April 28, 2022: Gross sales of energy storage programs in Germany rose by greater than 25% in 2021 in comparison with the earlier 12 months, producing a turnover of practically €9 billion (about $9.6 billion), in accordance with provisional knowledge introduced on April 6.

The Germany Energy Storage Affiliation (BVES) stated the expansion in home and worldwide revenues of corporations registered within the nation was achieved regardless of a sluggish industrial restoration from pandemic lockdowns and within the face of provide shortages and rising manufacturing and uncooked materials prices.

A want for higher energy independence, extra sustainability and electromobility “are clearly changing into market drivers”, BVES stated.

The residential storage market phase recorded the most important rise, with greater than €4 billion in gross sales in 2021 — a 28% improve over the earlier 12 months, in accordance with the survey carried out for BVES by Energie Consulting.

‘Nice consequence’

And the variety of staff in Germany’s energy storage enterprise elevated from 14,700 in 2020 to just about 17,000 in 2021, in accordance with the provisional figures.

The affiliation forecast that the variety of house storage programs put in by the top of April 2022 will attain 500,000, including: “With an put in capability of over 2.5GW, this corresponds to the capability of virtually two nuclear energy vegetation.”

Energy storage customers seek reassurance on fire safety after ‘high profile failures’



Energy storage customers seek reassurance on fire safety after ‘high profile failures’

Battery storage system security was on the high of the agenda for a lot of distributors and their prospects at ees Europe final week.

{The electrical} energy storage commerce occasion passed off alongside Intersolar Europe and different strands referring to electric autos (EVs) and different good and clear energy trade sectors and applied sciences, at Messe Munchen in Munich, Germany.

Whereas there have been many attention-grabbing merchandise on present and numerous large image matters mentioned – like the necessity for coherent policy strategies at EU level on energy storage and the continued provide chain crunch – numerous sources commented that the lithium battery storage trade’s must reassure stakeholders on the subject of fireplace security is paramount.

“As a way to actually play an necessary position in our energy and skill, future batteries must be protected. It’s dangerous for the trade if persons are involved about battery security,” Kai-Philip Kairies of battery analytics specialist ACCURE Battery Intelligence tells Energy-Storage.information.

ACCURE’s software program may help monitor and assess how batteries in EVs and battery energy storage techniques (BESS) are performing, how they’re growing old and the way safely they’re working. Of these three primary options of the analytics suite, security has gotten probably the most consideration recently, Kairies, a battery expert-turned startup CEO, says.

There have been some “excessive profile failures,” that embody the fireplace at Tesla’s Victorian Big Battery in Australia and the overheating incident at Moss Landing Energy Storage Facility in California: respectively the largest BESS tasks in Australia and the world.

Most just lately there was additionally hearth reported at a 10MW/40MWh BESS installed for utility Salt River Project (SRP) in Arizona. Germany’s dwelling energy storage system market can be quickly rising and Kairies says he is aware of of 5 fires at residential techniques reported up to now month alone.

Whereas fortunately it seems that nobody has been injured by any of these incidents they usually stay uncommon relative to the sheer volumes of battery storage being put in all over the world, nobody — least of all prospects or most of the people — will be taking them calmly.

Battery storage producer Saft has been delivering containerised techniques to international markets since 2010. It has by no means skilled any critical failures of apparatus which have precipitated fires, a monitor report that the corporate’s VP for improvements and options, Michael Lippert, stated it’s pleased with.

Nonetheless, there’s nonetheless a possible danger concerned and one ought to “by no means say by no means” relating to security assessments. Lippert says that for Saft, important security concerns wanted to be thought of holistically and in-built from the very begin of labor to design the corporate’s grid-scale battery product, Intensium Max.

A method through which Saft’s strategy might differ from its rivals is that the Intensium Max is a standardised, repeatable product that doesn’t basically change in design from venture to venture.

“From the very starting, we’ve got made a danger evaluation of any attainable danger. This consists of issues just like the impact of the cooling system, we’ll embody humidity resulting from condensation, for instance, which is a danger as a result of in a 1500 Volt system, any humidity can create leaking energy,” Lippert says.

