the United Petro-States of America.

A useful warning to users of today's batteries but of limited
relevance to their successors which, if anything, will be
encouraged by the disclosure of another flaw awaiting correction
in a key component of a product which is still at a very early
stage of evolution.
agelbert > wattleberry
Like what, the tendrils that grow and short them? We know about
that. The battery development is quite mature, thank you very
much. It's the fossil fuel polluting machine called an internal
combustion engine that never got past the profit over people and
planet stage. Gas stations will soon go the way of the dodo bird
too.
The only issue with batteries of any significance that needs
improvement is rapid replacement technology. We NOW have access
to electricity in FAR more places than we have access to
gasoline. All we need is a small "spare" battery pack that can
take us home or too a quick pack replacement location nearby if
our main battery pack fails.

This discussion needs more clarity. People are defining whats
better in odd ways. How do we define it? By how much the EV
owner saves in retail electricity costs vs how much the value of
the car is reduced by battery degeneration?
I tend to feel V2G doesn't make sense, because a car is not just
a battery. However, when the battery is used more, the value of
the car reduces.
If you want V2G, get a PowerWall instead. Then you are only
reducing the value of the PowerWall, not the car.
A PowerWall is 6500. A Model S is > 65000. 10x.
Now on the other hand, we are only looking at one storage
scenario, load shifting.
Already, California is starting a demand response program that
pays users not to use electricity during peaks and allow the
utility to dial back demand when it needs to.
That is an area for an EV owner to benefit by allowing charging
to be controlled or timed to miss expensive peak demand times.
That makes total sense.

Since the sun does not shine at night we need a way to store
daytime-generated solar energy. Net metering is an elegant and
100% efficient way to shift excess solar power, but that system
will not work at high solar penetration levels. Never mind the
fact that utilities are loath to allow their customers to
generate electricity for less than it costs them to deliver this
power.
As a result, battery storage is on the minds of almost all new
solar customers. Storage technology, incentives, favorable
electric rates and control software are all evolving rapidly.
There are currently about a dozen companies with battery storage
systems designed for use with rooftop solar. Like peanut butter
and chocolate, many solar companies are starting to offer
battery storage systems along with their solar systems.
My advice is to proceed with caution. Even though off-grid
battery storage systems have been available for years, we are at
the very early stages of grid-tied solar combined with battery
storage. From a hardware standpoint, battery storage costs are
plummeting, and new inverters/charge controllers are being
developed. Perhaps more importantly, software that will
efficiently interact with solar, batteries, the grid and your
home energy consumption still has limited functionality. For
more about the practicalities of home battery storage, Listen Up
to this week’s Energy Show on Renewable Energy World.

About the Energy Show[/b]
As energy costs consume more and more of our hard-earned
dollars, we as consumers really start to pay attention. But we
don't have to resign ourselves to $5/gallon gas prices,
$200/month electric bills and $500 heating bills. There are
literally hundreds of products, tricks and techniques that we
can use to dramatically reduce these costs — very affordably.
The Energy Show on Renewable Energy World is a weekly 20-minute
podcast that provides tips and advice to reduce your home and
business energy consumption. Every week we'll cover topics that
will help cut your energy bill, explain new products and
technologies in plain English, and cut through the hype so that
you can make smart and cost-effective energy choices.
About Your Host
Barry Cinnamon is a long-time advocate of renewable energy and
is a widely recognized solar power expert. In 2001 he founded
Akeena Solar — which grew to become the largest national
residential solar installer by the middle of the last decade
with over 10,000 rooftop customers coast to coast. He partnered
with Westinghouse to create Westinghouse Solar in 2010, and sold
the company in 2012.
His pioneering work on reducing costs of rooftop solar power
systems include Andalay, the first solar panel with integrated
racking, grounding and wiring; the first UL listed AC solar
panel; and the first fully “plug and play” AC solar panel. His
current efforts are focused on reducing the soft costs for solar
power systems, which cause system prices in the U.S. to be
double those of Germany.
Although Barry may be known for his outspoken work in the solar
industry, he has hands-on experience with a wide range of energy
saving technologies. He's been doing residential energy audits
since the punch card days, developed one of the first
ground-source heat pumps in the early ‘80s, and always abides by
the Laws of Thermodynamics. ;D