“We make it possible for earlier than you open your [container] door, we set the temperature past the condensation level. So, there are various issues we’ve got thought by to start with in the direction of [enhancing] functionalities, but in addition security.”

Saft’s system design integrates a mixture of detection techniques, hearth suppression and hazard administration that Lippert claims is “fairly distinctive on this planet”.

Intensium Max, the constructing blocks of all Saft’s tasks, comprises two unbiased hearth suppression techniques. The corporate has additionally realized, from seeing incidents happen at different makers’ tasks, that there’s a want for administration of the gases that may trigger explosions if constructed up inside containers.

“We pay lots of consideration to creating positive that the operator, but in addition hearth brigades that may intervene are aware of these gadgets they usually have the instruments to make the suitable resolution. Which suggests they don’t must open the container to see what is occurring, they’ve the coaching, they usually have the diagnostic instruments outdoors to see the temperature, to see whether or not there’s an explosive environment.”

Evolving security applied sciences

INTILION, a battery storage producer headquartered in Germany, was unveiling a brand new prototype BESS for the business and industrial (C&I) market, with an inbuilt hearth security function.

The numerous benefits that lithium-ion batteries have, additionally include “attribute hearth and explosion dangers,” which imply a lithium hearth can’t be extinguished, INTILION product supervisor Martin Peters says.

There are three primary causes of fires: electrical dangers from overvoltage, overcurrent or overheating, thermal dangers from excessive temperatures outdoors the battery system and mechanical dangers that come from bodily injury or manufacturing defects which may’t be readily recognized externally.

“Perhaps over time of utilization, you’ve gotten some points within the cells. Dendrites on the plates may very well be growing, resulting in a cell inner brief circuit, which then results in thermal runaway after which propagation.”

Within the German market, battery techniques for indoor use want to fulfill certification requirements set by VDE. These embody necessities that no hearth can unfold or propagate between neighbouring battery modules and that there ought to be no flames outdoors the module.  

INTILION has designed an extra housing to go round every module, with calculated air channels that route any gases launched in an outlined method. The gasoline is subsequently compressed sufficient to not be flammable, and the gases are vented from the entrance of the unit.

The prototype has been licensed by a laboratory in Germany. Peters says the fireplace danger from lithium batteries can’t be utterly eradicated, however the injury will be restricted to only one module. The INTILION system additionally features a tray to gather any leaked electrolyte, stopping contamination of groundwater.

As soon as techniques are literally within the subject, battery knowledge will be an efficient instrument in preventive upkeep, ACCURE’s Kai-Philipp Kairies says.

“Each battery has a BMS, a battery administration system, that generates some knowledge like voltage, present and temperature and we use that knowledge to mainly reverse engineer what’s taking place inside the battery,” Kairies says.

There are particular “interior states” of battery well being that may’t instantly be measured, will be calculated. Relying on how these interior states develop over time, ACCURE is ready to choose if a battery module or cell’s efficiency is wholesome, and much like the remainder of the pack.

If the analytics software program signifies that one battery reveals indications of plating, for instance, that battery will be pulled out of operation earlier than it turns into harmful. With over 1.5GWh of property beneath administration throughout the EV and ESS sectors, ACCURE proves this may be performed at scale, Kairies says, making certain the security of this and the subsequent era of lithium battery storage techniques.

Batteries are number one at maintaining Australia’s grid frequency



Batteries are number one at maintaining Australia’s grid frequency

Battery storage has turn out to be the main supplier of frequency management ancillary providers (FCAS) within the Nationwide Electrical energy Market (NEM) which covers most of Australia.

That’s in accordance with quarterly figures launched by the Australian Energy Market Operator (AEMO). The most recent version of AEMO’s Quarterly Energy Dynamics report covers the interval from 1 January to 31 March 2022, highlighting details, statistics and the tendencies which are shaping the NEM’s dynamics.

For the primary time ever, the biggest proportion of frequency regulation offered by expertise sort got here from battery energy storage techniques (BESS), with a 31% market share throughout the eight totally different FCAS markets. It was a full 10% lead over black coal and hydro which tied for second place with a 21% share every.

Whole estimated web revenues for batteries within the NEM have been round A$12 million (US$8.3 million) for the primary quarter – an increase of A$2 million year-on-year from A$10 million netted in Q1 2021. It was a dip from revenues raised throughout the remainder of final yr, however comparisons maybe are typically fairer with equal quarters as a consequence of seasonality of electrical energy demand patterns.

On the identical time, the price of offering frequency management fell to about A$43 million, which was a couple of third the price recorded in Q2, Q3 and This autumn 2021 and about the identical as was recorded in Q1 2021. This discount was nonetheless largely pushed by the impression of transmission system upgrades in Queensland which had led to excessive contingency FCAS costs for the state as scheduled outages happened within the three previous quarters.

Whereas batteries took first place in FCAS, different comparatively new frequency regulation sources similar to demand response and digital energy vegetation (VPPs) have additionally began to eat into the share offered by typical technology, AEMO famous.

Picture: AEMO

Batteries getting used for energy in addition to energy

Maybe the largest takeaway for the energy storage business is that the share of revenues earned by FCAS is the truth is on the identical time lowering relative to these earned by energy markets.

Within the final couple of years, frequency has been by far the biggest revenue-earner for battery storage, with energy purposes like arbitrage a means behind. In a current article for our quarterly technical journal, PV Tech Energy, Ben Cerini, managing guide at energy market professional group Cornwall Perception Australia, mentioned that about 80-90% of battery revenues have been coming from FCAS and about 10-20% from energy trading.

In Q1 2022 nonetheless, AEMO discovered that the proportion gross revenues earned within the energy market by batteries jumped from 24% in Q1 2021 to 49%.

A number of new massive initiatives drove this enhance in share, just like the 300MW/450MWh Victorian Huge Battery in Victoria and the Wallgrove 50MW/75MWh battery system in Sydney, New South Wales.

AEMO famous than in Victoria, volume-weighted energy arbitrage worth rose from A$18/MWh to A$95/MWh in comparison with Q1 2021.

Pumped hydro energy storage (PHES) additionally had a robust quarter: a document quarterly excessive A$56.5 million of spot market income was earned, in comparison with simply A$2.9 million in Q1 2021.

This was largely pushed by the efficiency of Wivenhoe pumped hydro plant in Queensland, which made some huge cash as a consequence of excessive electrical energy value volatility within the state in the course of the quarter. The plant noticed its utilisation enhance 551% from Q1 2021 and was capable of at occasions receives a commission at spot costs larger than A$300/MWh. Simply three days of extraordinarily unstable pricing earned the plant 74% of its quarterly income.

Basic market drivers imply Australia is poised for robust development in energy storage capability. The nation’s first new pumped storage plant in nearly 40 years is under construction and extra are prone to observe. It’s in batteries although that the quickest and largest development in exercise is anticipated.

Approval granted for ‘coal substitute’ BESS in NSW

AEMO mentioned that whereas there at the moment are 611MW of BESS working within the NEM, there are 26,790MW of proposed new battery storage initiatives.

A type of is the Eraring mission in New South Wales, a BESS with as much as 700MW output and 4 hours’ length (2,800MWh), proposed by main built-in energy retailer and generator Origin Energy.

The mission can be constructed on the website of Origin’s Eraring 2,880MW black coal energy plant, which the company is keen to place into retirement by 2025. Its function within the native energy combine would get replaced by the BESS, 2GW of aggregated digital energy plant capability and different sources together with Origin’s present fleet of thermal technology.

Origin identified that coal is being outcompeted by renewables, energy storage and different extra trendy applied sciences within the evolving market buildings of the NEM.

Origin introduced late final week that the NSW authorities Division of Planning and Setting has given planning approval for the BESS mission, making it the biggest mission of its sort within the nation to have gotten to that time.
